“…These high productions confirm that Brazil is the main world producer (Silva et al, 2011). With great emphasis on the Southeast regions, especially the State of Minas Gerais, which is the largest national producer of the grain, having produced in the 2020/2021 harvest about 39,813 thousand bags of processed coffee, equivalent to approximately 84.0% of the national production (CONAB, 2021).…”

The coffee culture has great economic importance on the world stage, especially for Brazil. Considered one of the most traded commodities on the world's trading exchanges. Thus, the main objective of this study was to develop a system based on fuzzy rules to evaluate coffee productivity, using irrigation, soil water deficit and ambient temperature as the main production factors. The research was developed from searches of scientific data on the main variables for coffee production. The work was divided into two stages: the first in the scientific search for data collection and the second in the development of the fuzzy model. With this, it was parameterized that the input variables would be the temperature, the irrigation depth, and the water deficit of the soil and for the output variable the coffee productivity. Based on the model prediction, the fuzzy system showed which variable values are necessary for the best coffee productivity, by a set of rules involving the variation of water deficit (60%), temperature (30°C) and irrigation (300 mm), for a productivity of 24 sc ha-1. The performance of the fuzzy system was tested by comparing it with articles on the subject that relate coffee production with irrigation, water deficit and temperature of the environment and in almost all cases the model was efficient, reinforcing the assessment of the strength of the scheme, the analysis was extended to several scenarios relating the same three input variables.

Genericamente interpretados como corredores com edifícios alinhados em ambos os lados de determinada via, os cânions urbanos constituem uma das principais características morfológicas de cidades contemporâneas com eixos de adensamento atrelados ao sistema de mobilidade urbana, acarretando, muitas vezes, relevantes implicações ambientais adversas ao meio urbanizado. Entendendo o envelopamento vegetal como o revestimento de edificações com superfícies vegetadas, a hipótese da pequisa é de que essa estratégia constitui uma medida viável para políticas públicas voltadas à mitigação desses efeitos. Objetiva-se então analisar o potencial dessa solução para aquela configuração morfológica urbana, apoiando-se no estudo de caso dos setores estruturais de Curitiba, Paraná. A partir da interpretação da estrutura espacial interna de cada trecho e da análise integrada do conjunto, a avaliação do potencial de envelopamento dos edifícios do espaço específico de estudo permite a proposição de Fator de Envelopamento Vegetal (FEV) mínimo de 0,2 para o revestimento edilício e de 0,3 para a obtenção de incentivos indiretos.

Effect of season and irrigation on the chemical composition of Aloysia triphylla essential oil

et al. 2019

Effect of season and irrigation on the chemical composition of Aloysia triphylla essential oil Aloysia triphylla is an aromatic plant used in several industrial sectors, owing to the chemical properties of its essential oil. Biosynthesis of organic compounds is influenced by the growth conditions. As such, temporal and spatial variation affect the chemical composition of essential oils. We hypothesized that: i) the chemical composition of A. triphylla essential oil is influenced by differences in irrigation and season; and ii) the major components of A. triphylla essential oil do not vary between treatment conditions. To test these hypotheses, we determined the chemical composition of A. triphylla essential oil as a function of four seasons crossed with four irrigation levels. A completely randomized experimental design with a randomized block in a 4 × 4 factorial scheme, representing the four seasons of the year (summer, autumn, winter, and spring) and four irrigation levels (50%, 75%, 100%, and 125% of the reference evapotranspiration), was used with four replicates. Our results show that the chemical composition of A. triphylla essential oil varied with the two study factors, of which season was the major factor. The highest concentrations of constituents classified as monoterpene and sesquiterpene were observed in the summer season, and the highest constituents of the other group of compounds were observed in winter. In addition, the major components of the essential oil were α-citral, limonene, and β-citral, and their levels were the highest during winter.
