Salt tolerance in mungbean is influenced by application of phosphorus in sand culture

Abstract

Salinity stress is major abiotic stress which limits growth and productivity of plants in many areas of the world. Nutrient imbalance on the other hand, is one of the major abiotic constraints limiting productivity of pulses. Mungbean is ecologically important legume crop and its susceptibility towards salinity stress has limited the production. Fertilization management is an important technique to alleviate the adverse effects of salinity stress on plants. The present study was carried out to assess various effects of phosphorus application on salt tolerance and to determine effect of phosphorus on morphological and biochemical parameters of mungbean under induced salt stress. Mungbean genotypes were sown in plastic pots filled with sand and grown with recommended packages of practices. It was found that phosphorus (2mM) alleviated salt stress (50mM) as morphological and biochemical parameters showed increased responses when phosphorus was applied along with salt stress. Thus, it can be concluded that phosphorus mitigates the effects of inducedsalt stress responses in mungbean.
