Distribution Uniformity

Developing an appropriate irrigation schedule is essential in order to save water while at the same time maintaining high crop yields. The standard procedures of the field evaluation of distribution uniformity do not take into account the effects of the filling and emptying phases of the irrigation system. We hypothesized that, in sloping sandy soils, when short drip irrigation pulses are applied it is important to take into account the total water applied from the beginning of irrigation until the emptying of the irrigation system. To compute distribution uniformity, we sought to characterize the filling, stable pressure, and emptying phases of a standard strawberry irrigation system. We found that the shorter the time of the irrigation pulse, the worse the distribution uniformity and the potential application efficiency or zero deficit are. This effect occurs because as the volume of water applied during filling and emptying phases increases, the values of the irrigation performance indicators decrease. Including filling and emptying phases as causes of non-uniformity has practical implications for the management of drip irrigation systems in sloping sandy soils.

AVALIAÇÃO DO DESEMPENHO DE SISTEMAS DE IRRIGAÇÃO POR ASPERSÃO CONVENCIONAL FIXO E GOTEJAMENTO EM VILA RURAL  Eguimar Amorim Maciel de Souza; Paula Cristina de Souza; Márcio Antônio Vilas BoasCentro de Ciências Exatas e Tecnológicas, Universidade do Oeste do Paraná,  Cascavel , Pr, [email protected]  1 RESUMO           O manejo racional da irrigação consiste na aplicação da quantidade necessária de água às plantas no momento correto. É recomendável após a instalação de um sistema de irrigação, proceder-se a testes de campo, com o objetivo de se verificar a adequação da irrigação recomendando, quando necessário, ajustes na operação e, principalmente, no manejo. O propósito deste trabalho foi avaliar dois sistemas de irrigação, sendo um por aspersão convencional fixo e outro por gotejamento,  implantados na Vila Rural Flor do Campo, localizada na região Noroeste do Estado do Paraná, através da determinação dos parâmetros de uniformidade e eficiência de distribuição de água.  Foram utilizadas as metodologias propostas na norma ABNT NBR ISO 7749-2, Asae (1995) e por Keller & Karmeli (1975).   Foram realizados trinta ensaios em cada sistema de irrigação. Para o sistema de irrigação por aspersão foi obtido  CUC  de 77,9%, considerado abaixo do valor mínimo aceitável de 80%, sendo que  a velocidade do vento variou de 0 a 2,4 m s-1. As eficiências de aplicação (Ea) e armazenagem (Es) obtidas neste sistema foram, respectivamente, de 77,0% e 48,8%. No sistema de irrigação por gotejamento foi obtido CUC de 93,7% considerado valor excelente. A Uniformidade de Emissão (UE) encontrada foi de 89,3% sendo considerada boa. As eficiências de aplicação (Ea) e armazenagem (Es) obtidas neste sistema foram, respectivamente, de 100% e 65,0 %. UNITERMOS: Irrigação, aspersão convencional, gotejamento,       uniformidade, eficiência,  avaliação.  SOUZA, E.

PERFORMANCE EVALUATION OF FIXED CONVENTIONAL ASPERSION AND DRIPPING IRRIGATION SYSTEMS IN  A RURAL VILLAGE  2 ABSTRACT The rational handling of the irrigation consists of the application of the necessary amount of water to the plants at the correct moment. After the installation of an irrigation system, it is recommended the field tests be carried out in order to  verify the adequacy of the recommended irrigation and , when necessary, to adjust the operation and, mainly, the handling. The aim of this work was to evaluate two irrigation  systems,  a fixed conventional aspersion system and a dripping one, installed in the l Flor do Campo, a rural village located in the Northwest of Paraná state, through the determination of the parameters of water distribution uniformity and efficiency. The methodologies used were according to the  ABNT NBR ISO 7749-2 norm, Asae (1995) and for Keller & Karmeli (1975). Thirty assays in each irrigation system were tested. In the irrigation system with  aspersion CUC of 77.9%, which is considered below the minimum acceptable value of 80%, was found  considering that the wind speed varied from   0 to  2.4 ms-1. The efficiencies of application (Ea) and storage (Es) obtained in this system were 77.0% and 48.8 %, respectively. In the dripping  irrigation system, a CUC of 93.7%, considered an excellent value,  was found. The EU was 89.3% and considered good. The efficiencies of application (Ea) and storage (Es) gotten in this system were  100% and 65. 0 %, respectively. KEY WORDS: Irrigation, conventional aspersion, dripping, uniformity, efficiency, evaluation.

And Control

Sprinkler irrigation systems are widely used in medium and large scale farms in different forms. However less types are available to apply in small farms due to their high costs. The current study was done according to a novel cost effective design for a semi-permanent sprinkler irrigation system for small farm owners. The new layout known as Corner Pivot Lateral (CPL) was examined in irrigation test center at Lijian Scientific and Technological Demonstration Park, at Nanning city, China. CPL was implemented without a main/sub mainline pipe, by applying a single pivoting lateral at the corner of the plot that directly connected to the resource to convey water from the pump. The lateral moves around the corner using a rotating elbow in a quadrant pattern manually to cover the entire farm. A conventional semi-permanent system was applied for the same farm as reference. A cost analysis on the required components as well as annual operational costs was carried out for comparison and control. Results showed that a lower system component would be needed for the CPL method. Overall, more than a 15% capital cost reduction with 7% annual cost decrement was achieved for CPL in this experiment comparatively. The Catch can technique was applied to examine the CPL system’s efficiency and 79% water distribution uniformity around the sprinkler was obtained. This new method can encourage small estate holders to switch from traditional to pressurized systems which optimizes water application costs.

Frequent Problem

Many producers use drippers for trickle irrigation systems for flower production in the field and in protected environments. A frequent problem in this type of irrigation system is the clogging of drippers, which is directly related to water quality and filtering system efficiency. The objective of this study was to conduct an experimental investigation to evaluate the efficiency of using nitric acid and sodium hypochlorite to unclogg drippers due to the use of water with high algae content. The evaluation was conducted in six, 4216 m² greenhouses, each with two sectors comprised of ten spaces or lines, totaling 12 sectors of a dripper irrigation system in a rose producing property of Holambra, State of SP, Brazil. Chemical and physical analyses and the bacteriological count in water were carried out in the three water sources that supply the irrigation system to check the factors causing the clogging. Evaluations were carried out on water distribution uniformity in all sectors before and after chemical treatment in order to evaluate efficiency. The treatment improved water distribution uniformity and a lead to a reduction in the coefficient of variation (CV) for dripper flow in all sectors. There was a good correlation between CV and the water distribution uniformity index. Therefore, this is an excellent method to be used to unclogg drippers due to biological problems.
