ABSTRACT
Stems, leaves, straw and silks of the plants used for production of baby corn can be used for animal feed, because they are rich in nutrients, especially protein. Two experiments were carried out in the period from December 2006 to September 2007, at the Experimental Station CCTA/UENF, in Campos/RJ/Brazil. The experiment was performed in two stages, the first consisting of the pre-cultivation of cover crops and the second was baby corn cultivation using seeds UENF 506-8 under no-tillage system. Cover crops treatments consisted of the following species: sorghum, crotalaria, jack bean (Canavalia) and their combinations, compared to the control. The objectives of this study was to evaluate productivity of biomass, crude protein and protein per hectare. The experiment presented on average 17 t ha-1 dry matter, 6% crude protein and 1.072 kg of protein per hectare. The highest fresh weigth occurred in experiment 2, where the cover treatment jack bean ovecame the combination jack bean + crotalaria and the expontaneuos vegetation.
