Harvesting and Yield
Fruits are harvested after three months of sowing. Harvesting can be done at weekly intervals. Harvesting of fruits can be done at immature stage and at mature stage. It is advisable to harvest fruits at immature stage for food consumption. If fruits are harvested at immature stage at frequent intervals application of Fertilisers in splits as top dressing is advised. Mature fruits are harvested for long distance transport requirements which takes time an for seed extraction. The matured fruits will have developed with full waxy coating on the surface. We can get more tonnage if we harvest fruits at immature stage than after maturity, since keeping fruits in the plant for long time will hinder further fruit formation. For seed purpose the fruits are left unharvested till all the veins and stalks are fully dried.
Ash gourd can be marketed through local markets or with an arrangement for marketing by a marketing agency. The fruits have be kept in good condition avoiding bruises and cuts during handling. It can be stored for long time without any damage to the fruits. This is advantageous to the farmer since he need not have to sell this urgently in distress. For seeds extraction also it has to be stored at least for 3 months and can be marketed.
