- ItemConstrução de um veículo autônomo para aplicação de produtos fitossanitário(Universidade Federal de Mato Grosso, 2017-03-10) Rezende, Pablo Franco de; Viliotti, Carlos Alberto; 081.862.308-07; http://lattes.cnpq.br/1680184849424627; Viliotti, Carlos Alberto; 081.862.308-07; http://lattes.cnpq.br/1680184849424627; Mion, Renildo Luiz; 034.525.757-05; http://lattes.cnpq.br/8030830142710133; Silva, Francine Damian da; 009.510.500-01; http://lattes.cnpq.br/9838212017844050; Silva, Tonny José Araújo da; 781.203.064-49; http://lattes.cnpq.br/0651075688988405The competition between cultures of agricultural interest and invasive plants is a problem that lasts several years, therefore, the industries of agricultural pesticides are the most benefit from this gap in agriculture. But the effects of these pesticides are not yet fully known. Based on this, the goals of this work are to build and evaluate an unmanned ground vehicle, spraying system with fractioned dose; study of photoelectric optical sensor use HC-SR501 PIR, real-time detection of invasive plants in two different surfaces (surface red Latosol, light surface), with five different infestation indices for both; develop a computational program in C language for a lowcost electronics that scan the information captured by the sensor and reverse flow control. Construction and study were conducted at the Federal University of Mato Grosso, câmpus of Rondonópolis, the evaluations were carried out in the experimental area of Agricultural and environmental engineering course, on various conditions (temperature, relative humidity and dust), the split spray system work properly the activity to which it was designed; the VTA proved to be a suitable structure to the study of sensors; the HC-SR501 sensor PIR detected the infrared reflectance of different leaf areas which was submitted, but without reliable results, being the clear surface presented more sense failure.
- ItemDesempenho operacional de uma colhedora de algodão e a variabilidade espacial da qualidade da fibra antes e após a colheita(Universidade Federal de Mato Grosso, 2017-03-10) Crisostomo, William Lima; Mion, Renildo Luiz; 034.525.757-05; http://lattes.cnpq.br/8030830142710133; Mion, Renildo Luiz; 034.525.757-05; http://lattes.cnpq.br/8030830142710133; Viliotti, Carlos Alberto; 081.862.308-07; http://lattes.cnpq.br/1680184849424627; Silva, Francine Damian da; 009.510.500-01; http://lattes.cnpq.br/9838212017844050Cotton is the most important natural source of fiber in the world, with the largest volume of world production, besides being the largest source of raw materials of the textile industry, still provides as the grains by-products that are rich in oils and residues are protein-rich employees mostly in animal feed. Cotton production in Brazilhas expanded in the State of Mato Grosso, where growers have found large tracts of land and favorable conditions for the development of culture, resulting in the rapid growth of the area produced. The State of Mato Grosso is responsible for the whole fibre produced in Brazil 68% of this fibre is produced in Mato Grosso, giving it a leading position worldwide. The characterization of the quality of the fibre produced in commercial plot is important to determine the qualitative variations within a single site enabling the farmer to search for areas that allow the less variability of fiber quality, enabling the adoption of actions that raise the homogeneity of the plot producing higher quality fibersthat offer better remuneration to the producer at the time of sale. The best quality of fiber is set at the moment the ball opens at the end of the cropcycle, the actions taken post harvest should be made properly to prepare these fibers for industrialization, while must preserve the original characteristics of the fiber.While the fiber remains in the field she becomes sensitive to environmental factors that are detrimental to their quality characteristics. To be avoided these potential damage the harvest should be done in short period of time, making it important to the determination of a suitable machines depending on the amount of area to be harvested, in typical conditions of cultivation in Mato Grosso, obtained 60% collection efficiency and operational efficiency of approximately 67.2%. After harvesting andprocessing, spatial variability of fiber quality is completely mischaracterized, mostly by homogenization arising out of the operation mode of the harvester and the waythe processing occurs. When the equipment used in processing are appropriately regulated cannot detect significant changes of qualitative characteristics of the fibers.
- ItemIndicadores de qualidade do solo e sua relação com a produtividade em sistemas integrados de produção agropecuária em plantio direto(Universidade Federal de Mato Grosso, 2018-07-11) Laroca, Jackeline Vieira dos Santos; Souza, Edicarlos Damacena de; 719.200.561-49; http://lattes.cnpq.br/6843055362772781; Souza, Edicarlos Damacena de; 719.200.561-49; http://lattes.cnpq.br/6843055362772781; Silva, Francine Damian da; 009.510.500-01; http://lattes.cnpq.br/9838212017844050; Cabral, Carlos Eduardo Avelino; 019.717.471-06; http://lattes.cnpq.br/6739111102181898The objective of the work was to evaluate the influence of the consortia with leguminosas in the phase pasture of SIPA-PD in the increment of organic matter, in the activity microbiológica of the soil and productivity of grains and production and quality of the pasture. And to identify the indicators of quality of the soil with influences in the changes of the productivity of the system. The experiment was driven in Itiquira (MT) in a Latossolo Red distrófico, where they were implanted, after crop of the soy, the treatments with grassy Urochloa ruziziensis, U. brizantha to cultivate BRS Paiaguás, Panicum maximum to cultivate BRS Tamani and U. brizantha to cultivate BRS Piatã cultivated unmarried and associated with bean caupi (Vigna unguiculata) to cultivate BRS Tumucumaque and bean guandu (Cajanus cajan) to cultivate BRS Mandarim. The experimental delineamento was of blocks casualizados with three repetitions in outline of subdivided portions where the grassy ones were considered as portions and the subparcelas were represented by the leguminosas. It was verified that the consortia provided increments in the tenors of C and N as well as in their fractions particulate and in the index of handling of carbon. C and N of the microbial biomass were also increased by the adoption of the consortia with leguminosas, and the single cultivations presented high values of basal breathing and metabolic quotient, evidencing stress in the microbiota of the soil. Plant productivity was positively influenced by consortiums with cowpea. Dry matter and crude protein have a positive and significant influence on animal production. And the C of the microbial biomass followed by the N in the organic matter was used in the tests that improved explicitly as the changes in productivity. The Paiaguás and Piatã grasses intercropped with leguminous cowpea beans provide greater increases in attributes related to soil quality, also reflecting the higher yields of the system.
