RESUMO:

Beetroot (Beta vulgaris L.) is a tuber with a sweet taste widely used in Brazilian cuisine that is pleasant to the palate and carries a high level of antioxidant substances. The crop has an annual production of around 300 thousand tons. In the Northeast region, beetroot production is not very significant, and there is not enough production to meet domestic market demand. The present study was developed with the objective of evaluating the application of the biofertilizer, Agrobio ®, in the development and production of beetroot in the Northern Coast of Bahia in an agroecological production system free from pesticides and soluble fertilizers. Agrobio® is produced from aerobic digestion of organic substrates (fresh bovine manure, urine, whey and others) by microorganisms such as fungi and bacteria. The aerobic process lasts on average 56 days and during this period the must is supplemented, periodically, by the addition of macro and micronutrients. Two applications were performed on the seedlings and / or two or four applications after transplanting to the field. Thirty day seedlings treated with biofertilizer presented height and number of leaves 74 and 45% higher than the control, respectively and in terms of leaf area the application of Agrobio® was able to multiply by about eight times in comparison to the control. At the end of 60 days in the field, the best yields were obtained using two applications in the seedling phase and four applications after transplanting (7, 15, 30 and 60 days), corresponding to increases around 400% in relation to the control. Agrobio® application only during seedling phase showed increases of 300% in relation to the control, not differing from the treatment in the seedlings followed by two applications after transplanting (15 and 30 days), while the application response in plants treated just after transplanting was significantly lower, about 200%. The application of Agrobio presented yield in the order of 120 T ha-1 considering a population density of 300,000 ha-1 plants. The incidence of nematodes and contamination by Salmonella and fecal coliforms were also determined. The results indicate that the use of Agrobio® contributes effectively to beetroot cultivation under an agroecological manegement.
