Improvement of Drought Tolerance and Yield of Mungbean through Potassium Fertilization with Rhizobium Inoculants

: A pot trail was implemented at the net house of Patuakhali Science and Technology University, Dumki, Patuakhali during the dated from February to April, 2025 to study the drought tolerance and production of mungbean that are impacted by Potassium (K) fertilization and Rhizobium inoculation. The mungbean seed was treated with Rhizobium inoculant at 3% of seed weight before sowing. Seven levels of potassium fertilizer (0, 9.0,7.5, 6.0, 4.5, 3.0, 1.5 g/10 kg soil) were used as treatment in the study. The study was set out in randomized complete block design (RCBD) with three replications. The stress was put in five leaves (vegetative) and silking (reproductive) stages. The results revealed that growth variable and grain production of mungbean were augmented with the increasing rate of potassium fertilizer level. Thus, the results are encouraging in the application of potassium fertilizer and seed treating with Rhizobium inoculant for sustainable production of mungbean under water deficit conditions.
