Assessment of Soybean (Glycine max Merill L.) Based Cropping Systems through Organic and Inorganic inputs in Bundelkhand Region

A field experiment was conducted at Tulsi Krishi Vigyan Kendra, Chitrakoot, Uttar Pradesh during 2012–13 to 2015–16 to study the effect of organic and inorganic inputs on productivity of soybean (Glycine max L. Merill) based cropping systems. Two cropping systems viz., soybean-wheat and soybeanchick pea along with three crop management practices viz., organic, inorganic and integrated were evaluated in strip plot design with four replications. In kharif season, soybean seed yield in soybeanwheat system (2718 kg/ha) was at par with soybean-chickpea (2662 kg/ha) cropping system. Amongst the management practices, organic practice gave significantly higher soybean seed yield (2850 kg/ha) than inorganic (2592 kg/ha) and integrated (2629 kg/ha) practice of crop management. However in rabi season, wheat (4017 kg/ha) recorded significantly higher yield than chickpea (1065 kg/ha). Inorganic management (2829 kg/ha) recorded significantly highest yield followed by integrated (2698 kg/ha) and organic practice (2097 kg/ha) during season. Soybean equivalent yield (SEY) was significantly higher in soybean-wheat cropping system (2595 kg/ha) than soybean-chickpea (1304 kg/ha). Inorganic practice showed significantly higher SEY (2129 kg/ha) than other two management practices. System net returns were higher in soybean-wheat system (Rs. 86964/-ha) and in inorganic practice (Rs. 97176/-ha) than in soybean-chickpea cropping system (Rs. 57872/-ha) and rest of the two management practices. Soybeanwheat cropping system with inorganic practice recorded higher system productivity (5573 kg/ha).
