A field trial was conducted with twelve treatments to test the effectiveness of poultry - carbonaceous wastes compost on the soil properties, growth and yield attributes of sunflower (Var - CO1). Application of compost improved the soil fertility by adding humus and nutrients. Compost along with 100% (60: 45: 45 kg NPK ha-1) and 75% (45: 33: 33kg NPK ha-1) recommended NPK increased the growth and yield of sunflower. Among the composts (Poultry droppings and coir pith, poultry droppings and paddy straw, poultry droppings and coir pith with rock phosphate), the coir pith, rock phosphate mixed poultry compost performed well. The coir pith and rock phosphate added poultry compost along with recommended levels of NPK recorded higher yield which was at par with the results of coir pith mixed poultry compost along with 75 per cent levels of recommended N, P and K. Compost application improved the crop yield, soil fertility status and saved 25 per cent of fertilizer.

Application of compost improved the soil fertility by adding humus and nutrients. Compost along with 100% (60: 45: 45 kg NPK ha-1) and 75% (45: 33: 33kg NPK ha-1) recommended NPK increased the growth and yield of sunflower. Among the composts (Poultry droppings and coir pith, poultry droppings and paddy straw, poultry droppings and coir pith with rock phosphate), the coir pith, rock phosphate mixed poultry compost performed well. The coir pith and rock phosphate added poultry compost along with recommended levels of NPK recorded higher yield which was at par with the results of coir pith mixed poultry compost along with 75 per cent levels of recommended N, P and K. Compost application improved the crop yield, soil fertility status and saved 25 per cent of fertilizer.
