Abstract:
A field experiment was conducted on sandy loam soil during 2015-16 and 2016-17 at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.). The treatments comprised five levels of nutrients viz.; 100% NPK, 75% N-PK + 25% N through FYM, 75% N-PK + 25% N through vermicompost, 50% N-PK + 50% N through FYM, 50% N-PK + 50% N through vermicompost as main plot and four levels of weed control measures viz; Control, Two hand weeding, Trisulfuron 15g a.i. ha-1 and Carfentrazone ethyl 15g a.i. ha-1 as sub plot and it was laid out in split-plot design with three replications. The results indicated that among different nutrient management practices, the maximum NPK uptake in barley and weeds were recorded with the treatment 75% N-PK + 25% N through vermicompost over rest of the other treatments. Among weed management practices, NPK content and uptake were recorded highest in two hand weeding followed by Trisulfuron 15g a.i. ha-1 and control. Therefore, nutrient uptake by crop, status of the soil also improved with the integration of organic and inorganic sources of plant nutrients. Thus 75% NPK + 25% N through vermicompost with Trisulfuron 15g a.i. ha-1 may be recommended for better weed control and higher barley yield.
