Development and production of fertigated coffee trees in the west region of Bahia, Brazil

This work was to evaluate the effects of different doses and fertigation parceling on the production and development of irrigated coffee drip in the Western Bahia region. He carried out the work on the farm White River Café, located in Barreiras - BA in coffee adults, approximately 3.5 years of age, Catuaí IAC 144. The experiment was conducted in a factorial 3 x 3, three levels of nitrogen and potassium fertilization (900/800, 600/500 and 300/250 kg ha-1 yr-1 N and K2O) in 3 monthly installments of fertigation (2, 4 and 8 times). The variables in the experiment were: productivity, growth, yield and sieve. The doses of 600/500 and 900/800 kg ha-1 yr-1 N / K2O, the highest yield of the coffee. The installments of fertigation at two and eight times per month were higher in productivity. A higher effect of splitting the fertigation, on the effect of N and K2O in the coffee development variables (crown diameter and plant height). There was no effect of dose and fertigation parceling on rating sieve of coffee beans.The aim in the present study was to evaluate the effects of different split fertigation and doses on the development and production of drip irrigated coffee in the western region of the state of Bahia, Brazil. The study was performed at the Café do Rio Branco Farm, in Barreiras, BA, Brazil, in adult coffee trees aged approximately 3.5 years from the variety Catuaí IAC 144. A 3 x 3 factorial design was adopted, with three levels of nitrogen and potassium fertilization (900/800, 600/500 and 300/250 kg ha-1 year-1 N and K2O) in three monthly split fertigation (two, four and eight times). Stem and crown growth, productivity, yield and sieve were evaluated. The doses of 600/500 and 900/800 kg ha-1 year-1 N/K2O and the splits in two and eight times provided the highest productivities of coffee. A higher split fertigation was observed on the effect of N and K2O doses in coffee development variables (crown diameter and plant height). There was no effect of split fertigation and doses in the classification by sieves of coffee beans
