A field experiment was conducted to study the response of rabi sorghum genotypes (Sorghum bicolor (L) Moench) to different fertility levels under rainfed conditions at AICRP on Sorghum, Main Agricultural Research Station, Dharwad (Karnataka) during rabi, 2017. The experiment was laid out in split plot design with twenty four treatment combinations and three replications. The treatments consisted of eight genotypes in main plots and three fertility levels in sub plots. Application of 100% RDF recorded significantly higher plant height (175.0 cm), 100-seed weight (3.94 g), ear weight (95.8 g), grain yield/plant (49.5 g), grain yield (50.2 q/ha), fodder yield (7.83 t/ha), gross returns (Rs. 1,11,468/ha), net returns (Rs. 76,413/ha) and B: C ratio (3.18) compared to other fertility levels. Both the test hybrids, SPH-1835 and SPH-1836 produced higher grain yield compared to check hybrids (CSH-13R and CSH-15R). Test variety SPV-2405 also recorded higher grain yield (50.4 q/ha), fodder yield (8.07 t/ha) and net returns (Rs. 78,238/ha) compared to test variety (SPV-2348) and check variety (CSV-29R).
