Different Parts

Basil is an aromatic, medicinal, culinary, and multifunctional herb which is grown in different parts of Ethiopia. Although the oil distilled from the herb, as well as its herbal yields, are a crucial input in the pharmaceutical industry and for culinary purposes, the yield obtained is below its potential due to various challenges. Genotype and plant spacing are two of the factors which contribute to the low production of the crop. A field trial was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) in 2016 and 2017 to assess the effect of genotype and plant spacing on essential oil yield and other yield-related traits of this important herb. Four promising genotypes (BO-1, BO-3, BO-4, and BO-5) and three plant spacings (20, 30, and 40 cm) were studied in a 4 × 3 factorial design arranged as randomized complete blocks (RCBD) with three replications. Data on plant height, leaf area, number of primary branches, essential oil content and oil yield were collected and analyzed. The analysis of variance revealed that there were highly significant (<em>p</em> &lt; 0.01) interaction effect of genotype with plant spacing for all parameters tested. The maximum essential oil yield (7.88 kg ha<sup>−1</sup>) was obtained from genotype BO-5 at 30 cm spacing, whilst the least (2.68 kg ha<sup>−1</sup>) was recorded from BO-1 at 40 cm spacing. The maximum oil content (101 mL g<sup>−1</sup>) was gained from BO-1 at 20 cm, but BO-3 at 30 cm spacing recorded the least oil content though there were no significant differences between the three treatment combinations. Further studies at different locations and seasons will be important to for future local recommendations.

Abstract The aim of the present study was to determine the effects of rainfed and supplemental irrigation, and sowing period (SP) treatments on Coriander (Coriandrum sativum L.) yield, essential oil content and umbel heights by applying new agro-technologies (TDR-sensors for soil moisture (SM), GIS, Precision Agriculture, soil-hydraulic analyses and Geostatistical models) for yield and SM root zone geospatial modelling and two-dimensional GIS mapping. Results of laboratory analysis indicated a suitable soil for coriander's growth and revealed that field's soil was characterized Sandy Clay Loam(SCL) with mean values: Soil Organic Matter(SOM) = 1.70%, bulk specific gravity = 1.42 g·cm−3, Plant Available Water = 0.129 cm·cm−1, pH = 7.10 and cation-exchange capacity(CEC) = 19.3 cmol·kg−1. The two-way ANOVA statistical analysis (P = 0.05) results revealed that the irrigation treatments (IR1:rainfed, IR2:rainfed plus supplemental irrigation[best]), and the SP treatments (SP1:October's last week, SP2:November's first week[best]) significantly affects Coriander's seed yield and essential oil content, but the SP have no significant effect on plant's umbel height (P = 0.873). Supplemental irrigation, using a limited amount of water, if applied during the critical crop growth stages, can result in substantial improvement on seed yield (+284.934%), essential oil content (+125.396%) and plant's umbel height (+117.929%).

"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."

Lomatium dissectum (Torrey & Gray) Mathias & Constance, a perennial from the Apiaceae, has been among important traditional medicinal plants of the native North Americans for thousands of years. Preparations from the tuber are used to improve the general well-being, immune system, and adaptation. Its formulations with other herbs is used in cosmetics for skin regeneration, and treatment of psoriasis. L. dissectum is normally collected from the wild for commercial processing. As the demand for the raw material is increasing, there is a growing danger of genetic erosion of the wild species. In addition to this, wild collection does not guarantee regular availability, quality, and exact botanical identity. The objective of this investigation was, therefore, to study the variability in tuber and seed yield, essential oil content, and find effective method of increasing seed germination and develop improved cultivars, suitable for commercial cultivation. We found significant variations in tuber and seed yield/plant, and essential oil content in the tubers. The color of the oil varied from pale green to deep green. The intensity and composition of the aroma of the oil obtained from individual plants was also found to vary significantly. We carried out investigations with microbial seed pretreatment under laboratory and field conditions, with varying concentrations and length of seed soaking. The microbial (RIBAV™) seed pretreatment for 20 min, at a concentration of 20% under laboratory conditions resulted in a 99.2% germination, while control variants had only 18% to 26% seed germination. Pretreated seeds took significantly less time for germination compared to the control. Similar results were recorded for seeds sown under field conditions. Seedlings from pretreated seeds showed vigorous growth and better field establishment, compared to the control variants.
