Abstract: The experiment was conducted to study the effect of nitrogen and sulphur on the growth and yield of French bean. The experiment consisted of two factors namely; (i) Nitrogen level viz. N₀ (no nitrogen), N₁ (60 kg N/ha), N₂ (90 kg N/ha), N₃ (120 kg N/ha) and N₄ (150 kg N/ha) and (ii) Sulphur level viz. S₀ (no Sulphur), S₁ (10 kg S/ha), S₂ (15 kg S/ha) and S₃ (20 kg S/ha). The experiment was laid out in randomized complete block design with three replications. The highest grain yield (1.78 t ha^-1) and (1.480 t ha^-1) were observed from 120 kg N ha^-1 (N₃) and 10 kg S ha^-1 (S₁), respectively. On the other hand, lowest grain yield (1.212 t ha^-1) and (1.332 t ha^-1) were found from 0 kg N ha^-1 (N₀) and 20 kg S ha^-1 (S₃), respectively. Considering the interaction it was found that the yield contributing characters and yield of French bean varieties were increased with the good combination of nitrogen and sulphur doses. The highest grain yield (1.97 t ha^-1) was observed from 120 kg N ha^-1 × 10 kg S ha^-1 (N₃S₁), whereas lowest grain yield (0.97 t ha^-1) was found from 0 kg N ha^-1 × 15 kg S ha^-1. Hence, the nitrogen and sulphur fertilizer management is very important agronomic management practices for higher and efficient production of French bean.
