Title A name given to the resource Enraizamiento de esquejes de Salicornia bigelovii (Torr.) por quitosano como un bioproducto de origen marino Creator An entity primarily responsible for making the resource Betzabe Ebenhezer López-Corona, Iram Mondaca-Fernández, Pablo Gortáres-Moroyoqui, María Mercedes Meza-Montenegro, José de Jesús Balderas-Cortés, Cristina Ruiz-Alvarado, Edgar Omar Rueda-Puente Description An account of the resource El aprovechamiento de halófitas como Salicornia bigelovii representa una alternativa con potencial económico para la agricultura del desierto y zonas costeras. No obstante, el éxito en el establecimiento de parcelas comerciales se ha visto limitado por los bajos porcentajes de germinación de la especie. La propagación por esquejes representa una opción viable y rápida a esta problemática. La formación de raíces funcionales es fundamental en la propagación por esquejes y se ha logrado mediante la aplicación de productos químicos reguladores de crecimiento. La aplicación de quitosano en algunos cultivos ha mostrado ser una alternativa en el proceso de germinación y mejores rendimientos de cosecha; sin embargo, con relación a la halófita S. bigelovii, son nulos los estudios sobre el efecto del quitosano. El objetivo de la presente investigación fue evaluar el efecto del quitosano de origen marino y el ácido indol butírico como agentes promotores de raíces en esquejes de Salicornia bigelovii. Se aplicaron las concentraciones (individual y en conjunto) de quitosano al 100 y 50% y ácido indol butírico a razón de 0.937 y 1.25 g kg-1. Se utilizó un diseño completamente al azar con nueve tratamientos con cinco repeticiones, evaluándose 225 unidades experimentales. Como variables respuesta se midieron: longitud radicular, peso fresco y peso seco total de la raíz, número y longitud de nuevos brotes. Los resultados indican que el tratamiento más eficiente fue 100% de quitosano + 0.937 g kg-1 de ácido indol butírico, el cual promovió la producción de brotes fotosintéticos hasta en un 800%. Estos resultados demuestran que es factible lograr la propagación de Salicornia mediante esquejes utilizando quitosano de origen marino como promotor de crecimiento.

Title A name given to the resource Contraste entre duas metodologias de determinação do potencial agrícola das terras nas vilas rurais no município de Rio Negro, Estado do Paraná = Contrasts between two methodologies used to determine the agricultural potential of land in rural villages located in Rio Negro, Paraná State, Brazil Creator An entity primarily responsible for making the resource Gilmar Pinto da Costa, Jorge Luiz Moretti de Souza, Márcia Regina Gomes de Jesus Description An account of the resource O presente trabalho teve como objetivo identificar e contrastar o potencial agrícola das terras em duas vilas rurais situadas no município de Rio Negro, Estado do Paraná, utilizando duas metodologias consagradas na literatura, denominadas Sistema deCapacidade de Uso (SCU) e Aptidão Agrícola (SAA). As vilas rurais foram escolhidas, por se encontrarem na mesma região e possuírem características distintas quanto às condições de solo e relevo. O contraste entre as metodologias fundamentou-se nos fatores limitantesdas terras e nas dificuldades e peculiaridades apresentadas no assentamento de famílias rurais em pequenas áreas. As análises e os resultados evidenciaram que: (a) o SAA mostrouse mais apropriado do que o SCU para determinar o potencial agrícola das terras nas duasvilas rurais analisadas; (b) tanto o SAA como o SCU indicam que as terras das duas vilas não apresentam potencial agrícola para serem utilizadas com cultivos anuais; (c) o SCU mostrou-se mais restritivo na determinação do potencial agrícola das terras.The objective of this work was to analyze the agricultural potential of land in two rural villages, located in Rio Negro, Paraná State, Brazil, using two methodologies denominated Land Use Capability (SCU) and Land Agricultural Aptitude (SAA). The rural villages were chosen for their distinct characteristics of soil and slope conditions. Thecontrast between the methodologies was based on the land limiting factors as well as on the social factors involved in the family settlement in small farms. The results showed that: (a) the SAA was more appropriate than SCU for determining the agricultural potential of the lands; (b) the SAA and SCU indicate that the lands of the two villages do not feature the agricultural potential for annual cultivations; (c) the SCU was more restrictive on the agricultural potential of the land than the SAA.

Title A name given to the resource Intoxicados e silenciados: contra o que se luta? Creator An entity primarily responsible for making the resource Larissa Carvalho de OLIVEIRA Description An account of the resource This paper deals with the spraying of pesticides through agricultural aircraft on the rural School São José do Pontal, located in the settlement Pontal do Buriti, Rio Verde-GO. It occurred on the morning of a Friday, at the beginning of month of May 2013. This severe situation reflects the structure of a hegemonic and suicidal model of agricultural production, that is prevalent in the region and is imposed on the countryside. Moreover, there is real death of voices who dare fighting against it and seek for appropriate health treatment for the affected people. They are voices of members of the settlement community, which has no space in the media and, therefore, needs to be mediated by legislators or by the Ministério Público. The media is silent as to the accountability of those who gave cause to the aerial spraying of pesticides that poisoned people and contaminated the school and community environment of the settlement. It merely reported that there were arrests and releases, on bail. However, the timid and insufficient discussion on the problems brought by agribusiness started with some representatives of the people. Thus, this study aims to identify what was reported in the media about the case, establish a mnemonic record of attempts to arrange actions to treat health of victims, between 3 May 2013 and 29 October same year, and to begin reflecting about the fact through bibliographic study.

En los tratamientos con biofertilizante se inoculó la semilla con Glomus intraradices + Azospirillum brasilense; en la fertilización química se aplicó 120N-80P-80K. Se midieron las variables: altura, diámetro del cuello y número de hojas de la planta, número y peso de mazorcas con y sin brácteas, peso de brácteas, longitud y diámetro de la mazorca, número de hileras mazorca-1, peso de grano de 5 mazorcas, longitud, diámetro y peso del olote, rendimientos de grano, de forraje zacateado y de molido seco; para determinar la rentabilidad de los sistemas se calcularon el costo total (CT), ingreso total (IT), ingreso neto (IN) y la ganancia por peso invertido (GPI). El análisis estadístico incluyó análisis de varianza y prueba de comparaciones de medías con el método de Tukey. Se encontró que el híbrido DK357 registró la mayor altura, número de hojas, peso de grano, longitud de mazorca y del olote, rendimiento de grano y forraje tanto zacateado como molido seco. El genotipo P4082W obtuvo el mayor peso de mazorca con y sin brácteas. La fertilización química favoreció el rendimiento de forraje zacateado, y en combinación con la biológica, incrementó el rendimiento de grano. Los híbridos DK357 y P4082W cultivados con fertilización química y biológica resultaron rentables en los sistemas para producción de grano solo, forraje zacateado y grano y forraje seco molido.

Para tanto, foram conduzidos quatro experimentos, nos anos agrícolas de 1999/00 a 2002/03, avaliando os tratamentos: testemunha sem aplicação de N em cobertura; 20 kg ha-1 de N aplicado em cobertura; 40 kg ha-1 de N aplicado em cobertura; 90 kg ha-1 de N aplicado em cobertura; 50 g ha-1 de Rizogram®; 100 g ha-1 de Rizogram®. Verificou-se interação dos tratamentos com os anos avaliados, o que pode ter ocultado o desempenho destes. Além disso, verificou-se que, para a variável “número de grãos por panícula”, a utilização de cianobactérias nas duas dosagens estudadas (50 e 100 g ha-1) produziu resultados semelhantes à adubação nitrogenada (90 kg ha-1), com potencialredução do número porcentual de espiguetas estéreis. Os tratamentos não afetaram o rendimento de grãos do arroz irrigado, devido às variações ambientais dos anos avaliados.A four-year experiment irrigated rice was carried out in order to evaluate the performance of Nostoc sp. and Tolypothrix sp. nitrogen-fixing cyanobacteria strains (Rizogram™), as an alternative to chemical nitrogen fertilization in irrigated rice. The treatments evaluated in the experiments included: control without top dressing Napplication; top dressing application of 20, 40 and 90 kg ha-1; 50 g ha-1 of Rizogram™, and 100 g ha-1 of Rizogram™. It was verified interaction between the years of the study and the treatments, which may have affected the performance of these treatments. Moreover, it was observed that, for the number of grains per panicle, the use of cyanobacteria in two studied rates (50 e 100 g ha-1) produced the same results as the nitrogen fertilization (90 kg ha-1), showing potential reduction of sterile spikelets. However, the treatments did not affected rice grain yield.

Title A name given to the resource DESARROLLO DE UN PENETRÓMETRO INTEGRADO CON TECNOLOGÍA GPS-RTK PARA LA GENERACIÓN DE MAPAS DE RESISTENCIA A LA PENETRACIÓN DEL SUELO Creator An entity primarily responsible for making the resource Santos Gabriel Campos Magaña, Juan Antonio López López, Martín Cadena Zapata, Marco Antonio Reynolds Chávez, Neftali Cuervo Piña, Gabriela Ramírez Fuentes Description An account of the resource La agricultura de precisión requiere información precisa acerca de las propiedades del suelo para optimizar la aplicación de insumos y satisfacer necesidades específicas de los cultivos. En particular, la resistencia a la penetración (RP) que es un factor que mide la compactación del suelo, la cual limita el crecimiento de las raíces y el rendimiento del cultivo, lo cual requiere ubicar y cuantificar el valor de RP. El presente trabajo describe el desarrollo de un penetrómetro integrado con dos sensores (resistencia y profundidad) aplicados junto con tecnología de Posicionamiento Cinemátio en Tiempo Real-Sistema de Posicionamiento Global para Agricultura (RTK-AgGPS) para la generación de mapas de diagnóstico de capas compactadas. El primer sensor fue desarrollado para la medición de la RP utilizando un transductor de anillo simple con capacidad de hasta 9 MPa, con una sensibilidad de 13.5 Nm V-1 y un coeficiente de correlación de 99.6% entre la fuerza aplicada y el voltaje de salida. El segundo sensor, se adecuó para determinar la profundidad de RP con un desplazamiento de trabajo máximo de 0.60 m, con una sensibilidad de 258.5 mm V-1 y un coeficiente de correlación de 100% entre la profundidad de penetración y voltaje de salida. Para la evaluación en campo, se construyó un carro porta-sensores acoplado al enganche del tractor para el accionamiento del actuador hidráulico del penetrómetro. Se realizó un muestreo sistemático de 30 puntos utilizando la tecnología RTK-GPS obteniendo los valores y localización geo referenciada de RP con una precisión de 0.025 m en una profundidad de trabajo hasta de 0.40 m, esto permitió la generación de mapas de diagnóstico de la RP empleando un Sistema de Información Geográfica para tres profundidades diferentes de 0.20, 0.30 y 0.40 m.

O delineamento foi de blocos casualizados, com 4 repetições. Os tratamentos constaram da combinação de doses de bioestimulate, aplicadas via semente (0, 3 e 5 mL kg-1 de sementes) na semeadura e via foliar (0,0; 0,075; 0,150 e 0,225 mL L-1), aos 58 dias após a emergência (DAE). Realizaram-se coletas de plantas aos 73 e 129 DAE.Para algumas das variáveis estudadas, nas doses utilizadas, houve efeito negativo na resposta à aplicação de bioestimulante, para algumas doses testadas. Respostas positivas foram verificadas para massa seca de flores, raízes, razão raiz/parte aérea, número de flores, vagens e grãos e produção por planta. Destacaram-se positivamente os tratamentos: 0,0 mL 0,5 kg-1 (AS) + 0,150 mL L-1 (APF); 3,0 mL 0,5 kg-1 (AS) + 0,0 mL L-1 (APF); 3,0 mL 0,5 kg-1 (AS)+ 0,225 mL L-1 (APF) e 5,0 mL 0,5 kg-1 (AS) + 0,075 mL L-1 (APF).Aiming to verify the effect of the bioestimulant, Stimulate®, applied saw by seed and leaf pulverization, in the culture of the soybean. It behaved an experiment under greenhouse, in vases. Randomized block experimental design was used, with four repetitions. The treatments consisted of the combination of bioestimulant doses: seed application (SA) (0; 3; and 5 mL kg-1 of seeds) in the sowing and leaf spray (LS) (0.0; 0.075; 0.150; and 0.225 mL L- 1), to the 58 days after the emergency (DAE). Collections of plants were accomplished to the 73 and 129 DAE. For some of the studied variables, in the used doses, there was negative effect in the response of the biostimulant application, for some tested doses. Positives responses were verified for flowers and roots dry mass; root/shoot relation; flowers; beans and grains number; and yield for plant. They stood out the treatments: 0,0 mL 0.5 kg-1 (SA) + 0.150 mL L-1 (LS); 3.0 mL 0.5 kg-1 (SA) + 0.0 mL L-1 (LS); 3.0 mL 0.5 kg-1 (SA) + 0.225 mL L-1 (LS); and 5.0 mL 0.5 kg-1 (SA) + 0.075 mL L-1 (LS).

Title A name given to the resource Efecto de medicamentos homeopáticos en plantas de tomate (Solanum lycopersicum L.) Creator An entity primarily responsible for making the resource José Manuel Mazón-Suástegui, Fernando Abasolo-Pacheco, Boris Bonilla-Montalván, Cesar Bermeo-Toledo, Yarelys Ferrer-Sánchez, Andy J. Ramírez-Castillo, Erika Mesa-Zavala, Luis Llerena-Ramos Description An account of the resource El uso de agroquímicos en los cultivos hortícolas generan efectos negativos, por lo que se busca disminuir o eliminar su uso mediante otras técnicas menos toxicas. La homeopatía agrícola representa una alternativa para la agricultura ecológica, incidiendo de manera positiva en el desarrollo de los cultivos. Se evaluó el efecto de cuatro medicamentos homeopáticos para uso humano en dos dinamizaciones centesimales (7CH y 13CH) [(Silicea Terra (SiT), Natrum muriaticum (NaM), Zincum phosphoricum (ZiP) y Phosphoricum acidum (PhA)] y un tratamiento control (Agua destilada), sobre la germinación, emergencia y desarrollo vegetativo inicial del tomate. Los tratamientos se establecieron bajo un diseño completamente al azar con tres repeticiones. Se evaluó el porcentaje y tasa de germinación y emergencia, y variables morfométricas (altura de planta, longitud radicular, peso húmedo y seco). Además, en la etapa de desarrollo vegetativo se incluyeron las variables diámetro de tallo, peso húmedo y seco de hojas, número de ramas, hojas y brotes florales. Se observaron diferencias significativas en todas las variables morfométricas evaluadas, en función de las diferentes etapas de desarrollo, los medicamentos homeopáticos y sus diferentes dinamizaciones. Durante la germinación, se observó mayor crecimiento en longitud de tallo con ZiP-7CH (5.5±0.98 cm) en relación al grupo control (4.3±1.10 cm). Durante la etapa de emergencia, los tratamientos SiT-7CH (6.6±1.11 cm) y ZiP-7CH (5.9±1.41 cm) incrementaron significativamente la longitud del tallo, mientras que con PhA-7CH se obtuvieron los mejores efectos en la variables evaluadas durante la etapa de desarrollo vegetativo (LT (94±8.31 cm), N° hojas (131±27.71 hojas), BFT (17.20±2.45 g), BFH (30±7.72 g), BSH (2±0.61 g), BFR (10±6.26 g), BSR (1±0.43 g) y N° brotes florales (6±7.10 brotes)). Los medicamentos homeopáticos aplicados incidieron positivamente durante la etapa inicial y el desarrollo vegetativo del tomate, bajo condiciones controladas. Esta investigación representa un avance en el manejo sustentable del cultivo de tomate.

Title A name given to the resource Área superficial de carbones activados y modificados obtenidos del recurso agrícola Saccharum officinarum Creator An entity primarily responsible for making the resource Fredy Colpas C., Arnulfo Tarón D., Rafael González C. Description An account of the resource El carbón activado es un material utilizado industrialmente en adsorción de gases, filtrados, limpieza de líquidos y como soporte para catalizadores en medios no oxidantes. Además tiene varias aplicaciones ambientales como en la adsorción de iones metálicos de plomo. El objetivo de este trabajo fue la obtención de carbones activados carbonizando biomasa de caña de azúcar a 400°C en atmósfera de nitrógeno, activando con ácido fosfórico y oxidando con ácido nítrico o peróxido de hidrógeno seguido de tratamiento térmico. La preparación de carbones activados a partir de residuos agrícolas está desarrollándose con excelentes resultados potencialmente aplicables. Bajo este contexto, se muestra un método de preparación mediante activación química con ácido fosfórico, la cual aumentó el contenido de carbono y disminuyó el de oxígeno, seguidamente con el objeto de estudiar el desarrollo del área superficial se somete a proceso de oxidación con calentamiento térmico. Los carbones obtenidos fueron caracterizados mediante análisis proximal y para la determinación de los grupos funcionales oxigenados se utilizó la espectroscopia infrarroja de reflectancia difusa-transformada de Fourier. La determinación de grupos oxigenados básicos y ácidos se realizó por el método Boehm. Para la medición del área superficial se utilizó el método BET. El área de microporos se incrementó por el tratamiento con HNO3 y H2O2 desde 278 m2/g hasta 402 y 446m2/g, respectivamente. La mayor parte del área en los carbones se debió a los microporos. El pH de los carbones fue aproximadamente de tres y los grupos COOH alcanzaron valores hasta 2,12meq/g.

Title A name given to the resource Remoção de metais pesados tóxicos cádmio, chumbo e cromo em biofertilizante suíno utilizando macrófita aquática (Eichornia crassipes) como bioindicador = Removal of toxic heavy metals cadmium, lead and chromium from swine biofertilizer, using an aquatic macrophyte (Eichornia crassipes) as a bioindicator Creator An entity primarily responsible for making the resource Affonso Celso Gonçalves Júnior, Cleber Antônio Lindino, Mauricio Ferreira da Rosa, Reinaldo Bariccatti, Gilmar Divino Gomes Description An account of the resource Este trabalho objetivou avaliar a eficiência da macrófita aquática (Eichornia crassipes) como bioindicador e alternativa na remoção dos metais pesados tóxicos Cd, Pb e Cr em biofertilizante de origem suína. Foi utilizado o esquema fatorial 2x4, sendo os fatoresrepresentados pelas partes da planta (aérea e raiz), e pelos quatro tratamentos. Na instalação do experimento coletou-se uma alíquota da solução de cada tratamento para determinar as concentrações iniciais dos metais e, após 30 dias de cultivo, as plantas foram retiradas,coletando-se novamente uma alíquota da solução de cada tratamento. As plantas foram separadas em parte aérea e raiz, secas e trituradas. A macrófita apresentou-se eficiente na remoção dos metais pesados, observou-se que o sistema radicular da macrófita apresentoumaiores concentrações de Cd, Pb e Cr. Com este trabalho, conclui-se que a macrófita aquática (Eichornia crassipes) pode ser uma alternativa para o tratamento de biofertilizante e dejetos provenientes da suinocultura.The objective of this work was to evaluate the efficiency of an aquatic macrophyte (Eichornia crassipes) as a bioindicator and as an alternative sorbent for the removal of toxic heavy metals Cd, Pb and Cr from swine biofertilizer. A 2x4 factorial design was used, with the factors represented by plant parts (leaves and roots) and the fourtreatments. The metal concentrations were determined at the beginning of the experiment and after 30 days. The macrophyte showed good efficiency in the removal of toxic heavy metals from swine biofertilizer. It was observed that its radicular system presented larger amounts of Cd, Pb and Cr than did the leaves. Our results show that Eichornia crassipes could be an alternative treatment for biofertilizer and waste from swine culture.
