In the heart of Egypt, a groundbreaking study is reshaping the way we think about cultivating calendula, a flower renowned for its medicinal and ornamental value. The research, led by Ouda M. I. from the Plant Protection Research Institute (PPRI) of the Agricultural Research Center in Giza, Egypt, and published in the *Journal of Scientific Research in Science*, offers a promising approach to boost yield, enhance quality, and control pests sustainably.
Calendula officinalis, commonly known as pot marigold, is in high demand due to its therapeutic properties and aesthetic appeal. However, its cultivation faces significant challenges, particularly from pests like Empoasca decipiens, which can cause substantial economic damage. The study, conducted over two growing seasons at the Experimental Farm of Qaha Agriculture Station, Qalyoubia Governorate, explored innovative solutions to these issues.
The researchers focused on two key factors: fertilizer treatments and alternative pesticides. They tested three fertilizer treatments—recommended NPK dose as control, Plant Growth-Promoting Rhizobacteria (PGPR), and NPK combined with PGPR—and six environmentally friendly pesticides: Giskanim 1% EC, Sulfur 30% Liquid, Brave A M 6% SL, KZ Oil 95% EC, Potassium Agricultural Soap, and Top Perfect 82% EC.
The results were striking. The combination of NPK with PGPR, along with the use of alternative pesticides, significantly improved the growth performance, flowering characteristics, and chemical composition of calendula plants. “The utilization of all alternative pesticides and NPK with PGPR markedly improved growth performance, flowering characteristics, and chemical composition while diminishing pest populations of Empoasca decipiens compared to the absence of alternative pesticides and other treatments,” noted the lead author.
This research has profound implications for the agriculture sector. By adopting these sustainable practices, farmers can enhance their yields and the quality of their crops while minimizing environmental impact. The use of eco-friendly pesticides and PGPR not only controls pests effectively but also promotes soil health and biodiversity.
The study’s findings could pave the way for future developments in sustainable agriculture. As the demand for organic and eco-friendly products continues to rise, these innovative approaches could become standard practice. “This research offers a blueprint for sustainable calendula cultivation that can be adapted to other crops and regions,” said the lead author.
In an era where sustainability and productivity are paramount, this study provides a beacon of hope for farmers and agricultural researchers worldwide. By embracing these practices, the agriculture sector can meet the growing demand for calendula and other crops while preserving the environment for future generations.
