Abstract
A field experiment entitled "Effect of soil and foliar application of boron on soil properties, growth, yield and quality of green gram (Vigna radiata L.)" was carried out during Kharif 2019-20 at ZARS, UAS, GKVK, Bangalore. The experiment comprised of twelve treatments, replicated thrice with RCBD. The results indicated that significantly higher available nitrogen (275.3 kg ha-1), available potassium (156.74 kg ha-1), exchangeable calcium (2.88 c mol (p) kg-1) and available sulphur (275.3 kg ha-1) were
recorded in package of practice (FYM 7.50 t ha-1 + NPK 12.5:25:12.5 kg ha-1 + ZnSO4 10 kg ha-1), while significantly higher available phosphorus (28.12 kg ha-1) and available boron (0.57 mg kg-1) were recorded in treatment which received soil application of borax at 7.50 kg ha-1along with package of practice. Whereas, soil application of borax at 2.50 kg ha-1 + foliar application of boric acid at 0.1 % along with package of practice recorded significantly higher plant height (50.82 cm), number of branches plant-1 (8.29), seed yield (10.19 q ha-1), haulm yield (2.17 t ha-1) and B:C ratio (1.96). While, significantly higher crude protein content (25.38 %) in seed was noticed in treatment which received
soil application of borax at 5.00 kg ha-1 + foliar application of boric acid at 0.1 % along with package of practice. However, soil application of borax at 7.5 kg ha-1along with package of practice recorded significantly higher uptake of boron (36.62 and 64.33 g ha-1) by seed and haulm of green gram, respectively.
