University of Agriculture and Technology, Kugmargaj, Ayodhya, Uttar Pradesh, India Effect of fertilizer management and cutting schedule on yield and quantity of dual purpose barley crop ( Hordeum vulgare L.) Vishuddha Nand, R Yadav, Rajesh Kumar and Sushil Kumar Abstract A field experiment was carried out at Agronomy Research Farm, Narendra Deva University of Agriculture & Technology, Kumarganj, Ayodhaya (U.P.) during Rabi season 2016-17. The experiment was laid out in split plot design with three replications. Main plot were treated with fertilizer levels, F1 (60 kg N+30kg P2O5ha -1 ), F2 (80 kg N+40 kg P2O5 ha -1 ), F3 (100 kg N+50 kg P2O5 ha -1 ) and F4 (120 kg N+60 kg P2O5 ha -1 ) and sub plot were treated with cutting schedule at (first cut taken at different time) at 45 DAS, 55 DAS, 65 DAS and 75 DAS. The data revealed that the maximum grain (2.51 t ha -1 ) and straw yield (4.34 t ha -1 ) and green fodder yield (18.77 t ha -1 ) were obtained with the application of 120 N+ 60 P2O5 kg ha -1 followed by 100 kg N+50 kg P2O5 ha -1 . Similar trend was found in case of yield attributing characters. However, in cutting schedule the maximum green fodder yield (26.40 t ha -1 ) were recorded with cutting on 75 DAS, which was significant higher over rest of the treatments. The maximum cost of cultivation(Rs. 34256 ha -1 ), gross return (Rs. 66170.24 ha -1 ), net return (Rs. 33566.24 ha -1 ) and B:C ratio (1.03) were computed maximum when applied the fertilizers @ 120 N+ 60 P2O5 kg ha -1 along with cutting schedule 45 DAS followed by 100 kg N+50 kg P2O5 ha -1 with cutting schedule 55 DAS. Keywords: Nitrogen & phosphorus, barley, green fodder, yield, cutting schedule and economics Introduction Barley (Hordeum vulgare L.) grain largest use as animal feed in all over the world and in India also, a major share of barley grain is used as animal feed either alone or mixture with fodder crops. Barley has tremendous potential and variation for production of very high amount of digestible dry matter as well as protein yield per hectare. It is grown successfully in a wider range of climatic conditions than any other cereals. Barley has such morpho-physiological traits that make it suitable for dual purpose cultivation for fodder and grain production than other cereals. It is highly efficient in the utilization of water and nutrients in limiting conditions. It is high capacity of crop for tillering and re-growth after cutting and additional capacity for large accumulation of biomass. It sets seed rapidly after re-growth, thus escaping terminal stress due to high temperature and warm winds often experienced in the region. Thus, as a dual purpose (green forage and feed/grain) crop it provides a welcome boost to the confidence of forage growers and fits well for crop diversification in the integrated crop- livestock farming system. Area under barley in world is 47.5 mha with 123.7 mt production and 2.68 t/ha productivity. Russian federation holds first position in all over the world in terms of area and production with 4.94 mha and 8.35 mt respectively (FAOSTAT, 2016). In India, barley is an important coarse cereal crop, being grown in rabi season in northern plains and hills. Area under the barley crop is mainly concentrated in the states namely, Rajasthan, Uttar Pradesh, Madhya Pradesh, Punjab, Haryana, and Bihar in plains and Himachal Pradesh, Uttarakhand and Jammu & Kashmir in the hills. In India, barley crop was grown over an area of 695.0 thousand hectare with a production of 1743.2 thousand tonnes and productivity of 2.51 t ha -1 during 2012-13 (Anonymous, 2013) [1] . Uttar Pradesh is one of the most important barley growing states of India. In Uttar Pradesh, the area under cultivation of barley is about 168.0 thousand ha -1 with a production of 441.0 thousand tonnes and productivity of 2.63 t ha -1 (Anonymous, 2013) [1] . Dual purpose barley is an excellent alternate crop for fodder purpose. .Stage of harvesting is one of the most important factors which determine the higher production level with higher nutritive value. The nutritive value of green fodder is highest at 50% flowering stage and decreases after flowering stage in most of the crops.
