“…Significantly higher plant height (35.8 cm), number of pods plant -1 (11.87), seeds pod -1 (4.40), 100-seed weight (38.96g) and seed yield plant -1 (4.92 g) with 75:30 P 2 O 5 :K 2 O kg ha -1 along with 80 kg N ha -1 [34]. Chantal et al, [35] also found that P: K at 46:30 kg ha -1 along with nitrogen fertilizer produces higher grains pod -1 (5), thousand-seed weight (435g) yield (555.2 t ha -1 ) in bean. The effect of Phosphorus and Potassium is increasing 1000-seed weight and seed yield of bean due to potential of potassium to accelerate enzyme activity which lead to synthesis of protein and assimilate translocation.…”

An experiment was conducted at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh to investigate the yield response of French bean (Phaseolus vulgaris L.) as affected by phosphorus and potassium management. The experiment consisted of two factors. Factor A: Phosphorus fertilizer (4 levels) viz. P1=15Kg P ha-1, P2=20 Kg P ha-1 and P3=25 Kg P ha-1 , P4=35 Kg P ha-1 and factor B: Potassium fertilizer (4 levels) viz. K1=0 Kg K ha-1, K2=20 Kg K ha-1, K3=30 Kg K ha-1 and K4=40 Kg K ha-1. The variety BARI Jharsheem-3 was used in this experiment as the test crop. The experiment was laid out in a randomized complete block design (RCBD) with three replications. In case of phosphorus @ 25 kg ha-1 the highest number of pods plant-1 (4.96), pod length (13.34 cm), number of seeds pod-1 (4.54), weight of 1000-seed (431.21 g), seed yield (1.33 t ha-1), stover yield (1.53 t ha-1), biological yield (2.86 t ha-1) and harvest index 46.50% were found. In case of potassium @ 40 kg ha-1, he highest number of pods plant-1 (5.80), pod length (14.89 cm), number of seeds pod-1 (4.24), weight of 1000-seed (430.37 g), seed yield (1.53 t ha-1 ), stover yield (1.46 t ha-1 ), biological yield (2.99 t ha-1) and harvest index 51.17% were found. Interaction effect of phosphorus and potassium the highest number of pods plant-1 (5.18), pod length (13.40 cm), number of seeds pod-1 (4.30), weight of 1000-seed (430.53 g), seed yield (1.40 t ha-1 ), stover yield (1.60 t ha-1 ), biological yield (3.00 t ha-1 ) and harvest index 46.66% were recorded from P @ 25 kg ha-1 and K @ 40 kg ha-1. However, from the study it can be concluded that application of P @ 25 kg ha-1 and K @ 40 kg ha-1 was the most suitable combination for better yield of French bean.

“…Potassium fertilization significantly enhances the yield and quality of mung bean plants. Studies indicate that applying K fertilizers increases seed yield, protein content, and important yield components like thousand seed weight, plant height, seeds per pod, and first pod height 49 , 50 . Different levels of K application improve growth parameters, yield attributes, seed and haulm yields, and economic returns 51 .…”

Uneven rainfall and high temperature cause drought in tropical and subtropical regions which is a major challenge to cultivating summer mung bean. Potassium (K), a major essential nutrient of plants can alleviate water stress (WS) tolerance in plants. A field trial was executed under a rainout shelter with additional K fertilization including recommended K fertilizer (RKF) for relieving the harmful impact of drought in response to water use efficiency (WUE), growth, yield attributes, nutrient content, and yield of mung bean at the Regional Agricultural Research Station, BARI, Ishwardi, Pabna in two successive summer season of 2018 and 2019. Drought-tolerant genotype BMX-08010-2 (G1) and drought-susceptible cultivar BARI Mung-1 (G2) were grown by applying seven K fertilizer levels (KL) using a split-plot design with three replications, where mung bean genotypes were allotted in the main plots, and KL were assigned randomly in the sub-plots. A considerable variation was observed in the measured variables. Depending on the different applied KL and seed yield of mung bean, the water use efficiency (WUE) varied from 4.73 to 8.14 kg ha−1 mm−1. The treatment applying 125% more K with RKF (KL7) under WS gave the maximum WUE (8.14 kg ha−1 mm−1) obtaining a seed yield of 1093.60 kg ha−1. The treatment receiving only RKF under WS (KL2) provided the minimum WUE (4.73 kg ha−1 mm−1) attaining a seed yield of 825.17 kg ha−1. Results showed that various characteristics including nutrients (N, P, K, and S) content in stover and seed, total dry matter (TDM) in different growth stages, leaf area index (LAI), crop growth rate (CGR), root volume (RV), root density (RD), plant height, pod plant−1, pod length, seeds pod−1, seed weight, and seed yield in all pickings increased with increasing K levels, particularly noted with KL7. The highest grain yield (32.52%) was also obtained from KL7 compared to lower K with RKF. Overall, yield varied from 1410.37 kg ha−1 using 281 mm water (KL1; well-watered condition with RKF) to 825.17 kg ha−1 using 175 mm water (KL2). The results exhibited that the application of additional K improves the performance of all traits under WS conditions. Therefore, mung beans cultivating under WS requires additional K to diminish the negative effect of drought, and adequate use of K contributes to accomplishing sustainable productivity.

“…Several physiological and biological processes, as well as the growth and maintenance of plants, need potassium. Min et al, (2013) and Chantal et al, (2019) say that K+ helps plants deal with water stress by keeping cell membranes, aquaporins, water uptake, osmotic adaptation, stomatal control, and ROS detoxification healthy. The goal of this study was to find out if misting potassium and ABA could help people who were dehydrated..…”

to know the effect of ABA acid and potassium on the growth of broad bean (Vicia faba L) plants under water stress conditions (0 and 1000 mg k -1 ) while the third factor was an ABA acid at the concentration of 0.2 mM. The results were as follows: All studied traits decreased under conditions of water stress (plant height, leaf number, leaf area, total soluble carbohydrates [TSC], activity of superoxide dismutase [SOD], and catalase of broad beans) with recorded values of 41 cm, 5.67 leaf plant -1 , 60.57 cm 2 , 11.82 (mg g-1 DW), 155.01 units mg -1 protein min -1 , and 138.59 mg -1 protein min -1 , respectively. The obtained triple interaction treatment was also at 25 ds m -1 + 1000 mg l -1 + 0 ABA, giving the highest values for all studied traits. ABA and potassium apart and together boosted proline, TSC, SOD, and CAT, raising plant height, leaf number, and area. The combined treatment improved plant growth and antioxidant systems, reducing the suppressive effect of water deprivation. ABA and potassium-treated plants showed greater TSC.
