<p>Haplocambid soils are boron (B) deficient, which results in low yield. Among the administration strategies for B, foliar and soil applications as well as seed priming are the most prevalent approaches. Focusing on the mitigation of B deficiency, the present research was carried out in Pakistan and specifically targeted the country’s characteristic sodic Haplocambid/Haplic Yermosols and challenging hyperthermic climatic conditions. The B application techniques encompassed control and three experimental treatments viz. priming of seed with 0.01% B; B application at the rate of 1&#xa0;kg ha^− 1 in soil, and foliar application of B 0.05%. Two mung bean cultivars viz. NM-2011 and NM-2016 were used to test experimental treatments. The experimental results clearly showed that foliar application significantly improved yield traits and yield of both mung bean NM-2016 and NM-2011 cultivars (<i>P</i> ≤ 0.05), with increases observed in plant height by 21–24%, pods per plant by 43–50%, seed number per plant by 44%, pod length by 53%, 100-grain weight by 38%, seed yield by 37–38%, and leaf area index (LAI) by 48%. Furthermore, this application also resulted in statistically significant increases (<i>P</i> ≤ 0.05) in B content in different plant parts (stem by 72–73%, roots by 74–75%, grains by 72–73%, and leaves by 36%), as well as improved grain quality parameters including protein by 10%, fiber by 21%, and carbohydrate content by 3%. In comparison with NM-2011, statistically significant (<i>P</i> ≤ 0.05) enhancement was noted in all parameters of NM-2016. In conclusion, foliar B application at 0.05% markedly enhanced the yield, internal B content, and grain quality of both mung bean cultivars (NM-2011 and MN-2016) in B-deficient Typic Haplocambid soils, demonstrating a highly effective strategy for mitigating deficiency and improving mung bean productivity in these challenging edaphic environments.</p>
