Abstract:

An experiment was conducted in the Agronomy Field Laboratory, Sylhet Agricultural University, Sylhet, Bangladesh during the period from January to December 2013 to investigate the performance of mungbean varieties viz., BARI Mung-5 (V2) and BARI Mung-6 (V1) as influenced by sowing dates from January (S1) to December (S12). The experiment was conducted in a Randomized Complete Block Design (RCBD) with three replications assigning the sowing dates and varieties on the plots. Unit plot size was 10 m2 (4.0 m × 2.5 m) with a plant spacing of 30 cm × 10 cm. On an average about 60 days after sowing (DAS) mungbean pods were harvested two times within 10 (ten) days interval for each of the sowing dates. The results of the experiment showed that variety had no significant influence but sowing date and their interaction exerted significant influence on the yield and yield contributing characters of mungbean including plant m-2, number of branches plant-1, number of pods plant-1, number of seeds pod-1, pod length, 1000 seed weight, grain yield, stover yield and harvest index. BARI Mung-6 produced higher yield and yield contributing characters compared to BARI Mung-5. The highest seed yield 693.1 kg ha-1 was obtained from 20 March sowing and the lowest seed yield 196.1 kg ha-1 was obtained from 05 June sowing (S6). It was also found that, both of the varieties gave highest yield on 20 March sowing (S3) and also indicated that yield and yield attributing characters of mungbean were affected for delayed sowing from 20 March. It may be recommend that in Sylhet the mungbean could be cultivated in the month of March, April, June, July and September on the other hand, it should not be cultivated in the month of January, February, November and December due to unavailability of rainfall or moisture and May, August and October for excessive rainfall.
