Abstract  

A field experiment was conducted on the Influence of Boron Molybdenum and Nickel on Biochemical traits and quality of blackgram (Vigna mungo L. Hepper) at Agricultural college farm, Bapatla during Rabi 2017-18 in randomized block design with eight treatments of micronutrient application viz., control (T₁), B (T₂), Mo (T₃), Ni (T₄), B+Mo (T₅), B+Ni (T₆), Mo+Ni (T₇) and B+Mo+Ni (T₈) replicated thrice. The results revealed that leghaemoglobin content in nodules, activity of urease in leaves and nodules and protein content in seed increased with B, Mo and Ni application individually and in combination. Activity of NR in leaves increased with T₂ to T₈ except Ni (T₄) application alone.
