Title A name given to the resource Desempenho econômico da cultura do girassol em sistemas de agricultura familiar do sudeste paranaense Economic performance of sunflower in family farming systems of southeastern Paraná, southern Brazil Creator An entity primarily responsible for making the resource Maria de Fátima dos Santos Ribeiro, Augusta Pelinski Raiher Description An account of the resource O objetivo deste trabalho foi avaliar o desempenho econômico da cultura do girassol em sistemas de produção familiar do sudeste paranaense. Foram avaliadas 26 situações culturais, as quais variaram quanto às condições edafoclimáticas, à intensidade de uso de mecanização, ao custo com fertilizantes e à cultivar utilizada. A Análise de Componentes Principais indicou que o desempenho econômico da cultura do girassol não esteve correlacionado com a intensidade de uso de mecanização, sendo possível auferir maiores margens brutas, tanto em sistemas totalmente mecanizados, quanto em sistemas com mecanização intermediária ou com tração animal. O custo com fertilizantes e a produtividade foram os fatores mais importantes para o desempenho econômico da cultura. Verificou-se também que o custo com sementes não esteve correlacionado com a margem bruta. Assim, para as condições do presente estudo, é economicamente mais interessante a utilização de materiais com alto potencial produtivo, mesmo que o custo de aquisição das sementes seja maior. Pela Análise de Cluster, as 26 situações culturais foram agrupadas em quatro classes de desempenho econômico. As menores margens brutas variaram entre R$180 ha-1 (sistema totalmente mecanizado) e R$288 ha-1 (tração animal e intermediário). As maiores margens brutas variaram entre R$553 ha-1 (sistema totalmente mecanizado) e R$695 ha-1 (tração animal e intermediário).This study aimed to evaluate the economic performance of sunflower in family farms of the Southeastern region of Paraná. Twenty-six situations were evaluated, according to the agroecological conditions, the different levels of mechanization, the amounts of fertilizer applied and varieties. Principal Component Analysis showed that the economic performance was not correlated to the level of mechanization. It was possible to obtain higher gross margins in intensive mechanization, intermediate or animal traction systems. Among the factors that comprise the gross margin, costs with fertilizers and crop yields were those of more importance for the economic performance. On the other side, as the seed costs was not correlated with the gross margin, for the conditions of this study, from the economic perspective it is more interesting the use of high-yielding varieties, even if the cost is higher. Cluster Analysis grouped the 26 situations into four classes of economic performance. The lowest gross margins ranged from R$180 ha-1 (totally mechanized) and R$288 ha-1 (intermediate and animal traction). The highest gross margins ranged from R$553 ha-1 (totally mechanized) and R$695 ha-1 (animal traction and intermediate).

Title A name given to the resource Crescimento inicial do milho sob diferentes concentrações de biofertilizante bovino irrigado com águas salinas Initial growth of corn plants subjected to different concentrations of biofertilizer and irrigated with saline water Creator An entity primarily responsible for making the resource Geocleber Gomes de Sousa, Albanise Barbosa Marinho, André Henrique Pinheiro Albuquerque, Thales Vinícius de Araújo Viana, Benito Moreira de Azevedo Description An account of the resource O objetivo deste trabalho foi avaliar o efeito da irrigação com água de alta e baixa salinidade sob o crescimento inicial de plantas de milho cultivadas em solo adubado com biofertilizante bovino. O experimento foi conduzido em ambiente telado do Departamento de Ciências do Solo - UFC. O plantio das sementes deu-se em vasos com capacidade de 12 kg, contendo como substrato um Argissolo e uma planta por vaso. O experimento obedeceu a um delineamento experimental inteiramente casualizado, em esquema fatorial 5 x 2, com quatro repetições, referentes a cinco concentrações de biofertilizante: C1 = 50% bio + 50% água (1:1), C2 = 33,33% bio + 66,67 água (1:2), C3 = 25% bio + 75% água (1:3), C4 = 20% bio + 80% água (1:4) e C5 = 11,12+ 88,88% água (1:5) e dois níveis de salinidade para a água de irrigação S1 = 0,8 dS m-1 (baixa salinidade) e S2 = 3,4 dS m-1 (alta salinidade). Foram analisadas a condutividade elétrica do solo (CEes) e o crescimento inicial das plantas utilizando-se as seguintes características: altura de plantas, diâmetro do colmo, área foliar, matéria seca da parte aérea, da raiz e matéria seca total. A irrigação com água de baixa salinidade foi mais eficiente no crescimento inicial das plantas, exceto a matéria seca da raiz, sob concentrações crescentes de biofertilizante bovino. Sob as mesmas concentrações de biofertilizante bovino e irrigação com água salina, elevou o caráter salino do solo, mas com menos intensidade no solo irrigado com água de baixa salinidade.The purpose of this study was to evaluate the effect of irrigation with water of high and low salinity on the initial growth of corn plants grown in soil fertilized with bovine bio-fertilizer. The experiment was conducted in a greenhouse of the Department of Soil Science - UFC. The seeds were planted in vessels with a 12 kg capacity, containing Alfissol as substrate and one plant per pot. The experiment followed a completely randomized design, in a 5x2 factorial scheme, with four replications, referring to five concentrations of bio-fertilizer: C1 = 50% biofertilizer + 50% water (1:1), C2 = 33.33% biofertilizer + 66.67 + water (1:2), C3 = 25% biofertilizer + 75% water (1:3), C4 = 20% biofertilizer + 80% water (1:4) and C5 = 11.12% biofertilizer + 88, 88% water (1:5) and two salinity levels of irrigation water for S1 = 0.8 dS m-1 (low salinity) and S2 = 3.4 dS m-1 (high salinity). We analyzed the early growth of plants as compared to the readings of electrical conductivity of water saturated soil extracts (ECse) by using the collected data on plant height, stem diameter, leaf area, shoot dry matter, root dry matter and total dry matter. Irrigation with low salinity water was found more efficient in promoting the initial growth of plants under increasing concentrations of biofertilizer, except for root dry matter. Under the same concentrations of biofertilizer, plus irrigation with saline water, soil salinity increased, but did so with less intensity in soil irrigated with low salinity water.

Title A name given to the resource A expansão da disponibilidade de crédito PRONAF às comunidades quilombolas do Vale Do Ribeira/SP como expressão da crise imanente do capital Creator An entity primarily responsible for making the resource Cecília Cruz Vecina Description An account of the resource The purpose of this paper is to discuss some understandings about the process of capital accumulation (mainly formulated by David Harvey, 2011, and Roswitha Scholz, 2016) through the study of the rise in the quantities of contracts and resources released nationally by the “Programa Nacional de Fortalecimento da Agricultura Familiar” (PRONAF) over the governments of Luiz Inácio Lula da Silva (2003-2010) and Dilma Rousseff (2011-2016) and their distribution history to the quilombola communities in the Vale do Ribeira/SP. This articulation, between the reproduction of capital in its totality, the national economic policy and the particularity of social relations in the quilombola communities, becomes important as a form of analysis that puts these plans in tension, which, we argue, makes it possible to make explicit the limits of accumulation and of the actions taken to circumvent the phenomenal crises of capital. Thus, based on fieldwork conducted between 2015 and 2018 in the cities of Eldorado, Iporanga and Registro (in which we interviewed quilombola farmers, agricultural technicians from the “Fundação Instituto de Terras do Estado de São Paulo” - ITESP -, the “Coordenadoria de Assistência Técnica Integral” - CATI - and financial agents of Banco do Brasil), we sought to present the relationship between access to credit and the promise of “enrichment” that this represents for quilombola families, how the subjects involved understand when defaulting and the relations between these process and the totality given by the reproduction of the capital in general.

Title A name given to the resource Resposta do algodoeiro a diferentes doses de bioestimulante aplicado via semente Creator An entity primarily responsible for making the resource Eduardo Pradi Vendruscolo, Epitácio José de Souza, Sebastião Ferreira de Lima, Osvaldir Feliciano dos Santos Description An account of the resource A realização deste trabalho teve por objetivo avaliar a ação de diferentes doses de biorregulador, aplicado via semente, sobre o desenvolvimento inicial do algodoeiro (Gossypium hirsutum L.). O trabalho foi conduzido em casa de vegetação localizada na Universidade Federal de Mato Grosso do Sul - UFMS, Campus de Chapadão do Sul, onde sementes de duas cultivares de algodoeiro (FMT 701   e FMT 705) foram expostas a seis diferentes doses de biorregulador vegetal (0,0; 5,0; 10,0; 15,0; 20,0 e 25,0 mL 0,5 kg-1 de sementes). Foram avaliadas as massas frescas e secas da folha, caule e raiz. Também foi avaliado o crescimento da planta, medindo-se a altura e o diâmetro a cada sete dias, até 49 dias de idade da planta.  A cultivar FMT 701 apresentou maiores incrementos em matéria fresca e seca de folha, caule e raiz. Apenas a cultivar FMT 705 apresentou variações significativas para a variável diâmetro de caule, a qual teve incremento positivo até o diâmetro máximo de 3,07 mm, correspondente à dose de 7,83 mL biorregulador 0,5 Kg-1 de sementes, também as plantas pré-embebidas com 10 mL 0,5 Kg-1 de sementes apresentaram um incremento em altura de 2,34% em relação à testemunha e 21,29% sobre as plantas pré-embebidas com 25 mL 0,5 Kg-1 de sementes. Concluiu-se que a cultivar FMT 701 se mostrou mais suscetível à aplicação do biorregulador e a dose de biorregulador 10 mL 0,5 Kg-1 de sementes proporcionou o melhor estabelecimento inicial do algodoeiro, nas condições do experimento.

Title A name given to the resource Producción de Bioetanol a partir de Elodea sp. Creator An entity primarily responsible for making the resource Tatiana Marulanda López, Luisa Fernanda Zapata Osorno, María Consuelo Jaramillo Flórez Description An account of the resource La dependencia de los países a los combustibles fósiles es cada vez mayor, pero estos no son renovables. Además, el uso de estos combustibles ha aumentado la emisión de gases de efecto invernadero. Colombia debe empezar a buscar otras alternativas que suplan la deficiencia en combustible, y cuya fuente de obtención sea renovable y no comprometa los recursos agrícolas usados como alimentos, tal es el caso de la caña de azúcar. Las plantas invasoras se caracterizan por producir eutrofización de las aguas, ocasionando problemas ambientales y de abastecimiento de agua a las ciudades. El manejo que se hace de esta planta es erradicarla usando diferentes métodos. En este artículo se muestra el aprovechamiento de la planta invasora de cuerpos acuosos, Elodea sp., para la obtención de bioetanol. Después de la hidrólisis de los carbohidratos, la detoxificación, y la fermentación, la planta mostró un alto rendimiento en la producción de bioetanol. Este trabajo es la base para el desarrollo del bioproceso, usando como sustrato el material lignocelulítico, y además, es una alternativa para el manejo de la planta Elodea sp. bomo fuente de energía carburante.

Title A name given to the resource Características agronômicas do amendoinzeiro sob irrigação com águas salinas em solo com biofertilizantes = Agronomics Characteristicsof Peanuts under irrigation with saline water on soil with biofertilizers. Creator An entity primarily responsible for making the resource Geocleber Gomes de Sousa, André Henrique Pinheiro Albuquerque, Thales Vinícius de Araújo Viana, Benito Moreira de Azevedo, José Bruno Rego de Mesquita Description An account of the resource Objetivou-se com esse trabalho avaliar o efeito da salinidade da água de irrigação nas características agronômicas do amendoinzeiro (Arachis hypogaea L.) cultivado em solo sem e com biofertilizantes. O experimento foi conduzido em estufa telada na Estação Agrometereológica, Campus do Pici, Fortaleza, CE. A semeadura foi feita em vasos utilizando-se, como substrato, um Argissolo Vermelho-Amarelo, com uma planta por vaso. O experimento obedeceu a um delineamento inteiramente casualizado, em esquema fatorial 4 x 3, com cinco repetições. Os fatores referem-se aos valores de condutividadeelétrica da água de irrigação: 1,5; 3,0; 4,5 e 6,0 dS m-1 e sem e com biofertilizantes (sem biofertilizante -B0; com biofertilizanteanaeróbico-B1; e com biofertilizante aeróbico - B2). Foram avaliadas as seguintes variáveis: pH, condutividade elétrica do solo, crescimento inicial em número de folhas, altura de plantas, diâmetro do colmo, área foliar e matéria seca da parte aérea. O biofertilizante bovino diminuiu os efeitos negativos das concentrações crescentes de sais na água de irrigação nas variáveis estudadas. O nível salino do solo foi maior na presença do biofertilizante anaeróbico. O biofertilizante anaeróbico foi mais eficiente que o aeróbico na redução dos efeitos depressivos dos sais das águas de irrigação às plantas.This study evaluated the effects of irrigation water salinity on agronomics characteristics of peanut (Arachis hypogaea L.), cultivated without and with biofertilizers. The experiment was conducted in a greenhouse in the Estação Agrometereológica, Campus do Pici, Fortaleza, CE. The seeds were sown in pots using, as substrate, a Red-Yellow Argisol, with one plant per pot. The experiment followed a completely randomized design set as a 4 x 3 factorial, referring to four irrigation water electrical conductivity values: 1.5, 3.0, 4.5 and 6.0 dS m-1 in three soil configurations: B0(without biofertilizer), B1 (with anaerobic biofertilizer) and B2 (with aerobic biofertilizer), with five repetitions. The following variables were evaluated: pH, soil electrical conductivity, initial growth in number of leaves, plant height, stem diameter, leaf area and dry shoot mass. The bovine biofertilizer reduced the negative effects of increasing saline concentration in irrigation water in the variables evaluated.The soil salinity level was higher in the presence of anaerobic biofertilizer. The anaerobic biofertilizer was more efficient thanaerobic biofertilizer in reducing the depressive effects (to plants) of irrigation water salts.

En los sistemas agrícolas convencionales se realiza un mayor aporte de nitrógeno (N) que en los ecológicos; en estos, por otro lado, el aporte de materia orgánica es mucho mayor que en los convencionales. La consecuencia lógica sería de esperar un mayor contenido de N en los suelos de cultivos convencionales, y un mayor contenido de materia orgánica en los suelos de cultivos ecológicos. Sin embargo, los resultados de porcentaje de carbono (C) (representativo en materia orgánica) obtenido en este estudio no corroboraron la teoría, porque la principal diferencia se encontró en la gestión de regadío y secano, independientemente de si se trataba de sistemas convencionales o ecológicos. La mayor disponibilidad de nitrógeno se encontró en los suelos de gestión de regadíos ecológicos.

A partir dessas preocupações, o estudo objetivou observar as alterações das propriedades físicas e químicas do solo (granulometria e densidade aparente) bem como avaliar as modificações ocorridas na sua morfologia e como a forma de manejo influencia nos processos hidroerosivos associando este à pluviosidade durante o período do verão 2009/2010. O trabalho foi realizado na Estação Experimental da PESAGRO, Paty do Alferes - RJ, composta por três áreas experimentais: 1) Sem Cobertura (SC), 2) Plantio convencional (PC) e 3) Cultivo Mínimo (CM). O sistema Cm apresentou menor DAP em superfície (1,09 g/cm³), conectividade poral e quantificação poral mais homogênea (32,8%; 33,1%; 33,3%) e maior teor de C-Total (5,1%) em detrimento aos outros dois usos, demonstrando a importância da manutenção da estrutura do solo, através de um manejo conservacionista.

Title A name given to the resource Eficiencia técnica en la agricultura familiar: Análisis envolvente de datos (DEA) versus a proximación de fronteras estocásticas (SFA) Creator An entity primarily responsible for making the resource Ramiro Rodríguez Sperat, María Pía Brugiafreddo, Erica Raña Description An account of the resource El presente trabajo estudia la eficiencia técnica en la agricultura familiar, tomando como caso de estudio las explotaciones que producen leche de cabra en la cuenca lechera caprina de Santiago del Estero, y utilizando el Análisis Envolvente de Datos (DEA) y la Aproximación de Fronteras Estocásticas (SFA). En relación a la eficiencia de los productores estudiados, se observa que la cuenca lechera caprina de Santiago del Estero cuenta con índices de eficiencia técnica promedio de 0.567 (utilizando DEA CRS), 0.693 (utilizando DEA VRS) y 0.745 (utilizando SFA). Mediante la comparación de los resultados se observa que no existirían diferencias en los resultados entre DEA (VRS) y SFA, en cambio si se observan diferencias al comparar los resultados de DEA (CRS) y SFA. En ese marco, no se encontraron fundamentos para utilizar uno u otro método para los estudios de eficiencia en la agricultura familiar, debiéndose tomar la decisión de que método utilizar para cada caso en particular, de acuerdo al tipo de información disponible, la formación de cada investigador y la aplicación que se busque dar a los resultados.
