Two species of mint Mentha piperitha (peppermint) and M. arvensis (Japanese mint) are widely cultivated in Iran, but their response to fertilizer regime has not been evaluated so far. A field experiment was conducted to investigate the effects of different organic and chemical fertilizer treatments [Control, 100% urea (95 kg N ha−1), 75% urea (71.25 kg N ha-1) + 25% vermicompost (3.3 t ha-1), 50% urea (47.5 kg N ha-1) + 50% vermicompost (6.75 t ha-1), 25% urea (23.75 kg N ha-1) + 75% vermicompost (10.1 t ha-1) and 100% vermicompost (13.5 ton ha-1)] on essential oil contents, yield and yield components of the two species of mint. Peppermint provided grater plant height, number of internodes, number of leaf and oil percentage compared with the Japanese mint under study. The results indicated that, irrespective of the mint species, plants treated with combined chemical and organic fertilizer presented taller plants, higher oil contents and oil yield compared with solo chemical or organic fertilizers. Oil percentage and essential oil yield of mint increased significantly under the treatment with 25% urea (23.75 kg N ha−1) + 75% vermicompost (10.1 t ha-1). Plant height and number of leaf increased along the replacement of organic fertilizer with chemical fertilizers. The results showed that there was a positive and significant correlation with leaf number and essential oil yield. Application of vermicompost in combination with chemical fertilizer increased plant height, oil percentage and essential oil in both species, suggesting that organic and chemical fertilizer combination improves performance and environmental sustainability.

This study was carried out to determine the effects of different combinations of chemical and organic fertilizers on yield and essential oil ratio in coriander plant. Research, 2019-2020 vegetation period situated in Turkey's semi-arid climate prevails that was conducted in Southeastern Anatolia Region Siirt conditions. A total of 11 subjects, different combinations of chemical and organic fertilizers, formed the subject of the study in the study, which was established with 3 repetitions according to the randomized blocks trial design. According to the results of the research, the effect of chemical and organic fertilizer combinations on plant height and essential oil ratio in coriander plant is statistically insignificant. The number of seeds in the main umbrella and biological yield at p<0.05 level, the number of umbellet in the main umbrella, harvest index, seed and essential oil yield at p<0.05 level were statistically significant. In the research, the highest number of umbellet and seeds in the main umbrella were vermicompost (100%), harvest index (50% NPK + 50% chicken manure), seed yield (50% NPK + 50% chicken manure and 75% NPK + 25% chicken manure) and essential oil yield (50% NPK + 50% chicken manure). According to the research subjects, the plant height is 64.37-75.90 cm, the number of umbellet is 5.40-6.27 in the main umbrella, the number of seeds in the main umbrella is 32.47-41.53, the biological yield is 411.83-687.90 kg/da, the seed yield is 101.05-186.91 kg/da, harvest index, 22.23-36.28%, essential oil rate 0.30-0.32%, essential oil yield varied between 0.30-0.60 L/da. It was concluded that chemical fertilizer and organic fertilizer applications in coriander cultivation in semi-arid climatic conditions increase yield and some yield criteria.

An experiment was conducted during 2015-2016 as a split factorial in a randomized complete block design (RCBD) with three replications. Experimental factors were nitrogen fertilizer at four levels 0, 50, 100 and 150 kg/ha as the main factor and two types of green manure. Alfalfa (Medicago sativa) and secale (Secale montanum) in two states (use and non-use) were considered as sub-factors. Medicago sativa and Secale montanum were cultivated as green manure in September 2015 and returned into the soil by ploughing at the fall of 2015. Thereafter, Mentha piperita was planted and the crop was taken care of in order to collect the samples. The highest increase of peppermint essential oil percentage and essential oil yield in different treatments resulted from the application of 150 kg/ha of pure nitrogen with 0.35% and 45.60 kg/ha, as well as the use of M. sativa with 0.43% and 55.80 kg/ha, the use of S. montanum with 0.44% and 49.50 kg/ha, respectively. The highest essential oil percentage and essential oil yield were recorded under the influence of the double interaction use of 150 kg/ha of pure nitrogen and use of green manure of M. sativa with average 0.62% and 80.30 kg/ha, respectively. The triple interaction of experimental factors on traits tested showed that nitrogen treatment of 150 kg/ha with M. sativa and S. montanum produced the highest percentage of essential oil and essential oil yield of average 0.73% and 91.65 kg/ha, respectively.

Abstract Intercropping is an important and sustainable cropping practice in agroecosystems. Intercropping is a planting technique that farmers and gardeners can use to promote beneficial plant interactions and increases in biodiversity, enhanced production and lower economic risk. In the search for sustainable agricultural methods for medicinal plants, fenugreek and dill plants were intercropped at different additive (1:20, 1:40 and 1:60) and replacement (1:1, 1:2 and 1:3) series, at the Research Farm of the Faculty of Agriculture, University of Tabriz, Iran. Field experiment was arranged as split plot based on randomized complete block design in three replicates. Dill umbels were harvested at flowering, pasty and complete ripening stages. Results showed that among harvesting times, pasty stage had maximum essential oil percentage, essential oil yield and harvest index of essential oil, whereas among intercropping patterns, 1:1 and 1:20 treatments had the maximum values. Fenugreek as a medicinal, forage and legume crop promote dill essential oil yield and harvest index and could be an effective plant in intercropping systems.

"The experiment was carried out in fields of Agricultural Research and Experiments Station (2) affiliated with the College of Agriculture / Al-Muthanna University during growth season 2018-2019 to study the effect of spraying three different concentrations of salicylic acid (0, 100 and 200 mg.L-1) and spray date it at three different dates (60 , 90 and 120 days after planting) on growth of Coriandrum sativum L. and a volatile oil content in seeds. The experiment was applied using a randomized complete block design RCBD with three replications. The results showed that plants treated with salicylic acid (200 mg.L-1) was significantly outperformed of dry weight shoot, the weight of 100 seeds and seed yield gave (21.76 g.plant-1, 1.22 g and 7.79 g.plant-1) respectively. While, the plants treated with salicylic (100 mg.L-1) was significantly outperformed and gave highest values of essential oil percentage (0.87%) and essential oil yield (6.32 μl.plant-1). The plants that were sprayed with salicylic after 120 days of cultivation outperformed significantly in the weight of 100 seeds, seed yield and essential oil yield were gave (1.12 gm., 7.54 gm.plant-1 and 5.53 μl.plant-1). While, the highest values were recorded in the dry weight of the shoot total (20.51 g.plant-1) and in essential oil percentage (0.787%) in plants that were sprayed after 90 days of cultivation."

Carbon dioxide enrichment and nutritional improvement can increase photosynthesis and growth of different crops. The aim of the present study was to assess interaction effects of CO2 enrichment and fertilizer on physiological characteristics and lemon balm essential oil. Experimental units were composed of CO2 at 380, 700, and 1050 ppm with and without manure and N fertilizer application. A continuous increasing trend of individual plant leaf area, total dry weight accumulation and relative growth ratio were recorded with CO2 enrichment. When CO2 was elevated from 380 to 1050 ppm, the values of height (24.3%), SPAD reading (2.7%), essential oil yield (26.3%) and final yield (65.3%) were increased, unlike, stomatal conductance (35.2%) and essential oil percentage (53%) were decreased. The highest and the lowest values (except for oil percentage) were obtained under N and no fertilizer application, respectively. Except for SPAD, interaction between CO2 enrichment and each fertilizer on all measured characteristics had a significant effect, so that CO2 effect was intensified by applying each fertilizer. Therefore, it can be concluded that when temperature increase caused by rising CO2 is not considered or there is not a limitation for resources, CO2 enrichment will improve lemon balm biomass and essential oil yield.
