MAX FACTS growing tips, news and trivia Tasty Tomatoes Tomatoes are a $2 billion crop in the United States, but a common complaint is that the varieties in supermarkets often lack the flavor of locally grown varieties. To improve flavor, breeders need to know more about the types of tomatoes that hold the greatest potential for enhancing taste. USDA researchers are exploring the tomato’s diversity in a study designed to help breeders develop tastier tomatoes. The team raised 173 varieties on test plots in North Carolina, trained 10 volunteers in sensory analysis and asked them to rate the varieties on a scale of one to five in four sensory areas: odor, taste, flavor and texture. Findings show that although thousands of compounds go into determining flavor and other characteristics, two components play a key role: the amounts of sugar and acid.

In his system, pipes galore run between fish tanks, storage tanks and the plant beds, which are made up of small clay pebbles. Roots of his tall cherry tomatoes plants don’t have to branch out as far because all the nutrients are delivered right to them. The fish tacos that resulted were a resounding success, says Judy Klutts of Wadsworth Hall Dining Services. “We combined them with coleslaw made with carrots and cabbage from our garden, so it really was a sustainable meal.” (Source: mtu.edu) Hooked on Hawaiian Aquaponics The Hawaii Department of Agriculture, in cooperation with the Aquaculture Program of the University of Hawaii, is surveying grocery retailers and restaurants in Hawaii to explore the viability of aquaponic farming in the marketplace. They are looking at several factors, such as market acceptance, demand level, preferred product form, packaging and price points for produce and fish produced by aquaponic farms. Research will help farmers better understand the benefits and viability of aquaponics as a method for raising fish and specialty crops simultaneously. This is the first aquaponic project ever awarded a grant through the USDA’s Federal-State Marketing Improvement Program. A wide variety of foods, such as lettuce, beans, broccoli, cucumbers, peas, herbs, strawberries, melons and tomatoes, all flourish through aquaponic farming.
