(Universidade Federal de Santa Maria, 2015-09)O objetivo deste trabalho foi comparar a capacidade discriminatória de métodos para seleção e recomendação de clones de cafeeiros da espécie Coffea canephora, considerando a interação genótipos x anos na distribuição da ...
-
(Universidade Federal de Santa Maria, 2015-10)A realização de mais de uma operação da colhedora de café pode aumentar a eficiência de colheita dos frutos, minimizando a quantidade de café remanescente nas plantas e a necessidade de repasse manual. O repasse manual ...
-
(Universidade Federal de Santa Maria, 2015-11)Com o objetivo de avaliar o efeito da consorciação e manejo de Brachiaria decumbens cv. ‘Basilisk’ em cafeeiro (Coffea arabica cv. ‘Catuaí Vermelho’) infestado por Pratylenchus brachyurus (Pb), o presente experimento foi ...
-
(Universidade Federal de Santa Maria, 2016-02)A competitividade no mercado agrícola tem tornado intensa a busca pela redução de custo nos processos de produção, como é o caso da colheita do café (Coffea arabica L.), que tem migrado da colheita manual para a semi ...
-
(Universidade Federal de Santa Maria, 2016-10)Brown eye spot (BE) caused by Cercospora coffeicola is the main disease of coffee crop. A variation in symptoms of BE has been reported in the field, raising suspicion of occurrence of new species. However, information ...
-
(Universidade Federal de Santa Maria, 2017-08)This study aimed to verify if the growth pattern of coffee berries, considering fresh mass accumulation over time, is double sigmoid and to select the most suitable nonlinear model to describe such behavior. Data used ...
-
(Universidade Federal de Santa Maria, 2017-09)Sensory characteristics were evaluated such as aroma, taste, aftertaste, acidity, body, consistency, balance, cleanliness of the cup, sweetness and beverage quality of four coffee cultivars (Catuaí, Caturra, Pache and ...
