LOPEZ-SANCHEZ, Raúl C. et al. Affectations in the yield in common bean (Phaseolus vulgaris L.) varieties caused by salinity. cultrop [online]. 2018, vol.39, n.1, pp. 74-80. ISSN 1819-4087.

The effect of soil salinity was studied in four varieties of common bean (Phaseolus vulgaris L.) from variables related to yield and its components. The varieties were planted simultaneously on two different soils, one saline and other non-saline and distributed in a design in random blocks with four replicates. At 60 days after sowing, the measurement of plant height and the number of folioles at the moment of the harvest was determined: the number of pods per plant, number of grains per pod, weight of 100 grains and yield. The salt inhibition index was also determined in the variables analyzed. The results showed that bean varieties evaluated showed significant affectations in growth and yield and components variables evaluated for the presence of salinity in the soil. The VAM-13 and VAM-14 varieties can be classified as tolerant and VAM-17 and VAM-43 varieties as susceptible considering inhibition rates shown for the indicators evaluated. The salt inhibition index used allows us classifying the lines according to salt tolerance level under field conditions can complement the studies performed to optimize the performance of this crop under conditions of salt stress

Keywords : inhibition; legumes; salinity; tolerance.
