Title: Sustainable Cultivation and Value Addition of Stevia (Stevia rebaudiana Bertoni) for a Greener Future
Abstract:
Stevia
(Stevia rebaudianaBertoni), a
natural zero-calorie sweetener, offers a sustainable alternative to
conventional sugar crops, aligning with global efforts to promote health and
environmental sustainability. The present study focuses on optimizing stevia
cultivation practices and developing value-added products to enhance its
commercial potential. The pot trials were conducted under varying agronomic
conditions to evaluate the impact of nitrogen fertilization. Two
salinity (0, 100 mM NaCl) levels and four nitrogen treatment levels (0, 0.1,
0.2, 0.3 g N kg-1soil) were applied to analyse the impact on
physiological parameters. Three replications of this pot trial were conducted
using a completely randomized design (CRD). The results indicated that nitrogen
(0.2 g N kg-1) considerably reduced H2O2and
MDA while enhancing carotenoids, chlorophylla, b,a/band antioxidants (CAT, SOD, and POD)
to significantly inhibit the negative effects of salt stress. Therefore, moderate nitrogen
application can enhance photosynthetic pigments and antioxidant activities
thereby, alleviating the toxicity of salt stress in stevia. Therefore, field
use of moderate levels of nitrogen is suggested to combat salinity in plants. The
integration of sustainable cultivation and product diversification not only
enhances farmers’ income but also supports climate-resilient agriculture and
the development of eco-friendly nutraceuticals. The findings underscore the
potential of stevia as a high-value crop contributing to both economic and
environmental sustainability within agri-food systems.
