Effect of integrated weed management practices on growth of upland rice

Abstract

In the present experiment was carried out during Kharif season of 2016 at the Agronomy Farm, College of B.F.I.T, Suddhuwala, Dehradun to impact of integrated weed management practices on growth of upland rice. The experiment was laid out in randomized bock design was experiment with three replications and nine treatments. The growth of rice measured in terms of height, number of functional leaves, leaf area plant-1 and dry mater accumulation per plant was favorably influenced by weed free check and 20 and 40 DAS at two hand weedings. It was followed by application pre-emergence of butachlor 50% EC @ 1.25 kg a.i. per ha + hand wedding at 40 DAS. Similarly trend was observed in contributory character namely respect of yield, Number of panicles per m, sq.Number of grains per panicles, Grain weight per plant and 1000 grain weight i.e. test weight (g). Weed population at 60 DAS and at harvest to dry matter were significantly lower in weed free check followed by two hand weedings at 20 and 40 DAS, respectively.
