Coss] genotypes under late planting conditions” was carried out at the agronomy research area CCS HAU RRS, Bawal (Rewari) during rabi season of 2003-04. The treatments comprised of four date of sowing viz., (D1) October 27, (D2) November 4, (D3) November 12 and (D4) November 20 and six genotypes viz., (V1) RH – 30, (V2) RH – 8701, (V3) RH – 9801, (V4) RH – 0115, (V5) RH – 0028 and (V6) Vardan. These were tested in split plot design with date of sowing in main and genotypes in sub plots and the 24 treatments combinations were replicated four times. Delay in sowing of Indian mustard crop from Oct., 27 to Nov., 4, 12 and 20 caused progressively significant reduction in seed yield and its attributes viz., number of 2 primary and secondary branches per plant, number of siliquae per plant, number of seeds per siliqua, seed yield per plant and harvest index and growth attributes (height per plant, dry matter per plant and leaf area index), oil content, protein yield, straw and biological yield per hectare, days to completion of siliquae formation and maturity. While the reverse occurred with respect to days to seed germination, days to 50% flowering and protein content. Among various Indian mustard genotpes, RH 0115 recorded significantly higher seed yield over RH 9801, RH 8701, RH 0028, RH 30 and Vardan in descending order due to its better yield attributes (number of siliquae per plant, seeds per siliqua except vardan, 1000-seed weight except RH 30, seed yield per plant, number of primary and secondary branches per plant and harvest index), growth attributes (LAI and dry matter per plant except plant height). It also produced highest oil and protein yield, protein content, biological yield except oil content and straw yield. It took maximum days to maturity and finally fetched maximum net income (Rs./ha).enThesis
