Ítem Acceso Abierto Adaptabilidad del hibrido de maíz P4021 con tres densidades de siembra en el cantón Oña, provincia del Azuay(Universidad Católica de Cuenca., 2024) Ullauri Sandoval, Marco Esteban; Vázquez Vázquez, Jacinto Enrique; 010455117Corn stands out as the sole cereal suitable for human and animal consumption. Climate change-related alterations suggest the search for alternative animal feed. This research aimed to assess the effects of planting density on the agronomic performance of the P4021 corn hybrid in the Oña canton, Azuay province. A Randomized Complete Block Design (RCBD) was used, consisting of four treatments and four replicates, with a total of 16 experimental units of 12 m2 each across a 448 m2 area. Four planting densities —20, 40, 60, and 80 cm between plants, all at 60 cm between furrows— were tested, with two seeds dibbled per hole. The results revealed that planting density significantly impacts the agronomic performance of P4021 corn. Although no significant differences were observed on variables like height and leaf count, there were statistical differences in the variable weight per treatment (kg), highlighting the T1 treatment (40 cm between plants) with a mean of 27.6 kg. The cost analysis considers the T1 treatment as the optimal choice for planting this hybrid, compared to the control treatment (T4). In conclusion, planting density affects Hybrid P4021 cultivation, with 40 cm between plants yielding the best results in terms of profitability in the cost of production analysis, resulting in a 170% increase, making the T1 treatment ideal for corn silage.
