Effect of Spraying Dates for Gibberellic Acid and Boron on some Yield of the Mung Bean

Abstract

Abstract A field experiment was conducted in spring and fall 2023 in the Musayyib project area, 40 km north of Babylon province, in silty loam soil to study the effect of gibberellic acid and boron spraying dates on two mung bean cultivar yield characteristics. Randomized full block design was used for the experiment. The local cultivar had the greatest average pod count 40.57 and 43.43 plant pods-1 for both seasons and varied considerably in all parameters. The local cultivar also had the highest overall seed production and pod seed count. These features averaged 7.692 pod seeds -1 and 1.083 tons ha-1 in fall. The Uzbek cultivar had the greatest average 100 seed weight (6.929 and 6.758 g) for both seasons. The Uzbek cultivar had the maximum spring seed output (9.275 seed pods -1 and 1. 365 tons ha-1). In both seasons, the second spraying date produced the most pods per plant (40.72 and 32.89) pod plant-1. Spring seed production (1.312) tons ha-1 and 100-seed weight (6.038) g were greatest on the third spraying day. Spraying with 200 mg L-1 gibberellin and 200 mg L-1 boron increased most of the studied traits for both seasons and yielded the highest average number of pods (44.64 and 40.15) plant pod-1, the number of seeds per pod (9.139 and 8.632) pod seeds-1, the weight of 100 seeds (6.614 and 5.901) grams, and the total seed yield (1.543 and 1.160) tons ha-1. Most features differed significantly between bi and triple interactions.
