Evaluación de la eficiencia del método de riego por goteo

Abstract

The research entitled "EVALUATION OF THE EFFICIENCY OF THE METHOD OF IRRIGATION BY DRIPPING", through the statistical, agronomic and economic analysis of three drip tapes (Lin, Streamline and Hydrodrip) with two distances between laterals (1.00 m and 0.80 m ), was carried out in the agroecological zone with sandy-loam soils of the Pilligloma Sector, Ignacio Flores Parish, Latacunga Canton, Cotopaxi Province. Its geographic coordinates are 00 ° 54' of South latitude and 78 ° 36' of West longitude, to an altitude of 2785 meters on the level of the sea. The block design was applied completely randomly, with a factorial arrangement of A x B (3 x 2) with 3 repetitions, and the Tukey significance tests were performed at 5% for the treatments that were significant, where the following were obtained. Results such as: for the variable Area under irrigation, the best treatment A1B2 (Hydrodrip tape with a distance between sides of 1.00 m) with 0.0255 m2, meanwhile for the variable Coefficient of uniformity of the drip, the treatment A1B2 was obtained (Hydrodrip tape with a distance between sides of 1.00 m) that prevails with 92%, likewise for the Coefficient of uniformity of distribution, the A1B1 treatment (Hydrodrip tape with a distance between sides of 0.80 m), with 88.66%, predominates. According to the respective statistical analysis for the variable Coefficient of uniformity of the emission of water per dropper, no significantly different results were recorded, for the variable Deviation medium, flow rate the best treatment is the A1B2 (irrigation tape Hydrodrip x distance between sides 1 m) with 76.12% given that the variation of the operating flow rate with the nominal flow rate given by its manufacturer is lower than the other treatments.
