Resumo
A cultura do cafeeiro é uma das principais da Bahia e em algumas regiões, como o Planalto de Conquista, é de fundamental importância para o desenvolvimento econômico e social. Condições climáticas desfavoráveis e deficiências identificadas no sistema de produção do café são algumas das causas da baixa produtividade: em média, 12 sc/ha. Uma dessas deficiências é a indefinição da população de plantas por unidade de área, determinada pelo espaçamento e pela densidade de plantio. Objetivando a definição desses fatores de produção para duas cultivares de cafeeiro - Catucaí e Catuaí - um ensaio foi instalado em 1999 na Estação Experimental da EBDA, no município de Barra do Choça. O delineamento experimental utilizado é o de blocos ao acaso em parcela subdividida com 4 repetições e 12 tratamentos. As parcelas são as variedades Catucaí e Catuaí. As subparcelas são as densidades populacionais de plantas, de 2.500 a 20.000 plantas/ha, correspondentes aos espaçamentos de 4,0; 3,0; 2,0; e 1,0 m entre linhas e 1,0; 0,8; e 0,5 m entre plantas. Estão sendo avaliados rendimento, produção por planta, altura de planta, diâmetros do caule e da copa e número de ramos plagiotrópicos. Com os resultados obtidos na primeira safra, pode-se verificar que não houve distinção entre as cultivares Catucaí e Catuaí quanto ao
rendimento médio e à produção por planta. Ocorreu diferença significativa entre os tratamentos, sendo os plantios mais adensados mais produtivos, embora a produção por planta tenha sido reduzida em mais de um terço, quando comparada com os plantios mais largos.
Coffea arabica is one of the main crops in Bahia, especially in some areas like Planalto da Conquista where it has a fundamental importance in the economical and social development. Unfavorable climatic conditions and deficiencies identified in the system of production of this coffee are some causes of the low production, on the average 12 sacks/ha. One of these deficiencies is the non-establishment of the population of plants by a given area, determined by the space and plantation density. With the objective of defining these production factors for two plantations of Coffea arabica "Catucaí" and "Catuaí" cultivars, an experiment was initiated in 1999 at "Estação Experimental do EBDA", in a city called Barra do Choça(BA). The experimental design used was random blocks one. It was done in parcels subdivided into 4 repetitions and 12 treatments. The portions are the following varieties "Catucaí" and "Catuaí". What we called "subparcels" stands for the population densities of the plants, of 2.500 to 20.000 plants/ha, corresponding to the spacing of 4,0m, 3,0m, 2,0m and 1,0m between the lines and 1,0m, 0,8m and 0,5m between the plants. The yield, the production from each plant, the plant height, the stalk and the pantry diameter and number of "plagiotrópicos" branches were evaluated. With the results in the first crop, it could be noticed that there was no distinction between Catucaí and Catuaí relating to the medium revenue and the production of the plant. There was a significant difference between the treatments, though. The closest plantations were more productive, although the production for each plant was reduced about one third when it’s compared to plantations where the plants were kept further from each other.
