Disease management
Irrigation should be stopped 15 days before harvesting to check the growth and to enable the bulbs to become firm and compact.The crop will be ready for harvest when the leaves turn yellow. The tops also fall at this stage. After harvesting and field curing for drying of leaves, leaves are cut leaving 2.5cm at neck. An average crop can yield up-to 20,000kg per hectare (8,000kg/acre). A crop raised with care may yield up-to 35 to 45 tones/ha
