In the heart of Iraq, researchers are unlocking new potential for a versatile crop that could boost farmers’ incomes and contribute to sustainable agriculture. Roselle (Hibiscus sabdariffa L.), an annual shrub with a multitude of uses, is at the center of a promising study led by Sudad K. Al-Taweel from the Department of Field Crops at the University of Baghdad. The research, published in the *Basra Journal of Agricultural Sciences* (translated from Arabic: *Maǧallaẗ al-baṣraẗ al-ʻulūm al-zirāʻiyyaẗ*), explores how organic and chemical fertilizers, combined with a biostimulant, can enhance Roselle’s growth, yield, and chemical composition.
The study, conducted over two seasons (2020 and 2021), investigated the effects of organic manure, chemical fertilizer, and a biostimulant compound called Appetizer (App) on Roselle plants. The findings revealed that foliar application of App significantly improved all parameters studied, with even greater enhancements when combined with fertilization. “Spraying Roselle plants with App positively increased all parameters studied over the control,” Al-Taweel noted. “Such an increase was greatly enhanced when the App was combined with fertilization.”
The research highlighted that the highest growth characters, chemical constituents, ascorbic acid, and carbohydrate values resulted from half doses of chemical and organic manure combined with 4 and 6 g L-1 of App. Interestingly, organic manure, whether applied solely or combined with App, yielded high values that were often superior to those achieved with chemical fertilizer alone. This finding underscores the potential of organic farming practices in achieving comparable, if not better, results than conventional methods.
The commercial implications of this research are substantial. Roselle is a multipurpose crop with significant economic potential, both in export and local markets. By optimizing its growth and yield through sustainable practices, farmers can increase their income and contribute to a healthier agricultural ecosystem. “Organically speaking, it is recommended that if there are fewer harmful and healthier products in agriculture, organic manure, either alone or combined with App, is still of high value for plant yield, especially when integrated with 4g L-1 App,” Al-Taweel suggested.
This study not only sheds light on the benefits of integrating biostimulants with organic and chemical fertilizers but also paves the way for future research in sustainable agriculture. As the world increasingly turns to eco-friendly practices, the findings from this research could shape the future of crop cultivation, ensuring higher yields and better quality produce while minimizing environmental impact.
In an era where sustainable agriculture is more critical than ever, this research offers a glimpse into the future of farming—one where innovation and tradition converge to create healthier, more productive crops. As Al-Taweel’s work continues to gain traction, it may well inspire a new wave of agricultural practices that prioritize both economic viability and environmental sustainability.
