| El Módulo de riego Angamacutiro del Distrito de Riego 087 Rosario-Mezquite, Michoacán tiene una superficie de riego de 7,686.30 ha y 2,162 usuarios, con una distribución media por usuario de 3.60 ha/usuario. Se abastece de la presa Melchor Ocampo a través de los canales principales margen derecha e izquierda. Los cultivos principales son sorgo y trigo; y en menor superficie, maíz, cebada, avena y fresa. El volumen disponible resulta insuficiente para cubrir las necesidades de riego de los cultivos en la superficie de riego dominada, razón por la cual se propone la Modernización de la red de conducción y de distribución y la mejora de la aplicación del riego en parcela, mediante la aplicación del riego con tubería por multicompuertas. La modernización del... |

| Se evaluó el efecto de seis concentraciones de conidios de Penicillium digitatum con el objetivo de determinar la concentración óptima que permita 100% de infección en frutos de limón persa en postcosecha. El hongo se aisló de frutos de limón mexicano del estado de Colima, Méx. Cada concentración (1 x 105, 3 x 105, 5 x 105, 7 x 105, 9 x 105, 1 x 106 esporas mL-1), se colocó en heridas de 2 mm profundidad x 1mm de ancho, aproximadamente, hechas en frutos en etapa de madurez de corte. Las concentraciones 1 x 105 y 3 x 105 esporas mL-1 mostraron una incidencia de 33 y 50 % de infección, respectivamente, mientras que los frutos inoculados con 5 x 105, 7 x 105, 9 x 105 y 1 x 106 esporas mL-1 presentaron 100% de incidencia de la enfermedad. Asimismo, se... |

| Conventional wisdom in many agricultural systems across the world is that farmers cannot, will not, or should not pay the full costs associated with surface water delivery. Across Organisation for Economic Co-operation and Development (OECD) countries, only a handful can claim complete recovery of operation, maintenance, and capital costs; across Central and South Asia, fees are lower still, with farmers in Nepal, India, and Kazakhstan paying fractions of a U.S. penny for a cubic meter of water. In Pakistan, fees amount to roughly USD 1-2 per acre per season. However, farmers in Pakistan spend orders of magnitude more for diesel fuel to pump groundwater each season, suggesting a latent willingness to spend for water that, under the right conditions, could... |

| Monitoring of species and their ecosystem attributes is a fundamental requirement in applied ecology and conservation. However, landscape scale monitoring requires an immense effort and commitment, especially when species have a wide distribution or are migratory in nature. Participatory monitoring, whereby local communities are engaged, is increasingly being proposed to address landscape scale monitoring. Its implementation is met with many challenges related to finances, motivation of the local people, lack of trained manpower, and nondirect legal use of the species in question. It is of interest to determine what makes a participatory monitoring program interesting for locals to ensure their long term engagement. Using the unique 26-year program of... |

| ABSTRACT Several studies determined the theoretical and effective capacity of sugarcane harvesters. However, in field conditions, some variables affect sugarcane production and their effect on machine productivity is difficult to measure. The objective of this study is to analyze the correlation of the operational capacity of sugarcane harvesters with property size, sugarcane yield, total operation time of harvesters, and lost productive time. This correlation will be used to construct models that estimate machine capacity under different working conditions. Harvest data were collected from 41 farms with different sizes and rates of productivity, with the harvesting of 412,207 tons of sugarcane by eight harvesters. Property size was the variable that, in... |

| ABSTRACT Brazil is home to several plant species that exhibit potential for starch extraction. The arrowroot plant stands out owing to its South American origin. Arrowroot starch is especially important for fine confectionery, which is a high-value niche market. Thus, a small producer could benefit from the high prices of arrowroot starch. However, to have consistent production, the extraction should be performed using simple, safe, and inexpensive equipment. Starch extraction involves disintegration of the raw material under water, followed by the separation of fibrous bagasse from the starch–water suspension. This study presents an equipment design based on the concept of appropriate technology that is suitable for small producers to extract starch. A... |

| Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) or chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% or 2.0%) mutagens and their mutagenic effectiveness and efficiency were estimated in the M2 generation. The M3 generation was used to identify the most effective mutagen and dose for induction of mutations. The average effectiveness of EMS was much higher than γ-rays. The lowest dose of γ-rays (200 Gy) and the lowest concentration of EMS (0.5%) showed the highest mutagenic efficiency in all genotypes. Analysis of the M3 generation data based on parameters such as the variance ratio and the difference in residual variances derived from the model of Montalván and Ando indicated that... |

| ABSTRACT Selection of more productive carrot genotypes is fundamental for crop breeding programs aiming to increase productivity and reduce cost production. Thus, the aim of this work was to evaluate gains from direct selection and to measure its effects on other agronomic traits of interest in carrots. Thirty six carrot genotypes were evaluated in two experiments: the first, sown in the second half of November 2016 and the second one in the first week of March 2017. The experimental plots covered a useful area of 1.5 m2, in transversal rows and 0.10-m double spacing between single rows x 0.20-m between double rows in a randomized block design with 3 replicates. At 90 days, the incidence of leaf blight was evaluated using a note scale and 100 days after... |

| Este trabalho foi conduzido no Perimetro Irrigado de Bebedouro, Petrolina, PE, no período de setembro/dezembro de 1983. O trabalho constou da avaliação do manejo de água em três lotes distintos de colonos. Cada lote foi aleatoriamente distribuido dentro de uma mesma mancha de solo, de modo a contemplar as unidades 37 AA, 37 AB e 37 BB de selo do tipo Latossolo Vermelho-Amarelo. Selecionou-se a cultura do feijão caupi (Vigna sinensis) por ser uma cultura base neste período. Em cada lote, fêz-se três coletas de dados ao longo do ciclo fenológico do feijão, assim discriminadas: a primeira, em outubro (durante o estádio inicial de feijão) a segunda, em novembro (início de floração) e a terceira, em dezembro (final do ciclo). Constatou-se que as vazões médias... |
