How to fertilize sesame

Sesame is a crop that requires more fertilizer. For every 100 kg of seed produced, 9 kg of nitrogen, 2 kg of phosphoric acid and 9 kg of potassium oxide are required. Applying the base fertilizer, applying the seed fertilizer, staging the fertilizer in stages, and increasing the potassium fertilizer in a timely manner is an effective measure to increase the yield of sesame. The base fertilizer should be based on organic fertilizer. The distribution of sesame root layer is shallow, and the effect of shallow application of base fertilizer is good.
Generally, 5-8 kilograms of cake fertilizer is applied to the acre, or 3-4 kilograms of sulfuric acid or 300-400 kilograms of soil fertilizer. Sesame should be topdressed in the seedling, bud and full bloom periods, and the yield increase effect is obvious. Top dressing before flowering can fully meet the nutrient needs of vegetative growth and reproductive growth. Spraying phosphorus and potassium fertilizer during flowering can increase the weight and increase the grain weight and increase the oil content. It is usually sprayed with a 0.4% solution of potassium dihydrogen phosphate in fine weather. Spray once every 5-6 days, even spray 2-3 times, each time 50-60 kg of fertilizer. After spraying, it should be re-sprayed in case of rain.
