Influence of the environment factors on the flower growth and flavour quality of saffron (Crocus sativa L.) in the semi-arid region
Mineral nitrogen (N) is a critical nutrient for increasing saffron flower yield and boosting corm multiplication, especially when soil fertility is low. However, excessive dependence on synthetic fertilizers can lead to soil degradation. Studies indicate that while mineral fertilizers quickly satisfy nutrient requirements, organic fertilizers (such as vermicompost or organic foliar fertilizers) are essential for long-term sustainability, as they improve soil structure, water retention, and microbial activity, which are crucial in nutrient-poor environments.
Our research focuses on enhancing the tolerance of saffron (Crocus sativus L.) to low-nitrogen (N) soil conditions through sustainable nutrient management—combining organic amendments (such as combining different foliar fertilizers). We use physiological and biochemical methods as well as metabolomics-based approaches to understand saffron biology under nitrogen starvation condition and how organic fertilizers improve the phytochemical content (crocin, picrocrocin and safranal) and quality of saffron.
