| To investigate the yield and quality of forage in mixed intercropped of barley and fennel, an experiment was conducted as split plot using randomized complete blocks design with three replications at research farm of Agriculture and Natural Resources University of Ramin, Iran, in 2012-2013. In this experiment four nitrogen levels including 0, 70, 140 and 210 kg N. ha-1 were assigned to main plots and five levels of replacement ratios of mixed intercropped (100% barley), (75% barley + 25% fennel), (50% barley + 50% fennel), (25% barley + 75% fennel), (100% fennel) were randomized in sub-plots. Results showed that the highest dry forage yield (8271 kg.ha-1) and protein yield were obtained from 50% barley + 50% fennel and application of 210 kg N. ha-1. The highest crude protein content and dry matter digestibility were obtained from 100% fennel and application of 210 kg N. ha-1. The highest crude fiber was obtained from 100% barley and application of 70 kg N. ha-1, and the highest cell wall observed in 100% barley and application of 210 kg N. ha-1. The highest cell wall without hemicellulose was observed in 50% barley + 50% fennel and application of 140 kg N. ha-1. However, the highest ash content obtained from no application of nitrogen and 100% fennel. The highest soluble sugars content obtained from 75% barley + 25% fennel and no application of nitrogen. The highest essential oil content and yield was obtained from application of 210 kg N. ha-1 and 100% fennel. According to the results, 50% barley + 50% Fennel in 210 kgN. ha-1 produced the maximum dry forage yield and quality, so was considered superior treatment. |
