Resumo: | Irrigation systems must be assessed periodically to verify equipment quality and the need for adjustments. For this, precipitation test kits are necessary. However, commercially available kits have as their main disadvantage the high cost. Therefore, this study aimed to develop an alternative low-cost precipitation kit and verify its efficiency compared to an available commercial brand. The validation test was carried out at the Laboratory of Hydraulics of the Federal University of Viçosa (UFV) using a conventional sprinkler system organized in a quadrangular arrangement. Water collections were carried out within two hours using a grid of plastic collectors spaced at 3 × 3 m and installed at 0.7 m above the ground. The coefficient of determination (R2), uniformity coefficients, application efficiency, and thematic maps of the spatial variability of the applied irrigation depth were compared between kits and used for the validation of measurements. The results showed a high agreement between the developed (GESAI) and a commercial kit (Trademark) (R2 = 0.9849), and a high spatial agreement between the collected water depths. Therefore, the GESAI kit is a low-cost alternative for the assessment of irrigation systems. |

Para isso, kits de ensaios de precipitação são necessários, entretanto, os kits comercialmente disponíveis apresentam como principal desvantagem o elevado custo. Assim, o presente trabalho teve como objetivo elaborar um kit de precipitação alternativo de baixo custo e averiguar a sua eficiência frente a marca comercial disponível. O ensaio de validação foi realizado no Laboratório de Hidráulica da Universidade Federal de Viçosa (UFV), utilizando um sistema de aspersão convencional, disposto em um arranjo quadrangular. As coletas de água foram realizadas no período de duas horas, com auxílio de uma malha de coletores plásticos espaçados em 3 x 3 m e instalados a 0,7 m acima do solo. Para comparação e validação das medições foram utilizados o coeficiente de determinação (R²), coeficientes de uniformidade, eficiência de aplicação e mapas temáticos da variabilidade espacial da lâmina aplicada entre os kits. Os resultados mostraram que houve elevada concordância entre o kit desenvolvido (GESAI) e o kit comercial (Trademark) (R² = 0,9849) e uma concordância espacial elevada entre as lâminas coletadas. Portanto, recomenda-se o uso do kit GESAI como uma alternativa de baixo custo para a avaliação de sistemas de irrigação.UEL2020-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3761510.5433/1679-0359.2020v41n5p1783Semina: Ciências Agrárias; Vol. 41 No. 5 (2020); 1783-1798Semina: Ciências Agrárias; v. 41 n. 5 (2020); 1783-17981679-03591676-546Xreponame:Semina.
