Leading the Lettuce industry
Rijk Zwaan offers future-proof solutions for growers. Lettuce production is evolving rapidly. Labour shortages in mature markets drive mechanisation in transplanting and harvesting. At the same time, stricter limits on water, pesticides and fertilisers accelerate the shift to hydroponics. These trends create strong demand for innovative lettuce varieties with robust resistance traits – solutions that help growers stay competitive and meet sustainability goals.
