COVER CROPS IN THE OFF-SEASON IN THE WEED MANAGEMENT AT NOTILLAGE AREA

ABSTRACT Cover crops can provide suppression of weeds and together with chemical control make the proper management in agricultural areas. The objective this study was to evaluate effect cover crop cultivation during off-season on weed development a no-tillage area. experimental design randomized blocks scheme six treatments four replications. were: fallow (control), millet (Pennisetum glaucum) + crotalaria (Crotalaria spectabilis C. juncea ochroleuca), pigeon pea (Cajanus cajans), Urochloa ruziziensis, ruziziensis buckwheat (Fagopyrum esculentum. evaluations were done at 30, 75 225 days after sowing (DAS). main growth species area Cenchrus echinathus, Euphorbia heterophylla Digitaria insularis. Fallow treatment showed greater number density 184 plants m-2, 9.0 527.8 g m-2 dry matter mass DAS. In all verified reduction compared fallow, average 30 5.8 7.9 DAS, respectively. use is an important strategy for
