max FACTS Mycorrhizal Fungi Enhance Cherry Tomato Growth Arbuscular mycorrhizal fungi (AMF) are a promising tool to improve plant nutrient use efficiency (NUE) and tolerance against abiotic stresses. Moreover, AMF can potentially increase plant productivity and reduce the negative externalities of the agricultural sector. A recent study aimed to see if AMF could positively affect not only tomato growth and productivity, but also the nutritional and nutraceutical quality of yellow-pigmented type and red-pigmented type landrace tomatoes. Turns out AMF rose fruit yield by increasing the number of fruits per plant but not of the fruit mean mass. AMF increased lycopene, total ascorbic acid, alanine, gamma-Aminobutyric acid, and branched-chain amino acids in ‘Lucariello’ varieties. In ‘Giagiù’, AMF increased calcium, zinc, ASP, GABA, and the essential amino acids arginine and lysine. In both landrace varieties, AMF improved nutrient uptake and biosynthesis of important molecules involved in the control the oxidative stress and cellular pH. — freshplaza.com Sea Vegetables: An Important New Source of Nutrition? According to aquaculture experts in Florida, sea vegetables could provide a tasty source of nutrition in the future. The native Florida vegetables that grow in salty areas near the ocean can be cultivated in fish farms; crops like these could provide a new sustainable and environmentally friendly source of nutrition. Megan Davis, professor of aquaculture at Harbor Branch Oceanographic Institute in Fort Pierce, recently led a 10-week study to determine the best growing conditions for sea vegetables. Plants in the study were sea asparagus (which looks almost like regular asparagus), sea purslane (harvested for the fleshy leaves on long red stems), and saltwort, a smaller frilly plant. The plants are high in minerals, such as zinc and iodine, and vitamins, but Davis notes she is awaiting a detailed nutrition analysis from the harvest. Besides Florida, sea vegetables are native to other coastal regions around the world. — gephardtdaily.com Turning School Buses into Greenhouses A Canadian woman and her family came up with a perfect solution for repurposing old school buses, and it’s benefiting both the environment and the pocketbook. Doni Rae Franklin and her family have managed to upcycle two yellow buses into greenhouses: a longer one that is stationary, and a shorter bus that’s still mobile so the family can drive their fresh produce to market. The roof on the longer bus, which was replaced with polyethylene plastic, creates the ideal environment for growing crops and plants. The family put the tin roof from the longer bus to good use by making planters to grow crops in. The shorter bus, with its original roof still on, is great for keeping frost off growing crops. “As I’ve been getting more and more into commercial gardening, I’ve realized that these greenhouses are the best way to achieve a reliable harvest, stopping things like frost and hail from taking a toll,” says Franklin. — aleteia.org 20 Maximum Yield
