Effects of Nitrogen and Phosphorus Application at Different Levels on Performance of Pea (Pisum sativum L.) in Agroclimatic Zone-II of Himachal Pradesh, India

Abstract

During the Rabi season of 2023-24, a field experiment was carried out at Agriculture Farm Chamelti, Shoolini University of Biotechnology and Management Sciences Solan (H.P.). The soil in the experimental field was well-drained, with medium in organic carbon and available nitrogen, but high in available phosphorus and potassium. Four nitrogen levels viz., N0- Control, N1- 15 kg ha-1 + Nano urea (2 ml L-1), N2- 20 kg ha-1, N3- 25 kg ha-1 and four levels of phosphorus viz., P0- Control, P1- 20 kg ha-1, P2- 40 kg ha-1 + Nano DAP (2 ml L-1), P3- 60 kg ha-1 and the GS-10 variety of pea was tested in Factorial Randomized Block Design (FRBD) with three replications. The experimental field results showed that applying nitrogen @ 25 kg ha-1 (N3) and phosphorus @ 60 kg ha-1 (P3) produced maximum growth parameters (plant height, number of branches plant-1, number of leaves plant-1, dry matter accumulation (g plant-1), yield contributing traits (pod length, number of pods plant-1, and number of grains pod-1), and yield (grains, stover, and biological). Furthermore, it increased gross returns, net returns, and the B:C ratio when compared to other levels of nitrogen and phosphorus.
