Organic manure can be used as an alternative for chemical fertilizers in sustainable agriculture. Hence, compared with sole cropping systems, intercropping is a promising approach for crop production due to the lesser reliance on chemical fertilizer. In order to evaluate the effects of intercropping on yield and essential oil of dill (Anethum graveolens L.) under organic manure and chemical fertilizers, a factorial experiment was conducted in a randomized complete block design with three replications at Shahrekord University research farm in 2016. Sole cropping of soybean (S) and dill (D) accompanied by three intercropping ratios of them (S:D 2:1, S:D 1:1, and S:D 1:2) were evaluated as the first factor, and two sources of fertilizer (chemical fertilizer, and broiler litter) as the second factor. The results showed that the highest dry matter yield of dill (1001.48 kg ha-1) and essential oil yield of dill (18.47 kg ha-1) was observed in the one-row dill + two-row soybean. The maximum essential oil percentage of dill (2.64%) was achieved in sole crop under organic manure. The highest pod/ plant (47.50) and seed yield of soybean (2192 kg ha-1) were dedicated to the two-row dill+one-row soybean under organic manure. The maximum land equivalent ratio (1.19) was achieved in treatment of one-row dill + two-row soybean under organic manure. According to the results, treatment of one-row dill + two-row soybean under organic manure had the highest land equivalent ratio, and produced a large amount of dill essential oil; therefore, it was considered as the superior treatment.

In order to investigate the response of yield and yield components of two medicinal plants i.e, fenugreek (Trigonella foenum-graecum L.) and buckwheat (Fagopyrum esculentum Moench) to chemical fertilizer and organic manure, a factorial experiment was conducted in two sequential years in a randomized complete blocks design at the research farm, College of Agriculture, Shahrekord University, in 2014 and 2015. The factors consisted of two species of medicinal plants (fenugreek (legume) and buckwheat (non-legume)) and three different sources of fertilizer (chemical fertilizer, chemical fertilizer+ organic manure and organic manure). The results indicated that application of organic manure compared to chemical fertilizer in buckwheat significantly increased plant height (17.76%) and branches/plant (8%) in 2014, seeds/spike(28 and 19.53% in 2014 and 2015, respectively), seed yield (40.24 and 26.57% in 2014 and 2015, respectively), and biological yield (34.66 and 47.74% in the 2014 and 2015, respectively). Aapplication of organic manure compared to chemical fertilizer increased branches/plant (8%) and biological yield (25%) of fenugreek in 2014. Additionally, combination of organic manure with chemical fertilizer (50:50) compared to chemical fertilizer in the buckwheat significantly increased plant height (10.35%, in the 2015), seed yield (52.21 and 17.19% in 2014 and 2015, respectively), biological yield (24.86 and 26.35% in 2014 and 2015, respectively) and harvest index (21.53%, in 2014). Integrated fertilizer compared to chemical fertilizer increased branches plant -1 (16.70%, in 2014) and seed yield (14.40%, in 2015) in fenugreek. Finally, organic fertilizer and chemical fertilizer+ organic manure could be a suitable alternative for chemical fertilizer in cultivation of medicinal plant buckwheat (non-legume), but replacement of organic fertilizer in production of fenugreek may increase biological yield compared to chemical fertilizer.
