Abstract

The objective of this study was to analyze the spatial variability of soil chemical attributes under pasture, as well as lime and fertilizer recommendations based on the interpretation of soil chemical analysis from two sampling methods: conventional and systematic depths of 0 to 10 and 10 to 20 cm. The study was conducted at IFES-campus Alegre-ES. Data analysis was performed using descriptive statistics and geostatistics. Results indicate that the spatial method enabled the identification of deficit areas and excessive liming and fertilization, which could not be defined by the conventional method. Objetivou-se neste trabalho analisar a variabilidade espacial de atributos químicos de solo sob pastagem e as recomendações de calagem e adubação baseadas na interpretação das análises químicas de solo provenientes de dois métodos de amostragem: convencional e sistemático nas profundidades de 0 a 10 e 10 a 20 cm. O estudo foi realizado no Ifes campus de Alegre-ES. A análise dos dados foi realizada por meio da estatística descritiva e da geoestatística. Os resultados indicaram que o método espacial possibilitou identificar zonas de deficit e excesso de recomendação de calagem e adubação, que não poderiam ser definidas com o método convencional.

Abstract

A área foliar é uma das mais importantes medidas de avaliação do crescimento vegetativo; sendo assim, o conhecimento sobre tal aspecto permite estimar a perda de água por transpiração, devido às folhas serem os principais órgãos responsáveis pelas trocas gasosas entre a planta e o ambiente, tornando-se importante o seu estudo. Dessa forma, objetivou-se com a realização deste trabalho testar e obter o melhor modelo matemático para estimativa da área foliar da mangueira (Mangifera indica L.) cv. Haden em função das suas dimensões alométricas. Utilizou-se um pomar localizado na propriedade São Domingos, no município de Alegre, sul do Estado do Espírito Santo, onde foram coletadas 80 folhas de 20 mangueiras em outubro de 2013. As regressões foram determinadas considerando-se a área foliar real (AFR) como variável dependente, e o comprimento (C), a largura (L) e o produto das dimensões lineares (C x L) de cada folha, como variáveis independentes. Com base nos resultados obtidos, concluiu-se que a equação polinomial y= -0,0001x²+0,6934x+4,7677 foi o melhor modelo matemático para estimar a área foliar da mangueira, com R² de 0,97. Os modelos que utilizam C x L são os mais adequados para estimar a área das folhas da mangueira, uma vez que apresentam maior correlação.

Abstract

When it comes to the sensory analysis of specialty coffees, it is necessary to discuss the protocol of tests of the Specialty Coffee Association (SCA) and the formation of Q-Graders as reliable parameters in the sensory analysis. However, the training of these Q-Graders and the use of the SCA protocol has generated discussions in the scientific community and demonstrated the importance of talking about the level of professional precision as well as the use of the protocol. This study sought to understand the relation of accuracy and efficiency of the Q-Graders and protocol in the sensory analysis of coffees. Three experiments were carried out to evaluate and test the hypotheses regarding the level of precision in relation to the shift, the number of samples and the judgment abilities of Q-Graders due to the quality of the specialty coffee and nonspecialty coffee. These three experiments were performed by seven Q-Graders in an isolated environment during three consecutive days with 137 specialty coffee samples and 7 nonspecialty coffee samples as defined by the SCA. The results indicate that the Q-Graders present high precision when evaluating excellent and outstanding coffees, as defined by the SCA. In addition, the effect of the shift did not exert fatigue on the Q-Graders. However, evaluation errors were made by the Q-Graders on very good coffee (77.00-80.00 points), which are considered as nonspecialty by the SCA, thus allowing a more in-depth discussion on what would be the boundary between a specialty and nonspecialty coffee. PRACTICAL APPLICATIONS: The article deals with the sensory evaluation process of coffees, and it has great importance to teaching and research institutions in Brazil, the largest producer, largest exporter and the country with the highest concentration of coffee scholars in the world. The article focuses on a new approach and a new way of looking at the sensory evaluation process of coffees, using the methodology of the Specialty Coffee Association to analyze the accuracy and efficiency of the Q-Graders., (© 2019 Wiley Periodicals, Inc.)
