Abstract:
To study the effect of zinc and boron on content and uptake of macronutrients by Cowpea (Vigna unguiculata L. Walp) a field experiment was conducted at the Research and Education Farm, Department of Agricultural Botany, College of Agriculture, Dapoli (Maharashtra) on alfisols deficient in available zinc and boron. Results showed that N, P and K contents in stover at flowering (3.55, 0.336 and 2.52) stover at harvest (2.57, 0.183 and 1.77 ) and seed (2.77, 0.311 and 1.20) and their uptake in stover at harvest (85.93,6.08 and 59.33) uptake in seed at harvest (62.34,6.98, and27.24 ) and Total uptake (148.27,13.06 and 86.57) was significantly increased due to application of 25:60:40 N :P₂0 : K₂0 kg ha^-1 + Rhizobium and PSB @ 25 g kg^-1 seed + B @ 2.00 + Zn @ 7.5 kg ha^-1. Further the content and uptake of N, P and K increased in the treatment which received increased level of zinc and boron application.
