“…This superiority of the irrigated plants compared to non-irrigated was also found by ROTONDANO et al (2005) in Uberlândia -Minas Gerais State, by BONOMO et al (2008) in Jataí -Goiás State and by LIMA et al (2008) in Lavras -MG, all in Brazil.…”

Irrigation management can be established, considering the soil water potential, as the limiting factor for plant growth, assuming the soil water content between the field capacity and the permanent wilting point as available water for crops. Thus, the aim of this study was to establish the soil water potential interval during four different phenological phases of coffee irrigated by center pivot. The experiment was set at the experimental area of the Engineering Department at the Federal University of Lavras, in Brazil. The coffee variety planted is designated as Rubi, planted 0.8 meters apart, with rows spaced 3.5 meters apart. The treatments corresponded to the water depths applied based on different percentages of Kc and reference evapotranspiration (ET 0 ) values. Sensors were used to measure the soil water potential interval, installed 25 centimeters depth. In order to compare the results, it was considered as the best matric potential the one that was balanced with the soil water content that resulted in the largest coffee productivity. Based on the obtained results, we verified that in the phases of fruit expansion and ripening, the best results were obtained, before the irrigations, when the soil water potential values reached -35 and -38 kPa, respectively. And in the flowering, small green and fruit expansion phases, when the values reached -31 and -32 kPa, respectively.KEY WORDS: irrigated coffee, available water, Coffea arabica L.

“…However, producers adopting circular planting in low latitude and high temperature regions are concerned with solar radiation that according to MATIELLO et al (2005) can cause scorched leaves, dry stems, yield loss and unequal ripening. The correct form of orientation for planting the coffee tree rows should be studied for the best distribution of intercepted radiation on the two sides of the cropping row (BICALHO et al, 2009). LIMA et al (2008 quoted a study carried out in the Minas Gerais triangle where the greatest productivity was obtained in the rows planted in the Northwest-Southeast and North-South directions.…”

“…Ressalta-se que durante o desenvolvimento deste trabalho foram visualizados sintomas de déficit hídrico nas plantas que não receberam irrigação, como murcha e desfolha. Lima et al (2008) visualizaram, em pesquisa realizada com cafeeiro irrigado no sul de Minas Gerais, sintomas de déficit hídrico nas plantas em épocas de veranico ocorridas na estação chuvosa enquanto Fernandes et al (2000) verificaram, na região Planaltina de Goiás, GO, que a supressão da irrigação do cafeeiro no período chuvoso provocou redução de até 32% na produção devido à incidência de veranicos e à má distribuição de chuvas.…”

RESUMOPropôs, neste trabalho, avaliar os efeitos da irrigação e a aplicação do fertilizante Alfertil ® sobre a produtividade e rendimento do cafeeiro. O delineamento estatístico utilizado foi o de blocos casualizados, com parcelas subdivididas contendo quatro repetições. As parcelas receberam tratamentos constituídos de quatro lâminas de irrigação calculadas com base em percentagens de evaporação do tanque Classe A (ECA) ou seja: L 0 = 0 (Testemunha); L 40 = 40%ECA; L 80 = 80%ECA e L 120 = 120%ECA e as subparcelas receberam os tratamentos de adubação constituídos de três formas de aplicação de Alfertil ® , sendo: A 0 = Testemunha (S/Alfertil ® ); A f = via foliar (Alfertil ® na forma líquida na concentração de 5% peso/peso) e A s = via solo (100 g cova -1 planta -1 na forma pó). Verificou-se que a produtividade do cafeeiro foi influenciada pelos tratamentos de irrigação e formas de aplicação de Alfertil ® enquanto somente as diferentes lâminas de irrigação influenciaram o rendimento do cafeeiro. As lâminas de irrigação que maximizam a produtividade e o rendimento do cafeeiro foram as estimadas em 60,08 e 70,20% da ECA, respectivamente, e as plantas adubadas com Alfertil ® via foliar ou solo promoveram aumento na produtividade do cafeeiro.

The statistical design used was in randomized blocks, with subdivided plots and four replications. The coffee plants received four irrigation levels: L 0 = 0 (not irrigated); L 40 = 40% Evaporation of Class A Pan (ECA); L 80 = 80% ECA; and L 120 = 120% ECA. Coffee plants were fertilized with: A 0 = 0 kg ha -1 (no fertilizer); A f = Alfertil ® applied by foliar application by a 5% solution; and A s = Alfertil ® applied in the soil surface with 100 g plant -1 . The results show that the coffee productivity was influenced by irrigation and Alfertil ® fertilization. However, only the different irrigation levels influenced significantly the yield of coffee crop. Irrigation levels that maximized productivity and yield of the plant was estimated at 60.08 and 70.20% ECA, respectively, and the plants fertilized with Alfertil ® either foliar or soil application enhanced the productivity of coffee crop.
