Fuentes de nitrógeno en el crecimiento y producción de biomasa en maíz

Abstract: El objetivo de esta investigación fue determinar la dinámica de crecimiento y la eficiencia de producción y distribución de biomasa en un híbrido de maíz forrajero (HT9019Y) fertilizado con dos fuentes de nitrógeno (tradicional y de lenta liberación), a partir de muestreos vegetativos y reproductivos efectuados en diferentes etapas fenológicas. La siembra se realizó en el ciclo primavera-verano 2014. Las fuentes de nitrógeno se distribuyeron en un diseño experimental de bloques… Show more

“…However, a progressive decrease was observed, reaching 50 cm 2 g -1 . LAR tends to be high at the beginning of a crop´s growth and decreases as developmental stages advance (Orozco-Vidal et al, 2016). This is because plants allocate most of the photoassimilates to the development of their photosynthetic apparatus; and as the crop progresses, the plant deposits carbohydrates in its reproductive organs.…”
