(Universidade Federal de Santa Maria, 2022-11-28)Genetic variability is the basis for coffee genetic breeding. This study evaluated the potential of leaf anatomy and morpho-agronomic traits in studies of genetic variability in C. canephoracultivars. Ten genotypes were ... -
(Universidade Federal de Santa Maria, 2022-05-11)The determination of nitrogen in plants by techniques that allow a fast diagnosis, based on plant growth characteristics, can be a useful tool for the nutritional management of coffee plants. Thus, this study evaluated ...
-
(Universidade Federal de Santa Maria, 2022-08-29)This study evaluated the level of occupational noise emitted by automotive harvesters during coffee harvest. For the evaluations, three self-propelled harvesters were used: Case-IH® model Coffee Express 200, with cabin; ...
-
(Universidade Federal de Santa Maria, 2022-01-31)The nutritional management of the coffee clonal garden influences the production and physiological quality and seedlings production of vegetative propagules. Thus, this study aimed to analyze the seedlings’ production from ...
-
(Universidade Federal de Santa Maria, 2022-03-14)When modeling growth curves, it should be considered that longitudinal data may show residual autocorrelation, and, if this characteristic is not considered, the results and inferences may be compromised. The Bayesian ...
-
(Universidade Federal de Santa Maria, 2022)This research evaluated the effects of coffee cultivation with two different water regimes associated or not with liming and the presence/absence of brachiaria as intercrop on the activities of the soil enzymes β-glucosidase, ...
-
(Universidade Federal de Santa Maria, 2021)This study evaluated the occupational exposure of workers to heat during manual harvesting of coffee. The case study was conducted between May to August. Occupational heat in coffee plantations was evaluated using the Wet ...
-
(Universidade Federal de Santa Maria, 2021)To investigate the degree of parasitism of two populations of Meloidogyne exigua, the gall index (GI) and the reproduction factor (RF) of M. exigua races 1 (Est E2) and 2 (Est E1) were analyzed in 47 progenies on F3:4 or ...
-
(Universidade Federal de Santa Maria, 2021)The chemical analysis of flowers has been studied for some crops. In coffee trees, the flower tissue analysis could anticipate the nutritional diagnosis. This study aimed to: (i) compare the mineral composition of coffee ...
-
(Universidade Federal de Santa Maria, 2021)The current study determined the factors influencing the perception of tea farmers towards organic tea production in Rulindo District, Rwanda. This study used both qualitative and quantitative data from face to face ...

Coffea canephora breeding: estimated and achieved gains from selection in the Western Amazon, Brazil(Universidade Federal de Santa Maria, 2021)Gain from selection is an important criterion in quantifying the efficiency of breeding programs. This study quantified the selection gain estimated under experimental conditions and realized gain achieved in the field, ...
-
(Universidade Federal de Santa Maria, 2020)The development of Coffea canephora cultivars is based on the characterization of genotype × environment interaction, which is interpreted to quantify the differential behavior of clones at different cultivation sites. The ...
-
(Universidade Federal de Santa Maria, 2019)Coffee crops play an important role in Brazilian agriculture, with a high level of social and economic participation resulting from the jobs created in the supply chain and from the income obtained by producers and the ...
-
(Universidade Federal de Santa Maria, 2019)This study aimed to evaluate the effects of replacing oat hay with coffee husk in the diet of lambs on the intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), ...
-
(Universidade Federal de Santa Maria, 2018)Enzymes play a fundamental role in degradation of molecules during seed germination, development, and deterioration. Endo- β-mannanase is one of the main enzymes responsible for hydrolysis of mannans in the endosperm during ...
-
2- Isopentenyladenine in the induction of direct somatic embryogenesis capacity of Coffea arabica L.(Universidade Federal de Santa Maria, 2018)This study evaluated the effect of different concentrations of 2-isopentenyladenine (2-iP) on the direct somatic embryogenesis capacity of the Mundo Novo cultivar of Coffea arabica. Leaf explants were cultivated with half ...
-
(Universidade Federal de Santa Maria, 2008-09)O estudo da eficiência nutricional de plantas enxertadas de cafeeiro é importante para a seleção de combinações enxerto/porta-enxerto visando desenvolvimento e produção máximos. O presente trabalho teve como objetivo avaliar ...
-
(Universidade Federal de Santa Maria, 2008-07)O objetivo deste estudo foi avaliar as preferências dos consumidores de café da região oeste do Paraná, em relação ao ponto de torra e à granulometria de moagem. Foram realizadas análises sensoriais de preferência e físico- ...
-
(Universidade Federal de Santa Maria, 2008-01)Diferenças na disponibilidade de radiação podem causar modificações na estrutura e função das folhas do cafeeiro, que podem responder de maneira diferencial à radiação por alterações morfológicas, anatômicas, de crescimento ...
-
(Universidade Federal de Santa Maria, 2008-01)O objetivo deste trabalho foi estudar os efeitos das doses de fertilizante de liberação lenta e dois substratos sobre o crescimento e a qualidade das mudas de Coffea arabica L., a fim de gerar parâmetros que permitam a ...
