Qualidade pós-colheita de beterraba submetida à adubação com biofertilizante fermentado.

Abstract

The beet cultivation with biofertilizer consists of a potential alternative to production in family scale, if necessary, but assess the quality of production. Thus aimed to evaluate the beet postharvest quality will undergo fertilization with fermented biofertilizer. The experiment was conducted in the experimental area at the Centre for Science and Agrifood Technology, Federal University of Campina Grande, Campus de Pombal-PB, during the period September to December 2013 in soil classified as Red-Yellow Cambic Argisol. The experimental design was completely randomized. The treatments were the application of two times (20 and 40 days of fermentation biofertilizer) with three replications. Six tubers per plot were used, selected according to uniform size. The biofertilizer fermentation time did not affect the physical and chemical characteristics evaluated, the exception of vitamin C and phenolic content which were higher biofertlizante fermented for up to 40 days and H+ ions up to 20 days of fermentation. The use of new biofertilizer formulations will be important in future studies to further elucidate the influence of this fertilization model on post-harvest beet quality.
