Abstract:

The present investigation was conducted during kharif 2016-17 with a view to study the effect of various tillage and IPNS practices on soil biological properties under soybean –cotton rotation in Vertisol. The experiment was conducted at Research Farm, Department of Soil Science and Agricultural Chemistry, Dr. PDKV, Akola. The experiment was carried out with main plot comprises two treatments i.e. conservation tillage (CNS) (one harrowing and two weeding) and conventional tillage (CNV) (one ploughing, one harrowing, two hoeing and two hand weeding) and eight sub plot treatments of integrated plant nutrient system consisting of control, 100 per cent RDF and use of chemical fertilizer along with organic source of nutrient in which 50 per cent N applied through organic sources (FYM, wheat straw, Glyricidia leaf manuring (GLM), composted cotton straw, Vermicompost and Phosphocompost) and remaining N was applied through chemical fertilizers. The soybean variety JS-335 was undertaken for the experiment with general recommended dose of fertilizer 30:75:30 N, P2O5, K2O kg ha-1. The experiment was framed in randomized block design (RBD) with three replications. Among the tillage practices, significantly higher soybean seed yield and biological properties viz., SMBC (276 µg g-1), DHA (67.72 µgTPF g-1 24 h-1), CO2 evolution (68.58 mg 100 g-1 soil) and SOC stock (11.85 Mg ha-1) were recorded in conservation tillage as compared to conventional tillage under soybean-cotton rotation. The various integrated plant nutrient supply treatments influenced significantly highest biological properties viz., SMBC (279 µg g-1), DHA (72.25 µgTPF g-1 24 h-1), CO2 evolution (71.25 mg 100 g-1 soil) and SOC stock (12.16 Mg ha-1) were recorded with the application of FYM in conjunction with chemical fertilizers. Whereas, the highest seed yield was recorded with the application of phosphocompost along with chemical fertilizer.
