“…Similar results were obtained by Malta et al (2008), who verified the superiority of coffee beverages with the use of bovine manure alone or associated with coffee husks and green manure in coffee plantations in the second year of conversion in relation to conventional management, particularly in terms of sweetness, body and after taste.…”

The use of management practices that reduce the application of phytosanitary products and guarantee sustainability to the production process has been increasingly used in coffee farming. The objective of this work was to evaluate the vegetative, productive and nutritional parameters of coffee plants as a function of management systems. The experiment was set in 2018 in Monte Carmelo, Minas Gerais. The experimental design was in randomized blocks with four treatments and five blocks. The treatments were composed of doses of organic compost applied in topdressing: (T1): 150 g plant-1 (1.7 t ha-1); (T2): 300 g plant-1 (3.4 t ha-1); T3: 500 g plant-1 (5.7 t ha-1); and T4 (control: standard management of the farm). The conventional management provided an increase in the number of internodes in the plagiotropic branch of the coffee tree and in the productivity of the first crop of the plantation. The management systems did not influence the format and size of the coffee beans. The use of organic fertilization and absence of phytosanitary products allowed the production of specialty coffees, besides accelerating the maturation process of the fruits. The management with organic fertilization was efficient in keeping the pH, organic matter, base saturation, effective CEC, phosphorus, sulfur, calcium, copper, iron, manganese and zinc levels in the soil at satisfactory levels. The foliar levels of phosphorus, potassium, sulfur, boron and copper were satisfactory for the crop and did not differ between the management systems adopted in the field.

“…O sistema de produção adotado também pode interferir na qualidade do café. De acordo com Malta (2008), no segundo ano de conversão de lavouras convencionais para orgânicas foi observado efeitos significativos de práticas de adubação orgânica (com esterco bovino isolado ou associado com casca de café) e adubação verde sobre as qualidades sensoriais do café arábica. Batista (2007) afirma que é necessário conhecer os pontos críticos da colheita e póscolheita para conseguir minimizar a infestação de fungos nos grãos de café, que depreciam a qualidade da bebida por meio de fermentações indesejáveis ou são produtores de micotoxinas, notadamente a ocratoxina A. O autor ainda afirma, baseado em seus resultados, que os pontos críticos a serem combatidos são: a secagem em terreiros de terra, a colheita por meio de varrição e a secagem de café mistura (grãos cereja maduros, verdes e boia).…”

“…Furthermore, the drier climate in the months of August and September 2009 caused premature maturation of the beans (harvest in March and April 2010), further compromising the grain formation process, evidenced by the low yield achieved in 2010. In the literature, there are contradictory reports of the effect of organic fertilization on the productivity of coffee trees, e.g., Malta et al (2007) observed increase from 33 to 40.8 bg ha -1 with pigeon pea, as well as observed by Araujo et al (2014) with the jack bean. Theodoro, Mendes and Guimarães (2009) verified that coffee productivity was not influenced by applying this legume.…”

ABSTRACT:The adequate supply of nitrogen to coffee plantation is one of the main challenges of organic agriculture. The aim of the present study was to evaluate the effect of organic fertilization with two legume species in different intercropping periods on nitrogen nutrition, initial growth and productivity of coffee plantation. The experimental design was in randomized blocks, in 2x4 split-plot factorial design, being that the plot consisted of two intercrops (coffee+jack bean and coffee+hyacinth bean) and the four intercropping periods (30, 60, 90 and 120 days after sowing of the legume), and the subplot by 50% and 100% of fertilization for the coffee plantation. The increase in the intercropping period between legumes and coffee plantation favored a greater increase in height and node number of coffee trees, besides showing higher heights when fertilized with 50% of the recommended dose and intercropped with hyacinth bean. The intercropping with the hyacinth bean resulted in a larger crown diameter of coffee trees in 2010 and a larger diameter accumulated in the two evaluated years. Higher N contents were found in coffee trees fertilized with 100% of the recommended dose. The legumes supplied the nutritional requirements of the coffee harvest fertilized with 50% of the dose. The bean yield of the processed coffee is not affected by the intercropping with the green manures of jack bean or hyacinth bean.Index terms: Coffea arabica cv. Oeiras, Canavalia ensiformis, Dolichos lablab, nitrogen cycling, organic fertilization. PERÍODO DE CONSORCIAÇÃO ENTRE ESPÉCIES DE ADUBOS VERDES E CAFEEIROS ADUBADOS ORGANICAMENTERESUMO: O suprimento adequado de nitrogênio aos cafeeiros é um dos principais desafios da agricultura orgânica. O trabalho objetivou avaliar o efeito da adubação orgânica com duas espécies de leguminosas em diferentes períodos de consorciação sobre a nutrição nitrogenada, o crescimento e a produtividade iniciais de cafeeiros. O delineamento foi em blocos casualizados, em esquema fatorial (2x4) com parcela subdividida, sendo a parcela constituída por dois consórcios entre cafeeiros e leguminosas (café+feijão-de-porco e café+lablabe) e os 4 períodos de consorciação (30, 60, 90 e 120 dias após a semeadura da leguminosa), e a subparcela por 50% e 100% da adubação para o cafeeiro. O aumento do período de consorciação entre leguminosas e cafeeiros favoreceu um maior incremento em altura e do número de nós dos cafeeiros, e estes apresentaram maiores alturas quando fertilizados com 50% da dose recomendada e consorciados com lablabe. A consorciação com a lablabe resultou em maior diâmetro de copa dos cafeeiros em 2010 e maior diâmetro acumulado nos dois anos avaliados. Maiores teores de N foram encontrados nos cafeeiros adubados com 100% da dose recomendada. As leguminosas complementaram e supriram as necessidades nutricionais exigidas na colheita do café adubado com 50% da dose. O rendimento de grão do cafeeiro beneficiado não é prejudicado pelo consórcio com os adubos verdes feijão-de-porco ou lablabe.Termos pa...
