SUPRESSÃO DE PLANTAS ESPONTÂNEAS POR ADUBOS VERDES EM ÁREA DE CULTIVO ORGÂNICO

Abstract

Este trabalho teve como objetivo avaliar o efeito de três adubos verdes na supressão de plantas espontâneas em uma área de cultivo orgânico. O experimento foi realizado em uma propriedade particular localizada no município de Rorainópolis-Roraima, o delineamento experimental em blocos ao acaso, utilizando espécies de crotalária (Crotalaria spectabilis e Crotalaria ochroleuca), feijão guandu (Cajanus cajan) e uma testemunha sem leguminosa, com quatro repetições. Foi usado como variável: massa seca e fresca e a densidade de plantas espontâneas aos 36 e 60 dias após a semeadura das leguminosas (DAS). A massa seca e fresca das plantas espontâneas foi inferior a testemunha nos dois períodos avaliados, com destaque para Crotalaria spectabilis e Crotalaria ochroleuca, que obtiveram melhores resultados na redução de biomassa das plantas espontâneas. Quanto a redução da densidade de plantas espontâneas, Crotalaria spectabilis apresentou melhor eficiência, comparada aos outros tratamentos. Assim, para este experimento, é recomendado o uso de adubos verdes, para um controle eficiente de plantas espontâneas.
