- Abstract
The high temperatures and low rainfall salinize water and soil in the Northeast Region, causing a reduction in the development of several species, among them, fava bean. The objective of this study was to evaluate bean-fava varieties submitted to levels of salinity and organic fertilization. The study was conducted in a protected environment, in the dependencies of the Federal University of Campina Grande, Pombal campus. The experimental design was a randomized block design, arranged in a 3x4x5 factorial scheme: three varieties of bean (V1: lavandeira, V2: sunshine and V3: rajada), four volumes of bovine manure (A1: 0% - without fertilization; A2: 8%; A3: 16% and A4: 24%), applied as a function of the soil volume of the container and five levels of salinity in the irrigation water (S1 = 0.3 dSm-1; S2 = 1.0 dSm-1; S3 = 1.7 dSm-1; S4 = 2.4 dSm-1 and S5 = 3.1 dSm-1). The Raio de Sol variety presented higher growth in relation to the others, however, the cultivar Rajada presented a higher acclimatization to saline conditions, mainly with the use of bovine manure in the concentration of 24%. Bovine manure attenuates the harmful effect of salinity, however, doses above 16% of manure at high salinity can be harmful to common bean.
