Field experiments were conducted with sugarcane cv. Co-C 671 (plant and ratoon crops) on alluvial soils during 1994-95 and 1995-96 in farmers' fields of Kovur Sugar Factory area of Nellore district, Andhra Pradesh India. The treatments comprised pressmud cake (PC)+chemical fertilizer (CF), sheep manure (SM)+CF, farmyard manure (FYM)+CF, poultry manure (PM)+CF, and only CF. Sugarcane responded to organic manures when used in integration with inorganic fertilizer. Additional cane yields of 14-27 t/ha were realized with the different organic manure+inorganic fertilizer combinations over inorganic fertilizer alone. FYM+CF, PC+CF and PM+CF were superior over other treatments in terms of cane and sugar yields, as well as quality. Higher uptakes of N, P, K, Ca and Mg were observed in PM+CF-treated plots in both plant and ratoon crops.
