In order to evaluate the effect of planting bed on sole and mix cropping of barley and vetch on quantity and quality of hay, a factorial experiment based on randomized complete block design with three replications was conducted at paddy field of Rice Research Institute of Iran (Rasht) in 2014-2015. Experimental treatment were planting bed (with rice bran and without rice bran) and mixing ratio (100%Vetch, 100% Barley, 20% vetch additive to barley, 40% additive vetch to barley, 60% additive vetch to barley and 25% vetch and 75% barley as substitutive ratio of mix cropping). Results showed that using of rice bran as planting bed because of increasingly effect on planting density per square meter, increased hay, forage and protein yield. Between of mixing ratio treatment the highest of hay yield (39000 and 38167 Kg ha-1) and forage yield (11428 and 11294 Kg ha-1) was from 40 and 60% additive vetch to barley. That two additive treatment ratios had the advantage of substitutive ratio by hay (in order 11.96 and 9.57 percent) and forage (in order 11.85 and 10.54 percent). Land Equivalent Ratio (LER) of hay (2.02 and 1.97), forage (1.69 and 1.67) and protein (1.55 and 1.58) observed from 40 and 60% additive vetch to barley. Between of mixing ratio treatment, the highest of protein content obtained from sole cropping of vetch. In general, using of rice bran as planting bed and 40% additive vetch to 100% barley may increase because of the highest amount of hay yield, forage yield and protein yield of forage is recommended for Rasht rainfed conditions.
