Ecological sustainability, productivity, and sensory quality of coffee fruits are important variables for coffee cultivation in agroforestry systems (AFSs). There is an appreciation of the ecological interactions between agricultural crops and native plants in the AFS. Coffea arabica L. is a shrub with geographic origins in the tropical forests of Africa. Thus, the production of coffee in AFSs can be an interesting alternative. In this study, we present the sensory and chemical profile of coffee grown in three AFSs in the Maciço do Baturité region, Ceará, Brazil and submitted to five types of post-harvest processing. This region has been producing arabica coffee for more than 200 years under forest conditions similar to the ecological characteristics of the geographical center of coffee with shadows produced by native plant species. The coffee fruits were obtained from an AFS with coffee cultivated in the natural/wild system, an AFS in conversion to syntropic, and a conventional AFS. The syntropic AFS and the natural/wild AFS had the highest sensory scores. With the exception of conventional AFS, spontaneous fermentations in covered terrain had higher total scores than fermentations carried out in sealed polyethylene containers. In the sensory panel, the body attribute contributed to the sensory discrimination of fermentation processes by wet and dry methods. Lipids, caffeine, carboxylic acids, and chlorogenic acids were responsible for the chemical differentiation of AFSs Therefore, AFSs and fermentation processes influence the chemical and sensory quality of coffee beans.

This study aimed to propose a model called Two-compartment Logistic-von Bertalanffy (LVB) and to identify among the proposed and Two-compartment Logistic (TL) models the one that has the best goodness of fit to the kinetic curve of cumulative gas production (CGP) of sunflower and corn silages alone and combined using the in vitro semi-automated gas production technique. A random block splitplot experimental design was employed in which the inoculums were the blocks, the incubation times were the split-plots, and the experimental diets were: CS - corn silage, SS - sunflower silage (as singleroughage), and their mixtures, i.e., 340SS (660 g kg-1 corn silage and 340 g kg-1 sunflower silage) and
660SS (340 g kg-1 corn silage and 660 g kg-1 sunflower silage). The parameters were estimated by the least squares method using the iterative Gauss-Newton process in the software R version 3.4.1.vThe criteria adopted were: adjusted coefficient of determination (R2 adj.), residual mean squares (RMS), mean absolute deviation (MAD), Akaike information criterion (AIC), Bayesian information criterion (BIC), and relative efficiency (RE). The TL model had higher R2 adj. values compared to LVB, however, such difference may be considered negligible. The LVB model had RE above one, which indicates it is superior to the TL model, in addition to the lowest RMS, MAD, AIC, and BIC values, The Two compartment Logistic-von Bertalanffy model had the best fit to describe the CGP over time according to the methodology and conditions of the present study.
O objetivo deste trabalho é propor um modelo denominado Logístico-Von Bertalanffy bicompartimental (LVB) e identificar entre os modelos proposto e Logístico bicompartimental (LB), aquele apresenta maior qualidade de ajuste à curva de cinética de produção cumulativa de gases (PCG) das silagens de girassol, de milho e de suas misturas, através da técnica ?in vitro? semiautomática de produção de gases.
O delineamento experimental foi em blocos ao acaso, onde os inóculos equivalem aos blocos, os tempos de incubação às subparcelas, e as dietas experimentais foram: SM - silagem de milho; 340SG - 660 g kg-1 de silagem de milho e 340 g kg-1 de silagem de girassol; 660SG - 340 g kg-1 de silagem de milho e 660 g kg-1 de silagem de girassol e SG - silagem de girassol. Os parâmetros foram estimados pelo método de mínimos quadrados utilizando o processo iterativo de Gauss-Newton, a partir do programa R versão 3.4.1. Os critérios adotados foram: o coeficiente de determinação ajustado (R2adj.), quadrado médio do resíduo (QMR), desvio médio absoluto (DMA), critério de informação de Akaike (AIC), critério
Bayesiano de Schwarz (BIC) e a eficiência relativa (ER). O modelo LB apresentou os maiores valores de R2 adj. comparado ao LVB, porém, essa diferença entre eles pode ser considerada desprezível. O modelo LVB apresentou RE maior que um, indicando superioridade em relação ao LB, além disso, obteve os menores valores de QMR, DMA, AIC e BIC. Dentre os modelos ajustados, o modelo Logístico-Von Bertalanffy bicompartimental apresentou melhor qualidade de ajuste para descrever a PCG ao longo do tempo, de acordo com a metodologia e condições em que foi desenvolvido o presente estudo.
