Assessment of mungbean (Vigna radiata L.) cultivars in relation to phosphorus utilization efficiency under phosphorus stress environment

Abstract

The present study was conducted during kharif season of 2019 with 24 diverse mungbean cultivars under the hydroponic system at the Indian Agricultural Research Institute, New Delhi to assess the phosphorus utilization efficiency of genotypes under a phosphorus stress environment. Cultivars differed significantly for biomass accumulation, P concentration, total P uptake and PUtE. Categorization based on PUtE and total dry weight, cultivars MH 521, MH 805 and PM 5 were identified as efficient and responsive (ER) under LP condition. The phosphorus stress factor values indicated the varied response of cultivars to P stress. The identified efficient genotypes could be used in themungbean breeding programme for P efficiency improvement.
