RESUMOConduziu-se este trabalho com o objetivo de estudar o efeito do fungo Trichoderma harzianum como promotor de crescimento de sementes de milho tratadas com diferentes fungicidas. O experimento foi realizado em vasos em casa-devegetação, adotando o delineamento experimental inteiramente casualizado em esquema fatorial (3x2), utilizando os tratamentos com fungicidas: Captan®, Maxim® e testemunha e inoculação (com e sem inóculo) em quatro repetições. As características agronômicas avaliadas foram: altura de planta, peso da matéria seca da parte aérea e de raízes e também a técnica de isolamento do fungo nas raízes aos 45 dias após semeadura. Observou-se diferença significativa somente para o fator inóculo na característica peso de matéria seca de raízes. Pelos resultados obtidos, verificou-se que o fungo Trichoderma harzianum estimulou maior acúmulo de matéria seca nas raízes das plantas de milho e também estava presente nas raízes das plantas oriundas de sementes inoculadas, independentemente do tratamento fungicida das sementes. Termos para indexação:Trichoderma harzianum, promotor, crescimento, milho. ABSTRACTThe objective of this work was to study the effect of the fungus Trichoderma harzianum as a growth promoter on the corn seeds treated with different fungicides. This experiment was carried out in pots in a greenhouse by adopting the experimental completely randomized design in (3 X 2) factorial scheme, by utilizing the treatments with fungicides: Captan®, Maximim® and control and inoculation (with and without an inoculum) with four replicates. The agronomic characteristics evaluated were: plant height, shoot and root dry matter weight and also the inoculum isolation technique on the rots after sowing. Significant differences were found only for the factor inoculum in the characteristic root dry matter weight. The results obtained revealed that the fungus Trichoderma harzianum stimulated greatest dry matter accumulation in the roots of corn plants and also it was present in the roots of plants from inoculated seeds regardless of the treatment of the seeds with fungicides.

Osmotic dehydration (OD) is useful for the enrichment of mangos with interesting solutes. Isomaltulose has healthier properties than sucrose and its use is still scarce in OD processes. The OD of mangos with isomaltulose and sucrose was evaluated, and the effect of solute concentrations (25%, 30%, 35%) and temperatures (25, 35, 45°C) was estimated by multilevel statistical analysis in order to find the best conditions for a greater water loss (WL) and solid gain (SG). In sucrose OD, the highest concentration (35%) had the greatest effect than the temperature for WL and SG. For isomaltulose OD, the concentration provided greater WL and SG, but the effect of temperature was slightly more expressive for SG than WL. The maximum working conditions (35% of isomaltulose or sucrose and 45°C) promoted greater WL and SG for both carbohydrates, and with the OD it was possible to enrich mango with isomaltulose by taking advantage of the osmotic gradient, getting an osmodehydrated product with low glycemic and isulinemic indexes.Novelty impact statement: Through the osmotic dehydration, it is possible to enrich mango samples with isomaltulose due to its healthy attributes. Instead, a traditional statistical analysis, the multilevel statistical modeling was applied, which was suitable for evidence that the highest solute concentration and temperature conditions promoted the greatest water loss and solid gain, favoring the enrichment process.

The aim of this study was to evaluate the effects of nitrogen fertilization on yield parameters of the maize crop in season and off-season, originated from the seed inoculated with Trichoderma harzianum or treated with chemical fungicides. The experiment was installed in RBD using subdivided plots. The factor of the plots was attributed to the application of nitrogen doses in cover (0, 60, 90 and 120 kg ha-1). The subplot was characterized by the presence and absence of application of the fungicides Captan ® and Maxim ® and the presence and absence of inoculation with T. harzianum seed. The experimental design used in the off season was the same used in the season, changing only the factorial in the subplot. There were differences in the DKB747 hybrid yield through the application of nitrogen during the season. In off-season there were differences of the nitrogen doses in the characteristics of plant height and grain weight, because the fungicide factor altered the grain weight. As for the AG7575 hybrid, there was no effect of the nitrogen doses on yield and grain weight; the fungicide factor altered the yield characteristics, while the inoculum factor only changed the yield factor during the season. In general, the parameters of maize crop production are enhanced with inoculation of the seeds with T. harzianum. It is not recommended to use nitrogen doses above of the recommended for maximum yield potential of the hybrid.

Grain storage has as its central objective to stock the grain, giving the producer the advantage of distributing it at the best time, thus creating a favorable and profitable market logistics. The state of Mato Grosso is the country's leader in grain production, however its competitiveness vis-à-vis the rest of the country is historically affected by the many logistical bottlenecks still present, including storage, which for years has been one of the main competitive disadvantages. Given this, data were collected based on research on grain production in the state of Mato Grosso in the IBGE and CONAB databases, with the objective of making an analysis on the current static storage capacity of grain in the state of Mato Grosso. In the year 2019, the static storage capacity is 37.808.087 tons showing a deficit of 29.565.71 tons of grains, so that the mesoregions of North and Southeast Mato Grosso lead with the largest static capacity, but still unable to meet demand.
