After the mineral nutrition of plants was established as a scientific discipline (nineteenth century), large amounts of inorganic nitrogen (N) were used to improve crop performance. Nitrogen is an essential nutrient element for plant growth. N deficiency may cause many biochemical and physiological disorders, leading to overall plant performance reductions. The urgency to increase crop productivity in order to ensure sufficient food for most of the global population has raised the use of nitrogen fertilizers considerably in the last decades. In the main vegetable production areas, N fertilizer application rates can reach and overcome 1000 kg N ha−1. This excessive use is proven to cause a number of environmental and ecological problems within and outside farmlands (groundwater pollution, greenhouse gas emissions, eutrophication, deposition, and disruptions to natural ecosystems) and is closely monitored by European laws. Furthermore, a high nitrogen fertilization rate may cause health problems for humans because of the overaccumulation of N in vegetables, which may have deleterious effects on their biochemical composition and quality. Therefore, achieving a worldwide reduction of the total N input is a major challenge that requires sustained actions to improve nitrogen management practices (both for organic and synthetic N fertilizers), and to reduce nitrogen loss into the environment.
An increased knowledge of the mechanisms controlling the plant N economy is crucial for improving N use efficiency (NUE) and for reducing nitrogen overdose, while maintaining an acceptable yield and sufficient profit margin for the farmers. The understanding of the biological and agronomic basis of NUE in vegetable crops is still an important research issue that needs to be investigated, using innovative agronomic, analytical, physiological, biochemical, and molecular biology approaches.
This Special Issue aims to collect research papers and reviews focusing on “Nitrogen Fertilization in Vegetable Crops”. Therefore, research articles, reviews, short notes, and opinion articles related to inorganic and organic nitrogen fertilizer application and management solutions, NUE and horticultural crop yield response in open fields, protected cultivation, and in hydroponic systems are welcome for this Special Issue.
