Abstract
A field experiment was conducted on a Typic Haplustept at experimental farm of the Indian Agricultural Research Institute, New Delhi, during three consecutive kharif seasons of the year 2006, 2007 and 2008, to assess the possibility of improving productivity and sustainability of cowpea under 100% recommended doses of NPK fertilizers and 50% recommended doses of NPK fertilizers along with sewage sludge @ 1 t ha-1 and rice straw in the ratio of (1:3, 1:6 and 1:9). Application of N, P, K and organic sources (sewage sludge plus rice straw) significantly increased the yield of cowpea over control. The maximum yield of cowpea (10.9 q ha-1) was obtained in 100% NPK followed by 50% NPK + sewage sludge: rice straw (1:9). The 100% recommended NPK recorded higher N, P and K uptake which was at par with the treatment 50% NPK + sewage sludge : rice straw (1:9). Combined use of organics and fertilizer was significantly reflected in the buildup of available N, P, K and organic carbon. The use of rice straw along with sewage sludge decreased the DTPA-extractable Cd, Pb and Ni content in soil.
