Climate change effect on abiotic stress in fruit crops Parshant Bakshi
A change of climate, which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods.
Global climate change and increasing climatic variability are recently considered a huge concern worldwide due to enormous emissions of greenhouse gases to the atmosphere and its more apparent effect on fruit crops because of its perennial nature. The changed climatic parameters affect the crop physiology, biochemistry, floral biology, biotic stresses like disease-pest incidence, etc., and ultimately resulted to the reduction of yield and quality of fruit crops. So, it is big challenge to the scientists of the world.
Diagnosis and Recommendation Integrated System is a new approach to interpreting leaf or plant analysis and a comprehensive system which identifies all the nutritional factors limiting crop production and increases the chances of obtaining high crop yields by improving fertilizer recommendations.
Management Practices for Improving Water Use Efficiency.pptxanju bala
Water use efficiency
Production (of crops) per unit of water applied.
Expressed in kg/ha-mm.
Two distinct terms are used in expressing water use efficiency:
Crop water use efficiency: It is the ratio of crop yield (Y) to the amount of water depleted by the crop in the process of evapotranspiration (ET).
Crop WUE = Y/ET
Field water use efficiency: It is the ratio of crop yield (Y) to the total amount of water used in the field (WR), which include ET, deep percolation and that used in plant metabolic processes.
Field WUE = Y/WR

Significance of agronomic biofortification with zinc in maize.pptxrangaswamyranga8341
Fortification is a cost-effective and sustainable approach, which is highly effective and has large coverage, especially in the poorer regions of the world.
Fortification with the help of fertilizers would be a very rapid and practical approach to maximize mineral uptake and grain mineral accumulation in food crops immediately.
Most of the Indian soils are deficient in micro, macronutrients, and organic matter, by following the fortification approach we can reduce Nutrient deficiency in soils. Organic matter is the best source for the enrichment of micronutrients, and biofertilizers and also releases nutrients slowly into soil for a long period during crop growth.
About 75% of exogenous applications of Zn sources like ZnSO4 get fixed in the soil.
Fixation of Zn in soils with pH > 7.0 increases with increasing concentration of carbonates, thus becoming unavailable and can be reverted to available form with Zn solubilizing bacteria through the production of organic acids viz., gluconic acid which is designated as a strong acid among the mono carboxylic group of acid and are found to be easily biodegradable. Gluconic acid has the major anion which may be an important agent that helps in the solubilization of insoluble Zn compounds and makes it available to plant roots.
— Field experiment was conducted to study the impact of sulfur (S) and boron (B) on yield and yield component of broccoli. Sulfur was applied @ 0 (control), 20 and 40 kg ha-1 as elemental sulfur while B was applied at the rate 0, 1 and 1.5 kg ha-1 as borax along with a basal dose of N,P and K @ 120, 90 and 60 kg ha-1. All the fertilizers were applied at the time of sowing. The experimental design used was randomized complete block design (RCBD) with three replications. The data on plant height, number of leaves, flower diameter, head yield and biological mass were recorded along with S and B concentration in soil after crop harvesting. The result revealed that yield and yield parameter increased with increasing levels of S and B with higher head yield, flower diameter and plant height were observed when 40 kg ha-1 S and 1.5 kg ha-1 B were applied. It was further noted that head yield and head diameter were non-significant when averaged across the B treatment between 20 and 40 kg ha-1 applied S but significant from control. Similarly, when the yield parameters were average across the S treatment, there was a significant and linear increase with higher B level. Soil analysis showed that both B an S concentration in soil increased by increasing level of applied S and B. So the optimum level of S and B for broccoli was 40 and 1.5 kg ha-1 respectively for higher yield of broccoli.

Effects of salinity stress on growth, Water use efficiency and biomass partit...Innspub Net
Future crop production is predicted to face significant challenges from salinity stress due to secondary salinization. Therefore future-proofing crop production in these conditions is an essential path towards addressing food security. We evaluated the effect of irrigation with water of 0, 4 and 8 ppt salinity on growth, biomass partitioning, WUE and chlorophyll fluorescence of Vernonia hymenolepis A.Rich as ameliorated by fertilization with three levels of NPK20:10:10. Data were analysed for variance using the General Linear Model ANOVA procedure, after positive tests for normality and homogeneity of variance. Means were separated through the Dunnett test. Pearson Correlation was done to determine relationship between variables and these were spatially projected using the Factor Analysis procedure, without rotation. Under fertilization at 8 g NPK20:10:10 per plant, growth was stimulated by salinity increase to 4 ppt (35.43cm) compared to 30.43cm for control plants. Fertilizer application significantly improved all the biomass fractions of plants irrigated with water of 4 ppt relative to the control, while root:shoot ratios were highest for unfertilized plants indicating resource re-allocation to roots for better foraging. Chlorophyll fluorescence ranged between 0.716 and 0.727 and did not differ significantly across treatments. These values indicate that all treatments were under stress, including control plants. Values of WUE and RGR indicate that fertilization of plants irrigated with water of 4ppt salinity enhances growth and Harvest Index of V. hymenolepis, in spite of the registered stress. This is significant to future food security.
Physiological Quality of Bean Seeds Related To Azotobacter spp. InoculationIOSRJAVS
Research aimed at improving the quality of crops. The results obtained with seed coating were very influential with regard to fertilization and disease resistance. Nitrogen fertilization increases costs in agricultural production and the loss of fertile lands, altering the natural conditions and has negative consequences for the microorganisms (MO), which regulate the balance between quality of crops and soils. The biological nitrogen fixation (BNF) consists on MO work which provide nitrogen in soil and secrete substances that promote plant growth, these can be made by inoculation of seeds. The germination rate, emergency and vigor are an indicator that determines the productivity and physiological quality of a plant variety. The germination rate, number of emerged seeds per pot in favorable field conditions and vigor by accelerated aging test were evaluated. The seed treatments were: the seed inoculation with Azotobacter spp., Immersion in nutrient broth without bacteria, sterilization and zero handling. The experiment has shown that inoculation of common bean seeds with Azotobacter spp. does not adversely affect germination, emergency or vigor and stimulate the development of abnormal seedlings.
Bio-fertilizers are being essential component of organic farming are the preparations containing live or latent cells of efficient strains of nitrogen fixing, phosphate solubilizing or cellulolytic micro-organisms used for application to seed, soil or composting areas with the objective of increasing number of such micro-organisms and accelerate those microbial processes which augment the availability of nutrients that can be easily assimilated by plants. Biofertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, solubilise insoluble soil phosphates and produces plant growth substances in the soil.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Deficiency of B is known as “hard fruit,” since the fruit is hard and dry due to lumps in the rind making happen by gum impregnations.
The main fruit signs contain premature shedding of young fruits. Such fruits have brownish discolorations in the white
zone of the rind (albedo), which are defined as gum pockets or impregnations of the tissue with gum and abnormally
thick albedo.

The main driving force in Zn2+ uptake (cation uptake) is the hyperpolarization of RCPM which is mediated through activity of RCPM H+-ATPase system. The RCPM H+-ATPase system actively pumps. H + ion extracellularly at the expense of ATP hydrolysis. Release of H? ion in rhizosphere causes hyperpolarization of RCPM on one hand while reduces the soil pH on the other hand which results in increased cation uptake rate.

Treatment effects were statistically significant (Table 2): spring foliar application of Mn reduced leaf drop and the number of blotched leaves. The influence might be due to increased levels of Mn in the leaf. Also greenness and leaf N concentrations were positively affected by spring application. Mn foliar spring application in contrast to the other treatments was effective in reducing leaf drop incidence and number of blotched leaves as the growing season advanced.
Mn nutrition was also affected by rootstock: M26 showed the highest values of leaf Mn concentrations,
whilst M11 had the lowest.
