| Abstract Stevia (Stevia rebaudiana Bertoni) is gaining attention due to its sweetening power. The stevia crop is still relatively unknown in Europe, and very little is known about its nutrient requirements. Therefore, agronomic studies are needed. Field trials were carried out in inland Spain in 2014 and 2015, in order to evaluate the yield, quality, and nutrient requirements of stevia according to planting density and harvest regime, under a continental Mediterranean climate. In 2014, the dynamics of growth, quality and accumulation of nutrients were studied during the vegetative period according to three planting densities (5.0, 7.5, and 10.0 plants m-2). No significant influence was found. The steviol glycosides concentration decreased sharply at... |
