Abstract: A field experiment was conducted with the aim to know effects of different weed management on weed density, growth, yield and yield attributes of transplanted rice in typic ustochrept soil during rabi 2016-17 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U. P. (India). The experimental site was sandy loam in texture, low in organic carbon and available N, medium in available P and K and slightly alkaline in reaction. The experiment was laid out in randomized block design with three replications comprising eleven weed management treatments.
The results indicated that among the herbicides application of Sulphosulfuron + metsulfuron methyl @ 25+4 g a.i ha-1 significantly reduced the weed population and dry weight effectively over weedy check. The highest plant height, number of tillers m-2, dry matter accumulation, 1000-grain weight and grain yield (44.18 q ha-1) were recorded 42.96 per cent increase in grain yield over weedy check in barley crop with the application of Sulphosulfuron + metsulfuron methyl @ 25 + 4 g a.i ha-1.Therefore,which established its superiority over rest of the herbicides. The application of Sulphosulfuron + metsulfuron methyl @ 25 +4 g a.i ha-1 resulted in to higher gross return, net return and B: C ratio. Thus the application of Sulphosulfuron + metsulfuron methyl @ 25 + 4 g a.i ha-1 found better for sustainability of barley crop yield.
