Improving Wheat productivity through Resource Conservation Techniques and Weed Management

RCT and Weed Management for wheat production

Abstract

Field experiment was conducted at Research Farm of T.D.P.G. College, Jaunpur (U.P.) during the rabi season of 2016-17 and 2017-18 to study the effect of resource conservation techniques (RCTs) and herbicides on weeds and yield of wheat. The relative density of P. hysterophorus  and C. didymus were higher under zero tillage condition while under conventional tillage higher density of  C. album and A. arvensis were recorded. The total weed density and  dry weight were significantly lower under conventional tillage as compare to zero tillage condition. The data of weed dynamics indicated that, weed density and weed dry weight of  broad leaf were decreased significantly with used herbicides as compared  to weedy check. However, the maximum  reduction of major broad  leaf weeds were noticed under halauxifen methyl at 12.76 g/ha treated plots which was statistically similar to application of metsulfuron methyl at 5g/ha in respect to control of broad leaf weeds. Significantly higher grain yield was recorded under conventional tillage as compared to zero tillage. The maximum grain yield (5 t/ha) was recorded with weed free environment, that was 43 per cent higher than weedy check. Among the various applied herbicides maximum grain yield was recorded under  metsulfuron methyl at 5g/ha treated plot which was very similar to application of  halauxifen methyl ester at 12.76 g/ha condition.
