Influence of Plant Population Density on Growth and Yield of Stevia (Stevia Rebaudiana Bertoni L.)

چکیده مقاله:
Objective: An experiment was conducted at Wondo Genet Agricultural Research Center in the production season of 2013/14 and 2014/15 with the objective of identifying the best combination of intra and inter-row spacing for optimum plant population density of stevia. Methods: The experiment was conducted using five intra-row spacing (20cm, 25cm, 30cm, 35cm, and 40cm) and three inter-row spacing (40cm, 50cm and 60cm) with total treatment combination of fifteen that were laid out in factorial RCBD design with three replications. In 2013/14 cropping season the maximum fresh leaf weight (19467kg ha-1), fresh above-ground biomass (25002kg ha-1) and dry leaf weigh (7834kg ha-1) were obtained from the combined pacing of 20cm intra-row and 40cm inter-row spacing. In 2014/15 cropping season, the maximum fresh leaf weight (16470.1 kg ha-1) and (14433.9kg ha-1), fresh above-ground biomass (27547kg ha-1) and (23619.8kg ha-1) and dry leaf weight (4773.7 kg ha-1) and (4314.0 kg ha-1) were obtained from 20cm intra-row and 40cm inter-row spacing respectively. Results: Although the study showed that the highest Stevia herbage yield per unit area was recorded from the combined spacing of 20cm intra-row and 40cm inter-row spacing, considering the difficult condition we met during weeding and watering, we, therefore; suggest that the best combined intra-row and inter-row spacing for Stevia is 25cm x 40cm to attain maximum yield under appropriate management conditions at Wondo genet and similar locations.

Is Stevia rebaudiana Bertoni a Non Cariogenic Sweetener? A Review.
Stevia rebaudiana Bertoni is a small perennial shrub of the Asteraceae (Compositae) family that is native to South America, particularly Brazil and Paraguay, where it is known as "stevia" or "honey leaf" for its powerful sweetness. Several studies have suggested that in addition to their sweetness, steviosides and their related compounds, including rebaudioside A and isosteviol, may offer addit...

This study was conducted to compare the effects of foliar spray and rhizosphere irrigation with purple phototrophic bacteria (PPB) on growth and stevioside (ST) yield of Stevia. rebaudiana. The S. rebaudiana plants were treated by foliar spray, rhizosphere irrigation, and spray plus irrigation with PPB for 10 days, respectively. All treatments enhanced growth of S. rebaudiana, and the foliar me...
