El maíz (Zea mays L.) es uno de los principales cultivos agrícolas en Brasil, y la eficiencia de la fertilización fosfatada es decisiva para su rendimiento productivo. En suelos tropicales, la disponibilidad de fósforo y el modo de aplicación pueden interferir con la absorción de nutrientes, afectando el crecimiento y el rendimiento. Este estudio tuvo como objetivo evaluar diferentes formas de aplicación de fósforo en el desarrollo y la productividad del maíz en el campo experimental UNIVAG en Várzea Grande, Estado de Mato Grosso, Brasil. El experimento se llevó a cabo entre julio y noviembre de 2021, en un diseño de bloques completos al azar, con cinco réplicas y cuatro tratamientos: aplicación en surco simple, surco doble, voleo y control. En la siembra, se aplicaron 30 kg N ha⁻¹, 120 kg P ha⁻¹ y 60 kg K ha⁻¹; en la cobertura, se utilizaron 180 kg N ha⁻¹ y 90 kg K ha⁻¹. La siembra se realizó manualmente, con un espaciamiento de 0,45 m, y las parcelas se manejaron según las recomendaciones técnicas del cultivo. Se evaluaron la altura de la planta, el diámetro del tallo y el rendimiento de grano. Los datos se sometieron a un análisis de varianza y las medias se compararon mediante la prueba de Tukey al 5%. No se observaron efectos significativos de los métodos de aplicación de fósforo en el diámetro del tallo (media de 20,6 mm) ni en el rendimiento de grano (media de 9.051,7 kg ha-1). Por otro lado, se verificó un efecto significativo en la altura de la planta, con aplicaciones a doble surco (2,34 m) y al voleo (2,32 m) que mostraron valores superiores en comparación con las aplicaciones a un solo surco (2,20 m) y el control (2,12 m). Se concluyó que, en las condiciones evaluadas, las diferentes formas de aplicación de fósforo no alteraron el rendimiento de grano del maíz, pero sí influyeron en el crecimiento vegetativo, ya que las aplicaciones a doble surco y al voleo favorecieron una mayor altura de la planta sin traducirse en ganancias productivas.
