The field
experiment was conducted to determine the influence of harvesting stages
and row spacing on leaf and essential oil yield response of spearmint
var. WG-SPM-Fran at Wondo Genet and Hawassa during 2014/2015. The
experiment comprised three levels of harvesting stages (flower bud
initiation, 50% flowering and full blooming) and four levels of row
spacing (30, 60, 90 and 120 cm) were used on a plot size of 3.6 cm
length and 3.6 cm width. The treatments were arranged in a factorial
Randomized Complete Block Design (RCBD) with three replications. SAS
(version 9) software was used to compute the analysis of variance. The
results revealed that the tested locations, treatments and interaction
of both factors differed markedly on the response of leaf and oil yield
response of spearmint var. WG-SPM-Fran. Of the two locations tested,
location Hawassa showed the highest fresh leaf yield/row, dry leaf
yield/row and essential oil yield/ha. In contrast, location Wondo Genet
had greater percent essential oil content as compared to Hawassa. In
case of treatment, the highest fresh leaf yield/row, dry leaf yield/row
and fresh leaf yield/ha were obtained when it was planted at 120 cm row
spacing and harvested at 50% flowering stage; whereas, the highest dry
leaf yield and essential oil yield/ha were obtained when it was planted
at 90 cm row spacing and harvested at full blooming stage. Moreover, the
combined main effects showed that, the highest dry leaf yield/ha and
essential oil yield/ha were obtained when it was planted at Wondo Genet
at 90 cm row spacing and harvested at full blooming stage. Therefore,
for greatest dry leaf and essential oil yield production it is better to
plant this variety at Wondo Genet at 90 cm row spacing and harvested at
full blooming stage. How to cite this article: Degu B, Amano S, Mengesha B (2017). Leaf and Essential oil yield response of Spearmint (Mentha spicata var. WG-SPM-Fran) under varying harvesting stages and row spacing. Acad. Res. J. Agri. Sci. Res. 5(4): 284-290
