Abstract

Plants grown under salt stress are adversely affected, however, it has been suggested the use of organic inputs in order to mitigate the deleterious effects of salinity. As a result, it aimed to evaluate the effect of different electrical conductivities of irrigation water due to the application of organic fertilizers in the cultivation of castor bean. The experiment was conducted in greenhouse located at State University of Paraiba, municipality of Catolé do Rocha-PB, Brazil. It adopted a completely randomized design (CRD), in a factorial scheme 5 x 3, with 8 repetitions. The first factor was the electrical conductivity of irrigation water (ECw) 0.5; 1.5; 2.5; 3.5 and 4.5 dS m-1 and the second factor refers to organic fertilizers: control treatment, biofertilizers beef and cow urine. There was interaction between the electrical conductivity x organic fertilizer factors. The unit increased from 0.5 dS m-1 of electrical conductivity of irrigation water reduced the growth, development and dry matter production of castor bean. The application of bovine growth provides greater biofertilizer castor. Furthermore, the organic raw material attenuates the effects of salt stress.

Key words: Ricinus communis L. salt stress, biofertilizer, cow urine.
