The quality and allelopathy properties of dwarf mucuna, dwarf pigeon pea and stylosanthes as cover crops on corn and weed species were evaluated.
La calidad de la mucuna enana, habichuela y estilosantes, como cobertura vegetal sobre maiz y especies invasoras fue evaluada.
A qualidade da mucuna ana, feijao guandu anao e estilosantes, como cobertura vegetal sobre milho e especies invasoras foi avaliada.
The aim of the present work was to evaluate the quality and the allelopathic potential of dwarf mucuna, pigeon pea and stylosanthes vegetal mulch on corn culture and weed species.
The leguminous species dwarf mucuna (Mucuna deeringiana (Bort.) Merr), pigeon pea (Cajanus cajan L.) and stylosanthes (Stylosanthes capitata and S.
The aqueous extract was prepared with fresh leaves of dwarf mucuna, pigeon pea and stylosanthes collected in the field, at blossom stage for the first two species and at vegetative stage for the third, since this last species entered the blossom stage at a different period.
In the evaluation performed 30 days after sowing of the leguminous plants dwarf mucuna, pigeon pea and stylosanthes there was no statistical differences among the treatments.
Dwarf mucuna, on the other hand, led to the lowest reduction (20%) at 30 days after sowing and the highest reduction (55%) at 60 days.
(1999) studied the phytomass of green manure and the control of weed plants as a response to population densities of leguminous species, and the largest inhibitions occurred in the plots of Mucuna aterrima and Canavalia ensiformis.
