Abstract:
A field trial was laid out in split plot design with tree replications and three dates of sowing as a main plot viz., 10th July, 1st and 20th August and four genotypes as a subplot viz., BSMR-736, TS-3R, Asha and Maruti. The crop sown on 10th July recorded 62 and 69 per cent higher seed yield over crop sown on 1th and 20 th August, respectively. The higher mean yield of 10 th July early sown crop may be ascribed to improved sink capacity and was evident from increased pod number, pod weight, 100seed weight, seeds per pod, flower production, peduncles and harvest index. The higher sink capacity of early sown crop can be traced back to higher mean value of source parameters viz;, Leaf area, Leaf are duration, Total dry matter, leaf dry matter, and chlorophyll content which are pre requisite for better productivity of the crop. Interestingly, early sown crop (10th July) also recorded not only significantly higher flower production, but also higher pod drop, flower drop and higher leaf drop over late sown crop. Among the genotypes studied, cv. Asha recorded, 11.25, 22.85 and 15.62 per cent more seed yield over BSMR-736, TS-3R and Maruti, respectively.
