The quality of seed to a great extent depends on the appropriate stage of the fruits at the time of harvest. Hence it becomes crucial to underline the optimum stage of harvesting the fruits for seed purpose. It has also been observed that if the harvested fruits of gourd crops are kept for some time before the extraction, it further improves the quality of seeds. It thus becomes important to specify the post harvest period (after ripening) also till seed extraction for improvement in the seed quality. The present investigation was conducted in a factorial RBD with three replications to study...
