To compare dry forage yield and quality of hairy vetch and triticale in pure stand and mixed cropping, a field experiment was carried out in Zanjan Agricultural and Natural Resources Research Center, in 2007-2008 and 2008-2009 growing seasons. The experiment was layed out as randomized complete block with five treatments and four replications. Treatments were mixing ratio including, hairy vetch and triticale pure stand, mixtures of 75% hairy vetch+25%triticale, 50% hairy vetch+50% triticale, 25% hairy vetch+75% triticale. The seeding rate of hairy vetch and triticale were 90 ,125 kg.ha-1, respectively. Analysis of variance showed that there were significant difference between two growing seasons and cropping components. Dry forag yield, nitrogen, phosphorous, potassium and protein yield were significantly higher in second year. Mixed cropping of 50% hairy vetch+50% triticale showed higher performance than other treatments for dry yield, uptake of nitrogen, phosphorous, potassium and crude protein yield. This mixed cropping had 8850 kg.ha-1 dry forage and 1412.26 kg.ha-1. For all mixed cropping, land equivalent ratio (LER) was greater than 1, and 50% hairy vetch + 50% triticale treatment had the highest LER and LER for crude protein yield. LER for dry forage yield of the mixed cropping of 50% hairy vetch+50% triticale was 1.32, 1.35 and LER for crude protein yield was 1.54, 1.57, respectively. |
