The storage of agricultural products is of great importance in maintaining product quality between harvest and commercialization. The use of numerical and computational techniques, such as the finite element method (FEM) and computational fluid dynamics (CFD), allows the analysis and simulation of systems that involve heat transfer, as is the case of grain storage. A computational model based on these techniques that satisfactorily represents a real system was used to test and to analyze decision alternatives without the need for real experimentation. In this study, we sought to study the behavior of the temperature of a mass of stored mocha coffee beans by using computational techniques, as requested by the private sector. The coffee was stored for 6 months in two types of environments: a cooled environment between 15 and 18 °C by using an air temperature control equipment used for artificial cooling and a natural environment. A computational model was developed to simulate the heat transfer process for both types of storage. In the comparison of the temperature distribution during storage from simulation results and for experimental results, an overall mean relative error of 2.34% was obtained for coffee stored in a natural environment, and that of 5.74% was obtained for coffee stored in a cooled environment. |

Abstract: Since the 2011/2012 crop season, Embrapa Agrosilvopastoral in Sinop/MT has conducted na experiment of crop-livestock-forest integration, consisting of 10 treatments. The objective of this work was to monitor the incidence and severity of diseases in soybean and corn crops. The treatments studied were: LAV (soybean crop followed by corn + brachiaria), ILPF1 (crop-livestock-forest integration, crop rotation with livestock every 2 years); ILPF2 (crop-livestock-forest integration, with crop and animal entry after the corn harvest, every year); ILP (crop-livestock integration, crop and rotation with livestock every 2 years) and ILF (crop-forest integration). A randomized complete block design was used, with 4 replications. Analysis of variance and the means were compared using the Tukey test at 5% probability. In the soybean crop, in the 2011/2012 and 2012/2013 harvests, there were no diseases. In subsequent harvests, the incidence of target spot was always observed in the R5.1 phase. In the corn crop, in the years 2014, 2016 and 2019 the incidence of diseases was not observed. Bipolar spot was observed in 2017 and cercosporiosis was observed in the years 2015, 2017, 2018 and 2020. In both cultures, the incidence of diseases did not differ between treatments. |
