    Evaluación del producto avail en la absorción del fósforo en la producción de papa (Solanum Tuberosum), en el cantón Latacunga, parroquia Mulaló
    (2023-03) Pérez López, Kleber Sebastián; Pérez Salinas, Marco Oswaldo
    In Ecuador, the production of potato (Solanum tuberosum) is very important because it is an essential product in the daily diet of the inhabitants, especially in the interAndean region, this crop represents a very important source of income for the rural area and is also considered a fundamental pillar in the national economy, so it is important to carry out research to increase the yield of the crop. Phosphorus is the most important element in the mineral nutrition of the potato crop and the one that most limits yield. For this reason, the objective of this research was to evaluate the effectiveness of the product AVAIL on phosphorus absorption in potato crops. Different fertilization levels (180, 240 and 300 Kg/Ha) were used with and without AVAIL and with two different phosphorus sources, P2O5 and Mesz. Different parameters were evaluated (plant height, number of tubers per plant, percentage of first, second and third tubers, yield per plant and yield per hectare). The treatments that obtained the best results were F1 N3 P2 (T6) and F2 N3 P2 (T12) in all the variables evaluated, in which 300 kg of fertilizer + Avail were applied; thus, obtaining a class A rank. While treatments F1 N1 P1 (T1) and F2 N1 P1 (T7) presented lower yields in most of the variables evaluated, in which 180 kg of fertilizer without Avail was applied; obtaining class E, F and G ranges.
