DESENVOLVIMENTO DA CULTURA E PRESENÇA DE E. COLI NA SALSA IRRIGADA COM ÁGUA RESIDUÁRIA TRATADA POR RADIAÇÃO SOLAR

英语. The objective of this work was to evaluate the influence of solar radiation treated by solar radiation (ARD-TRS) on the development of parsley, in addition to verify and quantify the presence of Escherichia coli in the culture. The experiment was carried out at FCA/UNESP in the city of Botucatu-São Paulo, which consisted in the application of different percentages (0, 25, 50, 75 and 100%) of ARD-TRS in the total irrigation depth. The results were satisfactory, since in general there was an increase in the values ​​of plant height, number of stems, diameter of the largest stem, diameter of the clump and mass of fresh and dry matter, observing significant differences as a function of the percentage of ARD -TRS in the total irrigation blade. Thus, the use of different percentages of ARD-TRS in the total irrigation depth influenced positively the development of the studied culture with E. coli population in the irrigation water <100 NMP 100 mL-1 and in the cultures ≤ 1,000 NMP 100 mL -1

O experimento foi realizado na FCA/UNESP no município de Botucatu - São Paulo, o qual consistiu na aplicação de diferentes porcentagens (0, 25, 50, 75 e 100%) de ARD-TRS na lâmina total de irrigação. Os resultados obtidos foram satisfatórios, visto que no geral houve um aumento nos valores de altura da planta, número de talos, diâmetro do maior talo, diâmetro da touceira e massa da matéria fresca e seca, observando-se diferenças significativas em função da porcentagem de ARD-TRS na lâmina total de irrigação. Assim conclui-se que, a utilização de diferentes porcentagens de ARD-TRS na lâmina total de irrigação influenciou positivamente no desenvolvimento da cultura estudada, apresentando uma população de E. coli na água de irrigação < 100 NMP 100 mL-1 e nas culturas ≤ 1.000 NMP 100 mL-1.   Palavras-chave: reuso da água, SODIS, Petroselinum Crispum, coliformes, produtividade.   SALES, M.

COLI IN PARSLEY IRRIGATED WITH DOMESTIC WASTE WATER TREATED WITH SOLAR RADIATION     2 ABSTRACT   The objective of this study was to evaluate the influence of solar-treated domestic wastewater (ARD-TRS) on the development of parsley (Portuguese coarse), and to verify and quantify the presence of Escherichia coli in the crop. The experiment, carried out at FCA / UNESP, in Botucatu - São Paulo, consisted of the application of different percentages (0, 25, 50, 75 and 100%) of ARD-TRS in the total irrigation depth. The results obtained were satisfactory, since in general there was an increase in  values ​​of plant height, number of stalks, diameter of the largest stalk, clump diameter and mass of fresh and dry matter, and significant differences were observed as function of the percent of ARD-TRS in the total irrigation depth. Thus, it was concluded that the use of different percentages of ARD-TRS in the total irrigation depth had a positive influence on the development of the studied culture, presenting a population of E. coli in irrigation water <100 NMP 100 mL-1 and in cultures ≤ 1,000 NMP 100 mL -1.   Keywords: water reuse, SODIS, Petroselinum crispum, coliforms, productivity.
