Abstract

The objective of this work was to evaluate the biomass production and the effect of the suppression ability of cover plants on the development of spontaneous plants in the region of the Coastal Plain of Piauí state, Brazil. The experiment was designed in a Yellow distrofic Latosol, with five treatments, and three species of leguminous plants − sunn hemp (Crotalaria juncea), jack bean (Canavalia ensiformis), and pigeon pea (Cajanus Cajan) −, besides the consortium of these species, and the witness (solo prepared and left in fallow land with spontaneous plants). The treatments that produced higher values of shoot fresh weight were the “consórcio” (the broadcast sowing of sunn hemp, pigeon pea, and jack bean); sunn hemp; and pigeon pea. The treatments that produced higher values of shoot dry mass were the “consórcio”, sunn hemp, and jack bean. The lowest production of fresh and dry root weight was obtained by pigeon pea. The fresh and dry weights of shoots and roots of spontaneous vegetation were superior in the control treatment. The cover plants used in the present work can be recommended for the suppression of spontaneous plants, as they can effectively reduce the fresh weight of spontaneous vegetation up to 93%, with the use of the “consórcio”.
