How to fertilize sesame for high yields? Detailed fertilization methods
How to fertilize sesame for high yields? Please provide guidance on the nutrient requirements of high-yielding sesame. Sesame is a fertilizer-loving crop; for every 100 kg of seed produced, it needs to absorb 8-9 kg of pure nitrogen, 3 kg of phosphorus pentoxide, and 7 kg of potassium oxide. At present, sesame yields are generally 40-60 kg per mu, while high-yielding fields generally reach 75-95 kg...

How to fertilize sesame for good results when planting it?
How should sesame be fertilized when planting? Please give guidance. For fertilizing sesame, you can refer to the following methods: Apply seedling fertilizer early. Because sesame seeds are relatively small, and because too much nitrogen fertilizer is often applied as a base fertilizer, the seedlings are prone to excessive vegetative growth and become leggy seedlings. Therefore, for sesame, in combination with early thinning and early final thinning of seedlings, apply a quick-acting fertilizer once early according to seedling condition. Applying seedling fertilizer well is an important measure for sesame to start growing early and grow vigorously. For seedling-stage fertilizer, diluted decomposed human manure or urea is preferable. Generally, after final thinning, apply 2-3 kg of urea per mu as a topdressing. When drought is severe, first relieve the drought and then apply the topdressing, or dilute it with thin human manure and pour it on. For those with weaker seedling vigor, the "special meal" method should also be used to apply a seedling-promoting fertilizer. When applying seedling fertilizer to sesame, also according to the characteristic that sesame has a relatively shallow root system, apply it as shallowly as possible or concentrate it near the roots.
