Abstract


Salinity is one of the major obstacles of modern agriculture, especially in the semi-arid regions, since these have high rates of evaporation and water sources with high salt terrors. Thus, the present study aimed to investigate the attenuating effects of bovine biofertilizer and biological fertilizer under irrigation with saline waters on the morphological behavior of beetroots (Beta vulgaris L.). The design was randomized blocks in a factorial scheme 4 × 2 + 1, referring to the electrical conductivity of the irrigation water (ECw: 0.5, 1.5, 3.0 and 6.0 dS m-1) and application of bovine biofertilizer in the absence (BIO I), and presence of Microgeo® (BIO II) and a control (without fertilization and ECw 0.5 dS m-1). No effects of the factors evaluated on the gas exchange of beetroots were observed. However, the increase of ECw has negative effects on phytomass and growth of this crop, as the application of bio fertilizer favors some soil chemical characteristics.
