Basic fertilization and nitrogen top-dressing of basil was studied in 1984 and 1985 at the Department of Horticulture, University of Helsinki. The total N doses applied were 0, 0.2, 0.4, 0.8, 1.2 and 1.6 kg N/100 m2. In 1984 the plants were of a mixture of different fenotypes and two of those formed 85 % of the crop-stand. In 1985 the variety grown was ’Budakalasz’. The optimum basic fertilization proved to be a compound fertilizer at the rate (NPK) of 0.4—0.16—0.68 kg/100 m2. The content of volatile oils in dried herb ranged from 0.32 to 1.46 %. The total oil content was not significantly affected by fertilization except in 1984 when the fertilization decreased the oil content in the other of those two major fenotypes.

The influence of different levels of basic fertilization and nitrogen top-dressing on the herb and oil yield of dill (Anethum graveolens L.) was studied in 1984 and 1985 in Finland. The total nitrogen doses were 0, 15, 30, 40, 80, 120 and 160 kg/ha. The crop in 1984 yielded 12 000—34 000 kg/ha fresh dill herb and 10.3—21.1 kg/ha essential oil. The figures in 1985 were 10600—21 000 and 9.4—16.6 kg/ha, respectively. Of the 22 volatile components identified by gas chromatography mass spectrometry, the four most abundant compounds were analysed quantitatively. These compounds were a-phellandrene, 3,6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran, β-phellandrene and limonene, composing 70—95 % of the total aroma content. The optimum basic fertilization for the herb yield proved to be a compound fertilizer of the rate of 40-16-68 kg NPK/ha. The small nitrogen doses (30—40kg N/ha) gave also good results in respect to oil yield and the amount of 3,6-dimethyl-2,3,3a,4,5,7a-hexahydrobenzofuran, the most important aroma compound in the dill herb.

Fertilization of dill and basil was studied in 1984 and 1985 in Helsinki, both basic fertilization and N top-dressing being included. The total N doses were 0, 0.15, 0.3, 0.4, 0.8, 1.2 and 1.6 kg N/100 m2 for dill and 0, 0.2, 0.4, 0.8, 1.2 and 1.6 kg N/100 m2 for basil. The optimum basic fertilization for dill and basil was a compound fertilizer of the rate (NPK) of 0.4—0.16—0.68 kg/100 m2. In one year basil received a benefit from N top-dressing corresponding to total application of 0.8 kg N/100 m2. Estimating the yield by the amount of N fertilizer indicated that dill yield would increase up to the fertilizing rate of 1.15 and basil yield up to 1.0 (in 1985) or 1.50 (in 1984) kg N/100 m2 after which the herb yields will decrease. The dry matter content of dill decreased and the nitrate concentration of both dill and basil increased as the fertilization increased. Basil was severely damaged by fungus diseases, the more fertilization was applied.

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.

To determine the importance of bushel weight as a factor in grading, 51 samples of Sunrise and 34 samples of Mennonite seed were examined for associations between bushel weight and other properties of commercial sunflower seed.Highly significant correlations of bushel weight with total oil content of the seed, r =.867**; percentage kernel, r =.740**; percentage oil in the kernel, r =.795**; and percentage nitrogen in the kernels, r = −.467** were obtained. Oil yield, estimated on the basis of a cake containing 5% oil and 10% moisture, was also associated with bushel weight, r =.871**. The correlation coefficients of bushel weight with iodine value, acid value, and refractive index were not significant.The present grade specifications fail to take full advantage of bushel weight as a factor in grading sunflower seed since the levels were set too low to be effective. It is suggested that the levels might well be 30 lb. for No. 1, 26 lb. for No. 2, and 22 lb. for No. 3 instead of 24 lb. for No. 1 and 21 lb. for No. 2 and No. 3. The effects of this change are discussed in relation to grading of the two varieties and the establishment of appropriate price spreads between grades.** Indicates that the 1% level of significance was attained.

Agryl P17 fiber-mulching of cold-sensitive herbal plants, basil (Ocimum basilicum L.) and marjoram (Origanum majorana L.), were studied at three locations in Finland (1984—1985). The growing sites were Helsinki (60° 14' N), Sahalahti (61° 28' N), and Inari (69° 04' N) for both species in 1984, and Helsinki for marjoram in 1985. Agryl P17 mulching increased basil yield at all locations. The uncovered basil yielded approximately 54 kg/100 m2 and when grown under the mulch, more than three fold, 191 kg/ 100m2. In the north (Inari), however, basil and marjoram did not give practically any yield. Marjoram did not benefit from mulching either in the south: the yield was 96 kg without and 80 kg/100m2 with mulching. The vegetation under the mulch was severely affected by fungus diseases. The volatile oil content in the dried basil herb ranged from 0.46 to 0.93 %. There were no significant differences in the total oil content whether basil was grown with or without Agryl P17. The oil content in marjoram ranged from 1.94 to 2.55 % the total content being significantly higher when grown under the cover.

Japanese cornmint (Mentha canadensis L.) is a major essential oil crop grown in Asia, South America, and to a limited extent in eastern Europe. Japanese cornmint oil is the only commercially viable source for crystalline menthol. We hypothesized that the length of the distillation time (DT) will have an effect on Japanese cornmint essential oil content and composition. Therefore, the objective was to evaluate the effect of eight DTs (1.25, 2.5, 5, 10, 20, 40, 80, and 160 min) on essential oil content and composition. The essential oil content (0.43% to 1.06% range) reached maximum at 10 min DT; further increase in DT did not significantly increase essential oil content. The concentrations of alpha-pinene (0.14% to 0.76% range), beta-pinene (0.23–0.81), 3-octanal (0.19–0.34), limonene (0.69% to 1.53%), eucalyptol (0.06% to 0.12%), isopulegone (0.42% to 0.56%), and isomenthone (4.4% to 5.7%) were highest at 1.25 to 5 min DT and generally decreased to their respective minimums at 160 min DT. The concentration of menthone (4.3% to 6.3%) was highest at 1.25 min DT, decreased at 2.5 min, and was lowest at 10 to 160 min DT. The concentration of piperitone (0.98% to 1.27%) was lowest at 1.25 min DT and higher at 5 to 40 min DT compared with other DTs. The concentration of menthol (74% to 79%) was low at 1.25 min, then increased at 10 to 80 min DT, and reached a maximum at 160 min DT. Generally, the yield of most individual essential oil constituents was lower at 1.25 min DT relative to the other DT and reached maximum at 10 to 20 min DT. The yield of menthol was low at 1.25 to 2.5 min DT and rose at 5 min to 160 min DT. The results suggest that different DTs can be used to maximize recovery of certain constituents. Also, the results demonstrated that there are no oil yield gains after 20 min DT, which is much lower than the usual distillation time of 60 min or more. This study can be used as a reference when comparing reports in which different DTs were used.

Field experiments were carried out during Kharif season of 2015 and 2016 to study the influence of FYM, inorganic fertilizers and bio-fertilizers on fresh herbage yield, quantity and quality of essential oil of sweet basil (Ocimum basilicum). Nine treatments with  three replication were adopted in a randomized block design to find out the effect of different levels of N applied through FYM (100, 75 and 50% of the recommended N along with and without bio-fertilizers), recommended dose of NPK (160:80:80 kg ha-1), recommended FYM (10 t ha-1) + NPK (160:80:80  kg ha-1) and control (recommended  FYM (10 t ha-1) on fresh herbage and oil yield, oil content and oil quality of sweet basil (Ocimum basilicum L.). Pooled results revealed that application of recommended FYM (10 t ha-1) along with recommended NPK (160:80:80 kg ha-1) recorded the highest fresh herbage yield (39.95 and 19.37 t ha-1), essential oil content (0.48 and 0.45%) and essential oil yield (199.7 and 107.58 kg ha-1) in the main crop and ratoon, respectively. With respect to oil quality, bio-fertilizer has a good impact on oil quality, that highest percentage of Methyl chavicol was recorded with application of recommended FYM (10 t ha-1) + recommended N through FYM along with bio fertilizers in the main crop of 2016 (63.78%) and in the ratoon (59.39 and 59.67%) of 2015 and 2016, respectively.

In the present study, chemical compositions of essential oils from seeds and leaves of laurel (Laurus nobilis L.) were evaluated using GC-GC/MS system. Sixty nine different compounds were identified constituting 86.7% of the total oil from the seed, while 76 compounds were determined, constituting 95.8% of the total oil extracted from the leaves. The major compounds of essential oil from laurel seeds included eucalyptol (17.2%), α-terpinyl acetate (9.0%), caryophyllene oxide (6.1%), spathulenol (5.0%) and methyl eugenol (4.2%), constituting 41.5% of the total oil. However, eucalyptol (18.0%), α-terpinyl acetate (13.1%), sabinene (7.8%), α-pinene (4.5%), 2 (4-methoxyphenyl)-N,N,2-trimethyl-1-pyrroline (4.4%) were identified as the major compounds in the oil from laurel leaves, constituting 47.8% of the total oil. Eucalyptol and α- terpinyl acetate, belonging to monoterpenoids, were determined in the highest concentrations within both oils. However, the other principle compounds differ between the two volatile oils.
