A gender performance indicator for irrigation: Concepts, tools and applications AgEcon
van Koppen, Barbara.
Although gender issues are today a priority on the agendas of irrigation policy makers, interventionists, farm leaders and researchers, there is still a considerable gap between positive intentions and concrete action. An important but hitherto ignored reason for this is the lack of adequate generic concepts and tools that are policy-relevant and can accommodate the vast variation in irrigation contexts worldwide. The Gender Performance Indicator for Irrigation (GPII) aims to fill this gap. In any particular scheme, this tool diagnoses the gendered organization of farming and gender-based inclusion or exclusion in irrigation institutions. It informs irrigation agencies what they themselves can do for effective change-if necessary. The tool also identifies...

Accounting for water use and productivity AgEcon
Molden, David J..
This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level such as an irrigated field or household, a service level such as an irrigation or water supply system, and a water basin level that may include several uses. Water accounting terminology and performance indicators are developed and presented with examples at all the three levels. Concepts and terminologies presented are developed to be supportive in a number of activities including: identification of opportunities for water savings and increasing water...

Nascimento,Fábio Nunes do; Andrade Júnior,Aderson Soares de; Bastos,Edson Alves; Ribeiro,Valdenir Queiroz; Lopes,Alzeneide da Silva.
Abstract: The objective of this work was to evaluate the stalk yield, technological quality parameters, and sugar and alcohol productions in the first sugarcane (Saccharum officinarum) crop cycle, according to the response to N and K2O applications by subsurface drip fertigation. The experiment was carried out in a dystrophic Ultisol, in a randomized complete block design with four replicates. The treatments consisted of a 2X + 2X + 1 incomplete factorial arrangement with the application of 60, 80, 120, 160, and 180 kg ha-1 N and 60, 80, 120, 160, and 180 kg ha-1 K2O. The maximum estimated yield (217.5 Mg ha-1) was obtained with the application of 180 kg ha-1 N and 60 kg ha-1 K2O. Sugar and alcohol productions increased with N application above 120 kg...

Agronomic aspects of soybean plants subjected to deficit irrigation AGRIAMBI
Nunes,Antônia C.; Bezerra,Francisco M. L.; Silva,Roberta A. e; Silva Júnior,José L. C. da; Gonçalves,Flávia B.; Santos,Geovana A..
ABSTRACT This study aimed to evaluate the behavior of soybean plants subjected to irrigation management with controlled water deficits in different phenological stages. The research was conducted in an experimental area of the Federal University of Tocantins (UFT), in Palmas-TO, Brazil. The experimental design was randomized blocks with four replicates, and treatments arranged in a split-plot scheme. The plots consisted of irrigation levels that induced plants to water deficit in the vegetative stage, reproductive stage and throughout the entire cycle, based on potential crop evapotranspiration (ETpc). The subplots corresponded to two soybean cultivars (M9144RR and TMG1288RR). The following agronomic variables were evaluated: days until flowering, days...

AGRONOMIC PERFORMANCE OF RADISH GENOTYPES UNDER DIFFERENT IRRIGATION DEPTHS REA
Cunha,Fernando F. da; Souza,Ivan P. de; Campos,Washington de O.; Andrade Júnior,Valter C. de; Magalhães,Thiago A..
ABSTRACT In radish production, the choice of proper genotypes and irrigation regime is of great importance to achieve success. In light of this, the current study aimed to evaluate the agronomic performance of a few radish genotypes under different irrigation strategies. The plants were grown in the city of Unaí - MG, in Brazil, under field conditions, and during two cycles, one of 40 days (from February 28 to April 8, 2015) and other of 51 days (from May 9 to June 28, 2015). The experimental design was a randomized block design in a split-plot arrangement with four replications. The treatments consisted of four irrigation strategies (50, 75, 100, and 125% of crop evapotranspiration - ETc) applied by a dripping irrigation system, while subplots consisted...

Agronomic performance of the cowpea under different irrigation depths and row spacing Rev. Ciênc. Agron.
Costa Junior,Manoel de Jesus Nunes da; Bastos,Edson Alves; Cardoso,Milton José; Andrade Júnior,Aderson Soares de.
ABSTRACT The cowpea is of great socioeconomic importance in the North, Northeast and Mid-West of Brazil, and its irrigated farming has recently been on the increase in these regions. The aim of this study was to evaluate the agronomic performance of the cowpea 'BRS Tumucumaque' for different row spacings and irrigation depths, under the conditions of soil and climate of Teresina, in the State of Piauí. The experiment was carried out from August to November 2014, in a Yellow Argisol at the Experimental Area of Embrapa Meio-Norte in Teresina. The experimental design was of randomised blocks in subdivided lots, with four replications. The treatments consisted of five irrigation depths (40% ETo, 70% ETo, 100% ETo, 130% ETo and 160% ETo) in the main plot, and...

Alternative reference evapotranspiration methods for the main climate types of the state of Paraná, Brazil PAB
Gurski,Bruno César; Jerszurki,Daniela; Souza,Jorge Luiz Moretti de.
Abstract: The objective of this work was to define the best alternative methods for estimating the reference evapotranspiration (ETo) in the main climatic types (Cfa and Cfb) of the state of Paraná, Brazil. The methods tested were Budyko, Camargo, Hargreaves-Samani, Linacre, and Thornthwaite, which were compared to the ETo calculated with the Penman-Monteith ASCE (EToPM) method, between 1986 and 2015, in eight meteorological stations. The performance of the alternative methods was obtained from the coefficient of determination (R2), index “d” of agreement, index “c” of performance, and root mean square error (RMSE). The Hargreaves-Samani method has a better performance in estimating the ETo for the main climatic types in the state of Paraná. The Camargo...

Objetivou-se avaliar o desempenho do método Penman Monteith parametrizado no boletim 56 da FAO (PM-FAO56) com ausência de dados, e de métodos alternativos para a estimativa da evapotranspiração de referência no Submédio Vale do São Francisco. Foram utilizadas as variáveis meteorológicas do período de março de 2003 a abril de 2008, de cinco estações automáticas pertencentes à rede da Embrapa Semiárido. Na avaliação desse método foram consideradas diferentes combinações quanto à ausência de medição de variáveis meteorológicas (saldo de radiação, radiação solar global, temperatura e umidade relativa do ar, e velocidade do vento), e os métodos alternativos de Hargreaves e Samani, Jensen e Haise e Makkink. O desempenho foi analisado por meio de índices e erros...

Capacitive probe calibration in eutroferric red nitosol cultivated with irrigated forages. Repositório Alice
SANCHES, A. C.; SOUZA, D. P. de; JESUS, F. L. F. de; MAFFEI, R. G.; MENDONÇA, F. C.; PEZZOPANE, J. R. M..
Knowledge of soil water content is important for proper irrigation management because it allows estimating the required amount of water to be applied at the correct time. Capacitance sensors are an alternative of quantification of soil water content (?, cm3 cm-3 ), providing depth readings in a practical and fast way. A capacitive probe (Diviner 2000®) was calibrated in a eutroferric red nitosol cultivated with irrigated forages at the experimental area of ESALQ/USP in the city of Piracicaba - SP, Brazil. Four access tubes were installed and every 2 weeks samples were collected with 3 replicates for each depth level, by the end of 8 weeks starting from ?saturated. Readings were taken with the equipment for every 0.1 m of soil up to 0.7 m of depth, together...
