Resumo:
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.
