| Due to the importance of forage plants for livestock feed and low crop production, an experiment was conducted to evaluate the quantity and quality of Vicia narbonensis and Hordeum vulgar intercropping in rainfed conditions of Khorramabad under the influence of biofertilizer Aztobarvar-1 and superabsorbent in the form of rainfed at the research farm of Faculty of Agriculture of Lorestan University in 2017-2018 cropping year as a factorial based on a randomized complete blocks design with three replications. The first factor in 5 levels: 1- vetch monocropping (100 percent vetch) 2- barley monocropping (100 percent barley) 3- intercropping (vetch 25 percent: 75 percent barley) 4- intercropping (50 percent vetch: 50 percent barley) 5- intercropping (vetch 75 percent: 25 percent barley) by substitution method and the second factor in four levels 1-No use of Aztobarvar -1 and superabsorbent material (control) 2- Aztobarvar-1 (seed and foliar spraying) 3- Superabsorbent 4- Aztobarvar -1(seed and foliar spraying) + superabsorbent was considered. The results showed that the highest total dry forage yield and land equivalent ratio were obtained from the treatment (50 percent vetch: 50 percent barley), the highest protein percentage and crude forage protein yield, as well as leaf area index were obtained from vetch and barley monocropping in which by increasing the proportion of vetch in the composition, an increase in protein occurred in barley forage. In vetch plant, increasing plant density decreased the anti-nutritional traits of forage (insoluble fibers in neutral detergents) and vice versa in barley, these traits increased. The results showed that the contribution of vetch in coexistence with barley was effective in production, on the other hand, the combination of biofertilizer Aztobarvar-1 as a reliable alternative to nitrogen fertilizers and superabsorbent with the ability to store rainwater, especially at the end of the growing season; in addition to increasing the quantitative and qualitative yield of forage ;could play an important role in sustainable agriculture and healthy production as the best solution in rainfed and low rainfall areas. |
