Research on determination of proper seed mixture ratio of hungarian vetch and barley to be grown under conditions of Karaman

This research was conducted to determine the most proper seed mixture ratio of Hungarian vetch (Vica pannonica Crantz) and barley (Hordeum vulgare L.) to be grown under ecological conditions of province Karaman in the Dereköy Village, 7 km far from province Karaman during the growing season of 2008-2009. In the research, plant height, green and dried herbage yield, crude protein ratio and yield of pure sowings of Hungarian vetch and barley as well as their different seed mixtures such as 80% Hungarian vetch+20% barley , 60% Hungarian vetch+40% barley, 40% Hungarian vetch+60% barley, 20% Hungarian vetch+80% barley were studied. In addition to these, contribution ratios of Hungarian vetch to the green and dried herbage yields of the mixtures and relative yield totals of mixtures were determined. The experiment was arranged in a completely randomized block design with four replications.Results of the research showed that plant height, green and dried herbage yield, relative yield total values, ratios of Hungarian vetch in the green and dried herbage yield as well as ratio and yield of crude protein were statistically significant influenced by ratio of seed mixture. Increasing ratio of barley in the seed mixture increased green and dried herbage yield as well as crude protein yield while it decreased crude protein ratio. Ratios of Hungarian vetch in the green and dried herbage yield were lower than those in the seed mixture. The highest value of relative yield total was obtained from the seed mixture of 40% Hungarian vetch+60% barley. From the results of the study, it was concluded that the most proper seed mixture of Hungarian vetch and barley in hay yield and quality as well as in most effective using the ecological resources under conditions of province Karaman was the seed mixture of 40% Hungarian vetch+60% barley, but further research on the determination of most proper sowing time of the mixture is needed to obtain more balanced mixture of Hungarian vetch and barley.
