Abstract:

A field experiment was conducted at Madabhavi watershed, Karnataka, India, on Typic Chromustert during 1998-2001 on sorghum-sunflower cropping systems to study the effect of sunn hemp and green gram crop residue with inorganic fertilizer on soil properties. The treatments consisted farmer's practice (63 kg urea+63 kg diammonium phosphate (DAP)/ha; the control), in situ incorporation of 5 t sunn hemp+63 kg urea+63 kg DAP/ha, and incorporation of 5 t green gram residue+63 kg urea+63 kg DAP/ha. The available soil water content (cm/m) was higher with in situ sunn hemp or green gram residue incorporations compared to the control (farmer's practice). In situ sunn hemp or green gram residue incorporations decreased the bulk density but increased the infiltration rate, hydraulic conductivity, pore space, and maximum water holding capacity of soils. Green gram residue incorporation and sunn hemp+green manure integrated with chemical fertilizer application increased organic carbon (%) and available P, K and S, secondary and micronutrient [trace element] soil contents compared to farmer's practice.
