بررسی درصد دیواره سلولی، دیواره سلولی عاری از همی سلولز و خاکستر علوفه در کشت مخلوط جو و رازیانه در سطوح مختلف کود نیتروژن

In order to investigate of forage quality in intercropping of barley and fennel, an experiment was done as split plot based on a randomized complete block design with three replications at the research farm of Agriculture and Natural Resources of Ramin University during growing season of 2012-2013. Nitrogen levels in four levels (0, 70, 140 and 210 kg N. ha-1) in main plots and and the ratios of intercropping in five levels (pure culture barley and fennel), (75% barley + 25% fennel), (50% barley + 50% fennel), (25% barley + 75% fennel), were replaced in the sub-plots. The studied traits were included neutral detergent fiber, acid detergent fiber and ash. Results showed that the highest amount of the neutral detergent fiber of treated 100% barley with nitrogen level of 210 kg ha-1, the highest amount of acid detergent fiber from treated, 50% barley + 50% Fennel with nitrogen level of 140 kg ha-1 and the highest amount ash percentage from treated with zero level of nitrogen and 100% Fennel were obtained.
