Valutazione bioagronomica e stabilità produttiva in genotipi di veccia comune (Vicia sativa L.).

Risultato della ricerca: Otherpeer review


The vetch (Vicia sativa L.) is an important crop for the hot-arid Mediterranean regions. The species it is used for fresh and dry fodder production and occupy an relevant position within the dry crop rotations. In Italy a significant amount of grain for livestock use is importing from European and non-Europeans Countries, despite the fact that the production of certified seeds is quite idespread in almost all areas of South-Central Italy. For this reason, this study has been undertaken to ascertain bio-agronomic and production behavior of common vetch varieties for forage and seed yield to provide useful guidance for farmers. The experimental trials were carried out during two growing seasons (2007/08 and 2008/09) in Cammarata (Agrigento, Italy.). A randomized complete block design with three replications was used to compare bio-agronomic response of 17 vetch genotypes some of whom already present in the Italian National Register of Varieties. In the present article we reported only the following results: biomass and yield (t ha-1), protein content of grain (%), height plant (cm) and 100 grain weight (g).Over the two seasons, vetch grain yield and qualitative grain traits were highly variable. In particular, the values of biomass ranges between 7.00 t ha-1 and 2.70 t ha-1 during the first year and between 2,87 t ha-1 and 4,53 t ha-1 in the second year.Marianna genotype showed higher yield in both field trials, while Caterina genotype and Senda 150 DE genotype showed the lowest yield (0,61 t ha-1 and 0,60 t ha-1 respectively in the first and second year. The average protein content in fist year was 31,6% while, in the second year was 26,6%. The highest value was recorded by Josè genotype in both field trialsThe results, obtained during this two experimental trials, have contributed to increase the knowledge of the available vetch germoplasm and to highlight the high variability of investigated bio agronomic and quality traits. Moreover, same traits have showed a high genotypes-year interaction due to different meteorological conditions for the two growing seasons. This effect should be studied in depth in order to select suitable vetch genotypes in hot-arid Mediterranean regions, typical of internal Sicilian areas.
