SEED YIELD AND QUALITY OF MUNGBEAN AS AFFECTED BY SEED PRIMING

Abstract

An experiment was carried out at Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh during the period from November 2017 to February 2018 to study the seed yield and quality of mungbean as affected by seed priming. The whole experiment was conducted in two different phases; the first at field condition and second in the Laboratory. Two varieties of mungbean viz. V 1 (BARI mung 6) and V

(BARI mung 8) and different priming chemicals including control viz. T (control; No priming), T 1 (seed priming with water), T 2 (seed priming with PEG) and T (seed priming with Mannitol) were considered as treatments of the experiment. The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The data on different parameters at field level and laboratory condition were recorded. Collected data were statistically analyzed. Variety, seed priming treatments and their combination showed significant influence on different growth and yield parameters. The highest grain yield ha -1 (1299.90 kg) and percent seedling emergence (84.20%) were found from V (BARI mung 6) whereas the lowest grain yield ha -1 1 (1201.05 kg) and percent seedling emergence (81.34%) was from V (BARI mung 8). Similarly, the highest grain yield ha -1 (1523.40 kg) and highest percent seedling emergence (91.45%) were achieved from the priming treatment, T (seed priming with Mannitol) compared to control. Regarding, interaction effect of variety and seed priming treatments, the highest number of branches plant -1 (2.70, 4.60 and 5.12 at 25, 40 and 55 DAS, respectively), number of pods plant -1 (26.60), 1000 seed weight (51.12 g), grain weight plant -1 (15.30 g) and grain yield ha -1 (1572.20 kg) were found from the treatment combination, V 1 T 3 while the lowest from V . The lowest days to 50% flowering (38.67) and days to 80% pod formation (48.67) were also found from the treatment combination of V 1 T . The highest percent seedling emergence (92.30%) was also found from V 1 T 3 3 whereas the lowest (70.75%) was from the V 2 T 0 . It can be concluded that the treatment combination of V can be considered as the best considering all other treatment combinations. 2 0 T 0 1 T 2 3 3 3 2
