Effect of nitrogen and phosphorus levels on growth, yield and quality of summer mungbean [Vigna radiata (L.) Wilczek]

Abstract

A field experiment was conducted at Research Farm of Mewar University, Chittorgarh (Rajasthan) during Summer, 2025 on loamy sand soil, which consisted sixteen treatments viz., two factors with where four levels of nitrogen are (Control, 20, 30 and 40 kgha-1) and four source of phosphorus are (Control, 40, 60 and 80 kg ha-1) in factorial randomized block design (FRBD). The mungbean variety “RMG-492” was used for experiment. Results clearly showed that application of application of nitrogen @ 40 kg ha-1 significantly increased growth attributes viz. plant height, plant dry matter, number of branches plant-1, number of nodules plant-1 and yield parameters viz. number of pods plant-1, number of seeds pod-1, seed, straw and biological yield as compare to rest of the treatments whereas lowest value recorded under control. Further, application of phosphorus @ 80 kgha-1 recorded maximum growth, yield over control. However; there were no interaction was found between nitrogen and phosphorus.
