The yam bean is grown principally from seed. It can be also grown from sprouted rootssaved from the previous crop. Traditionally yam bean is sown June-July with the onset of rainin North-Eastern India and is usually harvested in December-January. The time of sowing ofseed varies from June to September accordingly to the purpose of the crop. If it is for seedpurpose, sowing of seeds can be done in June-July. Late sowing discouraged the vegetativegrowth of the crop with less branching and flowering. Yam bean normally, flowers at 75 daysafter sowing. Removal of flowers results in better tuber yield and better quality. In case thereis scarcity of rains, irrigation is required. For September sown crop, it is advisable to givesupplementary irrigation so that the crop will not face moisture stress during tuberization.Yam bean is harvested after 130-140 days of sowing. The tubers are usually dugmanually. If harvesting is delayed, chances of cracking of tubers are more. Harvested tuberscan be stored for 2-3 days without any deterioration. They can be stored successfully for atleast 2 months at appropriate temperatures and can also be ‘field stored’, i.e. having the cropin the soil without removing top portion.
