Producción de materia seca y calidad forrajera de leguminosas anuales de clima mediterráneo

Abstract

The aim of this study was to evaluate the forage yield and quality of local varieties of Bard vetch (Vicia monanthos), Grass pea (Lathyrus sativus), Field pea (Pisum sativum), Common vetch (Vicia sativa), Narbon vetch (Vicia narbonensis) and Bitter vetch (Vicia ervilia). The trial was carried out in three locations over three consecutive years of harvest. Quantitative (kg DM/ha) and qualitative variables (dry mater (%DM), crude protein (%PB), acid detergent fi ber (%FAD), neutral detergent fi ber (%FND) and metabolizable energy (Mcal) were determined for April, June and July. Highest yield in the April sampling was Bitter vetch (1.127 kg DM/ ha, 20,98 %PB and 2,327 Mcal/kg DM), followed by Common vetch (924 kg DM/ha, 23,01 %PB 2,498 Mcal/ kg DM). In the June, the highest yield species were Common vetch (1.895 kg DM/ha, 20,01 %PB and 2,247 Mcal/kg DM) and Bitter vetch (1.802 kg DM/ha, 16,12 %PB and 2,033 Mcal/kg DM). For July, the highest yield was for Bitter vetch (2.880 kg DM/ha, 13,98 %PB and 1.906 Mcal/kg DM), followed by Common vetch (2,777 kg DM/ha, 14.97 %PB and 2,043 Mcal/kg DM). Our results sown that, under the conditions of our study, Common vetch and Bitter vetch were the spices of greater interest as fodder for ruminants from the end of the vegetative period to the crop attained full ripeness.
