OAR@ICRISATEffect of land management and cropping systems on runoff, soil loss, soil water dynamics and crop yield in a vertisol of central IndiaK MHatiauthorR SChaudharyauthorK GMandalauthorR KSinghauthorS PWaniauthorPSinghauthorPPathakauthorSustainable crop production under rainfed condition can be achieved by conservation of excess rainwater and its efficient recycling. The rainwater can be conserved ex-situ in natural or man-made water harvesting structures. In-situ conservation of rainwater can be achieved through various tillage and landform treatments. A field experiment was conducted for three years from 2003-04 to 2005-06 on a Vertisol (Typic Haplustert) in a mini-watershed at the research farm of the Indian Institute of Soil Science, Bhopal to study the effect of broad bed and furrow (BBF) and flat on grade (FOG) land management treatments on the runoff and soil loss, and to evaluate the productivity of five soybean and maize based sole and intercropping systems under the two land management treatments. The results showed that runoff and soil losses from BBF were lower by 24-32% and 31-55%, respectively, than that from the FOG treatment during the study period. Further, the BBF retained 14 to 23 mm higher soil water in 90 cm soil profile during the later phase of crop growth after the withdrawal of monsoon and produced higher crop yield than the FOG treatment. The total system productivity was found to be higher in maize than soybean based cropping systems in two out of three years of the study. The study provides an option for crop diversification from the present soybean-wheat system to maize-chickpea, soybean/maize-chickpea or maize/pigeon pea intercropping system for the Vertisols of central IndiaSoil Science2013Indian Sociely of Soii ScienceArticle
