Effect of Soil and Foliar Application of Boron on Yield and Economics of Green Gram (Vigna radiata L.)

Abstract

A field experiment entitled "Effect of soil and foliar application of boron on yield and economics of green gram" was carried out during Kharif 2019-20 at ZARS, UAS, GKVK, Bengaluru. The field experimental results revealed that significant (p < 0.05) variation in number of pods plant-1 (25.74), number of seeds pod-1 (14.48), test weight of 100 seeds (5.12 g), grain yield (10.19 q ha-1), haulm yield (2.17 t ha-1) and B:C ratio (1.96) were recorded in treatment T10 which received soil application of borax at 2.50 kg ha-1 + foliar application of boric acid at 0.1 % along with package of practice. The number of nodules plant-1 (20.12) was significantly (p < 0.05) highest in treatment T12 which received soil application of borax at 5.00 kg ha-1 + foliar application of boric acid at 0.1% along with RDF over absolute control (14.75). So, from this experiment treatment T10 which received soil application of borax at 2.50 kg ha-1 + foliar application of boric acid at 0.1% along with package of practice shows better results, Since, the present study result one year experiment; further long term and multi-locational trial must be done to confirm the finding.
