A study on the effect of growing site on the growth of the dill herb at three locations (Helsinki, Sahalahti, Inari) in Finland and at Freising, West Germany, was carried out in 1985. The growing medium was fertilized peat of the same quality at each location. Dill (’Dura’) was sown twice, in early spring and 2—3 weeks later at all growing sites. The herb crop was harvested just when the first flower buds had developed. The later sowings gave significantly larger yields than the earlier ones. The herb yields were largest at the most southern location. The fresh yield was the larger the more rain there was, and the warmer the growing season was. The significantly highest oil contents were recorded in the herb of the later sowings at Freising and Sahalahti. Otherwise, no differences in the oil content were recorded. The correlation between the oil content and degree days was positive. The total amount of components responsible for the aroma varied between 4.5 and 7.9 mg/g dry weight. The amount of essential oil and that of a typical aroma compound in dill, 3.6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran, were not significantly affected by the location.

Plants of rosemary [Rosmarinus officinalis L. (Lamiaceae)] were grown in pots containing a soilless (1 sphagnum peat:1 perlite) or soil-based (1 sphagnum peat: 1 perlite:1 field soil) growing medium and fertilized with either 12N-5.2P-12.5K controlled-release fertilizer (CRF) at 9.0 g/pot; constant liquid fertilization (LF) with 20N4.3P-16.7K at 150 mg N/liter; constant LF at 150 mg N/liter, plus CRF at 4.5 g/pot; weekly LF at 150 mg N/liter; or weekly LF at 150 mg N/liter, plus CRF at 4.5 g/pot. Constant LF plus CRF generally reduced plant height and depressed shoot fresh weight relative to other fertilizer regimes. Essential oil content was highest in plants receiving weekly LF. Plants grown in the soil-based mix were shorter, shoot fresh and dry weight tended to be lower, and essential oil yield was higher when compared to plants grown in the soilless mix. Satisfactory growth was obtained in both media when rosemary plants were fertilized with 12N-5.2P-12.5K CRF at 9.0 g/pot or weekly LF with 20N<.3P-16.7K at 150 mg N/liter.

Dracocephalum moldavica L. of the Labiatae family is an annual herbaceous plant. In Iran it is known as Badrashbi and Badrashboo. Recent publications have reported antibacterial and antimicrobial properties of its essential oil, which have a wide usage in industry. In this research, the effects of iron foliar application and different yields’ harvest times on the essential oil content and some morphological treats (plant height, branch number, fresh and dry weights, essential oil content and leaf Iron content) were investigated under experimental study in faculty of Agriculture of Urmia University during 2012. A factorial experiment in a randomized complete block design with three replications was used in the present study. Results showed that foliar application of iron had a significant effect on branch number, fresh and dry weight, biomass and oil percentage. Similarly, harvest time had a significant influence on fresh and dry weight, essential oil content, essential oil yield and leaf iron content, but its effect was not significant on stem diameter and branch number. The best harvest time for Dracocephalum moldavica L. was at 100% of flowering and 6 ml/l of iron application showed the best results in all characters measured.

Lamiaceae is one of the largest families of aromatic plants and it is characterized by the presence of external glandular structures which produce essential oils highly valued in cosmetics and medicine. Plants of Lavandula latifolia, Mentha piperita, Salvia sclarea, Salvia lavandulifolia, Thymus capitatus, and Thymus mastichina were grown for one year. In order to evaluate the effects of drought stress, plants were subjected to two water treatments (100% ETo and 70% ETo, including the rainfall during the experimental period). At the end of the experiment, the biomass, the essential oil content, and leaf nutrients concentration were assessed for each water treatment and species studied. At the end of the experiment, L. latifolia, M. piperita and T. capitatus plants showed a significant fresh weight reduction under drought stress conditions whereas the other species studied remained unchanged. With respect to dry weight, only L. latifolia plants showed a reduction under water deficit conditions. As far as essential oil content was concerned, L. latifolia and S. sclarea plants had a reduction under water deficit conditions. Leaf nutrient concentration showed different trends between species considering the nutrient assessed. The economic viability of the growth of this species will be dependent on the benefits achieved which are related to yield production obtained and the price accorded for both raw material and the essential oil extracted.

Second Year

In order to study the effects of biological and chemical fertilizers on quantitative and qualitative yields of purple coneflower, an experiment was carried out during 2010-2012. The morphological traits such as plant height, number of lateral shoots, shoot fresh and dry weight, root fresh and dry weight, number of inflorescences per plant, number of flower buds per plant, and essential oil content and yield were measured. The results showed significant effects of the treatments on the growth parameters. In the second year, the mixture of the three bacteria plus mycorrhizal inoculum improved important parameters such as shoot dry weight (40.42%), root dry weight (60.02%), and number of inflorescences per plant (65.68%). Interestingly, these values were not significantly different from obtained results by the chemical fertilizers. Additionally, the essential oil content in plants treated with the mixture of the three bacteria were 152.14% and 25.11% higher than the control plants in the first and the second year, respectively. The essential oil yield in plants treated with the mixture of the three bacteria was higher than those treated with the chemical fertilizers in two years. The results indicate that using biological fertilizers is a good choice to reduce the use of chemical fertilizers as an important tool to contribute to a sustainable agriculture.

To study the effect of plant density and different nutritional systems (chemical, biological, and integrated) on the quantitative and qualitative performance of Thymus daenensis L. in Mahidasht Agricultural Training Center, Kermanshah/Iran, in 2017, an experiment was conducted in a split-plot design based on a randomized complete block with four replications. The first variable involved two planting distances in the row of 15 and 30 cm (the main factor), and the subsidiary factor comprised four different nutritional systems including control (no-fertilizer), chemical (100 kg superphosphate, 100 kg potassium sulfate, 150 kg urea per ha), biological (8 tons of cattle manure/ha), and integrated (50% cattle manure + 50% chemical) fertilizers. The results showed that the integrated fertilizer treatment produced the highest shoot dry weight (789.1 kg/ha), essential oil content (3.35%) and root length (15.97 cm). The integrated fertilizer treatment along with the 30-cm planting density resulted in the highest essential oil content of 3.35%. The results of this project have suggested that the integrated fertilizer and the 30-cm planting interval is the optimal treatment in thymus production due to the higher chemical fertilizer efficiency and better crop quality.

Ripening Stages

With the view to extending the cultivation of common buckwheat to Mediterranean environments, we investigated the responses of two varieties to three sowing times, early spring, late spring and late summer, in rainfed and irrigated conditions. Plants were harvested at two ripening stages for forage production and at maturity for grain yield. The crop cycle lasted 82–88 days independent of sowing time, whereas the thermal time was ~1000 degree-days in early spring and late summer sowings, and 1200 degree-days when sown in late spring. Forage yield increased up to 75% between ripening stages. Early spring was the best sowing time for forage (4 t ha–1 dry weight) and grain yield (2 t ha–1 dry weight) in rainfed conditions. Late spring sowings give the highest forage yield when irrigated (6 t ha–1 dry weight), but were not suitable for producing grain, for the adverse effect of high summer temperatures on seed set and seed filling. Late summer sowings produced acceptable grain yield (1.5 t ha–1 dry weight), whereas short days and low temperatures limited forage production. Thus, in Mediterranean environments, buckwheat could be profitably introduced as a minor summer crop, sown in early spring for grain production and in late spring for forage production.
