Production of ‘Isabel’ vine in the function of types and doses of biofertilizer

Abstract

The ‘Isabel’vine is important and social in the agricultural sector, boosting the agribusiness of tropical fruits. Given the challenges faced by the agricultural sector, it is important to seek new cultivation practices, using the organic input as an alternative, because they are efficient and less polluting, and may partially replace synthetic fertilizers. In this context, the objective was to evaluate the application of types and doses of biofertilizer in the production of the Isabel vine, in its first productive cycle. The experiment was conducted in the city of Catolé do Rocha, PB, in randomized blocks, with 40 treatments, in the factorial scheme 5× 8, with four replications, totaling 160 experimental plots. In the present study, 5 types of biofertilizers were studied (B1= based on non-enriched bovine manure, B2= B1+ MB4 rock meal, B3= B2+ legume (Vigna unguiculata L. Walp.), B4= B2+ legume and wood ash) and 8 doses of biofertilizer (D1= 0, D2= 0.35, D3= 0.7, D4= 1.05, D5= 1.4, D6= 1.75, D7= 2.1, and D8= 2.45 L plant-1), applied every 2 months. The interaction of doses and types of enriched biofertilizers had an effect on the bunch mass, bunches mass per plant and berry mass. The productive attributes of the Isabel vine obtained better values with theoptimal doses that varied between 1.40 and 1.55 mL plant-1in types B1, B2, B3and B5.
