![]() “If growers pay attention to timing of when crops are blooming and manipulate that by planting apple varieties and strawberry varieties that don’t overlap, you can get a boost in yield that is almost equivalent to having natural habitat nearby.” “Those growers need some more sustainable agriculture options,” Grab said. But for many growers in agriculturally dense areas, increasing natural habitats is not an option. Planting natural habitats around farm fields can lead to improved health of pollinators and a boost in their services, according to research. “We are trying to figure out ways that growers can use ecosystem services to promote crop yield rather than relying on external inputs, such as fertilizers and pesticides,” said lead author Heather Grab, a doctoral student in the lab of co-author Bryan Danforth, professor of entomology. Previous research showed that strawberries can have as much as 40 percent yield increase when bees and other pollinators visit, compared with relying on wind pollination alone. The findings, published in the March 27 issue of Nature Scientific Reports, offers growers a sustainable method for boosting yields of crops that bloom around the same time as apples. But if growers time their strawberries to flower directly after a neighboring apple bloom, strawberries produce higher yields than they would if there were no apple trees nearby. ![]() When apple trees blossom, the sheer abundance of flowers attracts most of the pollinators, which leaves fewer bees for other nearby crops such as strawberries and lowers their yields. ![]() Growers who time their strawberries to bloom just after apples do can reap a better harvest, according to new research. ![]()
