- Abstract
Objective of this work was to evaluate the effect of irrigation with water of high and low salinity on the initial growth of tomato plants grown in soil fertilized with biofertilizer. The experiment was carried out in the period from March to April 2016, in the experimental area of the Universidade Federal do Ceará, Fortaleza, Ceará. The experimental design was a completely randomized design (DIC) in a 5x2 factorial scheme, with four replications, referring to five concentrations of biofertilizer: C1 = 20%, C2 = 40%, C3 = 60%, C4 = 80%, C5 = 100% and two salinity levels of irrigation water for S1 = 0.8 dS m-1 (low salinity) and S2 = 3.4 dS m-1 (high salinity). We analyzed the electrical conductivity of the soil and the initial growth of plants using the following variables: plant height, stem diameter, number of sheets, dry matter of aerial part, root and total dry matter. Increased concentration of bovine biofertilizer provided higher plant height when irrigated with low salinity water. The bovine biofertilizer was efficient in the growth and accumulation of biomass in tomato plants.
