Description
An account of the resource
El objetivo del presente trabajo fue realizar una revisión acerca de las mezclas de materiales orgánicos e inorgánicos utilizados en la elaboración de un nuevo material, el tamaño de partícula, la proporción y su respuesta en planta. En México, los desechos agropecuarios son considerados un reservorio de contaminantes; sin embargo, desde otra perspectiva, representan una industria con mucho potencial. Los nutrientes ingeridos por los animales representan nutrimentos disponibles para las plantas cuando son reciclados adecuadamente. Una de las opciones que minimiza el riesgo de contaminación y mejora su calidad, es la elaboración de compostaje y vermicompost. Ambos procesos constituyen una alternativa para la producción orgánica. Un material por si solo no cumple con las condiciones óptimas. La reducción del volumen de un material orgánico aumenta la compactación y la compresión de las raíces, afectando la eficiencia de riego y la fertilización, por lo que es necesario hacer mezclas con materiales inorgánicos, lo cual se aprovecha en la elaboración de un nuevo material para obtener mejores condiciones de crecimiento para la planta.

Description
An account of the resource
Com a expansão do comércio de cultivares híbridas, várias comunidades rurais têm abandonado suas sementes tradicionais, tornando o camponês mais dependente de multinacionais do setor de sementes. Porém, as sementes locais têm sua importância, seja do ponto de vista genético, ambiental, social e até mesmo econômico, e com base nisso, foi instalado um ensaio com cinco variedades crioulas e uma cultivar comercial de milho visando avaliar características de crescimento e produção, em sistema orgânico de produção na região semiárida do estado do Rio Grande do Norte. O ensaio foi conduzido na Horta Experimental do Instituto Federal do Rio Grande do Norte - Campus Ipanguaçu, com delineamento experimental em blocos ao acaso com três repetições e seis tratamentos. As variedades crioulas apresentaram o mesmo desempenho de crescimento e de produção observado na cultivar híbrida, com exceção para a característica massa de 100 grãos, em que a cultivar híbrida tendeu a apresentar os menores valores.

Description
An account of the resource
A técnica de solarização e da cobertura vegetal são estratégias de manejo de plantas daninhas importantes para reduzir a mão-de-obra e outras limitações impostas pelo controle mecânico, porém a eficiência e resposta na composição florística desses métodos varia conforme manejo realizado na agricultura familiar. Dessa forma, o objetivo desse trabalho é avaliar o efeito supressivo da solarização e cobertura com capim-elefante (Pennisetum purpureum Schum.) sobre a emergência de plantas daninhas, bem como identificar e quantificar as espécies daninhas presentes através do levantamento fitossociológico. O experimento foi conduzido a campo no ano agrícola 2017/2018, utilizando delineamento experimental em blocos casualizados e quatro repetições. Os tratamentos foram dispostos em esquema fatorial, onde o fator A compara a solarização (presença e ausência); e o fator B a cobertura com capim-elefante (sem e com). Realizou-se o levantamento fitossociológico e avaliação da massa seca da parte aérea das plantas daninhas em resposta aos tratamentos. A adição do capim-elefante na superfície do solo atua como supressor da diversidade de plantas daninhas, como Ageratum conyzoides, Urochloa plantaginea, Galinsoga parviflora, Polygonum persicaria, Spermacoce latifolia, Sida sp. e Stachys arvensis. Enquanto que a solarização, aumenta o valor de importância do Cyperus sp. nas parcelas sem a utilização da cobertura vegetal. Ainda, a solarização realizada por 20 dias não foi eficiente para o controle das plantas daninhas.

Se cuantificó para la cuenca del lago de Chapala, porción Michoacán, México, la pérdida de suelo por erosión hídrica, utilizando como método de medición las parcelas de escurrimiento. Un total de 18 de ellas se instalaron por los principales usos de suelo presentes en la región: pastizal, agricultura de riego y de temporal, bosque de encino y matorral subtropical. Se realizó un muestreo mensual durante el periodo de lluvias que abarcó los meses de agostooctubre de 2012. La mayor pérdida de suelo se presentó donde se desarrolla la agricultura de temporal con 630.7 kg ha-1, seguido de los pastizales con 87.9 kg ha-1 y en menor cantidad el bosque de encino con 3.9 kg ha-1. Considerando todos los usos de suelo, en total la pérdida de suelo en la zona de estudio fue de 6 593 t ha-1 año-1, siendo mayor en las áreas de cultivo de temporal con 4 019 t ha-1 año-1. La materia orgánica fue uno de los componentes del suelo que más se perdieron durante el proceso de erosión hídrica, obteniendo valores de 24.5 y 5.1 kg ha-1 para cultivos de temporal y pastizales, respectivamente. Los macronutrientes medidos en el sedimento igualmente presentaron una correlación con el factor anterior; los máximos valores para N, P y K se registraron en la agricultura de riego con 0.9, 0.1 y 2.1 kg ha-1, respectivamente.

O objetivo do trabalho foi avaliar o estabelecimento populacional das comunidades das plantas daninhas, durante seis anos agrícolas consecutivos de milho cultivado no sistema plantio direto orgânico e tradicional, intermediado por um sistema de plantio convencional. Os experimentos foram conduzidos nos anos agrícolas 2003/04 até 2008/09. O delineamento experimental adotado foi o de blocos casualizados com quatro repetições. Os tratamentos avaliados foram: SDT1 (semeadura direta sem adubação e com aplicação de herbicidas no manejo das plantas daninhas); SDT2 (semeadura direta com adubação mineral na dose de 300 kg ha-1 do formulado 8-28-16 + 100 kg ha-1 de nitrogênio em cobertura, e com aplicação de herbicidas); SDT3 (semeadura direta, adubação com composto orgânico, na dose de 40 m³ ha-1, e com aplicação de herbicidas); e SDO (semeadura direta utilizando composto orgânico, na dose de 40 m³ ha-1, e roçada no manejo das plantas daninhas). Concluiu-se que a dinâmica populacional de plantas daninhas na cultura do milho foi influenciada pelo manejo do solo (aração e gradagem) e que o tipo de adubação não proporcionou alteração na dinâmica populacional.The aim of this work was to evaluate the weed establishing (and unwanted plant) populations during six consecutive agricultural years for maize crops. The systems studied were till, both organic and traditional, intermediated by a traditional plantation system. The experiments were carry out in the agricultural years 2003/04 until 2008/09, in the experimental area in southeast of the Minas Gerais State), which is owned by the Federal University of Viçosa. The treatments were SDT1 (till without fertilizer and herbicide application ); SDT2 (till with mineral fertilizer (300 kg ha-1 with of 8-28-16 (N-P-K) plus 100 kg ha-1 of nitrogen for side fertilization, and the herbicide application): SDT3 (till with fertilizer with organic compost in a dose of 40 m³ ha-1 and herbicide application ); SDO (organic till with organic compost in a dose of 40 m³ ha-1, and mowing). We can conclude that the herbicide application or the clearing of the ground stimulated a greater alteration in the establishing of weed (unwanted plant) communities than the type of fertilizer used.

Agronomic parameters were assessed in broccoli ( Brassica oleraceae L. var. italica), cv. Legacy, in different cultivation systems: Natural 1 [incorporation of elephant grass Pennisetum purpureum Schumacher cv. “Napier” (50 ton/ha), Bokashi compost (1,5 ton/ ha) and EM-4 spraying (20 l/ha)]; Natural 2 [Bokashi compost (1,5 ton/ ha) and EM-4 spraying (20 l/ha)]; Conventional (NPK in the planting + bórax + dressing N)]; Organic [organic compost (1 kg/plant)]. Plants high were assessed 30, 45 and 60 days after planting; cycle; fresh weight; shelf life and dried weight were also evaluated. Fresh weight of leaves and stems in conventional was higher then in organic treatment. Inflorescence fresh weight, leaves and stems dried weight and shelf life were similar among treatments. The inflorescence fresh and dried weight from conventional were higher than those from Organic and Natural 1. Cycle found in Natural 1 was longer than the other treatments.Parâmetros agronômicos foram avaliados em couve-brócolos ( Brassica oleraceae L . var. italica), cv. Legacy, em quatro sistemas de cultivo: Natural 1 [incorporação de capim elefante Pennisetum purpureum Schumacher cv. “Napier” (50 ton/ha), composto Bokashi (1,5 ton/ ha) e pulverização de EM-4 (20 l/ha)]; Natural 2 [incorporação de composto Bokashi (1,5 ton/ ha) e pulverização de EM-4 (20 l/ha)]; Convencional [NPK no plantio + bórax + N em cobertura]; Orgânico [aplicação de composto (1 kg/planta)]. Avaliou-se a altura das plantas aos 30, 45 e 60 dias após o transplantio; duração do ciclo, peso fresco, período de conservação pós-colheita e peso seco. O peso fresco da parte vegetativa obtido no sistema convencional foi superior ao sistema orgânico. O peso fresco e seco da inflorescência obtido no sistema convencional, foi superior àquele obtido nos sistemas Orgânico e Natural 1. O ciclo no sistema Natural 1 foi mais longo do que nos outros tratamentos.

Description
An account of the resource
Chusquea quila or “quila”, is one of the most abundant lesser-known species from Chile, and for many years it has created problems for farmers in the southern part of this country. In this study, it was examined as a promising resource for high-tech materials. The chemical and physical properties were determined by ASTM standards. The extractives, ash content, lignin, and alpha-cellulose were 4.55%, 2.17%, 13.78%, and 54.65%, respectively. The higher heating value and basic density obtained were 5,106 kcal/kg and 290 kg/m3, respectively. The moisture content was studied during four seasons and found to be the highest in winter (73%). Regarding the nanomechanical profiles, hardness varied from 0.16 GPa in the cortex to 0.21 GPa in the nodule. The average elastic modulus in the nodule and internode was 12.5 GPa, while in the cortex it was 7.45 GPa. Considering the high cellulose content and structural features of the lignocellulosic matrix, it could be possible to extract cellulose fibers for commercial use and crude lignin for testing new applications. Thus, the entire quila structure is a potential biomass resource.

Description
An account of the resource
El maíz es el segundo cereal de mayor producción en Colombia con un 21,9 % de la superficie total. La plaga Spodoptera frugiperda ataca la planta desde las primeras semanas de crecimiento, devorando sus hojas, tallo y granos; disminuyendo el rendimiento de los cultivos. Esta plaga se controla con el uso indiscriminado de plaguicidas sintéticos como: carbofurano, clorpirifos y atrazina. En esta investigación, los extractos de Azadirachta indica, Piper nigrum, Petiveria alliacea y sus mezclas; y los extractos de Nicotiana tabacum, Lippia alba, Allium sativum y sus mezclas se aplicaron como bioplaguicidas en plantas de maíz amarillo tradicional. Después de la tercera semana de crecimiento, los tratamientos se aplicaron dos veces al día cada tres días durante siete semanas. Las variables estudiadas fueron número de larvas muertas, altura de las plantas y daño en hojas y tallos. Las plantas tratadas crecieron dos veces más y su grado de afectación, según la escala de Mihm, fue menor que las plantas del grupo testigo. Los porcentajes de eficacia de las seis especies vegetales y sus mezclas fueron representativos (>80 %), de acuerdo con Henderson y Tilton, demostrando que estos extractos vegetales son una alternativa viable para el control de S. frugiperda.

Description
An account of the resource
Durante tres años se condujo un experimento en áreas del Instituto de Investigaciones de Viandas Tropicales (INIVIT) de Camagüey, empleando diferentes abonos organo-mineral, con el objetivo de conocer su influencia en el rendimiento del maíz (Zea maiz, L), sobre un suelo Pardo Sialítico Mullido Carbonatado de pH ligeramente ácido, bajo contenido de P2O5 y medio de K2O y materia orgánica. Para las mezclas organo-mineral se emplearon como abonos orgánicos el estiércol vacuno y la cachaza y como fertilizantes minerales, el superfosfato triple y el cloruro de potasio. El organo-mineral se aplicó en el momento de la siembra a una dosis de 745 kg ha1 de acuerdo a cada tratamiento, los que fueron replicados 4 veces en un diseño de bloques al azar. Se midió el rendimiento y sus componentes y se tomaron muestras de suelo para conocer la variación de sus propiedades. Los datos fueron evaluados por un análisis de varianza de clasificación doble y se aplicó la prueba de rango múltiple de Duncan para un nivel de significación del 5 %. Los resultados muestran que el empleo de los abonos organo-minerales favorece el rendimiento, reducen los fertilizantes químicos a emplear y mejoran las propiedades del suelo.

Description
An account of the resource
O objetivo deste trabalho foi analisar os alimentos disponíveis para consumo, sua origem e a situação de (in)segurança alimentar e nutricional de famílias da Zona da Mata de Minas Gerais. O estudo foi realizado com 10 famílias, totalizando 40 pessoas, das quais foram avaliados o peso e a estatura. Para investigação da disponibilidade de alimentos foi utilizado questionário contendo lista de procedência e quantidade mensal destes nos últimos 30 dias. Os resultados indicaram 62,5% de indivíduos eutróficos, 30% com excesso de peso e 7,5% com baixo peso, sendo a maioria dos casos de inadequação em mulheres. A média da disponibilidade calórica supre 156,5% da necessidade calórica das famílias, classificando todas em segurança. Das calorias disponíveis, 40,5% provinham da produção para o autoconsumo e a participação dos macronutrientes indicou carboidratos 50,6%, proteínas 11,5% e lipídeos 37,8%. Apesar da classificação de segurança, o excesso de calorias disponíveis é preocupante, pois a totalidade da sua ingestão pode agravar o quadro atual de 30% da população com excesso de peso e a qualidade dos alimentos disponíveis não apresentou a adequação esperada, tornando essas famílias mais propícias a apresentarem insegurança alimentar. É importante incentivar a produção para autoconsumo, pois esta pode contribuir para o alcance da segurança alimentar e nutricional das famílias.
