Title A name given to the resource Producción de maiz mediante la introducción de los abonos verdes en la agricultura cubana Creator An entity primarily responsible for making the resource Mayte Alvarez, Gloria M. Martín, Ramón Rivera Description An account of the resource RESUMEN Los abonos verdes son plantas que se cultivan para ser incorporadas al suelo y suministrar nutrientes y es por esto que constituyen una alternativa natural y económica frente a los fertilizantes minerales. Con el objetivo de conocer la influencia de los mismos en rotación en el cultivo del maíz, se llevó a cabo un experimento sobre un suelo Ferralítico Rojo en el cual se evaluó la potencialidad de cuatro leguminosas en el suministro de Nitrogeno necesario al cultivo del maíz. Los resultados mostraron evidentes efectos positivos de este tipo de plantas desarrolladas en primavera - verano, las que incorporan altos volúmenes de biomasa y nutrientes, lo que se refleja en un incremento de los rendimientos del maíz, encontrándose la influencia más marcada con la incorporación de Crotalaria juncea. En las condiciones estudiadas, los abonos verdes pueden ser una alternativa para la sustitución de fertilizantes químicos nitrogenados necesarios al cultivo del maíz (40-80 kg/ha de N) y permiten incrementar los rendimientos del cultivo (1-2.4 t.ha-1 ), así como obtener ganancias económicas de hasta $465.00/ha como promedio. Palabras clave: abonos verdes, maíz, rendimientos, nitrógeno ABSTRACT Green manures are plants which are harvested in order to be incorporated to the soil as nutrient supply. Therefore they constitute a natural and economic alternative to minerals. An experiment was carried out in ferralitic red soils in order to study the influence of green manures in rotating corn crops, assessing the potentiality of four (4) leguminosae in supplying N necessary for corn. The results showed evident positive effects of those plants developed in spring summer, which incorporated high biomass and nutrient volumes, being this reflected in an increase of corn yields, meeting the must markedly influence with the incorporation of Crotalaria juncea. Under the studied conditions, green manures can be an alternative for substitutions nitrogen chemical fertilizers necessary for corn crops (40-80 kg/ha de N), also allowing an increase in crop yield (1- 24 t/ha), as well as obtaining economic earnings of up to $465.00/ha as an average.
