Abstract
Study was conducted on deep Vertisols to evaluate the influence of tillage and fertilizer levels on performance ofsunflower hybrids in paddy fallows. Sunflower hybrids were grown in conventional-till (CT), Minimum-till (MT),Reduced-till (RT) and zero-till (ZT) with graded fertilization. Averaged across fertilizer rates, cultivars, and years,sunflower seed yields were greater with CT (1477 kg/ha) than with MT, RT and ZT. Graded fertilizers at 150% RDF(1424 kg/ha) increased grain yield over RDF and reduced level at 75% RDF but varied over years. Economic returns also higher in CT along with graded fertilizers for RSFH-1887. Results indicate sunflower can be grown successfully in paddy fallows with CT and MT and graded fertilization in the Vertisols.
