Some medicinal plants have an important role in production of fodder with high quality. While reducing the production costs, they protect the environment, water, and soil resources. On the other hand, mixed cultivation and application of organic and biological fertilizers or proper combination of these two with chemical fertilizers can be considered a solution to increase crop yield in sustainable agriculture. For this purpose, in order to investigate the effects of different treatments of fertilizer and ratios of mixed cultivation of Chicory and annual Medic, a factorial experiment has been conducted in a randomized complete block design with three replications at the experimental field located in Behbahan city in 2019-2020 growing season. The first factor has been different fertilizer sources (Chemical, Organic, and Integrated) in three levels: chemical fertilizer, vermicompost fertilizer and combined fertilizer (nitroxin biofertilizer + fertile phosphate 2 + 50% chemical fertilizer) and the second factor has been five intercropping patterns including: sole chicory (SC), sole annual medic (SM), one row of chicory: one row of annual medic (C1M1), one row of chicory: two rows of annual medic (C1M2) and two rows of chicory: one row of annual medic (C2M1). The studied traits are forage yield of chicory and annual medic and quality characteristics of forage including percentage and yield of crude protein, percentage of ash, crude fiber, dry matter digestibility, calcium, and phosphorus content of forage. The results show that the highest dry forage yields of chicory and medic (4.04 and 4.63 t/ ha, respectively) are obtained in monoculture and chemical fertilizer treatment. Mixed cultivation ratios and application of combined fertilizers and vermicompost improve crude protein and ash of medic and crude fiber of chicory forage without reducing any other quality traits. Evaluation of land equivalent ratio show the superiority of all mixed ratios over monoculture of these plants. Finally, mixed cultivation treatments C1M1 and C2M1 with a land equivalent ratio of 1.3 and a total yield of 5.44 and 4.95 tons per hectare and the application of combined fertilizer are recognized as superior treatments.

To evaluate the effect of arbuscular mycorrhizal fungi under water deficit stress on linseed, a field experiment was conducted as split-plot in RCBD design with three replications at the research station of faculty of Agriculture at Shahrekord University in 2013. Water deficit stress at four levels of no stress, mild, medium and severe stress as main factor and inoculation with Glomus intraradices, Glomus mosseae and no inoculation as sub factor were used. The results showed that the effect of mycorrhiza inoculation and water deficit stress treatment were significant on all the measured traits. Interaction between mycorrhiza and water deficit stress was significant on the plant height and shoot dry weight. Based on the results, both species of Glomus intraradices and Glomus mosseae significantly increased the grain yield whereas the treatment inoculated with G. intraradces produced maximum (0.080 kg/m2) and the treatment without inculation with mycorrhiza produced minimum (0.063 kg/m2) grain yield. Maximum (0.097 kg/m2) and minimum (0.050 kg/m2) grain yield were obtained in the treatment under water deficit stress and no-stress conditions, respectively.
