ABSTRACT
The experiment was conducted during two cropping seasons (2001/2002 and 2002/2003), with the objective to study the Phenology and agronomic performances of the fifteen ecotypes of the species (Vicia narbonensis L.) under the agro-climatic conditions of the semi-arid region of Setif. The various phenological stages of the plant, the fodder and grains yields and several characters relating to the quality of seeds were measured. The results obtained show large diversity among phenological ecotypes of Vicia narbonensis L. The ecotype 2466 is very early for the beginning of flowering, for full flowering, for the beginning of pods formation and for complete maturity. In contrast, ecotype 2390 is the latest for all the phonological stages measured. Concerning forage and grain production, the statistical analysis showed highly significant differences between ecotypes. The best fodder and grain productions are reported for the late flowering ecotypes. Ecotype 2390 produced average values of 2.5 ton dry matter ha-1 of fodder and 16.9 quintals ha-1 of grains. The fodder and grain yields were correlated positively (p
