(Universidade Federal de Santa Maria, 2025)The structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and ... -
(Universidade Federal de Santa Maria, 2024-08-26)With advancements in coffee cultivation, several traits may be considered in selection of plants, which must exhibit a set of favorable characteristics. The outturn index, defined as the relationship between the mass of ...
-
(Universidade Federal de Santa Maria, 2017)The objective of this study was to evaluate the economic benefit of coffee cultivation, with a focus on the distinction between conventional and irrigated coffee production systems. For the development of the study, the ...
-
(Universidade Federal de Santa Maria, 2024-02-23)In Brazil, certain studies have been performed on the exposure to global occupational noise levels when mechanized equipment is used in coffee-growing. However, these did not indicate the behavior within a frequency spectrum ...
-
(Universidade Federal de Santa Maria, 2023)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, 2023-07-17)The research was conducted to test the hypothesis that the inclusion of coffee husk (Coffea sp.) would improve the fermentative characteristics and quality of pearl millet silage (Pennisetumglaucum). Thus, the objective ...
-
(Universidade Federal de Santa Maria, 2023-08-21)The cryopreservation of plant germplasm at ultralow temperatures is an alternative technique for the long-term storage of seeds of the genus Coffea sp. However, for this technique to be successful, cell integrity must be ...

(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 ...
