Cabbage is a vegetable of European origin cultivated in all regions of Brazil during the periods of the year. It is an herbaceous plant with an exotic flavor and a great alternative for use in the kitchen. It has a short cycle and a high production capacity, which indicates the need to adopt adequate management measures to guarantee the expected productivity. Among the management practices, correct fertilization is essential for the supply of essential nutrients and, currently, numerous biofertilizers products are marketed. Therefore, the aim of this work was to determine the effect of different doses of a commercial biofertilizer for cabbage seedling production. The experiment was conducted and conducted in an IFMG greenhouse - Campus Bambuí Olericulture Sector, in a completely randomized design with seven treatments and four replicas. The treatments consisted of different doses of bio-fertilizer applied to cabbage seeds (control - without biofertilizer; 1 ml /L-1; 1.5 1 ml /L-1, 2 1 ml / L-1, 2.5 1 ml / L-1, 3 1 ml /L-1 and 3, 5 1mL / L-1). Cabbage seeds of the Mammouth Red Rock cultivar were used, sown in pellets of 128 cells with commercial substrate. The following characteristics were evaluated: seedling height, number of leaves, stem diameter, green weight of the shoot, green weight of the root, length of the root, dry weight of the shoot and dry weight of the root. The data obtained were subjected to analysis of variance and regression using the statistical program SISVAR 5.0 (FERREIRA, 2011). The analyzes revealed significant differences between the different dosages for all the characteristics evaluated. For the green weight characteristic of the aerial part the best dosage was 3 ml / L and for the other characteristics the dosage of 3.5 ml / L was the one that promoted the best performance. cabbage seedlings production.

Lettuce is one of the main leafy vegetables worldwide known and of great importance in the population's diet. Irrigations for lettuce crop should be performed frequently throughout its development cycle due to its requirement in water. With the advancement of technology and the need for information to be optimized for agricultural processes, the use of remote monitoring is becoming increasingly used in precision agriculture. Thus, the present work aimed to evaluate the productivity of lettuce crop, grown in open environment, using an unmanned aerial vehicle (UAV) to detect water requirement and irrigation intervals through the spectral response of the crop. The experiment was carried out in the Olericulture sector of the Federal Institute of Minas Gerais - IFMG Câmpus Bambuí, using the Solaris lettuce cultivar at 30 cm x 30 cm spacing. The experimental design was randomized blocks with 4 replications and 5 treatments, totaling 20 experimental units. The treatments were characterized by irrigation intervals, T1: Daily Irrigation (Witness); T2: <80% Water Sufficiency Index (ISA); T3: <70% ISA; T4: <60% ISA; T5: <50% ISA. The following variables were evaluated: head diameter, shoot fresh mass, leaf numbers, shoot dry matter, shoot height, chlorophyll content and yield. Variable data were subjected to analysis of variance with the F test and regression analysis at a significance level of 5% probability. All the analyzed variables were influenced by the irrigation intervals adopted in this work determined by the proposed Water Sufficiency Index, being the best treatment the daily irrigation with a fixed 5mm blade for lettuce crop. The use of unmanned aerial vehicle with coupled camera that captures in the visible region was not efficient for the management of irrigation for lettuce crop from plant reflectance.
Componente arbóreo em sistemas de integração lavoura pecuária floresta: revisão bibliográfica.
Oliveira, Thaynara Lopes De; Botrel, Maria Carolina Gaspar; Arnésio, Arnon Henrique Campos
The integrated crop-livestock-forest system (ICLF) has been a socially and economically viable alternative, as it adopts management systems that promote improvements in soil quality, increase in carbon stocks, recovery of degraded agricultural areas, based on synergism of the components of the productive system. Therefore, this work had as main objective to perform a bibliographic survey about the ICLF system, emphasizing the arboreal component. The methodology adopted is based on a bibliographic review using papers from SciELO, CAPES Periodical, Digital Library of Theses and Dissertations (BDTD), and Google Scholar databases. The behavior of tree species within ICLF systems was considered from the information of the last 10 years. The tree components studied in the present work were the forest species Eucalyptus spp. (eucalyptus), Pinus elliottii (pine), Khaya spp. (African mahogany), Toona ciliata (Australian cedar), Tectona grandis (teak), Acacia mangium (acacia), and Hevea brasiliensis (rubber tree), which play an important role within the integration systems about proper soil management, in addition to its economic role due to the various uses of wood.
Produção de mudas de café arábica com substrato contendo esterco de curral coletado em diferentes épocas.
Lara, Matheus Arcanjo; Dias, Fábio Pereira
The production of quality seedlings is a determining factor in the success of the coffee plantation. The standard substrate used for seedlings produced in polyethylene bags has tanned and sieved barnyard manure in its composition, which is largely responsible for the nutritional supply, especially nitrogen, in addition to adding physical and biological benefits to the substrate. However, the ideal time for seedling production is preceded by the rainy season, causing difficulty in collecting manure with the desired characteristics in large volumes, having as a possible solution the early collection of manure in previous years, followed by its storage. In this sense, the present work aimed to evaluate the influence of the use of barnyard manure stored in previous years on the quality of coffee seedlings. To this end, an experiment was carried out at Fazenda João Arcanjo, in the municipality of Candeias-MG, in which a randomized block design was adopted consisting of four treatments, with manure collected in the year 2019, 2020 and 2021 collected in the region of Bambuí. -MG, in addition to a plot collected in 2021 in the region of Candeias-MG, with five replications, totaling twenty experimental plots, consisting of 24 plants per plot. The data of the variables evaluated were submitted to analysis of variance (ANOVA) using the F test at a 5% probability level and the means were compared using the Scott-Knott test. A significant difference was observed for all variables evaluated as a function of manure storage time, with a decrease in seedling quality as a function of the increase in manure storage time.

Este estudo, desenvolvido no âmbito do Mestrado em Educação Profissional e Tecnológica (ProfEPT), investigou as funções da biblioteca na Educação Profissional e Tecnológica (EPT). Objetivou-se analisar suas contribuições e possibilidades de atuação, com ênfase no papel social da biblioteca como espaço de convivência e ambiente de expressão, visando à formação omnilateral das comunidades interna e externa. A pesquisa caracteriza-se como qualitativa, de caráter exploratório e orientação analítico-descritiva, e adota a abordagem da pesquisa-ação (Tripp, 2005). Os procedimentos metodológicos incluíram análise documental, entrevistas semiestruturadas com a representante da Seção de Extensão da Diretoria de Extensão, Cultura e Esporte do campus Bambuí, e a realização de um Círculo de Cultura com estudantes do campus, método proposto por Paulo Freire. Para a análise das contribuições, utilizou-se o método denominado Análise de Conteúdo de Bardin (1977). Os resultados indicam que a biblioteca não atinge plenamente seu potencial social. No entanto, observou-se a possibilidade de integrar as funções tradicionais e sociais, com a tecnologia como aliada da educação, por meio de um conhecimento sistematizado das comunidades atendidas e da participação ativa dessas nas práticas biblioteconômicas. Este estudo culminou na criação do Produto Educacional “Biblioteque-se: Caminhos de Convivência, Memória e Pertencimento para a Biblioteca Comunitária Professora Ebe Alves da Silva” que visa consolidar o papel da biblioteca como espaço de convivência, formação, memória e produção cultural, promovendo o diálogo entre as comunidades interna e externa ao campus.
