Produção de cenoura associada a substratos, irrigada com efluente agroindustrial.

Abstract

This study was conducted in the period May to September 2015, the Federal Institute of Paraíba IFPB - Campus de Sousa, located in the Irrigated Perimeter of São Gonçalo, in order to evaluate the productivity and physical-chemical and microbiological quality of carrot irrigated with wastewater agribusiness grown in pots, soil (sand, clay) as well as in soil added to substrates (manure cattle and sheep dung). The experimental design was completely randomized (DIC), with treatments arranged five types of wastewater and two different substrates (manure and sheep manure) with four replications totaling 40 experimental plots. The evaluated characteristics were: The physicochemical and microbiological quality of the raw wastewater and diluted; Physical and chemical characteristics of the soil before and after the experiment; Plant height; fresh and shoot dry; transverse and longitudinal diameter of the root; evaluation of the tubercle, as the physical, chemical, microbiological parameters. It has been shown that it is possible to produce vegetables with water reuse, emerging as an economically viable alternative, a condition that allows you to save drinking water, allowing food production, reducing the high consumption of drinking water, therefore waste. Smaller accumulations of MFPA were found in treatments with 100% and 25% dilutions AR AR roots grown with cattle manure. As also found smaller amounts of DMAP treatments 100% AR and 25% AR manures cattle and sheep. Therefore, the use of wastewater and its different dilutions added to manure cattle and sheep were effective in carrot production of cultivar Alvorada developed in this experiment.
