An experiment was conducted at the research field of the Department of Agronomy and Haor Agriculture, Sylhet Agricultural University, Sylhet-3100 during Kharif 2 Season to find out the effect of plant spacing on the yield of mungbean varieties. The experiment was conducted considering two factors, mungbean varieties viz., BARI mung-6 (V₁) and Patuakhali local (V₂),plant spacing’s viz., S₁= (30cm × 15cm),S₂= (30cm × 10cm), S₃= (30cm × 5cm). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The results showed significant variation in important yield parameters like podsplant^-1, seeds pod^-1 and seed yield. The interaction effect indicated that BARI mung-6 with moderate and closer spacing had the highest number of pods plant^-1 (9.27 and 9.00, respectively); on the other hand the highest seeds pod^-1 (12.27) was produced in Patuakhali local variety with closer spacing. The variety BARI mung-6 produced the highest seed yield of 825.32 kg ha^-1 with closer plant spacing which was statistically similar in Patuakhali local variety in highest and moderate spacing but the lowest seed yield (606.1 kg ha^-1) was produced in Patuakhali local variety with closer spacing. Therefore, BARI mung-6 with closer spacing (30cm × 5cm) can be recommended to cultivate mungbean during Kharif 2 season in Sylhet region.

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.

An experiment was conducted at Pulses Research Sub-Station (PRSS), Bangladesh Agricultural Research Institute, Joydevpur, Gazipur and Regional Agricultural Research Station (RARS), Jessore, Bangladesh during kharif-1, 2014 under rain fed condition to find out the tolerant genotypes against Mungbean Yellow Mosaic Virus (MYMV) where viz. Gk – 22, SMZ – 134, VC – 3669, VC – 3960 A – 88, VC – 3960 A – 89, VC 6144, VC – 6144 (47 – 28 – 2), VC – 6148 (50 – 12), VC – 6153 – B – 20, VC – 6153 – 20P, VC – 6173, VC – 6173 B – 33, VC – 6372 – (45 – 8), VC – 6773 – B – 6, VC – 6897 and BARI Mung – 4 Mungbean genotypes were screened. It was found that the genotype VC – 6153 – B – 20 may be a wonderful source of MYMV tolerance. In the same time another experiment was carried out at Golapgonj, Sylhet and PRSS, Joydevpur for development of management package against the vector of this virus. For these reason five different treatments namely Furadan 3G, Furadan + Admire, Furadan + Neem leaf extract (NLE), Furadan + Sobicron and control were used, where Furadan treated as a basal dose. It was observed that Furadan + Admire treated plots have the lowest incidence (score – 2) of MYMV at both locations and produced the highest yields as compared to the other treatments. It is recommended that Admire can be used as a package for controlling MYMV.
