Effect of boron on yield and quality of groundnut (Arachis hypogaea) on lateritic soil

Abstract

A field experiment was conducted during the winter seasons (rabi) of 1988-89 and 1989-90 on lateritic soil to study the effect of boron on yield and quality of 'SB 11' groundnut (Arachis hypogaea L.). The treatments were: T₁, no boron; T₂, soil application of n @ 0.5 kg/ha through horonaled superphosphate; T₃, 0.5 kg/ha through borax.; 14, 1.0 kg/ha through borax; T₅, 1.5 kg/ha through borax; and T₆, B @ 0.5 ppm in Z foliar sprays. Treatment T₂ gave significantly higher yield of dry pods (3200 kg/ha) and harvest index (42.84) than all other treatments. It also gave significantly higher yield of oil (1 156 kg/ha) and protein (659 kg/ha) and showed higher uptake of nitrogen (127.4 kg/ha) and phosphorus (11.7 kg/ha) in-kernels than T₂, T₃, T₄ and T₅.
