Respuesta del cultivar de fresa a tres frecuencias de riego por goteo, bajo macrotúneles

For the cultivation of strawberries in the town of Urdaneta, no studies have yet been carried out in this agricultural sector, and so this research was one of the first to be conducted, whose main objective was to contribute to the efficient use of water using management irrigation frequencies under covered shelter in order to generate a sustainable technology in the production of strawberries, and so the results from this research were directly linked to the productive sector. This research paper called "RESPONSE TO GROWING STRAWBERRIES USING THREE FREQUENCIES IN A DRIP IRRIGATION SYSTEM BENEATH MACROTUNNELS", aimed to: Determine the most efficient irrigation frequency out of three in the cultivation of strawberries in order to recommend its application to local farmers. In addition, to determine the effect of irrigation frequencies on different phenological stages of cultivating the "Albion", strawberry variety and to recommend the best one. The research was conducted on the student's property which was located in the Baber Bajo sector within the Urdaneta parish in the Canton of Saraguro, within the province of Loja. For this thesis 1104 strawberry plants of the "Albion" variety were distributed amongst others at a distance of 0.30 m and rows of 0.40 m, according to the design study. Of the 1104 plants, 90 were monitored and 10 were subjected to each treatment and repetition. Treatment 1 underwent daily watering (T1Fr1); Treatment 2, underwent watering every three days (T2Fr3) and treatment 3 every six days (T3Fr6). The statistical model of randomized block design was used, with three treatments and three repetitions using drip irrigation. The area where the trial was conducted was homogeneous across all experimental units. It must be stressed that the data collection with respect to the dependent variables from the second objective was carried out at 53 and 99 days after planting and data collection from the first objective was carried out at 116 days, during which time most of the plants were showing fruit. From the statistical analysis (ANEVA), the following results emerged in connection to the variables: petiole length (cm), petiole width (mm), leaf width (cm) and leaf length (cm). In all three treatments there were significant differences at 1% and 5%, that is to say that treatment 1 and 2 were performed better than treatment 3. The treatment that yielded better strawberry production was where irrigation was applied every day (T1Fr1 ), with the following settings: treatment 1 Fr1 = 7.08 t / ha; Treatment 2, Fr3 = 6.43 t / ha; treatment 3 FR6 = 5.52 t / ha. In order to measure the daily evaporation, an artisanal evaporation pan as recommended by (Sivisaca, 2013) was used, which provided similar measurements to a standardized tank, the evaporation values obtained were 2mm to 4 mm / day; with average of 2.7 mm / day, in the same way the average values obtained for relative humidity was 57.7% and an average temperature of 24.4 ° C. The same values were obtained with a Hygrometer that recorded minimum and maximum temperatures as well as relative humidity. The total level of irrigation applied to the crop with an application efficiency of 90% was 129.03 mm which corresponded to a total of 116.13 mm of evapotranspiration. All the cultural practices of strawberry crop production were carried out such as: planting, fertilizing, sanitary pruning, phytosanitary control (pests and diseases), and all the three treatments were carried out under equal conditions (soil and fertilization). The disclosure of the research was carried out during a field trip, in which were present: students studying agronomy, the degree course coordinator for agricultural engineering, thesis director and farmers during a presentation whereby the methodology and results obtained in this investigation were disclosed.
