Best Varieties of Basil for Growing in Hydroponics

As the popularity of fresh culinary herbs increases, growers are looking to year-round production methods to supply distributors and local consumers. In colder climates, culinary herb growers rely on controlled indoor environments and often employ hydroponic production techniques. A new study of basil varieties grown using two popular techniques found that plant performance is more likely related to the choice of cultivar than the type of hydroponic system used.

Kellie Walters and Christopher Currey from the Department of Horticulture at Iowa State University studied basil cultivars grown in the two most prevalent types of hydroponic systems used for growing leafy crops: nutrient flow technique (NFT) and deep flow technique (DFT). A report of their experiments was published in the October 2015 issue of HortTechnology. Walters and Currey selected seeds of 35 cultivars of basil representing several species, and transplanted seedlings 2 weeks after sowing into either NFT or DFT systems. They evaluated the basil when the majority of plants were considered harvestable.

"Our results showed that basil growth and development were affected by either cultivar or hydroponic production system, but not the interaction between production system and cultivar," the authors said.
