Abstract:
The aim of the present work was to study the impact of boron and calcium on growth and yield of groundnut cv. BG-4 (Arachis hypogaea L.) under red and lateritic soil (Alfisols) of Jharkhand, India. The experiments were carried out during the Kharif seasons of two years i.e., 2017 and 2018 at research field of Department of Soil Science & Agricultural Chemistry, Birsa Agricultural University, Ranchi, Jharkhand. The experiment consisted of four levels of boron (i.e., @ 0.0, 1.0, 2.0 and 3.0 kg ha^-1) and four levels of lime was used as source of calcium (i.e., @ 0/0, 1/5, 1/10 and 1/15 LR). Each experiment was conducted in Split Plot Design (SPD) with 3 replications by using boron and lime and their interactions was improved in plant growth and yield as compared to the experiments conducted without lime and boron that is in control with the applicable dose of N, P, K and S (@ 80, 60, 40 and 20 kg ha^-1). The significantly superior improvement was observed in plant height and number of pegs and pods per plant in where plot was treated with lime @ 1/5 LR followed by @ 1/10 LR and @1/15 LR among the mean values of both years i.e., 2017 and 2018. In case of grain and straw yield, significantly increased with increasing boron application, in where significantly higher was observed in B₃ (@ 3.0 kg B ha^-1) followed by B₂ (@ 2.0 kg B ha^-1) and B₁ (@ 1.0 kg B ha^-1) among the mean values of both years. The optimum improved in growth and yield of groundnut was recorded from where boron application at the rate of 3.0 kg ha^-1 and lime application @ 1/5 LR. Hence we can be recommended that boron and lime play an important role in red and lateritic soil (Alfisols) of Agro climatic sub zone IV^th of VII^th ACZ (Hill and plateau region) of Jharkhand.
