Use of Autochthonous Organic Inputs for Amelioration of Fluoride Toxicity and...Agriculture Journal IJOEAR
Abstract— An assessment was undertaken to study the combating capacity of autochthonous organic inputs viz. vermicompost, compost and bacterial consortia isolated from different sources viz. oil spillage sludge of petrol pump and rhizosphere of rice plant against the fluoride toxicity under field condition. Brassica campestris L. cv.B9 was selected as a test species. Experiments were carried out in two consecutive years 2012-2013 and 2013-2014 designed as experiment I and experiment II. One unique thing was observed that mustard which were grown under indigenous organic inputs treated plots gave maximum yield under T1 treatment (25 mg Kg-1 F) and was above the control set. Moreover, autochthonous organic inputs were capable of reducing the amount of fluoride content within the different plant parts of mustard. Maximum amount of fluoride was accumulated within the leaves and minimum quantity of fluoride was accumulated within the seed but within the permissible range (< 0.3 mg Kg-1 as recommended by EPA, FAO and WHO). Data were significantly different at 5% level using Duncan’s Multiple Range Test (DMRT). Therefore, combination of vermicompost, compost and bacterial consortia acted upon reduction of fluoride level in the crop field of mustard.
Siderophores are compounds from ancient Greek words, sidero ‘iron’ and phore ‘carriers’ meaning ‘iron carriers’. These are low-molecular-weight iron-chelating compounds, produced by ‘rhizospheric bacteria’ under iron-limited conditions. They are small, high affinity iron chelating compounds secreted by microorganisms such as bacteria, fungi etc. Siderophore usually form a stable hexahendate, octahedral complex with Fe3+.

Integrated Nutrient Management refers to the maintenance of soil fertility and of plant nutrient supply at an optimum level for sustaining the desired productivity through optimization of the benefits from all possible sources of organic, inorganic and biological components in an integrated manner
Integrated nutrient management (INM) involves efficient and judicious use of all the major components of plant nutrient sources for sustaining soil fertility, health and productivity
Integrated approach for plant nutrition is being advocated because single nutrient approach often reduces fertilizer use efficiency and consequently creates problem fertilizers can help in enhancing and maintaining stability in production with least degradation in chemical and physical properties of the soil.
A healthy soil is a living, dynamic ecosystem that performs many vital functions.
A healthy soil produces a healthy feed for consumption. Improved soil health often is indicated by improvement on physical, chemical and microbiological environment.
Introduction of high yielding varieties, irrigation and use of high analysis fertilizer without proper soil tests, accelerated the mining of native soil nutrient resources.
Under intensive cultivation without giving due consideration to nutrient requirement has resulted in decline in soil fertility and consequent productivity of crops
Vegetables are rich source of energy and nutrition.
Influence of Arbuscular Mycorrhizal Fungi, Green Manure of Leucaena leucoceph...BRNSS Publication Hub
White yam (Dioscorea rotundata) was planted in the abandoned quarry to determine the growth and yield effects of mycorrhizal fungi, green manure, and other soil amendments. Seed yams were planted on the heaps (1 m × 1 m) in three replicates and three blocks. Data collected were analyzed using analysis of variance and Duncan multiple range test. The results showed that Glomus mosseae, Glomus etunicatum, green manure of Gliricidia sepium (GS), poultry manure, and NPK fertilizer influence yam’s shoot, root, and tuber weights. It was further observed that the combined treatments of GS and Leucaena leucocephala had better enhancement of growth and yield characters of yam. Biofertilizers together with plant and animal remains are therefore recommended for the bioremediation of quarry and other areas affected by natural, human, or ecological activities.

Abstract: Exerting necessitated concentrations of Nitrate and fluoride to the organic highland cropping
systems is a vital management technique. All the chemical elements of the earth’s crust occur in widely differing
omnipresent concentrations, due to their different nuclear chemical formation and geochemical history. The use
of biological nitrogen and fluoride inputs complicates its balancing act due to dandier uncertainty in inorganic
Nitrogen and Fluoride availability. The growers to strike maintain Nitrogen provisioning to support crop
growth and retention of limit pollution followed by fluoride associated soils. Due to various activities of the man
in domestic field, agriculture area and industrial establishment the environment around us consisting soil, water
and air gets polluted. Fluoride inexhaustible concentrations forbid the growth of crop even though nitrates
reposit in the cultivated soils. The purpose of this project was to establish kinetics when nitro fluorides
associated in the highland soils to different crop systems towards environmental pollutions. Cordia Africana
and alfalfa are the plants which make soil to get enrichment of Nitrates and deescalate of concentrations of
fluorides from cultivated soils through its decomposition. This entire study went on its conventionally tilled
crops followed by Cordia Africana and alfalfa stems and leaf particles. Surface soil nitrate concentrations were
measured weekly, biweekly by volumetric analysis and nitrate leaching was estimated from tension Lysimeters
which were buried at the soil bedrock interface. Subsequently by using Orion 720A fluoride ion meter, deescalated
concentrations of fluorides have been measured. The demonstrated concentrations of Soil in NO3
variables, coefficients of variations from the mean concentrations across all samplings have been recorded
sporadically. The total area of the soil bed was maintained the same PH values until project was completed by
weigh Lysimeters. The timing of elevated Nitrate concentrations (10-15PPM) and the concentrations of fluoride
in deeper soil water corresponds with fallow periods. These dynamics will assist growers in adapting the timing
management operations and reduces nitrate departures.
Effect of biochar on maize yield and yield components in rainfed conditions |...Innspub Net
To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. The treatments were control, wheat straw biochar at 5t ha-1, and 10t ha-1, sugarcane bagasse biochar at 5t ha-1and 10t ha-1. The experiment was conducted in RCBD. Maize was grown in 4m × 6m sized plots. Soil samples were taken before sowing of crop for determination of soil pH, electrical conductivity, total organic carbon and texture. The plant parameters were grain yield, plant biomass, macro nutrients and micro nutrients. Wheat straw biochar 10 t/ha showed an increase of 16.1% N, 38.8% P, 33% K, 28.9% biomass and 20.8% grain yield. Sugarcane bagasse biochar at a rate of 10 t/ha showed significant increase of 14.9% N, 27.7% P, 30% K, 27.6% biomass and 22.1% grain yield. None of the biochar treatment showed any significant increase in micronutrient concentration in the plant.
Nutrient use efficiency (NUE) is a critically important concept in the evaluation of crop production systems. Many agricultural soils of the world are deficient in one or more of the essential nutrients to support healthy and productive plant growth. Efficiency can be defined in many ways and easily increased food production could be achieved by expanding the land area under crops and by increasing yields per unit area through intensive farming. Environmental nutrient use efficiency can be quite different than agronomic or economic efficiency and maximizing efficiency may not always be effective. Worldwide, elemental deficiencies for essential macro and micro nutrients and toxicities by Al, Mn, Fe, S, B, Cu, Mo, Cr, Cl, Na, and Si have been reported.
Studies the Effects of Imidacloprid on Enzymatic Activities in Clay Loam Soilijtsrd
In-vivo experiment was conducted for toxicity evaluation of Imidacloprid on soil enzyme activities arylsulphatase, acid-phosphatase and dehydrogenase activities in the treated soil under control condition for 60 days at different application rate 3.97µg mL FR , 7.94µg mL 2FR and 39.7µg mL 10FR . Imidacloprid has significant toxic at 2FR and 10FR doses but not on the recommended field rate FR . Acid phosphatase activity was stimulated at FR rate, whereas at higher dose 10FR inhibited the activity. A significant drop of dehydrogenase activity was observed irrespective of doses at 30 days of application and after that the enzymatic activity slowly increased. Application of Imidacloprid at FR to agriculture soil of Tripura is not likely to show any detrimental effects on soil acid phosphatase and dehydrogenase activities but at higher elevated doses there appear some harmful effects which was also very much transient.

Bioremediation Through The Use of Indigenous Natural Resources vis-a-vis Its ...Agriculture Journal IJOEAR
Abstract— An assessment was undertaken to study the combating capacity of bacterial consortia isolated from different sources viz. oil spillage sludge and water spillage of petrol pump and rhizosphere of rice plant against the fluoride toxicity under field condition. Oryza sativa was selected as a test species. The recommended doses of chemical fertilizers (70:35:35) and different concentration of sodium fluoride (25 , 50 , 100 , 200 , 300 , 400 and 500 mg Kg-1 F) were used for first set of experiment and the second set were treated with vermicompost, compost, bacterial consortia and different concentration of sodium fluoride(25 ; 50 , 100 , 200 , 300 , 400 and 500 mg Kg-1 F). Among all of the species Penicillium, Aspergillus and Fusarium were resistant and survived under fluoride polluted condition. One unique thing was observed from these experiment that paddy which were grown under indigenous organic inputs treated plots gave maximum yield under T1 treatment (25 mg Kg-1 F) which was above the control set. Moreover, stress enduring metabolites viz. proline content of flag leaves were lowest recorded under indigenous organic inputs treated plots as compared to chemical fertilizer treated plots. Data were significantly different at 5% level using Duncan’s Multiple Range Test. From the Air Pollution Tolerance Index (APTI) value of paddy clearly depicted that the crop of those plots were treated with indigenous organic inputs were more resistant for enduring stress condition. In these experiment combination of vermicompost, compost and bacterial consortia were capable of reducing the amount of fluoride within plant parts especially in grains (< 0.3 mg Kg-1 as recommended by EPA, FAO and WHO), where fluoride was within permissible range as well as they reduced the fluoride content within the soil (2.57-16.44 mg Kg-1. as recommended by FAO, EPA, and WHO) as was noted by measuring the fluoride in the plant parts and soil after the experiment. Therefore, bacterial consortia could be an alternative for bioremediation of fluoride.
Role of Organic and Inorganic Fertilizers on the Performance of Some Medicin...Premier Publishers
Medicinal plants are nutrient demanding plants for normal growth and to produce higher yield. The aim of this review is to assess and indicate the role of plant nutrients both organic and inorganic in some medicinal plants. Inorganic and/or organic fertilizers are needed to meet inadequate soil nutrients and the declining of soil fertility as a result of continuous cultivation. Maintaining soil organic matter concentration above the threshold level is critical for improving soil quality. A careful combination of organic and inorganic fertilizers is widely recognized strategy of integrated nutrient management to sustain agronomic productivity and improve soil fertility. The effects of organic fertilization and combined use of chemical and organic fertilizer on crop growth and soil fertility depend on the application rates and the nature of fertilizers used. Interestingly, applications of organic fertilizers to plants have been reported to increase the presence of bioactive compounds and antioxidants in them. On the other hand, inorganic fertilizers are crucial to increase the yield of medicinal plants like roselle within a short period of time. Most of the research conducted in plant nutrient demand for medicinal plants reported that integrated nutrient management for continuous and sustainable production of medicinal crop is necessary to gain quality products.
Soil is the largest carbon reservoir pool of terrestrial ecosystem and plays a key role in the global carbon budget and greenhouse effect. It contains 3.5% of the earth’s carbon reserve as compared with 1.7% in the atmosphere , 8.9% in the fossil fuels, 1.0% in the biota and 84.95% in the oceans. Soil reserves about 1550 GT of carbon as Soil Organic Carbon (SOC) and 1700 GT as carbonate carbon (Soil Inorganic Carbon , i,e SIC).Soil carbon(C) plays an important role in exchange of CO2 between atmosphere and biosphere. SOC and SIC are important as it determine ecosystem and agro-ecosystem functions influencing soil structure ,soil fertility ,water holding capacity , cation exchange capacity and other soil characteristics.
The portion of a plant left in the field after harvest of the crop that is (straw, stalks, stems, leaves, roots) not used domestically or sold commercially”. The non – economical plant parts that are left in the field after harvest and remains that are generated from packing sheds or that are discarded during crop processing. Organic recycling has to play a key role in achieving sustainability in agricultural production. Multipurpose uses of crop residue include, but are not limited to, animal feeding, soil mulching, bio-manure, thatching of rural homes and fuel for domestic and industrial use. Thus, crop residues are of tremendous value to the farmers. Crop residue benefit the soil physically, chemically as well as biologically.
Potassium is one of the essential major plant nutrient after nitrogen and phosphorus. Its management is more important since large amount of native k is mined by crops if it is not supplied externally. Role of potassium in increasing the yield of crops and improving the quality of produces has been in the agenda of soil scientists. It is seventh most common element in the lithosphere which contains on average 2.6% potassium.
The total potassium content of indian soils varies from 0.5 to 3.0%.Total potassium present in soils, more than 98% occurs in primary and secondary minerals.

Abstract— An assessment was undertaken to study the combating capacity of bacterial consortia isolated from different sources viz. oil spillage sludge and water spillage of petrol pump and rhizosphere of rice plant against the fluoride toxicity under field condition. Oryza sativa was selected as a test species. The recommended doses of chemical fertilizers (70:35:35) and different concentration of sodium fluoride (25 , 50 , 100 , 200 , 300 , 400 and 500 mg Kg-1 F) were used for first set of experiment and the second set were treated with vermicompost, compost, bacterial consortia and different concentration of sodium fluoride(25 ; 50 , 100 , 200 , 300 , 400 and 500 mg Kg-1 F). Among all of the species Penicillium, Aspergillus and Fusarium were resistant and survived under fluoride polluted condition. One unique thing was observed from these experiment that paddy which were grown under indigenous organic inputs treated plots gave maximum yield under T1 treatment (25 mg Kg-1 F) which was above the control set. Moreover, stress enduring metabolites viz. proline content of flag leaves were lowest recorded under indigenous organic inputs treated plots as compared to chemical fertilizer treated plots. Data were significantly different at 5% level using Duncan’s Multiple Range Test. From the Air Pollution Tolerance Index (APTI) value of paddy clearly depicted that the crop of those plots were treated with indigenous organic inputs were more resistant for enduring stress condition. In these experiment combination of vermicompost, compost and bacterial consortia were capable of reducing the amount of fluoride within plant parts especially in grains (< 0.3 mg Kg-1 as recommended by EPA, FAO and WHO), where fluoride was within permissible range as well as they reduced the fluoride content within the soil (2.57-16.44 mg Kg-1. as recommended by FAO, EPA, and WHO) as was noted by measuring the fluoride in the plant parts and soil after the experiment. Therefore, bacterial consortia could be an alternative for bioremediation of fluoride.
Role of Organic and Inorganic Fertilizers on the Performance of Some Medicin...Premier Publishers
Medicinal plants are nutrient demanding plants for normal growth and to produce higher yield. The aim of this review is to assess and indicate the role of plant nutrients both organic and inorganic in some medicinal plants. Inorganic and/or organic fertilizers are needed to meet inadequate soil nutrients and the declining of soil fertility as a result of continuous cultivation. Maintaining soil organic matter concentration above the threshold level is critical for improving soil quality. A careful combination of organic and inorganic fertilizers is widely recognized strategy of integrated nutrient management to sustain agronomic productivity and improve soil fertility. The effects of organic fertilization and combined use of chemical and organic fertilizer on crop growth and soil fertility depend on the application rates and the nature of fertilizers used. Interestingly, applications of organic fertilizers to plants have been reported to increase the presence of bioactive compounds and antioxidants in them. On the other hand, inorganic fertilizers are crucial to increase the yield of medicinal plants like roselle within a short period of time. Most of the research conducted in plant nutrient demand for medicinal plants reported that integrated nutrient management for continuous and sustainable production of medicinal crop is necessary to gain quality products.
Soil is the largest carbon reservoir pool of terrestrial ecosystem and plays a key role in the global carbon budget and greenhouse effect. It contains 3.5% of the earth’s carbon reserve as compared with 1.7% in the atmosphere , 8.9% in the fossil fuels, 1.0% in the biota and 84.95% in the oceans. Soil reserves about 1550 GT of carbon as Soil Organic Carbon (SOC) and 1700 GT as carbonate carbon (Soil Inorganic Carbon , i,e SIC).Soil carbon(C) plays an important role in exchange of CO2 between atmosphere and biosphere. SOC and SIC are important as it determine ecosystem and agro-ecosystem functions influencing soil structure ,soil fertility ,water holding capacity , cation exchange capacity and other soil characteristics.
The portion of a plant left in the field after harvest of the crop that is (straw, stalks, stems, leaves, roots) not used domestically or sold commercially”. The non – economical plant parts that are left in the field after harvest and remains that are generated from packing sheds or that are discarded during crop processing. Organic recycling has to play a key role in achieving sustainability in agricultural production. Multipurpose uses of crop residue include, but are not limited to, animal feeding, soil mulching, bio-manure, thatching of rural homes and fuel for domestic and industrial use. Thus, crop residues are of tremendous value to the farmers. Crop residue benefit the soil physically, chemically as well as biologically.
Potassium is one of the essential major plant nutrient after nitrogen and phosphorus. Its management is more important since large amount of native k is mined by crops if it is not supplied externally. Role of potassium in increasing the yield of crops and improving the quality of produces has been in the agenda of soil scientists. It is seventh most common element in the lithosphere which contains on average 2.6% potassium.
The total potassium content of indian soils varies from 0.5 to 3.0%.Total potassium present in soils, more than 98% occurs in primary and secondary minerals.
Effect of biochar on maize yield and yield components in rainfed conditions|I...Innspub Net
To investigate the maize yield and nutrient concentration in its leaves as affected by biochar from different organic materials (wheat straw and sugarcane bagasse), a field experiment was conducted on maize crop during 2013 at koont research farm chakwal. The treatments were control, wheat straw biochar at 5t ha-1, and 10t ha-1, sugarcane bagasse biochar at 5t ha-1and 10t ha-1. The experiment was conducted in RCBD. Maize was grown in 4m × 6m sized plots. Soil samples were taken before sowing of crop for determination of soil pH, electrical conductivity, total organic carbon and texture. The plant parameters were grain yield, plant biomass, macro nutrients and micro nutrients. Wheat straw biochar 10 t/ha showed an increase of 16.1% N, 38.8% P, 33% K, 28.9% biomass and 20.8% grain yield. Sugarcane bagasse biochar at a rate of 10 t/ha showed significant increase of 14.9% N, 27.7% P, 30% K, 27.6% biomass and 22.1% grain yield. None of the biochar treatment showed any significant increase in micronutrient concentration in plant.
Soil is a wonderful gift of nature for living creatures. It supports crop growth. It is an important environmental factor, and has a close reciprocal relationship with the plants growing in it and the soil microbes that exist in it. The forest soil consists of high humus with variety of microbes. In this experiment forest area of Newasa was selected for evaluation of nutrient status and bacterial population. On the basis of density of grasses Iseilema prostratum L, Setaria pumila (Poir.) Roem. & Schult, Aristida hystrix L., Dactyloctenium aegyptium (L.) Willd, Fimbriristylis miliacea (L.) Vahl. were selected. 100 soil samples from different locations from rhizosphere of these monocots were collected and analyzed for soil nutrient status and nitrogen fixing bacterial population. It was recorded that, out of five plants, the rhizosphere soil of Setaria pumila L. showed maximum bacterial population (11700540.00). Available nitrogen (320 kg/ha) and % organic carbon (0.60 %) followed by Setaria pumila (Poir.) Roem. & Schult the bacterial population was (2558265.00), available nitrogen (203 Kg/ha) and % Organic Carbon (0.59%). Other soil nutrients were also measured.
Impact of organic and conventional practices on, soil health and crop yield u...Agriculture Journal IJOEAR
Abstract— This study was carried out to evaluate the improvement of soil fertility and crop yield using formulated organic fertilizers in a Randomized Complete Block Design (RCBD) from October 2008 to April 2015 and the test crop was tomato, eggplant, cabbage and cauliflower. The physicochemical properties, behavior and persistence of plant beneficial microorganisms including nitrogen fixing bacteria, (e.g. Rhizobium sp., Azotobacter sp.), phosphate solubilizing bacteria e.g. (Bacillus sp. Pseudomonas sp., Phosphobacteria), Aspergillus sp. and Trichoderma sp., in the amended/ non-amended block were evaluated each year. The soil beneficial microbial populations and health properties including pH, nitrogen content, organic matter, phosphorus, K, Ca, and S, increased significantly in the compost-amended soils compared to the conventional practices. The total nitrogen (N) content and the organic matter of compost amended soil were 215% and 200% higher respectively than that of conventional practices (CP). Furthermore, significant increase of available organic matter, N, P, & K was observed in the compost-amended soils compared to conventional and control block. Furthermore, microbial population showed significant linear correlations with the organic matter contents of the soils and yearly vegetables yield increased gradually and was reached to almost identical to conventional field within 5 years, implying that the soil amended with BIOFER compost increased the soil fertility, and vegetables yields. Thus, application of BAOFER compost at the rate of 15 t/ha/year was found adequate in improving the vegetable yields and soil health in open field cultivation under subtropical climatic conditions.
Rock En Lenguas Originarias. Un Viaje Al Rock Tsotsil De Zinacantáninventionjournals
At the end of the eighties some young native people started playing rock in their own language, however, it was in the second half of the nineties when this genre exploded more clearly in two opposite regions of Mexico. At north, in the state of Sonora, emerged Hamac Caziim (Sacred Fire), who sing in Seri heavy metal rhythms. Meanwhile in the south, in the highlands of Chiapas, appeared Sak Tzevul (Lightning), alternative rock band singing in tsotsil.The following text is focused on the tsotsil rock of Zinacantan, where Lightning emerged and detonated in a movement of young people that began to sing in their native language. The historical construction it emphasizes on the emergence of new ways of being young in the context ofnative people, andthe musical and social transformations that have resulted from the introduction of rock.

The effects of cadmium and cow manure on nodulation and growth attributes of ...Agriculture Journal IJOEAR
Abstract— Different biotic and abiotic factors are involved in the availability of heavy metals in soil including organic matter. In order to study the effects of cow manure on cadmium availability and their interactions on common bean nodulation and growth parameters, an experiment was conducted under greenhouse conditions. The treatments included five cadmium levels (0, 2, 5, 10, 20 mg cadmium per kg soil) and four cow manure levels (0, 15, 30, 60 t ha-1) based on a completely randomized design with three replications. Results indicated that increased soil cadmium concentrations caused higher cadmium uptake by root tissues whereas, Root nodulation and total N content of shoot tissues decreased significantly at all cadmium concentration levels except for 2 mg Kg-1. In addition, the interaction of cow manure and high concentrations of cadmium caused a decrease in nodule number, nodule fresh weights and total N content of shoot in common bean.
Green waste compost with wood ash additive improves physico-chemical and biol...AI Publications
A greenhouse study was conducted to assess the potential of green waste wood ash compost on a tropical acid soil. Four types of compost (prepared with 0, 5, 10 and 15% of wood ash prior composting) were used to amend an Oxisol from the centre region of Cameroon. The different composts were mixed with the soil in 1/4 proportions (w/w); the experimental design was a completely randomized block with three replicates per treatment. The different treatments were planted with soybean (Glycine max L.) for three month growing period. Compost amendment increased the soil pH, organic carbon, total nitrogen and total phosphorus. Bacterial and fungal biomass together with cellulase and protease activities also increased in amended soil. Following soil chemical, physical and chemical parameters, plant growth and yield also improved in compost treated sols. However, compost prepared with 15% wood ash additive showed trends of inhibition of the soil microbiota. It can be concluded that green waste wood ash compost could be used as a suitable soil fertilizer for tropical acid soils, although precautions are to be taken when using these composts prepared with addition of wood ash ≥ 15%.
Bioremediating Effect of Glomus Hoi and Pseudomonas Aeruginosa on the Organic...IJEAB
This study analyzed the degrading effect of Glomus hoi and Pseudomonas aeruginosa on the organic content and heavy metals of oil refinery effluent polluted soil using Amaranthus cruentus as the test plant. This study was carried out to determine if agricultural activities can be improved using any or both of the micoorganisms. Eight different treatment layouts were used with three replicates for each level of pollution in the treatment layout. Ninety six (96) pots, each containing three kilograms of soil from both sterilized and unsterilized soil were used for the study. Fifty (50) grams of soil inoculum from propagated Arbuscular mycorrhiza was inoculated to a set of twenty four (24) experimental pots containing both sterilized and unsterilized soil before A. cruentus seedlings were transplanted to them. Another set of twenty four (24) pots containing both sterilized and unsterilized soil were injected with thirty (30) mL of P. aeruginosa inoculum solution before transplanting A. cruentus seedlings to them. The third set of twenty four (24) pots received dual inoculation of both fifty (50) grams of soil inoculum containing G. hoi and thirty (30) mL of P. aeruginosa inoculum solution before A. cruentus were transplanted to them. The residual twenty four (24) pots served as the control. Thereafter, pot preparation was arranged in the screenhouse in a randomized block design. The A. cruentus seedlings were raised in nursery for a period of two weeks before they were transplanted to the pots, seedlings were left for 3 days to overcome transplanting shock before contaminating the soil with refinery effluent at various concentrations of 0%, 2%, 4% and 6% v/w. The seedlings were allowed to grow for eight weeks before the termination of the experiment. The pre planting analysis of soil showed that heavy metals analyses (zinc and iron) of sterilized soil had a lower concentration to the unsterilized. The soil pH ranged from 6.3 to 6.8. It also revealed that organic matter and organic carbon content ranged from 0.8% to 1.3% and 0.4% to 1.7%. However, after the experiment, it was discovered in this study that treatments without any microorganism inoculation in sterilized and unsterilized soil had a higher level of % organic carbon and % organic matter content compared to the other treatments that were inoculated with one or two micro-organisms across all the levels of effluent concentration. Heavy metals of soil in all the soil samples were found to increase as the petrochemical effluent increased in concentration. The results obtained were analyzed using Duncan Multiple Range Test (DMRT) and other descriptive statistics. This study opined that the combined use of G. hoi and P. aeruginosa was more effective in improving the organic contentand the reduce heavy metals of oil refinery effluent polluted soil than when either is used singly.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Abstract :
Mulberry is cultivated by farmers for its leaves, the sole food for silkworm (Bombyx mori L.) for
commercial production of raw silk in Sericulture Industry. As mulberry is a perennial crop can be maintained
for several years in the field, selection of suitable land and follow-up of recommended package of practices are
inevitable for maintenance of potential productivity of the variety selected for cultivation. As the quality of
mulberry leaves alone contributes about 38.2% for the success of silkworm cocoon crop, quality linked leaf
productivity of mulberry leaves can be achieved through adequate supply of all required input into soil. Nitrogen
is one of the important macronutrient required for mulberry in larger quantity. In order to reduce the high cost
involved towards nitrogenous chemical fertilizers and to maintain the soil health in an eco-friendly way
Integrated Nutrient Management (INM) approach in agriculture sector became popular and the same has been
followed in mulberry cultivation as well in recent years. Use of different kinds of microbial inoculants as bio-
fertilizer to fix atmospheric nitrogen in mulberry garden brought improvements in soil health maintenance and
helps to reduce nitrogenous chemical fertilizer requirements and expenditure to farmers considerably without
affecting the quality linked productivity.
Keeping in view of the above an experiment study was conducted to ascertain the consistent efficacy of
Azotobacter chroococcum inoculants @ 108-9

obtained in
T1 and T2 respectively and quality of leaves on economic characters found without significant difference
between the treatments revealed the consistent efficiency of Azotobacter chroococcum in fixing atmospheric
nitrogen in the soil of mulberry garden to reduce nitrogenous chemical fertilizer and expenditure without
affecting the quality linked leaf productivity and mass culture of the bacteria for preparation of Nitrofert bio-
fertilizer, its application techniques are discussed in the paper.
Key Words : Mulberry leaf, bio-fertilizer, biological nitrogen fixation, eco-friendly soil health, potential

1. Introduction :
Mulberry is cultivated by farmers for its leaves, the sole food for silkworm (Bombyx mori L) for
commercial production of raw silk in Sericulture Industry. As mulberry is a perennial crop can be maintained
for many years, selection of land and follow-up of recommended package of practices are inevitable for quality
linked potential productivity throughout. Further the quality of mulberry leaves as single factor contributes
about 38.2% for the success of silkworm crop (Miyashita, 1986), adequate supply of all required input into soil
is very much essential. In India, during the Green Revolution period more emphasis was given for increase unit
area productivity of crops which facilitated in indiscriminate application of inorganic chemical fertilizers,
chemicals to control various pests and diseases without considering the soil health maintenance for long-term
use for agriculture purposes resulted in considerable damage to the soils of agriculture land. It was reported that
out of 235 mha of cultivable area, soils of 166 mha have been damaged (Swaminathan, 1994) in the country,
necessitated alternate methods to improve the soil health. Excessive uses of nitrate and phosphatic fertilizers
have led to extensive contamination of surface and ground waters (Dahama, 2003). To complete life cycle
normally, living organism requires a large numbers of substances from outside are called nutrition. Green plants
being autotrophic, requires only inorganic substances from outside (Pandey and Sinha, 1972). An essential
element is defined as one whose absence prevents plants from completing its life cycle or one that has clear

physiological role (Arnon and Stout, 1939). Though the atmosphere contains more than 70% of nitrogen, only
about 0.1% of fixed nitrogen is present in the soil and small traces of nitrogen from the atmosphere reach the
soil in a dissolved state in rain water (Rangaswami and Bagyaraj, 2004). The fate of nitrogen fertilizers in the
soil is controlled by several physical, chemical and biological factors. The percentage of recovery of nutrients
varies between the different types of fertilizers reported as 50-60; 5-15 and 75% of N P K respectively and
nitrogen deficiency is observed in plants grown on soils with low organic matter (< 0.4 % organic carbon) and
also reported that nearly 62 % soils are deficient in Nitrogen (Anonymous, 2011).
Nitrogen fixation is the reduction of N2 (atmospheric nitrogen) to NH3 (ammonia). Free living
prokaryotes with the ability to fix atmospheric dinitrogen (diazotrophs) are ubiquitous in soil. But our
knowledge of their ecological importance and their diversity remains incomplete. In natural ecosystems,
biological N2 fixation is most important source of N. The capacity for nitrogen fixation is widespread among
bacteria and archaea. The estimated contribution of free-living N-fixing prokaryotes to the N input of soil ranges
from 0-60 kg. ha-1
year-1
(Bűrgmann et al., 2003). Bio-fertilizers can make significant contribution towards the
development of strategies for productivity improvement which do not lead to an exponential rise in the
consumption of non-renewable forms of energy (Subba Rao, 1982) and the use of bio-fertilizers is currently
gaining interest as a cheap, safe alternative to chemical fertilizers (Sharma, 2002).
After isolation of two aerobic free living nitrogen fixing bacteria in 1901 by Martinus Beijerinck, and
named them as Azotobacter chroococcum and A. agile study on practical applicability of these Azotobacter spp.
attracted several workers. Yamagata and Itano (1923) reported that Azoto-bacter is ubiquitous in neutral and
weakly basic soils, but not in acidic soils and the growth of bacteria favored at a temperature of 20-30°
C and
Moreno et al., (1986) observed that in dry soils, Azotobacter can survive upto 24 years in the form of cysts. Use
of variety of carbohydrates, alcohols and salts of organic acids as sources of carbon and pH 4.8 to 8.5 found
optimum for growth of the bacteria George (2005).
Wong and Maier (1985) reported that hydrogen dependent mixotrophic growth of Azotobacter in a
nitrogen-free medium containing mannose and availability of hydrogen in the soil facilitates the growth of
Azotobacter in nature. Culture media inoculated with A. chrococcum with high NaCl concentration, incubated
on rotary shaker for 60 hours at 200 rpm facilitated full growth of colony and shown brown colour pigment. A.
chrococcum being a non-symbiotic bacteria have a great potential for use in production of bio-fertilizer due to
its ability to fix N2 (Nakade et al., (2012). Besides, nitrogen fixation, it also produces, Thiamin, Riboflavin,
IAA and gibberellins, when applied to seeds, seed germination is improved to a considerable extent and also
controls plant diseases due to the above substances (Kader et al., 2002).
Presence of ferredoxin, hydrogenase and an important enzyme nitrogenase required for nitrogen
fixation was reported by Shank et al., (2005) and of the different type of nitrogenase, the basic one is
Molybdenum- iron nitrogenase was reported by Howard and Rees (2006). Chen et al., (1995) observed that
Azotobacter spp. facilitate the mobility of heavy metals in the soil and thus enhance bioremediation of soil from
heavy metals, such as cadmium, mercury and lead. Emtiazia et al., (2004) reported that Azotobacter biodegrade
chlorine-containing aromatic compounds, such as 2,4,6-trichlorophenol which was used as an insecticide,
fungicide and herbicide till its mutagenic and carcinogenic effect was found (Li et al., 1991).
Like other agricultural crops, mulberry requires all sixteen nutrients and nitrogen in large quantity.
Based on the high cost involved in application of nitrogenous chemical fertilizers and to maintain the soil health
in an eco-friendly manner, Integrated Nutrient Management (INM) approach in agriculture sector became
popular in recent years, the same has been followed in mulberry cultivation as well.
A. chroococcum cells blended with peat soil/charcoal/FYM in powdered form as carrier material
containing 108-9
cells g-1
observed as optimum for application in mulberry garden. CSR&TI., Berhampore, India
has standardized the mass culture technique for production of a bio-fertilizer under the name “Nitrofert” to
reduce nitrogenous fertilizer requirement and expenditure in mulberry cultivation without affecting the quality
linked leaf productivity and for eco-friendly way of soil health improvement (Sudhakar et al., 2000). Mass
culture of A. chroococcum for production of nitrofert bio-fertilizer, findings of the experiment conducted on its
application and crop productivity in S1635 mulberry garden are discussed in detail in this paper.

2.2 Efficacy of Nitrofert on nitrogenous fertilizer saving and crop productivity in mulberry garden :
The experiment was carried out in Plot No. A-9 Agronomy Section of CSR&TI, Berhampore West
Bengal, India, well established irrigated mulberry garden raised in alluvial soil with S1635 high yielding variety
under Paired Row System with plant spacing of (150+90) x 60 cms the mulberry garden during July to
September 2012. After pruning of plants, 26 number of plots demarcated each with two paired rows and 10
plants and thus a total 40 number of plants per plot (Chaturvedi and Sarkar, 2000) in Completely Randomized
Design [CRD] as described by Sukhatme and Amble (1985) was drawn as experiment plan to accommodate 2
treatments with 13 replications each. In T1, recommended quantity of FYM @ 20 ton ha-1

split doses and chemical fertilizers NPK @ 336 : 180 : 112 kg. ha-1
year-1
in 5 equal split doses (Ray et al.,
1973) as control and in T2 FYM @ 20 ton ha-1
year-1
in two equal split doses and chemical fertilizers NPK @
168 : 180 : 112 kg. and Nitrofert 20 kgs ha-1
year-1
in 5 equal split doses (Plates : 11-16). Irrigation water
applied as and when required and all other package of practices recommended for mulberry garden maintenance
were followed uniformly in all plots. On 70th
day 5 randomly selected plants from each plot were pruned and
observations made on the following parameters individually and yield was estimated as suggested by Sreenivasa
Shetty et al., (1990).

3. Results And Discussion
3.1 Mass multiplication of Azotobacter chroococcum for Nitrofert bio-fertilizer production in laboratory :
From 10 litres of Azotobacter chroococcum bacteria media charcoal powder mixed 23 kgs of Nitrofert
bio-fertilizer with 108-9
cells g-1
carrier material prepared.
3.2 Efficacy of Nitrofert on nitrogenous fertilizer saving and crop productivity in mulberry garden :
Microbial inoculants in carrier based preparations containing beneficial microorganisms in a viable
state intended for seed or soil application and designed to improve soil fertility and help plant growth by
increasing the population and biological activity of desired microorganism in the root environment (Subba Rao,
1982). Inoculation of Azotobacter and AM fungus in mulberry has proved beneficial in terms of economizing N
and P fertilizer application by 50% without adverse effect on leaf yield and quality (Das et al, 1994).
Application of n-triacontanol (Vipul) as foliar spray and use of Azotobacter bio-fertilizer could increase the leaf
yield by 15-20% besides, 50% reduction in nitrogenous fertilizer (Rajanna et al, 2005).Azotobacter bio-fertilizer
application @ 20 kg ha-1
year-1
was able to curtail 50% nitrogenous fertilizer requirement of mulberry without
affecting yield and quality of leaves (Sudhakar et al, 2000). Similar results (Table 1 & Fig. 1-2) obtained in the
experiment conducted are discussed as below:
3.3 Number of branches / plant : An average of 15.92 and 13.92 number of branches recorded per plant in T2,
T1 respectively and the difference between the two treatments was statistically significant @ CD 5% level.
3.4 Branch height (cm) and total shoot length plant-1
(m) The difference in the average height of branches in
T1 and T2 recorded was statistically non significant @ CD 5% level the same was reflected in as well.
3.5 Number of leaves branch-1
and plant-1
: Though the difference in average number of leaves per branch
observed was statistically significant @ CD 5% level and the same per plant was non significant in T1 and
T2.

this crop in T1 and T2 respectively are on par statistically @ CD 5% level
3.12 Moisture Retention Capacity of leaf (%) : Average Moisture Retention Capacity of leaf of 94.00 and
94.94% recorded during this crop in T1 and T2 respectively are on par statistically @ CD 5% level.
4. Conclusion :
It may be concluded that the maintenance of A. chroococcum bacteria culture and mass multiplication
in Walkman’s culture medium under laboratory conditions for production of “Nitrofert” bio-fertilizer is
viable. “Nitrofert” bio-fertilizer application @ 20 kgs. ha-1
year-1
in 5 split doses in mulberry garden helps to
reduce upto 50% nitrogenous chemical fertilizer requirement and saves expenditure without affecting the quality
linked productivity, in addition it improves the soil health in an eco-friendly way.
