Researchers recommend best practices for commercial production in water-limited regions
Marketable yield, yield components, quality, and phenolic compounds of artichoke heads were investigated in response to three irrigation regimes and four nitrogen rates under subsurface drip irrigation. Results showed that irrigation was more effective than N management for optimizing artichoke yield. Time of harvest had the largest effect on artichoke nutritional quality, followed by deficit irrigation. The study will help introduce artichoke cultural practices into commercial production in water-limited regions of the southern United States.
