Yield and yield contributing components of Urdbean as influenced by boron molybdenum and nickel

Abstract

A field experiment was conducted on Yield and yield Contributing Components of Blackgram as influenced by boron molybdenum and nickel at Agricultural college farm, Bapatla during rabi, 2017-18. It consisted of 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) with randomized block design concept and replicated thrice. The results revealed that combined soil application of boron, molybdenum and nickel as basal resulted in the significantly increased and effected yield and yield contributing characters like Number of branches, Number of flowers plant -1 , Number of pods plant -1 , Pod length, number of seeds pod -1 , Pod weight plant -1 , test weight and seed yield ha -1 all the characters were timely recorded and the maximum increase in yield was obtained with B+Mo+Ni (T8) (2144.5 kg ha -1 ) application followed by B+Mo (T5) (1973.0 kg ha -1 ), Mo+Ni (T7) (1912.7 kg ha -1 ) and B+Ni (T6) (1892.3 kg ha -1 ). Ni application alone had no increasing effect on yield, while B (1389.7 kg ha -1 ) and Mo (1526.0 kg ha -1 ) application alone increased the yield.
