The semiarid presents a high evaporation rate of water, requiring irrigation to produce, making soil salinization susceptible. the objective was to investigate the effect of the use of bovine biofertilizer, and a biological fertilizer, as a function of irrigation with saline water, in the cultivation of beet. The design was in randomized blocks, using factorial scheme 5 x 2 +1. Referring to five electrical conductivity of water (0.5, 1.5, 3.0, 4.5 e 6.0 dSm-1), two bovine biofertilizers , biofertilizer free of microgeo (BIO I) and a biofertilizer containing Microgeo (BIO II) and a witness (not containing organic fertilizer and electrical conductivity of water 0,5 dSm-1). The experiment was conducted in an agricultural greenhouse, located in the Agriculture sector of the Center for Social and Agrarian Human Sciences, Federal University of Paraíba, city of Bananeiras. The biofertilizers were not statistically different. But it has alleviated the deleterious effects of salt water irrigation on plant growth characteristics, except for leaf length, at 45 days after planting. the biofertilizers were not different from each other, but exceeded the plants without the respective inputs. The properly supplied beets tolerate the effects of saline stress.
