Effect of fertilizer management and cutting schedule on yield and quantity of dual purpose barley crop (Hordeum vulgare L.)

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-1along with cutting schedule 45 DAS followed by 100 kg N+50 kg P2O5 ha-1 with cutting schedule 55 DAS
