Land configuration with Methods of sowing on major cropping sequences of malwa region in vertisols of madhya pradesh

Abstract

The present experiment was conducted at black cotton soil of the Malwa region during 2016-17 and 2017-18 at College of Agriculture, RVSKVV, Indore, Madhya Pradesh. The experiment was aimed to find out the best land configuration with sowing methods for higher productivity of major cropping sequence. The experiment consists of sixteen treatments. All the treatment will be tested in strip plot design with three replications as per following details: The main plot treatments consisted of the land configuration and tillage operation (4) In kharif season, L1: Conventional tillage with flat bed sowing, L2: Minimum tillage with ridge and furrow sowing, L3: Conventional tillage with broad bed furrow and L4: Minimum tillage with broad bed furrow sowing and in rabi season, L1: Zero tillage, L2: Minimum tillage, L3: Minimum tillage with broad bed and L4: Conventional tillage. The sub plot treatments consisted of the cropping system (4) soybean-wheat, soybean-chickpea, maize-wheat and maize-chickpea. The soybean equivalent yield was maximum recorded (42.68 q ha-1) in minimum tillage with ridge and furrow sowing + minimum tillage with soybean-chickpea (41.99 q ha-1). Minimum tillage with ridge and furrow + minimum tillage (17.96 kg ha-1day-1) and soybean-chickpea (18.07 kg ha-1day-1) was found more gain of production efficiency. Profitability of soybean and maize based system was recorded significantly higher in minimum tillage with ridge and furrow sowing + minimum tillage (198 Rs ha-1day-1). In case of cropping system, the significantly higher profitability was recodred in soybean-chickpea (193.50 Rs ha-1day-1). Maximum negative N was estimated with conventional tillage with broad bed furrow sowing to kharif and minimum tillage with broad bed furrow sowing to rabi in soybean chickpea system (-157.27 kg N ha-1). More positive balance of phosphorus in the soil after harvesting of crops was recorded in conventional tillage with flate bed sowing to kharif and zero tillage to rabi in maize-chickpea system (161.42 kg P ha-1).
