Abstract
Field Studies were conducted over two years on sandy loam soils, on the influence of boron (B) and zinc (Zn), on nitrate reductase (NR), nitrite reductase (NiR) activities in roots and leaves, and sulfur containing amino acids, viz., cysteine, cystine and methionine; protein, and oil content in seeds of soybean. Enzymatic activities were measured at 30, 60 and 90 days after emergence (DAE). Amino acids, protein and oil content were estimated in seeds after harvest. In absence of B and Zn applications, B and Zn symptoms such as distorted, chlorotic and puckered appearance of leaves, dwarfed plants, impaired flower development and seed set were noted. B and Zn applications were effective in overcoming the B and Zn deficiency symptoms. A significant increase in the nitrate reductase (NR) and nitrite reductase (NiR) activity in roots and leaves were noted. Sulphur containing amino acids (Cysteine, cystine and methionine), protein and oil content in seeds also significantly increased by B and Zn treatments. This work, in part, gives insight in mitigating environmental stresses through applications of micronutrients B and Zn
