Choosing the optimum time for transplanting is a most essential prerequisite for rice cultivation, to ensure proper and optimal growth of plants and increase the yield and to synchronize cultivation practices for irrigation and control of pest, diseases or rats. T. aman (transplanted aman) rice is planted under rain fed conditions during the monsoon season. In case of drought, t. aman rice cultivation suffers significant damages, which can cause increase in prices for staple food, and increase risk of seasonal food shortages. Therefore, timely transplantation is essential to secure higher production. Community participation and collective action in cultivating rice are especially important in areas regularly prone to natural hazards such as northwestern Bangladesh. This practice is designed to facilitate and promote community-based joint seedling production of t. aman rice. This is to ensure timely availability of seedlings to all community members for early transplantation, and thus contributing to timely growing of plants and increasing yields.
