Nutrients Spray for wheat grain size & yield (ਵੱਧ ਝਾੜ ਤੇ ਮੋਟੇ ਦਾਣੇ ਲਈ ਕਣਕ ਤੇ ਸਪਰੇਅ)Shergill Markhai

At boot or flag leaf stage of Wheat crop we can spray some nutrients in wheat crop for bold grains, good quality, disease resistacy and finally got higher yield. Some spray combinations are discussed in wheat for better yield. You can choose as per your soil and Crop requirements. all spray combination are not necessary. Dose of different spray chemicals per acre (4000square meter) are given below but combinations discussed in video.
Wheat crop (choose as per requirement)
NPK 0-52-34------ 1kg
Boron ------- 200 gm
NPK 13-0-45. -2kg Per 100 litre water
NPK 13-0-45 with other nutrients --- 1.250 - 1.5 kg
Manganese ---1 kg
Magnesium ---500 - 700gm
Urea ----- 9kg in 300 litre water
Chelated Zinc -- 100 - 150 gm

Don't mix all above chemicals, choose as per requirement of get guidelines from video.
Wheat grain size is strongly influenced by plant nutrition particularly during the important grain filling period. Nitrogen, phosphate, potassium, magnesium and zinc are particularly important.
Wheat grain size is determined by the plants genetics i.e. variety, and the length of the grain filling period. As soon as pollination has occurred the embryo and endosperm begin to develop with the plant redirecting photosynthates and also previously stored starch and protein (in leaves and stems) to these developing grains. The longer this period of grain fill is, the larger wheat grain size is likely to be.
Nitrogen management will have the most impact on final wheat grain size and weight. Applications made early will ensure a canopy that is large, containing high levels of stem carbohydrate that is translocated to the developing grain during maturation
Phosphate has a major role in the supply of energy for plant processes. Redistribution of stored carbohydrate requires energy making phosphate nutrition important in achieving good wheat grain size.
Potassium aids movement of nutrients around the plant as it regulates the transpiration flows as the wheat plant redistributes minerals to the ear potassium levels need to be maintained.
Potassium will also help avoid early senescence often brought on by drought during grain fill. Potassium deficient plants are poor at regulating transpiration through the leaf leading to heat stress and wilting. Adequate potassium supplies will extend the grain filling period leading to improvements in wheat grain weight.
Both manganese and zinc with their roles in nitrogen metabolism by the plant will improve wheat grain weight.
Besides nutrient management, the grain size can be influenced by water management (irrigation to avoid drought stress), as well as disease management – use fungicides and nutrients to maintain green leaf area and reduce disease incidence improving plant health
Both solid fertiliser phosphate and foliar phosphate can be used to improve final grain size.
