Optimum irrigation schedule and rates of nitrogen, phosphorus and sulphur for high seed yield of toria

摘要

Short duration of toria makes it suitable for multiple cropping system, allowing 300% intensity of cropping. In Punjab, toria is grown as a catch crop after rice, maize or rainy-season pulse crops. One of the.reasons for low yield of toria is the lackof appropriate information on its water-nutrient management. Balanced nutrients and water supply are crucial for optimizing the growth of this crop. The authors suggest that for getting high seed yield under Punjab conditions, the crop may be fertilized at 120 kg N, 17.5 kg P and 50 kg S/ha along with 2 irrigations — one at about 3-4 weeks and the other at about 9-10 weeks stage.
