    Evaluación de la eficiencia de tres métodos de riego en el cultivo de mora (Rubus glaucus)
    (2025-02) Perez Abril Christopher David; Valle Velastegui Edgar Luciano
    The influence of drip, micro-sprinkler, and flood irrigation methods on the productivity and fruit quality of Castilla blackberry (Rubus glaucus) was evaluated under controlled conditions to determine their water efficiency and economic feasibility. A completely randomized block design was used with three treatments and two replications, analyzing variables such as uniformity and amount of water applied, installation costs, total fruit weight, number of fruits per plant, Brix degrees, polar and equatorial fruit diameters, plant height, and stem diameter. The results showed that micro-sprinkler irrigation exhibited the highest water efficiency, with a uniformity coefficient of 90.7%, achieving the highest total fruit weight of 90.09 g/plant and higher Brix values. Drip irrigation also showed favorable performance, with a uniformity coefficient of 95.5%, reaching a total fruit weight of 87.15 g/plant and providing an efficient alternative in water-limited scenarios. In contrast, flood irrigation had the lowest uniformity, with a coefficient of 56.7%, and the lowest total fruit weight of 87.40 g/plant, although its installation costs were significantly lower, with a total value of $171.25, compared to $281.25 and $258.25 for the drip and micro-sprinkler systems, respectively. These findings highlight the need to consider water efficiency and implementation costs when selecting an irrigation method, as an appropriate choice can optimize water resource use and improve the sustainability and productivity of Castilla blackberry cultivation, especially in agricultural conditions that require a balance between technical efficiency and economic viability.
