Crop-ecology and nutritional variability influence growth and secondary metabolites of Stevia rebaudiana Bertoni.

摘要: Background Plant nutrition and climatic conditions play important roles on the growth secondary metabolites of stevia (Stevia rebaudiana Bertoni); however, nutritional dose is strongly governed by soil properties growing region. In northern India, interactive effects crop ecology plant yield are not yet properly understood. Thus, a field experiment comprising three levels nitrogen, two phosphorus potassium was conducted at locations to ascertain whether spatial variability would dominate leaf profile stevia.
