Barley is the most important food grain crop among cereals and stands next only to rice in our country. It has significantly contributed in the success of the green revolution and has greatly helped to transform our country from a situation of ship to mouth to being setsufficient. Barley is a good supplement for nutritional requirement of human body as it contains 8-10% protein and carbohydrates, fat, crude fiber. A field experiment was conducted during 2015-16 and 2016-17at Crop Research Center, Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (.). The experiment was laid out in split-plot design with three replications. The rabi season experiment comprised of five levels of nutrient 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 and four levels of weed control measures viz., Control, Two hand weeding, Trisulfuron 15g ha-1 and Carfentrazone ethyl 15g ha-1 . The plant height was significantly affected at 30, 60, 90 DAS and at harvest in different treatments. The maximum plant height was recorded with the application of 75% N-PK + 25% N through vermicompost which was significantly superior to all other treatments during both years, the highest number of tillers per meter row. Lowest number of tillers was recorded in 50% N-PK + 50% N through FYM. | Effect of weed and nutrient management on the growth and yield of barley (Hordeum vulgare L.) and associated weeds
