Productive response of corn (Zea mays L.)under irrigation

Resumen

Objective: To evaluate the productive response of the maize variety H-Ame 15 in the soil and climatic conditions of the Horquita Agricultural Company.
Design/Methodology/Approach: an experimental investigation was carried out at the “La Prosperidad” farm during the cold and spring sowing seasons from January 2022 to June 2024. A simple randomized experimental design with five replications was conducted, and analysis of variance (ANOVA) simple classification was applied. The statistical software IBM SPSS© Statistics version 21.0 was utilized in all instances. Plots measuring 60 m2 were established for the evaluation of crop growth, development and yield
variables. The study area was characterized in its main components: soil, climate, crop and irrigation system. The irrigation regime was applied to reduce the number of irrigations in both seasons, taking advantage of rainfall and applying irrigation at the right time based on soil moisture monitoring. The morphoagronomic behaviors was evaluated and the crop yield was determined for each plot in both sowing seasons. The maize variety used was H-Ame 15, which was sown with a 0.90 x 0.25 m spacing. The area is serviced by the electric center pivot machine No. 2, Western model, with 5 towers, irrigating an area of 30.7 ha. For the study, 5 plots of 60 m2 (10 m long by 6 m wide) were established to evaluate growth, development, and yield variables of the crop, arranged in a completely randomized design. For each plot, 40 plants (8 per row) were taken as the
experimental unit.
Results: The study’s primary findings indicated that the soil, climate, and irrigation system characteristics of
the region are conducive to successful maize cultivation.
Findings/Conclusions: The morphoagronomic behavior exhibited by the maize variety H-Ame 15 demonstrated a high degree of adaptability to the soil and climatic conditions of the La Prosperidad farm,
with yields exceeding 9 t ha^-1 during the winter season.
