EVALUATION OF FORAGE YIELD AND LAND EQUIVALENT RATIO IN INTERCROPPING VETCH VICIA ERVILIA WITH AUTUMN BARLEY UNDER DRY LAND CONDITIONS OF ARDABILHossein MostafaeiAbstract This study aimed to compare dry matter yield determining the LER in monoculture and mixed native vetch (V. ervilia) with barley under rain-fed conditions were performed. Experiment based on a randomized complete block design (RCBD) with eight treatments and three replications were carried out. Treatments based on the weight ratios of intercropping vetch seeds - barley (in two ways topsy-row) and pure cultures of each of them at ratios of 25, 50 and 75 percent came from both plant. Analysis of variance showed a significant difference between experimental treatments in terms of dry weight. Mean comparison was conducted by using Tukey test showed that the highest amount of forage dry weight, the highest value (13.58 ha) owned 50 percent of vetch + 50% barley is mixed for cultivation, while in pure culture vetch, the lowest dry weight (7.16 ha) was produced. In this experiment, LER for all tangled and mixed cultures such as hairy vetch row except for the treatment of 75% vetch and 25% barely was higher than one. It was found that the highest land equivalent ratio of 1.48 that belongs to mixed cropping with 50% hairy vetch + 50% barley and the lowest was 8.0 LER of intercropping 75% vetch + 25 barley the row was obtained.
