Mostly rainfed; sprinkler irrigation in summer increases yield. Compost 25 t/ha and NPK 75:75:150 kg/ha in two splits (June–July and October–November). Keep shade at 40–50% for rainfed and 55–60% for irrigated crops with a mix of medium-sized shade trees. At the end of the monsoon, lightly rake and mulch around plants (about 75 cm radius) to save moisture for the dry season.
