Effect of zinc and boron on growth and yield of greengram (Vigna radiata L.)

Abstract

A field experiment was conducted during Zaid season of 2023 at Crop Research Farm Department of Agronomy, Naini Agriculture Institute, Sam Higginbottom University of Agriculture Sciences and Technology. To determine “Effect of zinc and boron on Growth and Yield of greengram” The result revealed that treatment 9 [15 kg/ha zinc + 1.5 kg/ha boron] recorded significantly higher plant height (42.57 cm), higher nodules/plant (17.27), higher branches/plant (6.70), higher plant dry weight (16.88 g), higher crop growth rate (23.18 g/m²/day), higher relative crop growth rate (0.1358), higher pods/plant (14.2), higher seeds/pod (12.51), higher test weight (39.05), higher seed yield (1.37 t/ha) and higher stover yield (3.20t/ha), higher harvest index (30.41%). the aforesaid treatment also recorded maximum gross return (INR105746.96/ha), net return (INR74906.96/ha) and B:C ratio (2.43).
