Effect of different NPK doses on the performance of green gram (Vigna radiata L.) cultivar in Central Uttar Pradesh

Abstract

The objective of the study was to evaluate the growth response of mungbean [Vigna radiata (L.)] cultivars subjected to different levels of applied N fertilizer. To achieve the aim, an experiment conducted in the experimental field of University Research Farm, Rama University Mandhana, Kanpur 209217 (U.P.). The soil of the study area was basic in reaction, salt free, medium textured having low organic matter & total N contents. Three different cultivars of mungbean viz., (IPM 02-3, PDM-139, IPM 410-3) grown in kharif season for one consecutive years i.e., 2023. Three different levels of RDF applied @ 75%, 100% and 125% ha-1. While, a constant dose of P2O5 and K2O also applied to each N level (except control, zero). Urea fertilizer used as a source of N, while DAP and MOP as sources of P & K, respectively. The plot size kept as 21 m2 (7x3), and arranged in a Spilt plot design (SPD). Results showed that different fertilizer levels did significantly (p
