Essential Oil Yield

Aromatic plants can benefit from the use of treated wastewater to satisfy their water requirements, but the effects on the essential oil yield and quality need an assessment. The aims of this study were to assess the effects of freshwater and treated wastewater obtained from a Sicilian (Italy) pilot-scale horizontal subsurface flow constructed wetland system on plant growth and yield, essential oil yield and composition of oregano (Origanum vulgare ssp. hirtum (Link) Ietswaart) and soil characteristics. The system had a total surface area of 100 m2 and was planted with giant reed and umbrella sedge. An experimental open field of oregano was set up close to the system. Two years and two different sources of irrigation water were tested in a split-plot design for a two-factor experiment. Treated wastewater was characterized by higher values of mineral and organic constituents than freshwater. The results highlight that short-term irrigation with freshwater and treated wastewater, in both years, led to increased plant growth, dry weight and essential oil yield of oregano plants. However, it did not significantly affect the essential oil content and composition in comparison with the control. Furthermore, the year and source of irrigation water did not significantly vary the chemical composition of the soil. Our results suggest that treated wastewater can be considered an alternative to freshwater for the cultivation of oregano due to the fact that it does not greatly influence the yield quality and quantity of this species in the short-term.

Ocimum basilicum L. is an herbaceous plant from the Labiate family that used fresh, as a spice, and as a medicinal plant. Mulch is technique capable of reducing evaporation from the surface of the soil in basil production systems; it has more impacts on yield and essential oil quality of a basil crop. This research was performed in order to study the effects of different mulch types and irrigation regimes on various growth parameters and the essential oil content of basil. Treatments included two mulch types (black plastic, wood chips, and control) and three irrigation levels (100, 80, and 60% of water requirements, calculated by evaporation pan class A), following a randomised complete block design with four replications. Results showed that the effect of irrigation on fresh weight, dry weight, leaf relative water content, leaf area, and essential oil yield was significant (P<0.05). The effect of mulch on fresh weight, dry weight, leaf area, inter-node distance, number of branches, and essential oil yield was significant (P<0.05). Interaction between irrigation and mulch on inter-node distance, fresh weight, dry weight, and leaf area was significant (P<0.05). This study identified wood chips as the best mulch treatment. The highest dry weight yield (38.35 g/plant) and the highest essential oil yield (82.83 L/ha) resulted when wood chip mulch was used in combination with irrigation at 100% of the water requirement. This combination also resulted in the highest water productivity in basil production.   Highlights - Different levels of irrigation alone did not always increase plant growth and yield of basil. - Different levels of mulch alone did not always increase plant growth and yield of basil. - Different levels of irrigation and mulch in combination used, increased, growth and essential oil yield of basil. - This study identified wood chips as the best mulch treatment. - The highest essential oil yield resulted with wood chip mulch and irrigation at 100% of the water requirement.

AbstractTo study the effect of farmyard manure and plant growth regulators on yield and essential oils of dragonhead, an outdoor experiment was conducted in Maragheh, Iran. The experiment was carried out based on randomized complete block design with three replications. Three amounts of farmyard manure (FYM) including 0, 10 and 20 t/ha together with foliar growth regulators including 0, salicylic acid (SA), ascorbic acid (ASc) and SA + ASc were used. The results revealed that application of 10 and 20 t/ha farmyard manure significantly increased plant height and the number of lateral stems. However, application of 20 t/ha led to the increase of the number of the main and flowering stems, biomass and essential oil percentage of dragonhead compared to control. The effect of growth regulators on the number of lateral and flowering stems, and biomass was significant: foliar application of SA and ASc separately or in combination increased the number of lateral stems; however, the number of flowering stems and biomass of dragonhead increased only when both growth regulators were used in combination (SA + ASc). The results also indicated that the highest length of inflorescence (13.57 cm) and essential oil yield (41.83 kg/ha), by 31.4 and 126.3% increment, respectively, were observed under foliar application of 20 t/ha farmyard manure together with SA + ASc application compared to the control.

Field experiment was conducted at Central Institute of Medicinal and Aromatic Plants (CIMAP), Lucknow to evaluate the growth and yield of geranium and garlic in intercropping system. Maximum dry matter accumulation was noticed during 120-135 DAP. Dry matter accumulation in geranium paired sole was almost equal to geranium paired intercrop. Application of phosphorus at 40 kg P<sub>2</sub> O<sub>5</sub> ha<sup>−1</sup> and 30 kg ZnSO<sub>4</sub> ha<sup>−1</sup> significantly increased the dry matter accumulation of plants over control at all the stages of crop growth. Bulb yield of garlic was found to be increased with increase in the application of phosphorus up to 40 kg P<sub>2</sub> O<sub>5</sub> ha<sup>−1</sup> and zinc upto 30 kg ZnSO<sub>4</sub> ha<sup>−1</sup>. The essential oil yield of geranium pure crop significantly improved over essential oil yield of intercropped geranium . Uptake of Zn also increased significantly upto 40 kg P<sub>2</sub> O<sub>5</sub> ha<sup>−1</sup>. Higher rates of P decreased the Zn uptake by the plants. Application of 30 kg ZnSO<sub>4</sub> ha<sup>−1</sup> showed a significant response on the herb and oil yield over no zinc application. The net return from geranium and garlic in paired intercropping system was Rs 2,58,564.95 being higher other cropping system. Thus intercropping garlic with geranium proved economical.
