Biomass Production, Productivity and Physiological Changes in Moth Bean Genotypes at Different Salinity Levels

Nishi Mathur, Joginder Singh, Sachendra Bohra, Avinash Bohra and Anil Vyas

Abstract:
Responses of three genotypes (CZM-105, HM-61 and RMB-108) of moth bean (Vigna aconitifolia) grown under four levels of NaCl salinity (0, 5, 10 and 15 dS m-1) were studied on plant growth, seed yield and nitrogen metabolism at the maturity stage. Increasing salinity levels progressively decreased plant height, leaf area, shoot dry matter and seed yield in all the genotypes. However, CZM 105, displayed higher salt tolerance whereas RMB-108 was most sensitive with 48.5% reduction in seed yield at 15 dS m-1 of NaCl. Genotype HM-61 displayed an intermediate tolerance to salinity. Salt-induced changes in the levels of total chlorophyll, soluble protein, free amino acids and activities of nitrate reductase, glutamine synthetase, glutamate synthase and glutamate dehydrogenase were consistently less in tolerant genotype CZM 105 as compared to moderately tolerant HM-61 and salt sensitive genotype RMB-108 at all levels of salinity.
