Abstract

ResumoObjetivou-se, com este trabalho, avaliar o efeito de diferentes concentrações de sais e efluente tratado na água de irrigação durante o crescimento da alface crespa de (Lactuca sativa L. Growth of curly lettuce irrigated with treated wastewater and saline water at different concentrations in greenhouse AbstractThe objective of this study was to evaluate the effect of different concentrations of salts and treated effluent in irrigation water during the growth of curly lettuce (Lactuca sativa L). The experiment was conducted in a greenhouse of the Faculty of Technology FATEC Cariri belonging to the Institute Technological Education Center -CENTEC, using a completely randomized design with six treatments and five replications being: EH1 (100% water supply) , EH2 (80% + 20% saline water from the treated effluent), EH3 (50% + 50% of treated effluent water supply), EH4 (20% brine and 80% of treated effluent) EH5 (100 % of treated effluent) and EH6 (100% salt water). It was observed that there was no significant effect relating to the treated effluent concentrations and saline water in the leaves of many variables, growth rate relative and absolute. In relation to collection time was no significant effect on all variables; height, number of leaves, growth rate relative and absolute. If there is no interaction between the two factors. Treatment with 20% A.S.+ 80% A.R%; provided better performance in the studied variables and the treatment had lower performance was treatment with 100% water supply.
