Michigan State University agricultural engineer Yuzhen Lu is developing advanced technologies to support Michigan’s specialty crop industries, including asparagus and blueberries. These innovations aim to address rising labor costs and improve efficiency in crop harvesting.
Michigan, known for its diverse agriculture, leads the U.S. in asparagus production, harvesting 20 million pounds annually.
However, asparagus harvesting is labour-intensive, with labor costs comprising up to 55% of total production expenses. Lu’s team is working on a vision-guided selective harvesting mechanism for asparagus, funded by a $197,000 grant from the USDA.
The technology uses a 3D camera to identify and harvest mature asparagus without damaging immature spears. This selective approach ensures optimal yield and reduces waste. “The goal is for the technology to match human pickers’ decision-making,” Lu explained.
Jamie Clover Adams, executive director of the Michigan Asparagus Advisory Board, emphasized the importance of mechanization for the industry’s future, stating, “This labor-saving device could secure Michigan’s leadership in asparagus production.”
In addition to asparagus, Lu’s team is creating a mobile vision system for blueberry management, supported by a $200,000 USDA grant. Using a phone app, growers can detect blueberry maturity and count berries by scanning orchards. This innovation simplifies harvest scheduling, saving time and increasing accuracy.
Lu’s projects, funded through 2026, address critical labor challenges while enhancing Michigan’s specialty crop production. With these advancements, growers can improve efficiency, reduce costs, and sustain their industries in a competitive market.
These efforts demonstrate MSU’s commitment to supporting agriculture through technology, ensuring Michigan farmers remain leaders in specialty crop production.
