Crop production: Plant flowers
A replicated, randomized, controlled study in 2008–2009 in a lettuce field in Salinas, California, USA, found smaller lettuces in fields with planted flower strips, compared to fields without planted flower strips. Implementation options: When lettuce plants were removed to make space for sweet alyssum Lobularia maritima flower strips, and alyssum was planted perpendicular rather than parallel to lettuce rows, lettuces were not significantly smaller than lettuces in monocultures without flower strips (50 g/head). In five other configurations, lettuces were smaller than in monoculture (38–44 vs 50 g/head). Methods: Eight plots (1 x 10 m) in each of four blocks were planted with a lettuce monoculture (control) or a combination of lettuce and alyssum (replacement or addition, in different configurations).
