Item Nutrition and growth of the conilon coffee after application of treated wastewater(Universidade Federal Rural de Pernambuco, 2013-01) Gonçalves, Ivo Z.; Garcia, Giovanni de O.; Rigo, Michelle M.; Reis, Edvaldo F. dos; Tomaz, Marcelo A.The use of domestic wastewater in agriculture reduces the production cost due to the concentrations of nutrients for plants, besides water saving and reduction of environmental impact caused by launching in the water bodies, thus its use is becoming increasingly common in agricultural production. The objective of this study was to evaluate the nutrition and initial growth of the Conilon coffee after application of domestic wastewater. The experiment was conducted in a 13x4 split-plot design, where main plots consisted of 13 clones and four depths of irrigation in sub-plots, being three depths of treated wastewater equivalent to one third, two third and 100% of the crop water demand, and a control irrigated with supply water, in a completely randomized design with three repetitions. The results showed that application of the effluent was not sufficient to meet the nutritional needs (N, P and K) for nitrogen and potassium of the Conilon coffee, however, the increment in applied depths caused higher uptake of nitrogen and potassium resulting in best initial growth of the crop.
