tailieunhanh - Growth, yield and economics of transplanted rice (Oryza sativa L.) as influenced by different weed management practices

Among the food crops, rice is the mainstay of the sustenance of Asia’s population since long. Therefore, smart rice research is needed to make the rice production systems economically and ecologically sustainable. Weeds are known to be a major biotic constraint in agricultural production systems. Of the total annual loss of agricultural produce from various pests in India, weeds accounts for 45%, insect 30%, diseases 20% and other pests 5% (Rao, 1983). In India, yield loss due to weeds in transplanted rice was estimated to the tune of % over weedy check (AICRP-weed management, 2003-2012). | Growth yield and economics of transplanted rice Oryza sativa L. as influenced by different weed management practices
