The role of intercropping on yield potential of common vetch (Vicia sativa L.)/oat (Avena sativa L.) cultivated in pure stand and mixtures
2007
The present experiment was conducted under the ecological conditions of Tekirdag, Turkey during 1999-2001. Three levels of different mixtures vetch (Vicia sativa L.) and oat (Avena sativa L.) (25% vetch + 75% oat, 50% vetch + 50% oat, 75% vetch + 25% oat) and pure common vetch (100% vetch + 0% oat), pure oat (0% vetch + 100% oat) were used as experimental treatments. The objective of this research study was to determine the effects of different mixtures ratio on yield and yield components of common vetch (Vicia sativa L.) + oat (Avena sativa L.). Seeds were broadcasted at a rate of 180kg ha-1 for the grasses and 120kg ha-1 for the vetch. Field trials were arranged in a randomised complete block design with three replications. Plant height, number of branch per plant, number of pods per plant, herbage yield and dry matter yield were recorded. The two years' results showed that the highest and dry herbage yields were obtained from 25% vetch (Vicia sativa L.) + 75% oat (Avena sativa L.). As a result, the best mixture was 25% vetch (Vicia sativa L.) + 75% oat (Avena sativa L.). By this mixture, 25.3 t/ha herbage yield and 6.5 t/ha dry matter yields were taken.
