Abstract
El maíz, un cultivo ampliamente consumido a nivel mundial, es una valiosa fuente de carbohidratos, proteínas y nutrientes esenciales. Esta investigación se centró en analizar el impacto de tres dosis de fertilizantes NPK en dos densidades de siembra de maíz (Zea mays L.) en Piura, Perú. El estudio se llevó a cabo con un diseño experimental de bloques completos al azar, combinando tres dosis de NPK y dos densidades de siembra, totalizando 24 parcelas. Se evaluaron el rendimiento, longitud, diámetro y peso de las mazorcas, así como el índice de cosecha. Los resultados destacan que la combinación de una densidad de siembra de 75 000 plantas por hectárea con la dosis D3 de fertilizante NPK (200-80-100) logró el mayor rendimiento de 16,399 kg/ha-1, evidenciando diferencias significativas en comparación con otras combinaciones. Estos hallazgos subrayan la relevancia de la densidad de siembra y las dosis de fertilizantes NPK en la productividad del maíz, resaltando la importancia de estos factores en la optimización de los rendimientos agrícolas.
Corn, a widely consumed crop globally, is a valuable source of carbohydrates, proteins, and essential nutrients. This research focused on analyzing the impact of three doses of NPK fertilizers at two planting densities of corn (Zea mays L.) in Piura, Peru. The study was conducted using a randomized complete block design, combining three NPK doses and two planting densities, totaling 24 experimentals units. The yield, length, diameter, and weight of the cobs, as well as the harvest index, were evaluated. The results highlight that the combination of a planting density of 75 000 plants per hectare with the D3 dose of NPK fertilizer (200-80-100) achieved the highest yield of 16,399 kg/ha-1, showing significant differences compared to other combinations. These findings underscore the importance of planting density and NPK fertilizer doses in corn productivity, emphasizing the significance of these factors in optimizing agricultural yields.
