“…As hypothesized, by providing better conditions for the uptake of nutrients by companion plants treated with fertilizers, the DEO composition of Moldavian balm was improved (Amooaghaie & Golmohammadi, 2017). In line with previous studies, Vafadar‐Yengeje et al (2019) concluded that the Moldavian balm/faba bean intercropping under fertilizer application changed the DEO composition by enhancing the amount of geraniol and geranyl acetate in comparison with the sole cropping. According to these researchers, the path of synthesis of DEO depends on nutrients, especially nitrogen, phosphorus, and microelements.…”

“…Besides, the LER value >1 implies that the inter‐species competition is also less intense than the intra‐species competition. Similarly, previous studies showed that the use of environmental resources via both functional complementarity and facilitation in the intercropping system and yield improvements led to an increase in the LER (Fallah et al, 2018; Rezaei‐Chiyaneh, Amani Machiani, et al, 2020; Vafadar‐Yengeje et al, 2019).…”

The effects of an intercropping system combined with organic fertilizer application on the yield quality of medicinal plants and the involved mechanisms have not been well elucidated. To evaluate the effects of different fertilizers (vermicompost and chemical fertilizers) on the dragonhead essential oil (DEO) productivity (dragonhead = Dracocephalum moldavica L.) (D) in sole cropping and intercropping with common bean (Phaseolus vulgaris L.) (CB), a 3-year field experiment was carried out using a factorial based on randomized complete block design. We found that the highest common bean seed yield and dry matter productivity of dragonhead were obtained from sole cropping fertilized with vermicompost. Regarding the major DEO constituents, the highest content of geranyl acetate (42.2%), geranial (23.4%), and geraniol (17.81%) were recorded using the cropping ratio of 2D:1CB following the use of vermicompost.Soil micro-biochemical parameters (basic microbial respiration, substrate-induced respiration, microbial biomass carbon, alkaline and acid phosphatase, and urease) in the intercropping systems were found to be higher than those of the corresponding sole croppings. The highest soil microbial activity was observed in the intercropping ratios of 2D:1CB and 1D:2CB following the use of vermicompost. Furthermore, the highest land equivalent ratios (LER = 1.28) were achieved in the intercropping ratio 2D:1CB after vermicompost application. Thus, this combination of stimulated soil microbial activity and functionality, which in turn accelerated nutrient mobilization and availability, enhanced plant performance. Therefore, we can conclude that intercropping dragonhead with common bean at the ratio of 2D:1CB coupled with vermicompost application can be introduced as an alternative and sustainable strategy to reduce the use of chemical fertilizers.

“…Intercropping patterns, in which priority is given to the use of ecological and environmentally friendly methods, are of crucial importance for the improvement of the production of MAPs (Vafadar-Yengeje et al 2019;Rezaei Chiyaneh et al 2020). In developing countries, intercropping is known as a sustainable agricultural strategy that provides more than 15% of the world's food and feed supply (Liu et al 2017).…”

Only a few studies have hitherto investigated the effects of the application of organic fertilizers in intercropping systems on the plant essential oil (EO) productivity. Hence, this work has aimed to study the effect of different intercropping patterns on EO quality and quantity of sweet basil (Ocimum basilicum L.) under vermicompost application. In the present study, the cropping patterns consisted of 1B:1CB, 2B:2CB, 3B:2CB, and 4B:2CB (basil: common bean) as well as the pure culture of both crops and fertilizer treatments including usage or non-usage of vermicompost. The maximum seed yield of common bean (2786 kg ha −1) and dry matter yield of basil in the first (261.5 g m −2) and second harvests (214.7 g m −2) were recorded in the pure cultures fertilized with vermicompost. In addition, the nutrient uptake rate of macronutrients and micronutrients in both plants after application of vermicompost improved in intercropping patterns. In both harvests, the maximum EO content of basil (0.84% in the first harvest and 0.69% in the second harvest) was observed at the cropping ratio of 3B:2CB fertilized with vermicompost. Chemical analysis, achieved by GC-MS, evidenced 1,8-cineole, linalool, methyl chavicol, α-trans-bergamotene, methyl eugenol, and epi-α-cadinol as the main basil EO constituents in both harvests. The highest increment level for most ofEO constituents, nutrient uptake, and land equivalent ratio (1.52) were obtained in the intercropping pattern of 3B:2CB fertilized with vermicompost. In general, the intercropping pattern of 3B:2CB after use of vermicompost can improve the EO productivity and quality of basil. This intercropping pattern was accompanied by the increment of nutrient uptake. Therefore, this treatment can be introduced as a valid and sustainable strategy to replace chemical fertilizer and plant monoculture.

This study evaluates the effects of intercropping patterns, plant growth‐promoting rhizobacteria and arbuscular mycorrhizal fungi (AMF) on seed yield and yield components of black cumin (Nigella sativa L.) and fenugreek (Trigonella foenum‐graecum L.), as well as the essential oil and fatty acid profile of black cumin. A two‐year two‐factorial field experiment was conducted in 2015 and 2016 to investigate intercropping of black cumin and fenugreek in five ratios and biofertilizer application as AMF and bacteria. Intercropping reveals higher concentrations of nitrogen and phosphorus compared with monocropping, whereas monocropping inoculated with bacteria shows the highest seed yield of both fenugreek (151 g m−2) and black cumin (148 g m−2). Regarding the quality of black cumin, the combination of a black cumin:fenugreek‐intercropping pattern of 66:34 with bacteria fertilization is most promising, as it shows i) the maximum essential oil content, oil yield, and fixed oil content, ii) the highest contents of thymol and p‐cymene, iii) the highest content of linoleic acid, and iv) the maximum land equivalent ratio. Conclusively, bacteria fertilization and black cumin:fenugreek‐intercropping pattern of 66:34 helps improving essential oil, fixed oil quality, and quantity of black cumin, thus creating a more sustainable cultivation system for black cumin and fenugreek.
