Abstract: The experiment was conducted at Oilseeds Research Farm, CCS Haryana Agricultural University Hisar during rabi 2020-21 to evaluate promising Indian mustard genotypes under different fertility levels under timely irrigated sown conditions. The soil of experimental field was sandy loam in texture, with slightly alkaline in reaction (pH 8.0),low in organic carbon(0.34%), available N (162 kg/ha) were low, P2 05 medium (12.3 kg/ha), and high in K20 (330 kg/ha) and S (29 ppm).The experiment was laid in split-plot design with 7 genotypes (PDZ-12, PDZ-11, RCH-1, RH-749(ZC), PUSA MUSTARD 29, Kranti (NC) and  PDZ 1) in main plots and three fertilizer levels (100% RDF: 80:30:20 kg NP2O5 and K2O/ha, 125% RDF, 150% RDF) in sub plots with 3 replications. Maximum seed yield (2418 kg/ha) was obtained from the mustard genotypes RCH-1, which was significantly higher than the seed yield recorded in PDZ-11 and PDZ-1. RCH-1 was produced 27% and 11.67 % higher seed yield than PDZ -11 and PDZ-1, respectively. With addition of fertilizer, seed yield increased upto 125 % RDF, irrespective of genotypes. Mustard crop did not respond positively at 150 % RDF. Oil content was influenced significantly with mustard genotypes and fertility levels. Maximum oil yield was also produced by RCH-1 (943 kg/ha), being significantly at par with RH 749 and PM-29 and superior to rest of the genotypes. Variation due to interaction effect in mustard genotypes and fertility levels was not found to be significant.
