Salt stress in cowpea plants on biofertilized soil = Estresse salino em plantas de feijão-caupi em solo com fertilizantes orgânicos.
subject: Organic inputs, Physiological indices, salinization
description: The use of organic fertilizer from animal waste can mitigate the harmful effects of salinity of irrigation water on the plants. This experiment was performed in the experimental area of the Universidade Federal do Ceará, Weather Station (EstaçãoMeteorológica), from September to November 2012, aiming at evaluate the response of the cowpea (Vigna unguiculata L.)to salinity levels and biofertilizer types in a greenhouse. The experimental design was that of completely randomized, 5x3factorialwith five replications. The first factor consisted of electrical conductivity of irrigation water levels, as follows: 0.8 dS m-1; 1.5 dS m-1; 3.0 dS m-1; 4.5 dS m-1 and 6.0 dS m-1; and the second factor comprised three conditions: without biofertilizers (B0), with enriched crabbio fertilizer (B1) and with bovine common biofertilizer (B3). The evaluated variables were: photosynthesis, leaf temperature, transpiration, stomatal conductance, plant height, stem diameter, number of leaves, leaf area, and shoot dry mass. The crab enriched biofertilizer more efficiently mitigates the salt stress on plant height, stem diameter, number of leaves, leaf area, photosynthesis, transpiration and stomatal conductance of cowpea cultivar BRS ITAIM compared to plants with biofertilizer and biofertilizer bovine common. The biofertilizer of crab enriched more efficiently mitigates the salt stress on plant height, stem diameter, number of leaves, leaf area, photosynthesis, transpiration and stomatal conductance of cowpea cultivar BRS ITAIM compared to plants without biofertilizer and bovine common biofertilizer. = O uso de fertilizantes orgânicos provenientes de resíduos de origem animal pode atenuar os efeitos danosos da salinidade da água de irrigação sobre as plantas.
