RESPONSE OF INDIAN MUSTARD (BRASSICA-JUNCEA) TO DIFFERENT IRRIGATION SCHEDULES, AND NITROGEN AND SULFUR LEVELS

An experiment was conducted during 1986-87 and 1987-88 to study the effect 3 irrigation schedules, and 3 levels each of nitrogen and sulphur on Indian mustard [Brassica juncea (L.) Czernj. & Cosson]. Irrigation at 75 mm cumulative pan evaporation (CPE) and at 100 mm CPE were at par and significantly superior to irrigation given at 150 mm CPE in affecting the branches and pods/plant, pod length, grains/pod, 1,000-grain weight, seed and stover yields, oil yield/ha and net income/ha. Each successive increase in the level of N from 0 to 80 kg/ha significantly increased the growth characters, yield attributes, seed and stover yields and net income/ha. The growth characters, yield attributes, seed and stover yields and net income/ha increased significantly with each successive increase in the level of S.
