Abstract

The amount of nutrients present in husks and beans from Conilon coffee fruits directly influence the crop nutritional management, as well as its use as a complement to conventional fertilization. The present study aimed to quantify the concentration and accumulation of nutrients in husks, beans and whole fruit in irrigated and non-irrigated plants from the cropped genotype C. canephora cv. Conilon Clone 02, from clonal variety EMCAPA 8111. The experiment consisted of two treatments (irrigated and non-irrigated) in a completely randomized design with 28 replicates under field conditions, in southern Bahia, Brazil. During harvesting stage, 50 fruits per plant, in two consecutive harvests, were collected to quantify the dry matter and accumulation of nutrients in the husks, beans and fruits. The fruits from irrigated coffee plants showed higher N, P, K, Ca, Mg, Cu and Mn accumulation than non-irrigated plants. The huskand beans from irrigated coffee plants showed higher Ca, Zn and Cu and N, P, Ca, Mg, S, Cu and Mn accumulation, respectively, than non-irrigated coffee. Regarding the nutrient accumulation, K followed by N, and Ca were the most represented macronutrients in coffee husk. N followed by K and P, and N followed by K and Ca were the most represented macronutrients in beans and fruit, respectively. Fe and B were the micronutrients found in higher contents in husk, beans and fruits from Conilon coffee.
