Effect of preceding integrated nutrient management practices in kharif crops on system productivity and profitability of barley-based cropping systems

摘要

The study was conducted for three years from 2013-14 to 2015-16 at CCSHAU, Regional Research Station, Bawal- 123501, Rewari, India to study the effect of different integrated nutrient management practices applied in kharif crops on productivity and profitability of various barley based cropping system. The experiment was laid-out in a split plot design with three replications. The main plot treatments consisted of three cropping systems viz. Pearl millet-barley, Mungbean-barley and Clusterbean-barley and sub-plot treatments comprised of seven nutrient management treatments viz. RDF (Recommended dose of fertilizer), 75 RDF + 5 t FYM/ha, 75 RDF + 2.5 t vermicompost/ ha, 100 RDF + biofertilizer, 75 RDF + 5 t FYM/ha + biofertilizer, 75 RDF + 2.5 t vermicompost/ ha + Biofertilizer and 75 RDF + 5 t FYM/ha. These treatments were applied in kharif crops, while in rabi, barley was grown with RDF only. The soils of the experimental field were loamy sand with low fertility status and poor water holding capacity. The pooled data of three years study revealed that application of 75 RDF + 5 t FYM/ha + biofertilizer applied in Kharif crops (pearl millet, mung bean and clusterbean) produced significantly higher barley equivalent yield (104.93 q/ha) over RDF (90.27 q/ha). Among three cropping systems, clusterbean - barley cropping system recorded 33.7 and 78.5 per cent higher barley equivalent yield than that obtained under mung bean-barley and pearlmillet-barley cropping systems, respectively. Pooled mean of three year data for economical parameters indicated that the application of 75 RDF integrated with 5 t FYM/ha + bio-fertilizer applied in Kharif season fetched highest net returns and benefit: cost ratio (Rs. 63834/ha and 2.07, respectively) over RDF (Rs. 48138/ha and 1.82, respectively). Economic analysis of cropping systems evaluated indicated that clusterbean - barley cropping system was more profitable with highest net returns (Rs. 79404/ha) and B:C ratio (2.26) than mung bean-barley (Net returns : Rs. 51287/ha and B:C ratio : 1.87) and pearlmillet-barley (Net returns : Rs. 31810/ha and B:C ratio : 1.56) cropping systems, respectively.
