Abstract
Mungbean production in Bangladesh is seriously constrained by poor germination, weak seedling establishment, delayed emergence, and a high susceptibility to early-stage stress, resulting in lower yield potential. To overcome these limitations, a study was conducted from February to June 2023 at the Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Bangladesh. This study aimed to evaluate the effects of various seed priming techniques on germination, growth and yield of mungbean. Three varieties BARI Mung-6, BARI Mung-7, and BARI Mung-8 were tested with five priming methods: control (without primed), hydropriming, halopriming (2% NaCl), and hormonal priming using gibberellic acid (GA3) at 100 and 200 ppm. The germination test followed a completely randomized design using petri dish and plastic pots, while field trials used a randomized complete block design with three replications. GA3 at 200 ppm significantly enhanced germination percentage, germination index, plant height, branch number, biomass, seedling vigor, and yield components such as pods plant–1, pod length, seeds pod–1, 1,000-seed weight, and overall yield. The highest yield (565.67 kg ha⁻¹) was observed in BARI Mung-7 primed with GA3 at 200 ppm. In contrast, 2% NaCl priming produced the lowest performance, with BARI Mung-6 yielding only 33.33 kg ha⁻¹. The results suggest that BARI Mung-7, when primed with GA3 at 200 ppm for 24 hours, is optimal for improving mungbean production under the studied conditions.
