Abstract

A field experiment was conducted on Sesame (Sesamum indicum) at Research Farm of Agronomy, CCSHAU, Hisar during Kharif, 2022. The trial was conducted in a randomized block design with four levels of nitrogen and four levels of phosphorus and replicated thrice. The four nitrogen levels were: 0, 15, 30, and 45 kg ha-1, and the four phosphorus levels were 0, 15, 20, and 25 kg ha-1. Nitrogen @ 45 kg ha-1 and phosphorus @ 20 kg ha-1 resulted in the maximum significant growth, physiology, yield, and yield attributes of the crop compared to the control. Treatment with nitrogen application @ 45 kg ha-1 increased dry matter per plant at harvest, CCM, and seed yield by 43.5, 37.8, and 17.8 percent respectively compared to the control. Among treatments of phosphorus levels, phosphorus application @ 20 kg/ha improved dry matter, seed yield, and biological yield by 23.8, 24.4, and 27.5 percent compared to the control.

Conclusion

Nutrient management is crucial for the profuse growth and yield of a plant. The right proportion of different nutrients is important for the good performance of the cell’s biochemical and physiological functions. Nutrient requirements of a crop depend on whether the crop is grown rainfed or irrigated. Higher doses of nutrients than optimum result in detrimental effects on the growth of plants, thus reducing the yield and increasing the cost of cultivation. From the treatments of nitrogen and phosphorus levels in sesame grown under irrigated conditions, it can be concluded that nitrogen at the rate of 45 kg/ha and phosphorus @ 20 kg/ha was best to gain the highest yields.
