چکیده
in order to study the effect of planting pattern and nitrogen application on barley and faba bean yield and quality of forage in intercropping, an experiment was conducted on farm of agricultural and natural resources faculty of gonbad kavous university as factorial based on rcbd with three replications in 2012-2013. planting pattern consisted of five levels, i.e. sole barley, intercropping of barley with faba bean at 75:25, 50:50, 25:75 rations and sole faba bean and nitrogen fertilizer factor was comprised of four levels of 0, 25, 50 and 75 kg n ha-1. the results showed that effect of planting pattern on forage yield, height, percentage of dry matter digestibility, crude protein and acid detergent fiber at 1% probability level were significant. nitrogen fertilizer had additive effect on forage yield, height, percentage of dry matter digestibility and crude protein. sole barley produced the highest yield with13.38 ton ha-1 and sole faba bean produced the lowest forage yield with 7.4 ton ha-1. with increasing of faba bean in intercropping treatments, total yield decreased compared to sole barley. the highest and lowest crude protein percentage with 25.37 and 8.81 and dry matter digestibility with 69.96 and 58.96 percent was obtained from sole faba bean and sole barley, respectively. although forage yield in sole crop of barley was high but its quality was low.

Effect of nitrogen and cultivars on some of traits of barley (hordeum vulgare l.)
In order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at Isfahan in 2012. The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N kg/ha (urea)) and barley cultivars inclu...

متن کاملHow much is too much?—Influence of X-ray dose on root growth of faba bean (Vicia faba) and barley (Hordeum vulgare)
X-ray CT is a powerful technology to study root growth in soil in-situ. Root systems can be studied in its true 3D geometry over time. Hence, the same plant can be scanned multiple times during development. A downside is the potential of X-rays to interfere with biological processes and therefore plant growth. The aim of this study is to evaluate the influence of cumulative X-ray dose on Vicia ...
