Abstract :
Agro-climatic conditions and soils of Pakistan are quite conducive for the sesame crop production. However, area allocated and average production is still far below than the other countries of the world. One of the reasons of its low productivity in Pakistan is the low, inadequate and improper fertilizers management. Among the various factors influencing crop production, phosphorus (P) and sulphur (S) boost its yield and quality. A field trial was conducted in summer 2012 using phosphorus @ of 0, 25, 50 and 75 kg ha^‑1 and sulphur @ of 0, 15, 30 and 45 kg ha^‑1, respectively on the yield contributing parameters of sesame. Pods plant^‑1, grain yield, plant height, and harvest index (HI) were observed highest using P @ 50 kg ha^-1, while flowering and maturity were delayed when no P and S applied. Pods plant^-1and biological yield were recorded highest at sulphur level 45 kg ha^-1. The HI attained its peak at 75 kg P ha^-1 with no sulphur application. It was concluded that solicitation of phosphorus and sulphur @ 50 kg ha6-1 and 45 kg ha^-1, respectively resulted in significantly higher yield contributing parameters of sesame; therefore, recommended for the locality.
