Pre sowing seed treatment in maize
Maize occupies second position after rice in Nepal.It is a main staple food crop of more than 55% of the people of Nepal.It can be used as cattle feed and fodder also. Depending upon the altitude it is grown during winter, summer and rainy season.Although the major area is under rainy season crop and the productivity is higher in winter season crop. More than 80% of the maize is grown in hills (70% in mid hill and 10% in high hill) and about 20% in terai and inner terai region of Nepal.
The slides describing about the different techniques of seed production, as the seed is the basic part of any production program. Therefore, please provide review about these techniques.
For the determination of Ca+ Mg both together, the versenate titration method is most popularly used in which EDTA (Ethelyne diamine tetra acetic acid) disodium salt solution is used to chelate them.
The two cations can also be precisely estimated in water sample using atomic absorption spectrophotometer (AAS) but for all practical purposes versenate titration method is good enough.
Calcium alone can also be estimated by versenate method using ammonium purpurate (murexide) indicator and thus Mg can be obtained by deduction of Ca from Ca+Mg content.
Calcium estimation can be done on flame photometer also but the precision is not very high. The formation of Ca and Mg complexes is at pH 10 is achieved by using ammonium hydroxide-ammonium chloride buffer.
Presence of high percentage of exchangeable sodium in soils produced alkali conditions- high pH and poor soil structure. Reclamation of such soils involves the use of gypsum in the form of powder. A useful and rough measure of exchangeable Ca (plus Mg) in soils and the amounts of gypsum required to replace the sodium as an initial step in soil reclamation consists of adding a given amount of saturated solution of gypsum to a weighed amount of soil and by versenate titration, determining the combined Ca and Mg left in solution at equilibrium. The amount of Ca adsorbed by the soil (initial Ca in solution – Ca +Mg in solution after equilibration with soil) is a measure of the gypsum requirement of the soil.
Carbonate and bicarbonate ions in the sample can be determined by titrating it with against standard sulphuric acid (H2SO4) using phenolphthalein and methyl orange as indicators.
Potassium in solution is atomized to flame and the flame excites atom of potassium causing them to emit radiation at specific wavelength. The amount of radiation emitted is directly proportional to concentration of the solution and it is measured in a flame photometer with suitable filter, which transmits only potassium wavelength (768 nm red filter).
Organic carbon in organic matter is oxidized by known but excess of chromic acid. The excess chromic acid not reduced by organic matter is determined by back titration with standard ferrous sulphate solution, using diphenylamine or ferroin indicator. The organic carbon content in soil is calculated from the chromic acid utilized (reduced) by it.
Determination of soil available nitrogen by Alkaline
permanganate method (Subbiah and Asija, 1956).
Nitrogen is necessary for all forms of life. It is most important
essential plant nutrient for crop production as it is constituted the building blocks of almost all the plant structures.
This ppt is about the distribution of wasteland and problem soils. Those lands are wastelands which are ecologically unstable,
whose topsoil has nearly been completely lost, and
which have developed toxicity in the root zones or growth of most plants, both annual crops and trees”.
Sulfur is a chemical element with symbol S and atomic number 16 with atomic mass 32.065.
It is abundant, multivalent, brittle, yellow, tasteless, odourless and non-metallic element.
Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth.
In the Bible, sulfur is called brimstone .
Today, almost all elemental sulfur is produced as a by product of removing sulfur-containing contaminants from natural gas and petroleum.
Most soil sources of S are in the organic matter and therefore concentrated in the top soil or low layer.
Under normal conditions, sulfur atom forms cyclic octatomic molecules with a chemical formula S8.
Sulphur is the most abundent and widely distributed element in the nature and found both in free as well as combined states.
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.
The development of Plant Nutrient Management to increase the quantity of plant nutrients in farming systems and thus crop productivity is a major challenge for food security and rural development.The depletion of nutrient stocks in the soil is a major but often hidden form of land degradation. On the other hand, excessive application of nutrients or inefficient management means an economic loss to the farmer and can cause environmental problems, especially if large quantities of nutrients are lost from the soil-plant system into water or air.
Increasing agricultural production by improving plant nutrition management, together with a better use of other production factors is thus a complex challenge. Nutrient management implies managing all nutrient sources - fertilisers, organic manures, waste materials suitable for recycling nutrients, soil reserves, biological nitrogen fixation (BNF) and bio-fertilizers in such a way that yield is not knowingly increased while every effort is made to minimise losses of nutrients to environment
Plant need water, air, light, suitable temperature and 17 essential nutrients for growth and development in the right combination. When plant suffers from malnutrition, exhibits symptoms of being unhealthy reliable nutrient recommendations are dependent upon accurate soil tests and crop nutrient calibrations based on extensive field research. An important part of crop production is being able to identify and prevent plant nutrient deficiencies. Optimization of pistachio productivity and quality requires an understanding of the nutrient requirements of the tree, the factors that influence nutrient availability and the methods used to diagnose and correct deficiencies. Several methods for nutritional diagnosis using leaf tissue analysis have been proposed and used, including the critical value (CV), the sufficiency range approach (SRA), and the diagnosis and recommendation integrated system (DRIS). de both soil and tissues analysis. Renewed and intensified efforts are in progress to identify nutrient constraints using latest diagnostic tools and managing them more precisely through intervention of geospatial technologies (GPS, GIS etc.). There have been consistent concerns about the relegated fertilizer use efficiency, warranting further the revision of ongoing practices, and adoption of some alternative strategies. Diagnosis of nutrient constraints and their effective management has, therefore, now shifted in favour of INM.
Indian agriculture feels the pain of fatigue of green revolution.
In the past 50 years, the fertilizer consumption exponentially increased from 0.5 (1960’s) to 24 million tonnes (2013) that commensurate with four-fold increase in food grain output (254 million tonnes) In order to achieve a target of 300 million tonnes of food grains and to feed the burgeoning population of 1.4 billion in 2025, the country will require 45 million tonnes of nutrients as against a current consumption level of 23 million tonnes. The sustainable agriculture and precision farming both are the urgent issues and hence the suitable agro-technological interventions are essential (e.g., nano and biotechnology) for ensuring the safety and sustainability of relevant production system.
Indian agriculture is passing through difficult times due to erractic weather conditions, especially drought and excessive rainfall, there by resulting into wide spread distress among farmers.
The average income of an agricultural household during July 2012 to June 2013 was as low as Rs.6,426.
As many as 22.50% of the farmers live below poverty line, the country also witnessed a sharp increase in the number of farmers suicides due to losses from farming and low farm income.
Farming in India is becoming hard and unsuccessful due to several causes like unexpected rainfalls,droughts, increased cost of cultivation due to pests and diseases, decrease in productivity of land, unavailability of water etc..
Farmers get very low income for their produce due to prevailing market prices that are very unstable.
Decline in Agriculture productivity and Income has a serious effect on rural house holds, and other economic, social as well as sustainability indicators.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The Indian economy is classified into different sectors to simplify the analysis and understanding of economic activities. For Class 10, it's essential to grasp the sectors of the Indian economy, understand their characteristics, and recognize their importance. This guide will provide detailed notes on the Sectors of the Indian Economy Class 10, using specific long-tail keywords to enhance comprehension.

3. Sorghum ( Open pollinated varieties )
Botanical name – Sorghum bicolor
Family- Gramineae
Origin-Tropical & Subtropical region of Africa & Asia
Sorghum is used for grain, fiber&fodder.
One of the most important staple food for million poor rural
people.
Sorghum is about 70% starch ,so is good energy source.It’s starch
consist of 70 to 80 % amylopectin.
In rank first sorghum production by country U.S. (10,988.00 MT)
in world & India in rank fifth(5,000,00 MT) in world.
4. Land selected for sorghum seed production should have good
drainage facility so as to avoid water stagnation.
Previous crop in the land should not be of any other variety of
sorghum.
Land should be used sandy loam & well drained soil.
5. Sorghum is an often crops pollinated crop having 50% cross
pollination. Isolation distance should be maintained so as to
avoid varietal contamination of seed.
Isolation distance is the distance by which the seed crop is
separated from any other variety of the same crop.
Contaminants Isolation Distance (M)

Certified seed
Other varieties 200 100
Sudan grass 400 400
Fodder sorghum 400 400
6. Though sorghum is grown as rain fed as well as irrigated
crop in different seasons, appropriate season to produce good
quality seeds is important.
For quality seed production, dry and cool weather is more
favourable than hot and humid weather during panicle
emergence and seed development stage.
For seed production, sowing may be done during June – July
and October – November seasons. Of these, October -
November is more conductive for quality seed production.
7. Seeds are soaked in 2% potassium dehydrogenase phosphate
solution for 10 hours and then dried back to original moisture
One kg of seeds are to be soaked in 600 ml of leaf extract for 16
hours. Hardened seeds will have the ability to withstand drought
during germination and plant growth.
8. Good quality seeds should be used to maintain the required crop
stand.
For of land, 12 to15 kg of seed is required. For certified seed
production, foundation seed should be sown.
Seeds with low germination will also be less vigorous and hence
crop growth is very much reduced. Seeds affected by sugary
diseases should be removed.
9. After the basal application of above fertilizers, ridges of six
metre length are formed at 45 cm distance.
Seeds are sown with a spacing of 15 cm on one side of the
ridge
After the application of 12.5 tonnes of FYM, plough the field
1 to 2 times by harrowing 2 to 3 times&levelling.
Then apply 2 kg of Azospirillum uniformly.
10. Micronutrient
For zinc deficient and iron deficient soils, 25 kg of ZnSO4 and 50
kg of FeSO4 have to be applied respectively

After furrow formation, fertilizer should be applied uniformly in the
furrow.
11. According to the soil condition, irrigation is given once in 7 days or once in
10 days. The following are the important stages in which drought should be
avoided.
Panicle emergence stage Flowering stage Seed maturation stage
12. a) Weed Management:
Hoeing and Weeding is necessary for controlling of weed.
Weed are also controlled by spraying of 1kg Atrazine(in 700lit of
water)ha after 2-3 day of sowing.
b) Disease Control:
Disease plant should be control Sugary disease of jawor.
Spraying of 0.2% Zineb should be spray after 45 days of sowing.
C) Insect control:
15 kg Thimet ha should be apply in furrow with fertilizer (not with seed)
at time of sowing for contolled Shoot fly .One spray 1.5 kg Thidon/ha
(in 700lit water) should be at 10 to 15 days after germination for
controlling Stem borer.
13. Growth stages Off-types
Before flowering
Self sown crop plants with different leaf colour, shape and
stem colour
During flowering
Early or late flowering plants and plants with deviant panicle
shape
Before harvest
Panicle affects by ergot, fungi and smut and plants with
deviating panicle features
14. Sorghum crop should be harvested from 40-45 days after 50%
flowering.
At this stage, moisture content will be around 20-22 per cent,
seeds will have black layer at the basal portion.
Seed weight, germination and vigour would also be high. The
seeds harvested before harvestable maturity are immature and
will shrink upon drying.
15. The harvested ear heads should be dried to bring down the seed
moisture content to 15-18 per cent.
If the seed moisture is below 15% then, seed injury may occur cracking
and above 18% moisture then will be occurrence of crushing injuries.
These mechanical injuries may affect the germination and vigour of the
seed besides paying way for fungal infection.
Seed are dried in sunshine heat.
Harvested Seeds are to be dried to a moisture content of 10-12 per can
Seed yield of 2000 kg/ ha can be harvested.
16. Seed processing is an operation by which all immature, wrinkled,
broken and small seeds as well as all physical impurities such as
sand, stones, dust, other crop sees and week seeds are removed.
For processing sorghum seeds, sieve of 9/64" diameter can be
used so as to get uniform size seeds.
17. SEED TREATMENT:
Seed treat to use a safe and non-poisonous chemicals
like Halogen mixture is recommended for treating
sorghum seeds @ 3 g /kg of seeds.
Halogen mixture can be prepared by mixing
bleaching power (calcium oxy-chloride) + calcium
carbonate + agape leaf powder (Albizzia amara)
5:4:1 proportion respectively.
18. Always, new bags have to be used for packing the
seeds.
Seeds are hygoroscopic in nature which means
they have the tendency to absorb moisture from the
atmosphere
, seeds stored in cloth or gunny bags, loose
viability fast. In such places, moisture vapour proof
containers like polythene (700 guage thickness)
bags can be used.
Storage godown has to be thoroughly cleaned before storing seeds
19. Seed Moisture should be lowered below 8%, when the seeds
are stored in moisture vapour poof container.
Direct contact of seed bags with the floor or wall is to be
avoided.
Seed bags should be stacked above the wooden pallet.
While stacking, number of bags per row should not exceed 8,
otherwise seeds in the lower bag will deteriorate due to
pressure
20. Seed certification guarantees the quality of seed as it ensures that the
certified seed.
genetic, physical, physiological and seed health qualities.
It starts from verifying whether seeds were obtained from authenticated
source, verification of isolation distance and inspection during plant
growth, flowering, harvesting, processing and bagging.
21. seed sample sent to seed testing lab to test physical purity
and germination.
Then certification tag is issued. Colour of the tag is blue
