Influence of foliar application of boron and zinc on growth and yield of greengram (Vigna radiata L.)

Greengram (Vigna radiata L.), commonly called as mungbean is an important pulse crop grown mainly in Zaid and Kharif season in India. A field experiment was conducted during the Zaid season of 2024 in Greengram crop (Var. Samrat PDM-139) at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, SHUATS, Allahabad (U.P.). The treatments consisted of 3 different levels of Boron i.e. (0.5, 0.75 and 1%) and Zinc i.e. (0.5,1and 1.5%). The experimental field soil was sandy loam in texture, moderately basic in reaction (pH 7.5), available medium organic carbon (0.598%), moderately available phosphorus (28.4kg / ha) and highly available potassium (243.3kg / ha) The result showed that significantly highest growth parameters viz., plant height (41.50 cm), number of nodules/ plant (17.10), dry weight (13.30 g/plant) and yield attributes such as effective pod/plant (19.58), seed/pod (9.33), test weight (29.30 g), seed yield (1386.47 kg / ha) and stover yield (2579.33Kg / ha) were observed with application of foliar spray of Boron 1.0% followed by Zinc 1.5% (T9). Higher gross returns (Rs. 114592.99/ha), net return (Rs. 77298.99/ha) and Benefit Cost Ratio (2.07) was recorded superior with application Boron 1% along with Zinc 1.5% in Treatment 9. It concludes that with the application of Boron 1% along with Zinc 1.5%, performed better in growth and yield of Greengram has recorded highest test weight, grain yield, stover yield, net return and benefit cost ratio and as well as it is economically profitable in the treatment of T9 (Boron 1% + Zinc 1.5%).
