SUMMARY:

Agrobio is a biofertilizer produced from the aerobic fermentation of fresh bovine manure, water, molasses and mineral salts. It has a nutritional effect and promotes phytosanitary control in different cultures. This work evaluated the effect of the biofertilizer Agrobio on the development of Arabica coffee seedlings cultivar Arara, in the city of Andradas-MG. The experimental design was in randomized blocks, with five treatments and four replications. Each plot consisted of 16 seedlings, the 4 central seedlings being used for the evaluations. The treatments differed by the concentrations of the biofertilizer sprayed at 0%, 2%, 4%, 6% and 8%. The evaluated variables were: seedling height, stem diameter, number of leaves, fresh leaf weight, stem and root and dry leaf weight, stem and root. The final incidence of cercosporiosis, caused by the fungus Cercospora coffeicola, was also evaluated. The treatments were carried out from the appearance of the first pair of leaves and were reapplied fortnightly, until the seedlings reached the field point. The assumptions for carrying out the analysis of variance were tested and, after met and when there was significance by the F test between the Agrobio doses by the analysis of variance, regression models were adjusted for the same considering a 5% probability of significance. It was found that the effect of the doses of Agrobio on the variables height and incidence of cercosporiosis was quadratic positive with a maximum point of 161.5 mm in height and 32.5% of leaves with cercosporisis. In the variables Stem Diameter, Fresh Root Weight, Fresh Stem Weight, Dry Root Weight and Dry Stem Weight, the behavior was linearly increasing. Only the Number of Leaves, Fresh Leaf Weight and Dry Leaf Weight variables did not show significant results between the doses of the biofertilizer Agrobio.
