Abstract

The study was carried out on sesame in North West of Pakistan. The experiment was laid out in RCBD having 3 replications. Four N and three S rates were applied in two splits one at sowing and second split with first irrigation. No of pods plant-1 and grain yield (kg ha-1) were affected significantly by N, S and control vs rest. No of grains pod-1 and 1000-seeds weight were affected significantly affected by nitrogen not sulfur. Mean values for nitrogen exhibited that highest grain yield (799.4) were obtained at 70 kg N ha-1 ,while minimum grain yield (637) were recorded at 0 kg N ha-1. Mean values for sulfur revealed that highest grain yield (807.1) were recorded at 30 kg S ha-1, while minimum grain yield (628.6) were recorded at 10 kg S ha-1. Nitrogen and sulfur interaction showed that optimum grain yield (1030 kg ha-1) was noted at 70:30 kg N:S ha-1, while minimum grain yield (516.10 kg ha-1) was noted at 150:10 kg N:S ha-1. It is concluded that nitrogen and sulfur applied at the rate of 70:30 kg N:S ha-1 perform better as compared to other treatment applied and thus recommended for attaining high yield.
