Effect of Phosphorus and Sulphur using PSB on Groundnut (Arachis hypogaea L.) in Calcareous Soils
Year: 2019
Type: article
Abstract: A field experiment on groundnut (Arachis hypogaea L.) under calcareous soil was conducted during summer 2016 at Instructional Farm, Department of Agronomy, College of Agriculture, JAU, Junagadh. Results of the experiment revealed that significantly higher growth and yield attributes and yield were recorded with RDP @ 50 kg P2O5 ha-1 + 30 kg S ha-1 + PSB. Plant height was at par with RDP + PSB, 30 kg S ha-1 + PSB, RDP + 30 kg S ha-1 and RDP at 60 DAS, RDP + PSB and RDP at 90 DAS, and RDP + PSB and RDP at harvest. Dry matter accumulation of plant was at par with all other treatments except control at both 60 and 90 DAS but significant with RDP + 30 kg S ha-1 at harvest. Pod yield was at par with RDP + 30 kg S ha-1.Significantly higher nutrient content and their uptake, and available nutrients (N, P, K and S) in soil were observed with RDP @ 50 kg P2O5 ha-1 + 30 kg S ha-1 + PSB. P content in plant was at par with RDP + 30 kg S/ha, RDP + PSB and RDP. Significantly higher S content was recorded in 30 kg S ha-1 + PSB, which was at par with RDP + 30 kg S ha-1 + PSB. Uptake of P and S was at par with RDP + 30 kg S ha-1. The available P in soil was at par with RDP + 30 kg S ha-1 at both 60 and 90 DAS and available S in soil was at par with RDP + 30 kg S ha-1.
