Performance of sage (Salvia officinalis L.) for morpho-agronomic and chemical traits in different agro-ecologies of Ethiopia

Abstract

B.M. Kassahun et al. / International journal of Advanced Biological and Biomedical Research (2015) 3(4) 351-360 352 AbstractThis experiment was conducted with the objective of evaluating the performance sage (Salvia officinalis L.) in different agroecology of Ethiopia for morpho-agronomic and chemical traits at Wondo genet, Hawassa, Qoqa and Holleta for two years from 2011/2012 to 2012/2013 cropping seasons. Data on plant height, branch number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground biomass/plant, fresh leaf weight/ha, essential oil (EO) content and EO yield/ha were collected from four locations arranged in randomized complete block design with four replications. Growing location demonstrated a significant influence (P<0.05) on the performance of all the parameters considered. With increasing year, the performance of Sage was significantly affected (P<0.05) only on three of the nine traits. The interaction between location and yea was significant for seven of the nine traits. The overall average value of plant height, branch number/plant, leaf number/plant, fresh leaf weight/plant, fresh stem weight/plant, above ground biomass/plant, fresh leaf weight/ha EO content and EO yield/ha of sage across the tested location and years ranged from 47.7-66.9 cm, 70. 13-262.07, 619.7-4046.2, 159.13-506.31 g, 63.77-279.93 g, 221.6-743.8 g, 2772-14064 kg, 1.11-1.70% and 30.67-240.03 kg, respectively. The maximum for all the characters were recorded at Hawassa and Wondo Genet except for branch number which was found tall at Holleta. Most of the characters are statistically the same over the testing years; however, plant height, branch number and leaf number/plant demonstrated a respective percent increase value of 21.3%, 50.19% and 71.98% during the first testing year.

Influence of Soil Types on the Morphology, Yield, and Essential Oil Composition of Common Sage (Salvia officinalis L.)

“…According to our results, the seasonal variation, the location with different soil types, and the harvesting time have significant impacts on the growth parameters of common sage. These confirmed the results of Kassahun et al (2015) [17]. The morphological parameters showed the superior effect of Chernozem soil compared to the Fluvisol (Table 3).…”

“…Among the soil properties, the macronutrient, pH, and carbonated lime are correlated to the morphological parameters positively, as was reported in the study of Kassahun et al [17]. The Chernozem soil had higher macroelement content than the Fluvisol, and there was a strong correlation between the nutrients and the plants' growing parameters, as was reported earlier by Soltanbeigi et al [38] in a greenhouse experiment.…”

“…In an Ethiopian study, the influence of different soil types was examined on sage (sand clay loam (Nitosol), sandy loam (Andosol), clay soil, and redbrown clay loam (Nitosol)). The maximum plant height was observed during the cultivation under sand clay loam; however, the maximum fresh yield (14,064 kg/ha) and essential oil content (1.7%) were resulted by sandy loam [17]. Under Chernozem soil, the relative chlorophyll content (SPAD, Soil Plant Analysis Development value measured by SPAD 502 chlorophyll meter, Konica Minolta Ltd., Tokyo, Japan) of sage was 1.5 times higher, and the dry leaf weight per plant was 4 times higher than on the Fluvisol.…”
