S. Seshadri Reddy, B. Shivaraj, V.C. Reddy

Abstract


Field experiments were conducted during kharif seasons of 2002 and 2003 to test the effect of direct and residual fertility on maize. There were two direct fertility treatments and twelve residual fertility treatments. Among direct fertility treatments recommended dose of fertilizer (RDF) recorded significantly higher yield components and grain yield of maize compared to soil test crop response for targeted yields (STCR) approach. Among residual fertility treatments composted poultry manure recorded significantly higher yield components and grain yield compared to urban garbage compost and FYM. However, composted poultry manure was found on par with sewage sludge and enriched urban garbage compost
