| O objetivo do presente trabalho foi comparar a eficiência dos métodos de estimativa da evapotranspiração de referência em relação ao método de FAO Penman-Monteith. Os dados meteorológicos utilizados foram coletados na estação meteorológica da rede do Iapar, instalada em Palotina, Estado do Paraná. Os dados utilizados, nas estimativas de evapotranspiração de referência, corresponderam ao período de 1994 a 2003. A evapotranspiração de referência foi estimada pelos métodos de Thornthwaite, Camargo e Hargreaves-Samani, sendo seu desempenho comparado ao método de FAO Penman-Monteith. As médias diárias da evapotranspiração de referência variaram entre 2,58 e 3,62 mm dia-¹. Os resultados indicaram que, para a escala diária, os métodos avaliados apresentaram bom... |

| ABSTRACT In the past decades, desert rose has become a very popular ornamental plant, especially among collectors, due to its exotic and sculptural forms. However, it has been grown on a commercial scale only recently, and little is known about how to best manage it as a container-grown plant, or even which potting medium (substrate) to recommend. Therefore, the aim of this study was to investigate the interactions between potting media and irrigation levels for growing desert rose as a potted ornamental plant. The experiment was conducted in a greenhouse using a 6 x 2 factorial arrangement with six replications, six potting media and two irrigation levels. The mixes were characterized by measuring their physical properties, specifically the density and... |

| Con la finalidad de conocer la respuesta del nopal verdura a la fertilización orgánica y química, incluyendo la inoculación de un hongo micorrícico y la frecuencia de riego, bajo condiciones de túnel de plástico. De 2010 a 2011 se evaluó el rendimiento y los parámetros de calidad: índice de color, pH, acidez titulable, textura, contenido de fibra y concentración nutrimental. Además de cuantificar el consumo de agua en una plantación de nopal verdura (Opuntia ficus indica L.). Para ello se utilizó un diseño experimental de parcelas divididas, donde en la parcela grande se estudió la frecuencia de riego cuando la tensión en el suelo era de 35 y 70 cb, y en la parcela dividida la fuente de fertilización (composta, inoculación del hongo micorrícico Glomus... |

| Irrigation is a practice widely used in fruit production in the Brazilian Northeast region, including in the papaya crop in order to increase their productivity. For the purpose of knowing the productive potential of papaya hybrid irrigated, an experiment was carried out in order to evaluate the performance of a papaya hybrid under different irrigations depths. Four irrigation depths (50, 75, 100 and 125% of ETo) were tested and the reference evapotranspiration was calculated by the Penman-Monteith model. The hybrid papaya used was UENF/Caliman 01, which was planted in single rows, spaced 4 x 2m from each other, and irrigated by dripping. The experimental design in randomized blocks was used with six replications and three plants per plot. The following... |

| Agroindustries are major consumers of water. However, to adapt to environmental trends and be competitive in the market, they have sought rational use of water through water management in their activities. Cleaner Production can result in economic, environmental and social benefits, and in actions that promote reduction in water consumption. This case study was conducted in a slaughterhouse and poultry cold storage processing plant and aimed to identify points of excessive water consumption, and to propose alternatives for managing water resources by reducing consumption. Consumption data are presented in relation to the processing stages with alternatives proposed for the rational use of water, such as closure of mains water during shift changes.... |

| 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... |

| Resumen Nos planteamos como objetivo poner de manifiesto las relaciones que se establecen entre los sectores productivos y el consumo de agua que éstos realizan para generar su producción. Aplicamos el estudio a Andalucía, Comunidad Autónoma del sur de España caracterizada por su escasez de agua, y nos preguntamos si la dependencia excesiva de los recursos hídricos que algunos sectores productivos de dicha Comunidad pueden llegar a tener, podría afectar de forma negativa, no sólo a la conservación y a la calidad del recurso, sino también a la sostenibilidad de la propia economía. Utilizamos una metodología mixta en la que combinamos el análisis Input-Output, con el que definimos un modelo de consumo de agua y a partir de él elaboramos una Matriz de... |

| ABSTRACT The experiment was conducted to study the effect of pure glycerin supplementation (GLYC) in the drinking water of broilers subjected to heat stress and feed restriction. Water with 0, 1, or 2% glycerin was provided ad libitum to broilers in six hours of feed restriction. The birds were housed in two environments: thermoneutral (TN) - 25 ° C, and cyclic heat stress (HS) - 12h with 250C, 6h with 320C, 3h of 250 to 320C and 3h of 320 to 250C. The experimental design was randomized in a factorial arrangement of 2 x 3 + 2, with three GLYC levels, two environments and one control group with ad libitum feeding each environment. When submitted to HS, broiler receiving 2% glycerin presented higher weight gain (WG), water consumption (WC), feed intake (FI)... |

| ABSTRACT Quantification of the drained volume is one of the difficulties involved in using weighing lysimeters. Typically, this volume is measured by accessing a moat at the base of a lysimeter. However, it is not feasible to install the moat in small devices. Thus, the aim of this study involves developing, installing, calibrating, and checking the efficiency of small weighing lysimeters with automated drainage systems to test their functionality in field conditions. Each lysimeter is composed of a round PVC water tank with a diameter of 1.22 m and a depth of 0.58 m that is placed over a metal frame with three electronic load cells with the nominal capacity of each cell corresponding to 500 kg. The drainage system is composed of a small reservoir with a... |

| The objective of this study was to analyze the behavior of three genetic groups of confined goats by image monitoring using nine unneutered goats of the Azul, Graúna and Moxotó genotypes. The experimental design was completely randomized, in a 3 × 3 factorial arrangement (genetic groups × periods - morning, afternoon and night), with three replications. Animals were monitored by video cameras placed at the ceiling of each stall for 10 days. There were interaction factors in the frequency of behavioral categories: interaction with the trough, self-cleaning, standing bipedally, social interaction, and other activities. Azul, Graúna and Moxotó native goats kept in the same environment under the same system of containment and feeding show different frequencies... |

| ABSTRACT SAFER (Simple Algorithm for Evapotranspiration Retrieving) is a relatively new algorithm applied successfully to estimate actual crop evapotranspiration (ET) at different spatial scales of different crops in Brazil. However, its use for monitoring irrigated crops is scarce and needs further investigation. This study assessed the performance of SAFER to estimate ET of irrigated corn in a Brazilian semiarid region. The study was conducted in São Desidério, Bahia State, Brazil, in corn-cropped areas in no-tillage systems and irrigated by central pivots. SAFER algorithm with original regression coefficients (a = 1.8 and b = –0.008) was initially tested during the growing seasons of 2014, 2015, and 2016. SAFER performed very poorly for estimating corn... |
