Title A name given to the resource Effect of gamma radiation of 60Co on sunflower plants (Helianthus annuus L.) (Asteraceae), from irradiated achenes Creator An entity primarily responsible for making the resource Díaz, L.E, García, S.A.L., Morales, R.A, Báez, R.I., Pérez, V.E., Olivar, H.A., Vargas, R.E.J., Hernández, H.P., De la Cruz, T.E., García, A.J.M., Loeza, C.J.M. Description An account of the resource In order to know the effect of 60Co gamma irradiation, in the sunflower crop, were irradiated achenesin the Transelektro LGI-01 in the Instituto Nacional de Investigaciones Nucleares. The data wasevaluated under a completely randomized design, where the treatments were 0, 100, 200, 300, 400,500, 600, 700, 800 and 900 Gy and four repetitions (10x4) = 40 experimental units. The responsevariables were: plant height, root length and volume, dry biomass. The results indicated thatgermination and sprouting decreased as the radiation increased, adjusting these to a quadratic model.Plant height, length, root volume and dry biomass decreased at high doses. From this investigation itwas concluded, that doses of 100 and 200 Gy, have a stimulating effect on plant height and root length,being an important agent, to induce genetic variability in sunflower.

Title A name given to the resource AS “AGRURAS"” DA GESTÃO DA PROPRIEDADE RURAL PELA AGRICULTURA FAMILIAR" Creator An entity primarily responsible for making the resource Cidonea Machado Deponti Description An account of the resource RESUMO: O presente artigo é resultado do projeto “Desenvolvimento Rural e Tecnologias de Informação e de Comunicação (TICs)” que visa analisar as possibilidades de introdução de TICs para a agricultura familiar no Vale do Caí, com a experiência de um piloto em Montenegro, município polo desta região, visando o desenvolvimento rural e regional. O artigo foca-se nas atividades de extensão que apresentam como objetivo principal a capacitação das famílias de agricultores familiares em TICs, a partir de diálogos, de discussões, de negociação e da construção conjunta do conhecimento. Para tanto, foram realizadas oficinas de integração com os agricultores versando sobre a utilização das principais TICs e foram construídas de forma coletiva (equipe e agricultores participantes do projeto)planilhas eletrônicas para a gestão da propriedade rural. Além disso, ocorre o monitoramento in loco para acompanhamento e para auxílio ao processo de registro das informações visando construir uma metodologia coletiva com os agricultores, de forma que possam tornar-se autônomos nos processos gerenciais. Concluiu-se que há um gap entre o uso e a apropriação das TICs, ou seja, os agricultores participantes do projeto têm acesso ao computador, à internet, ao celular e ao notebook, no entanto, ao que se refere ao registro das informações e ao controle das despesas e das receitas, não há costume nem compreensão da efetiva necessidade e da utilidade das anotações para embasar a tomada de decisão.

Title A name given to the resource Tratamento de dejetos suínos com biorreator UASB Creator An entity primarily responsible for making the resource Pablo Costa da Silva, Atanásio Alves do Amaral Description An account of the resource Esse trabalho tem por objetivo analisar a importância do biodigestor UASB no tratamento de dejetos suínos. A suinocultura possui papel importante quanto ao desenvolvimento econômico do Brasil. No entanto, o aumento de produção vem causando problemas ambientais graves, por conta do grande volume de resíduos sólidos gerados pela atividade. O desenvolvimento de métodos de tratamento de dejetos que agreguem valor à produção e respeitem as leis ambientais é um dos grandes desafios do setor. A biodigestão anaeróbia é um dos métodos mais eficazes para o tratamento de dejetos de suinoculturas. Este método de digestão, denominado UASB, tem como característica principal a produção de biogás e de biofertilizante, produto rico em nutrientes, e livre de patógenos. O método oferece vantagens como a promoção do bem estar animal, o aumento da fertilidade do solo, a diminuição da poluição e da emissão de gases geradores do efeito estufa e a melhoria da qualidade de vida, nos centros produtores de suínos, além de minimizar problemas relacionados ao déficit de energia elétrica. Portanto, a utilização de biodigestores UASB para o tratamento de dejetos de suínos é uma opção interessante, que deve ser avaliada com seriedade.

Title A name given to the resource Estimation of structural attributes of walnut trees based on terrestrial laser scanning Creator An entity primarily responsible for making the resource J. Estornell, A. Velázquez-Martí, A. Fernández-Sarría, I. López-Cortés, J. Martí-Gavilá, D. Salazar Description An account of the resource Juglans regia L. (walnut) is a tree of significant economic importance, usually cultivated for its seed used in the food market, and for its wood used in the furniture industry. The aim of this work was to develop regression models to predict crown parameters for walnut trees using a terrestrial laser scanner. A set of 30 trees was selected and the total height, crown height and crown diameter were measured in the field. The trees were also measured by a laser scanner and algorithms were applied to compute the crown volume, crown diameter, total and crown height. Linear regression models were calculated to estimate walnut tree parameters from TLS data. Good results were obtained with values of R2 between 0.90 and 0.98. In addition, to analyze whether coarser point cloud densities might affect the results, the point clouds for all trees were subsampled using different point densities: points every 0.005 m, 0.01 m, 0.05 m, 0.1 m, 0.25 m, 0.5 m, 1 m, and 2 m. New regression models were calculated to estimate field parameters. For total height and crown volume good estimations were obtained from TLS parameters derived for all subsampled point cloud (0.005 m – 2 m).

O objetivo do trabalho foi avaliar o crescimento inicial de mudas de Acnistus arborescens em um gradiente de luz. O experimento foi conduzido no Núcleo de Ensino e Pesquisa em Agricultura Urbana, da Universidade Federal do Ceará. Para obtenção das mudas foi realizado a semeadura em bandejas e 30 dias depois as plântulas foram repicadas para sacos de polietileno de 12x25 cm contendo solo e húmus. Os tratamentos foram constituídos de quatro níveis de sombreamento: sol pleno (0% de sombreamento), 50, 70 e 90% de sombreamento, e cinco períodos de avaliação (30, 51, 72, 93 e 114 dias após a repicagem) combinados num arranjo de parcelas subdivididas no delineamento em blocos ao caso com quatro repetições (5 plantas/repetição/período). As variáveis analisadas foram altura, diâmetro, comprimento da raiz, peso da matéria seca das folhas, caule e raiz, área foliar e relação raiz/ parte aérea. A maior altura e produção de biomassa foi observado nas plantas que estavam em ambiente sombreado. Os resultados obtidos mostraram que Acnistus arborescens apresenta um melhor desenvolvimento inicial em ambiente sombreado, e que embora a espécie seja descrita como heliófita, a condição de sol pleno estudada afetou negativamente o desempenho desta espécie.

Nesta perspectiva, nosso estudo se dirigiu à discussão sobre o funcionamento dos conselhos municipais de alimentação escolar (CAE) de Americana, Cosmópolis e Piracicaba. Trata-se de uma análise sobre as compras de produtos da agricultura familiar, interrogando em que medida o Programa Nacional de Alimentação Escolar é considerado como um meio para promover o desenvolvimento local com ênfase no fortalecimento dos agricultores familiares. O conceito de referencial de circuitos curtos de proximidade, vinculado à sustentabilidade agroalimentar, foi considerado em nossa análise. Foram entrevistados, em 2015 e 2016, atores chave do programa nos municípios escolhidos. Nossa pesquisa permitiu constatar que todas as prefeituras estudadas realizam compras de produtos da agricultura familiar. Porém, o fomento ao desenvolvimento local está longe de alcançar o que é recomendado nos documentos do PNAE.  Para atingir o mínimo de 30% dos recursos do Fundo Nacional de Desenvolvimento da Educação (FNDE) transferidos para os municípios para a aquisição de gêneros alimentícios advindos da agricultura familiar, as prefeituras consideradas recorrem frequentemente a organizações distantes de agricultores familiares.

Title A name given to the resource Sistema de Visión Artificial para el Análisis de Imágenes de Cultivo basado en Texturas Orientadas Creator An entity primarily responsible for making the resource Juan Francisco Sotomayor, Alejandro Paúl Gómez, Andrés Fernando Cela Description An account of the resource Dentro del área de la Agricultura de Precisión al obtener la mayor cantidad de información sobre los campos de cultivo se puede optimizar los procesos de siembra, control de malas hierbas y cosecha. Obtener imágenes con cámaras sobre vehículos aéreos no tripulados está siendo actualmente una solución viable para esta tarea, por lo que el procesamiento y análisis de las imágenes aéreas brindaría mayor información al navegar sobre un cultivo. El presente trabajo muestra el desarrollo de un sistema de visión para detectar la dirección de las líneas de cultivos de trigo de imágenes aéreas basándose en el análisis de texturas orientadas; tres estrategias son propuestas para afrontar las diferentes situaciones de las imágenes de cultivo: poca capa vegetal, rodales de mala hierba, variabilidad de la iluminación, escalado de la imagen, entre otras. Las pruebas han sido realizadas con un repositorio de imágenes propio, logrando resultados muy satisfactorios que indican una respuesta en tiempo real, manteniendo un alto nivel de eficiencia en la detección de la dirección de las líneas de cultivo.   Abstract: In the area of Precision Agriculture to get most information about the farmlands is possible to optimize the processes of: planting, weed control and harvesting. Obtaining images with cameras on unmanned aerial vehicles is currently an able solution for this task. The processing and analysis of aerial images would provide more information when we browse on a crop. This paper shows the development of a vision system to detect the direction of the lines of wheat crops using aerial images based on texture analysis oriented, three strategies are proposed to tackle different situations in crop images: little topsoil, weed zones, variability of the illumination, image scaling. The tests were conducted with an own repository of images with highly satisfactory results. Also, the results indicate a response in real time, while the detection of the crop rows direction is keep at high level of efficiency.

Title A name given to the resource Uso de bioestimulantes no crescimento de plantas de soja Creator An entity primarily responsible for making the resource Valdere Martins dos Santos, Dione Pereira Cardoso, Daniele de Cássia Vieira de Sousa, Aurélio Vaz de Melo, André Henrique Gonçalves, Átila Reis Silva Description An account of the resource Na agricultura atual, o uso de produtos bioestimulantes, tornou-se uma opção viável e econômica, para a obtenção de altos rendimentos e melhorias na qualidade do produto. Embora, poucos estudos tenham abordado, o efeito dos bioestimulantes sobre os aspectos biométricos. Portanto, objetivou-se avaliar o uso de bioestimulantes, isolados e combinados, no desempenho agronômico de plantas de Glycine max (L.). O experimento foi conduzido em casa de vegetação na Universidade Federal do Tocantins, Gurupi-TO. Os tratamentos foram constituídos por três bioestimulantes (BU-RG, BU-EC e BU-VG) utilizados em aplicações de três maneiras (via semente, via foliar e combinados). O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições. Foram avaliadas as seguintes características; altura das plântulas, diâmetro do caule, massa seca de folhas, massa seca de caule, massa seca de raízes e volume do sistema radicular. O bioestimulante BU-EC aplicado via semente apresentou a maior taxa de crescimento em altura de plântulas. A combinação dos bioestimulantes BU-RG via semente + BU-VG via foliar, promoveu a maior taxa de acúmulo de massa seca da folha.
