The experiment was carried out entitled “effect of interaction between nitrogen and sulphur on growth and yield of mustard (Brassica juncea L.)” at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), India, during Rabi (winter) season of 2021-22. The experiments were conducted in Factorial randomized block design which comprised of 25 treatment combinations in which five levels of Nitrogen (0,40,80,120 and 160 kg N ha-1) and five levels of sulphur (0,25,35,45 and 55 kg S ha-1). The experiments were laid out in the two factors RCBD with three replications, The plant height, number of branches plant-1, dry matter accumulation, seed and stover yield increased with increasing N level of 160 kg N ha-1 which was at par with 120 kg N ha-1 and while significantly superior over rest of the levels of nitrogen. On the other hand, with increasing S levels plant height, increased significantly up to 55 kg S ha-1. However, the number of branches plant-1 and seed yield and shoot yield increased up to the highest dose of S (55 kg S ha-1). Considering the combined effect of N and S, the treatment combination (120 kg n ha-1 and 45 kg S ha-1) produced the maximum seed yield (21.32 q ha-1).
