Yield

Yield
    With good management, grain yield of 3.0-5.0 t/ha and straw yield of 5.0-5.5 t/ha can be obtained depending on varieties, season, locality and method of cultivation. Hybrids can yield up to 6.0-8.5 t/ha.

    Cropping System
    Mixed cropping
    1. Rice + Rice: Growing two rice varieties together differing in plant height and growth duration in alternate lines.
    2. Rice + non rice crop:Non rice crop like green gram, sesame, black gram, jute, maize, forage sorghum etc. Both the crops are sown in March-April and the inter crop is harvested before the advent of flooding in June. In case of green gram, only the pods are picked and the remaining portion provides nutrition to rice plant after decomposition.
    3. Rice + Azolla: Azolla is grown along with rice as green manure crop. After incorporation it supplies nitrogen to rice crop.
    4. Rice + Fish/Prawn culture: Integration of aquaculture with rice faring in flooded rice augments farm output and income and also benefits rice by improving its environments.

    This system has been found to be economically beneficial, besides reducing the stem borer infestation and working as predator of several pests of rice. Many fish species like catfish, snake head, Anabas sp. and Trichogaster sp. are adapted to swamp conditions.
