Effect and techniques of using legumes as green nature for rice in the Mekong river Delta
Non-cash crop of green manure plants such as Azolla, Sesbania couldn’t apply for rice production. However, leguminous such as mung bean, soybean, cowpea, peanut for either cash crop or green manure are feasible for cultivation. Peanut and soybean were estimated as the best for rotation with rice crop, or for practicing intercrop with corn before rice. The following rice crop can increase rice yield by 20-30% or can decrease N requirement by 30-40 kg N/ha.
