Abstract

The study of the reuse of water is very important nowadays, both in the environmental area, due to the recycling of nutrients and providing a high concentration of essential nutrients for plants. Objective: To verify that the irrigation with treated sewage influences increasing the availability of nutrients in the soil along the groove and this factor will influence significantly the productivity of beans (Phaseolus vulgaris L.). Methods: The experiment will be conducted in a randomized block design where they will be tested five conventionally applied fertilizer levels (100, 75, 50, 25, 0%) with 4 replicates totaling 20 plots 10 meters long. To assess the establishment of the right nutrients groove irrigated with treated sewage will be held from soil samples collected from beginning to end of the groove with a sample spacing of five meters. All samples and soil analysis will be made to the depth of 0 to 20 cm and at different times: at the beginning - soon after planting at 60 DAP (days after planting) and at 120 DAP (or late in the cycle). During the development of culture will be evaluated several variables, according to the physiological state of the culture, among these: plant height, number of pods, fresh and dry weight of plants, number of grains per plant.(AU)
