Wondo Genet area, which is located in the Sidama zone of south Ethiopia, is characterized by a rapidly increasing human population and scarcity of arable land per household. There is a need for developing an efficient cropping system to use the limited land efficiently and to enhance food security. An experiment was, therefore, was conducted at Wondo Genet Agricultural Research Center under irrigated during the 2018 cropping season to examine the growth and yield of sweet basil under different planting densities and row arrangements in tomato-sweet basil Intercropping System. The experiment was conducted with two basil row arrangements (one tomato row alternating with one basil row (1T:1B) or with two basil rows (1T:2B)) and four basil population densities (66666, 50000, 33333 and 16666 plants.ha<sup>-1</sup>) factorial arrangement in RCBD with three replications each consisting of ten treatments. Results of the study indicated that the row arrangement by planting density interaction significantly influenced the yield of basil with the maximum dry herbal (341.49 kg.ha<sup>-1</sup>) and essential oil (22.86 kg.ha<sup>-1</sup>) yields were recorded at 100% basil population density with a 1T:2B row arrangements. The cropping system significantly influenced the essential oil content and essential oil yield of basil. The highest essential oil content (1.26%) and essential oil yield (21.83 kg.ha<sup>-1</sup>) of basil were obtained at sole planting compared to that of intercropping (0.96%) and (15.36 kg.ha<sup>-1</sup>) with tomato showing 23.81% and 29.64% reduction, respectively. Therefore, intercropping 100% basil population in tomato by 1T:2B row arrangements could be recommended for Wondo genet and similar agroecology area, based on its better compatibility and productivity.

<p><span>A field experiment was conducted to evaluate yield and some qualitative characteristics of four cultivars of sweet basil treated with different levels of nitrogen fertilizer. The experiments were located on the Agricultural Research Station of Khorramabad, Iran, during the 2016-2017 growing season. Treatments were arranged in factorial split-plot-in time in randomized complete block design with three replications. Experimental treatments were four cultivars of sweet basil (<em>Ocimum basilicum</em> ‘Italian Large Leaf’, <em>O. basilicum</em> ‘Mobarakeh’, <em>O. basilicum</em> ‘Cinnamon’ and <em>O. basilicum </em>‘Thai’), three levels of nitrogen fertilizer (0, 100 and 200 kg ha<sup>-1</sup> urea) and three harvests. The highest total dry mass (3482.4 kg ha<sup>-1</sup>) was related to ‘Italian Large Leaf’ with the application of 200 kg ha<sup>-1</sup> urea at the second harvest. The maximum (26.79 kg ha<sup>-1</sup>) essential oil yield belonged to 100 kg ha<sup>-1 </sup>urea. The highest concentrations of main constituents of essential oil, except methyl chavicol, 1,8-cineole and methyl cinnamate were obtained by control (without nitrogen fertilizer). Italian Large Leaf cultivar and application of 100 kg ha<sup>-1</sup> urea are recommended to access an acceptable agricultural yield and essential oil yield in sweet basil under the environmental condition similar to Khorramabad</span></p>

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.

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.

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.

The study was carried out from June to December, 2014. The objective of this study was to determine a suitable topping time for sweet basil variety grown in the net house at Research and Development Center for Hi-Tech Agriculture Ho Chi Minh City. A two-factorial experiment was designed by the CRD (Completely Randomized Design) with three replications. Factor A consisted of three sweet basil varieties (TN12 as Control, TN33, and TN39) and the factor B was the topping times including untopping (the control), the topping when sweet basil at the four-leaves, at the six-leaves and at the eight-leaves period. The results showed that variety TN39 was suitable for extracting basil-oil because of the highest yield (3,365.4 kg/1,000 m2) and high total essential oil content (0.25%). Variety TN12 could be grown for fresh-eating spicy. The variety TN12 resulted in the fairly high yield (1,955.4 kg/1,000 m2) and total essential oil content (0.20%) with good taste. Topping the basil plant at the six-leaves period reached the highest yield of 2,172.3 kg/1,000 m2.

ABSTRACT: Pogostemon cablin (Blanco) Benth. is an aromatic species popularly known as patchouli. The essential oil rich in patchoulol extracted from leaves is used by the pharmaceutical industries. The objective was to investigate the effects of shade nets and shading intensities on P. cablin growth, anatomy, chemical composition and essential oil content. The experiment was conducted with two types of shade nets (black and Aluminet), three light intensities (30, 50, and 70% shading) and full sun. The different light intensities influenced the growth and the essential oil yield, and chemical composition. Patchouli plants grown in an environment with shading showed higher values for the leaf, stem, root ant total dry weights compared to full sun. At 50% of shading, Aluminet provided gain in stem and total dry weights. Aluminet and black net at 50 and 70% of shading enhance essential oil yield. Patchoulol and pogostol contents were higher under full sun, and, black net and Aluminet at 50% shading. The environment for patchouli cultivation can be improved by use shade nets, especially with Aluminet at 50% of shading.
