Evaluation of the Quality of Irrigation Machinery by Monitoring Changes in the Coefficients of Uniformity and Non-Uniformity of Irrigation

Recently, the development of agricultural technology has been focused on achieving higher reliability and quality work. The aim presented paper was to examine possibilities evaluating work wide-area irrigation machinery by monitoring coefficients uniformity non-uniformity irrigation. object research pivot equipped with sprinklers a total length from 230 540 m. commonly applied parameter for wide-range irrigators is coefficient according Heermann Hein CUH. Work evaluations were also carried out through other parameters applicable in practice, such as calculated Christiansen CU, Wilcox Swailes Cws, our introduced parameters, ar (derived degree unevenness Oehler) γr Voight). Other determining Hart Reynolds CUhr, further Criddle CUcr subsequently Beale Howell CUbr. Next, Oehler a, variation Stefanelli Cv, Voigt γ Hofmeister Ef evaluated. Field tests performed during growing season cultivated crops (potatoes, corn sugar beet) village Trakovice (agricultural enterprise SLOV-MART, southwest Slovakia) district Piešťany (Agrobiop, joint stock company). During research, inlet operating (speed stage, pressure, dose), technical (number sprayers, length, number chassis) weather conditions (wind speed temperature) recorded. obtained results examined one-way ANOVA analysis depending observed or input verified Tukey Duncan needed. Irrigation values ranged 67.58% (Cws) 95.88% (CUbh) conditions. 8.58 (a, Ef) 32.42% (Cv). indicate statistically significant effect site interest thus impact particular field (p < 0.05). When application different uniformity, showed only first test = 0.03, p repeated measurements, increased due inspection all sprayers reduction influence wind.
