Citrus fruits are a popular source of vitamin C and are widely consumed both fresh and in processed forms, such as juice, marmalade, and dried fruit. The citrus industry plays a significant role in economies worldwide, with major producers including countries like Brazil, the United States, China, and Spain. The industry faces various challenges, including disease outbreaks, climate change, and market fluctuations, which can impact production and profitability. Research in the citrus industry often focuses on developing new varieties with improved disease resistance, increasing crop yields, optimizing irrigation and fertilization practices, and improving post-harvest handling and storage techniques. Additionally, research in this field also explores sustainable farming practices and ways to minimize the environmental impact of citrus cultivation.
