Mostly rainfed; irrigate weekly when the monsoon fails. Waterlogging harms the crop. Mulch right after planting to save moisture, moderate soil temperature and suppress weeds. FYM 25 t/ha at the last ploughing; NPK 80:60:100 kg/ha in total — 40:60:50 at 45 days with weeding, then N 40 and K 50 a month later.
