Efecto de labranza y mejoradores de suelo en humedad y desarrollo radicular

Abstract

Se evaluó el efecto de tres sistemas de labranza: convencional (LC), vertical (LV) y cero (NL); y mejoradores orgánicos (algaenzimas, composta y micorrizas) en un suelo francoarcilloso para determinar retención de humedad, desarrollo radicular y rendimiento de avena forrajera (avena sativa). El experimento se estableció bajo un arreglo experimental, bloques al azar con arreglo factorial A-B y tres repeticiones. La humedad del suelo se determinó utilizando una sonda TDR FIELDSCOUT 300 en estratos de 7.6 y 12 centímetros. Durante la extensión del tallo y el espigamiento se midió el desarrollo radicular y rendimiento por mejorador y sistema de labranza basado en materia seca. Con los niveles de labranza se obtuvo diferencia significativa en la retención de humedad, con un valor de 21.32% en el ANOVA, donde NL es la que retiene mayor humedad. En el desarrollo radicular, LC muestra significancia, con un valor de 0.04 m3, y obtiene el mayor rendimiento de 5.16 t ha-1; LV y NL no muestran diferencia para exploración de raíces y rendimiento. Los mejoradores no inciden en la retención de humedad y desarrollo de raíces, tienen efecto positivo para rendimiento; los sistemas de labranza impactan en la retención de humedad y permiten el desarrollo radicular.
