Description
Common vetch (Vicia sativa L.) is widely used as a seed or hay crop in Turkey. In humid coastal areas it is principally used fot hay or green herbage while in dry regions it is used mostly for seed. Roughly ground vetch seed is a popular concentrated feed and mixed with straw or cereal grain (A9ikg6z, 1988). Approximately 200.000 ha of common vetch are seeded every year in Turkey. It is sown mostly as a spring-seeded crop and is often subjected to severe heat and drought stress as the season progress. Yields are generally low with an average seed yield of0.75 to 1.0 t ha-1 during the period of 1975-86. Whereas the fall-sown crop, if it can be grown, has several advantages, including the completion of critical flowering and pod-filling stages before soil moisture and air temperature become limiting. Previous studies have shown a clear yield increase in favour of fall sowing in the coastal areas (Cakmak9i and A9ikgi:iz, 1987). Fall-sown crops are potentially higher yielding but in regions with severe winters like the inner regions of Turkey winter killings occurs and vetch should only be seeded in the spring. The released common vetch cultivars are grown in all parts of the country. The strains which can be sown both in the fall and spring are preferred. Thus, the yield stability of common vetch strains under diverse environments and sowing time is very important feature. The relationships of yield components with the seed yield have been studied in several legume species. In early studies with faba bean (Vicia faba L.), seed size, seeds/pod and seeds/plant showed a high and significant correlation with yield (Lawes et al., 1983). Also in pulse crops, the pods/plant, seeds/pod and seed weight were found to be the most important yield components (Adams, 1967; Duarte and Adams, 1972; Cousin et al., 1985; Singh et al., 1985). Seitzer and Evans (1973) indicated that the characters 1000-seed weight and seeds/pod remain fairly constant in faba bean. Slim et al., (1985) found that seed yields were similar in both fall-sown and spring-sown pea (Pisum sativum) crops. The main aim of this study was to determine the effect of locations and sowing times on the seed yield, and their infuence on the yield components and stability of common vetch.

Variation of Seed Yield and its Components in Common Vetch (Vicia sativa L.) Under Different Conditions
