Common Vetch ( Vicia sativa L.) Germplasm: Correlations of Crude Protein and Mineral Content to Seed Traits

In order to increase knowledge of seed nutritive value and to demonstrate its relationship in common vetch (Vicia sativa L.) germplasm, 388 common vetch accessions were grown under field conditions in 2008–2009 growing season in Bursa province of Turkey. Seeds were analyzed for seed minerals (Ca, Cu, Mg, Mn, P, S, Zn and K) and crude protein (CP) content. The accessions were grouped according to testa and cotyledon color and seed size, and the results were evaluated by analysis of variance to determine relationships between minerals and CP content, testa and cotyledon colors, and seed weight. In general, there was no significant difference between testa colors or cotyledon colors in minerals and CP content. However, seed weight was closely associated with minerals and CP contents in this study. Analysis of variance and correlation analysis showed that seed weight was closely associated with some minerals and CP content. The small seeds had significantly higher Ca, Cu, Mg, Mn, S, Zn and CP contents than medium and large seeds.

EFFECTS OF DIFFERENT SEEDING RATES ON FORAGE YIELD AND QUALITY COMPONENTS OF PEA CULTIVARS UNDER BURSA CONDITIONS

The aim of this study was to investigate the effects of seeding rate on yield and quality components in forage pea cultivars. Four pea cultivars (Ulubatli, Kirazli, Golyazi and Urunlu) and five seeding rates (75, 100, 125, 150 and 175 viable seeds m) were used in this study. Field experiments were carried out from 2009 to 2011 during the winter growth period at Uludag University, Faculty of Agriculture, Agricultural Research and Application Center in Bursa, Turkey. The experimental design was a randomized complete block desing with three replications. Dry matter yield, crude protein ratio and yield, acid detergent fiber, neutral detergent fiber, total digestible nutrients and relative feed values were determined. Significant differences were found among the pea cultivars and seeding rates in all measured characteristics in both years. The highest dry matter yield was obtained from the Kirazli cultivar at 125 seed m. The digestibility of the Golyazi cultivar was higher than the other cultivars. On the other hand, the digestibility of the forage decreased as the seeding rate increased.The aim of this study was to investigate the effects of seeding rate on yield and quality components in forage pea cultivars.
