Effect of Phosphorus Levels and Foliar Application of Boron on Nutrient Content and Uptake in Summer Green Gram [Vigna radiata (L.)]

Phosphorus and boron are essential nutrients that play a crucial role in improving nutrient enrichment, and seed quality in legumes, especially under low-productivity conditions. Therefore, to evaluate the effect of phosphorus and boron application on enrichment of seed and straw of green gram, a field experiment was conducted at Agronomy Research Farm, MJRP College of Agriculture and Research, Achrol, Jaipur, Rajasthan. The experiment comprised of three levels of phosphorus (40, 50 and 60 kg ha-1) and 4 foliar applications of boron (0, 0.2% at 20, 0.2% at 35 and 0.2% at both 20 & 35 days after sowing) under a Factorial Randomized Block Design (FRBD) with three replications. The results of the study revealed that application of phosphorus and boron have synergistic effect on P and B content in seed and straw of green gram. Highest content of P and B in seed and straw was found when 60 kg ha-1 P along with foliar application of boron at 0.2% at 20 and 35 DAS (days after sowing). Application of P and B also improve protein content but their interaction was found non-significant. The combined application of 60 kg ha⁻¹ phosphorus and foliar boron at 0.2% at both 20 and 35 days after sowing significantly enhances phosphorus and boron content in seed and straw of green gram, thereby improving nutrient enrichment under low-productivity conditions.
