Agriculturecitrus refers to the branch of agriculture focused on the cultivation of Citrus species, including orange, lemon, lime, grapefruit, and mandarin varieties. It encompasses breeding, propagation, orchard management, harvest, processing, and marketing of citrus fruits and by-products.

Citrus crops require warm, frost-free climates and reliable rainfall or irrigation. They grow best in well-drained loams with slightly acidic to neutral pH (roughly 5.5 to 6.5). They are sensitive to frost and drought stress, and producers often rely on irrigation systems such as drip irrigation to manage water efficiently.

Commercial citrus production typically uses grafted trees on disease-resistant rootstocks to improve vigor and tolerance to soil conditions. Tree spacing, pruning, mulching, and timely fertilization (notably nitrogen, potassium, and micronutrients) support yield and fruit quality. Integrated pest management reduces chemical inputs and promotes sustainable control of pests and diseases.

Common challenges include diseases such as huanglongbing (citrus greening), citrus tristeza virus, and cankers, as well as pests like psyllids, aphids, scale, and mites. Management combines monitoring, biological controls, targeted pesticides, sanitation, and quarantine measures to protect crops and maintain market access.

Harvesting occurs at fruit maturity identified by color and sugar content. Postharvest handling emphasizes careful picking, cooling, cleaning, and packing to extend shelf life. Citrus by-products include essential oils from peels and pectin from processing.

Globally, citrus is a major agricultural commodity with leading producers including China, India, the United States, Brazil, Mexico, Spain, and Argentina. The sector faces climate variability, water scarcity, and disease pressures, motivating advances in breeding, irrigation efficiency, and sustainable orchard practices.
