“…ey are formed by means of esterification of trans-cinnamic acids, such as caffeic acid, ferulic acid, and p-coumaric acid with quinic acids [19]. During the roast process, they are strongly degraded generating acids, lactones, and volatile compounds such as the phenil, guaiacol, and 4-vinyl guaiacol [20,21], which contribute to the flavor and aroma of coffee, especially for the astringency of the beverage; the proanthocyanidins along with the polyphenols also provide an astringent flavor [22]. Within acceptable limits, chlorogenic acids have a positive effect on the beverage body.…”

Micronutrients perform speci c and essential functions in plant metabolism, and their de ciency may lead to metabolic disturbances that a ect co ee production and quality beverage. In Brazil, the B, Cu, and Zn are the main micronutrients, and these are provided by soil or foliar fertilization, frequently with low recovery e ciency. is work objected verifying the feasibility of supplying of B, Cu, and Zn via insertion of tablets in the orthotropic branch of Co ea arabica, as well as to evaluate the co ee plant response in terms of productivity and quality of the beverage. Adult plants received B, Cu, and Zn, each micronutrient alone or combined with the other two, by foliar fertilization or by tablets inserted in the trunk base. e productivity, cupping quality, and some chemical indicators of beans quality were evaluated in two crop seasons. Boron, copper, and zinc supplied by foliar spray or solid injections in the trunk in uenced the chemical composition and quality of the co ee beans, characterized by the cupping test and the levels of ca eine, trigonelline, sucrose, glucose, arabinose, mannose, 3-ca eoylquinic acid, 5-ca eoylquinic acid, polyphenol oxidase activity, and total phenolic compounds. Copper and zinc were equivalent in either form of supply regarding the production and quality of co ee.

“…Coffee originally came from the deciduous forests in Ethiopia and Sudan, and has been associated with understory conditions. Latin American countries, such as Colombia, Costa Rica, Ecuador, and Guatemala, have been using shading as a technique for a more rational and conservationist use of the soil in coffee areas (Aquino et al, 2008a;Morais et al, 2009), in accordance with the precepts of organic agriculture sustainability.…”

“…The shading technique generates additional income for the farmer and maintains a balanced system by preserving biodiversity, soil, water resources, and carbon (Morais et al, 2009). The use of cover crops is relevant for maintaining and improving the chemical, physical, and biological characteristics of the soil, allowing for the conservation of more balanced environments (Perin et al, 2003;Paciullo et al, 2007).…”

-The objective of this work was to assess the effect of different coffee organic cultivation systems on chemical and biological soil characteristics, in different seasons of the year. The following systems were evaluated: coffee intercropped with one (CJ1), two (CJ2) or three (CJ3) pigeon pea (Cajanus cajan) alleys; coffee planted under full sun (CS); area planted with sweet pepper and snap bean in a conventional tillage system (AC); and secondary forest area (FFR). Row spacing in CJ1, CJ2, CJ3 and CS was 2.0x1.0, 2.8x1.0, 3.6x1.0, and 2.8x1.0 m, respectively. Soil samples were collected at 10-cm depth, during the four seasons of the year. The results were subjected to analysis of variance, principal component analysis, and redundancy analysis. There was an increase in edaphic macrofauna, soil basal respiration, and microbial quotient in the summer. Total macrofauna density was greater in CJ2 followed by CJ3, CS, CJ1, AC and FFR; Coleoptera, Formicidae, and Isoptera were the most abundant groups. There are no significant differences among the areas for soil basal respiration, and the metabolic quotient is higher in CJ1, CJ3, and FFR. Microbial biomass carbon and the contents of K, pH, Ca+Mg, and P show greater values in AC.Index terms: Cajanus cajan, Coffea arabica, edaphic macrofauna, metabolic quotient, shading, soil microbial biomass. Bioindicadores de qualidade do solo em sistemas de cultivo orgânico de caféResumo -O objetivo deste trabalho foi avaliar o efeito de diferentes sistemas de cultivo orgânico do cafeeiro sobre as características químicas e biológicas do solo, em diferentes estações do ano. Foram avaliados os sistemas: consórcio do cafeeiro com uma (CJ1), duas (CJ2) ou três (CJ3) linhas de guandu (Cajanus cajan); plantio do café a pleno sol (CS); área de plantio convencional de pimentão e feijão-vagem (AC); e área de floresta secundária (AFS). O espaçamento entre linhas em CJ1, CJ2, CJ3 e CS foi de 2,0x1,0, 2,8x1,0, 3,6x1,0, e 2,8x1,0 m, respectivamente. O solo foi amostrado na profundidade de 10 cm, nas quatro estações do ano. Os resultados foram submetidos à análise de variância, à análise de componentes principais e à análise de redundância. Houve aumento na macrofauna edáfica, na respiração basal do solo e no quociente microbiano, no verão. A densidade total da macrofauna foi maior em CJ2 seguidos por CJ3, CS, CJ1, AC e FFR; Coleoptera, Formicidae e Isoptera foram os grupos mais abundantes. Não há diferenças significativas entre as áreas quanto a respiração basal do solo, e o quociente metabólico é maior em CJ1, CJ3 e AFS. O carbono da biomassa microbiana e os teores de K, pH, Ca+Mg e P são maiores em AC.Termos para indexação: Cajanus cajan, Coffea arabica, macrofauna edáfica, quociente metabólico, sombreamento, biomassa microbiana do solo.

“…According to Morais et al [26], hydric stress associated with high temperature can quicken cherries maturation. However, Morinigo [27], working in the same site, period, and plots, did not find any difference in soil moisture in 0,0-20 and 0,20-0,40 m depths.…”

Shading coffee trees has gained importance, especially among smallholders, as an option to improve the products' quality, therefore acquiring place at the specialty coffee market, where consumers are willing to give bonus for quality. This work aims to evaluate the influence of shade trees' spatial distribution among coffee trees' agronomic characteristics, yield, and beans and cup quality of shaded coffee trees. The experimental design consisted of completely randomized blocks with six repetitions and four treatments: coffee trees on shade trees planting rows, distant one meter from the trunk; coffee trees on shade trees planting row, distant six meters from the trunk; and coffee plants between the rows of shade trees, parallel to the previous treatments. The parameters analyzed were plant height, canopy diameter, plagiotropic branches' length, yield, coffee fruits' phenological stage, ripe cherries' Brix degree, percentage of black, unripe, and insect damaged beans, bean size, and beverage quality. Shade trees quickened coffee fruits' phenological stage of coffee trees nearest to them. This point also showed the best beverage quality, except for overripe fruits. The remaining parameters evaluated were not affected by shade trees' spatial distribution.
