“…For the authors Lopes et al (2019), declining irrigation was more uniform (CUC = 99.03% and CUD = 98.45%), however, for all the studied graphs, it was out of statistical control, unlike the data found in this work. They reached higher values of excellence in irrigation, but without statistical control.…”

Solar energy is a clean and renewable energy production option and can be applied to pumping water. Pumping water with photovoltaic solar energy is one of the technologies that has stood out in the country. In this context, the work aimed to evaluate the different methods of a drip irrigation system as a function of the use of an indoor amorphous photovoltaic pumping system, without electrical energy storage. The study was installed at the State University of Western Paraná. Voltage and current data were generated by the photovoltaic panels; solar irradiation was measured by the pyranometer device; the water pump flow rate was determined using the flow meter and in-line drip tube types. Irrigation performance was determined by the water distribution uniformity coefficients (CUD) and Christiansen’s uniformity coefficient (CUC). Tests were performed on open and partially cloudy days. The experiment totaled 40 sampled data, half being collected on sunny days and the other half on partially cloudy days, at 9:45 am; 11:00 am; 1:30 pm and 3:00 pm. The methodology had the greatest influence on the CUD value. For the CUC parameter, the values were approximately 89% for the studied methods. Values remained under control for the Shewhart graph, but with the process capacity index affected.

“…Treatment N (kg ha -1 ) K (kg ha -1 ) P (kg ha (1942) to calculated the system uniformity of overlapping sprinklers. However, some previous studies have successfully used it in furrow irrigation (Kang et al, 2000), drip irrigation (Lopes et al, 2019), and micro-irrigation (Kumar et al, 2009) systems. The CU can also be used to quantify the uniformities of plant height (Zhao et al, 2012), soil water content with depth (Kang et al, 2000), nitrogen uptake (Guan et al, 2013), soil nitrogen (Zhou et al, 2018).…”

This study aimed to evaluate the uniformity of a drip fertigation system with liquid peats on different slopes. The experiment was carried out on a test bench, where the flow rate of the drippers was determined and subsequently its uniformity was calculated using the Christiansen uniformity coefficient (CUC) fot the treatments in level (0%), uphill (2%) and downhill (2%). The experimental statistics were performed by analysis of variance (ANOVA) and Tukey’s test at 5% probability to compare uniformity, in addition to the analysis of the process by Shewhart and CUSUM control charts. Liquid peat showed excellence in its uniformity (>90%) while used for drip irrigation systems. The liquid peat applied at the level slope was the most uniform, followed by upslope and downslope treatments, respectively. Through Shewhart and CUSUM control charts, it was possible to affirm that fertigation with liquid peat in level obtained a better performance.

UNIFORMIDADE DE SISTEMA DE IRRIGAÇÃO POR GOTEJAMENTO COM TURFA LÍQUIDA EM DIFERENTES INCLINAÇÕES 2 RESUMO O uso da turfa líquida é uma alternativa ao uso da fertirrigação mineral. No entanto, é necessário o monitoramento da uniformidade deste fertilizante organomineral para obter seu uso adequado, assim o fertilizante organomineral pode produzir culturas de melhor qualidade. O objetivo deste estudo foi avaliar a uniformidade de um sistema de fertirrigação por gotejamento com turfa líquida em diferentes inclinações. O experimento foi conduzido em uma bancada de testes, onde a vazão dos gotejadores foi determinada e consequentemente sua uniformidade pelo Coeficiente de uniformidade de Christiansen (CUC) para os tratamentos em nível (0%), aclive (2%) e declive (2%). A estatística experimental foi determinada pela análise de variância (ANOVA) e teste de Tukey a 5% de probabilidade na comparação da uniformidade, complementando os gráficos de controle de Shewhart e CUSUM. A turfa líquida apresentou excelência na sua uniformidade (> 90%) em sistemas de irrigação por gotejamento. A turfa aplicada em nível (0%) foi a mais uniforme, seguido pelos tratamentos em aclive e declive, respectivamente. Através dos gráficos de controle de Shewhart e CUSUM foi possível afirmar que a fertirrigação em nível obteve uma melhor performance. Palavras-chave: gráficos de controle, uniformidade, fertilizante organomineral, microirrigação.
