A produção do cafeeiro (CV. Colômbia) em relação à frequência da fertirrigação e lâminas de irrigação aplicadas.

Abstract

The objective of this work was to evaluate the production of the coffee tree (cv. Colombia) in the productivity, yield and income parameters in different splitting of fertilizer aplications by irrigation water and irrigation blades, in the savannas conditions at Uberlândia-MG. The experimental delineation was the randomized blocks, with the treatments distributed in factorial arrangement 3 x 4, with 4 repetitions, being the factors: three blades of irrigation (80%, 120% and 160% of the water evaporation in the “Class A” tank) and four different times of application of nitrogen and potassium under water irrigation: (F1 - fertirrigation two times per week, F2 – fertirrigation a time per week, F3 - fertirrigation two times per month and F4 - fertirrigation a time per month). The production, the yield and the income were evaluated. There was only significant difference for the production parameter in relation to the irrigation blade factor. For the parameters of yield and income there were no significant differences
