Effects of nitrogen fertilization on growth and yield of diterpene glycosides in stevia (Stevia rebaudiana Bertoni)

The effects of different nitrogen doses on dry weight yield, stevioside and rebaudioside A contents, yields were evaluated in stevia (Stevia rebaudiana Bertoni). This study was carried out at the Instituto Federal Catarinense, Rio do Sul (SC), Brazil, under decreasing photoperiods. randomized complete block design with four blocks five treatments (0, 65, 135, 200 270 kg ha-1 N) used. Variables related to yield (total weight, leaf stem number secondary branches tertiary branches, main length), growth rates area, area index, specific ratio, ratio), contents evaluated. fertilization did not affect variables yields, or A:stevioside ratio genotype 8 (G8), grown
