14. Effect of nitrogen and sulfur on yield and yield components of sesame (Sesamum indicum L.) in calcareous soil
Main Article Content
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.
