Among leachates from Vinatea-green showed highest inhibition with 50% suppression at 0.12 mg dry leaves/mL agar. Caffeine in analyzed by...

Blueberry production in the field faces several challenges, including competition from weeds and soil suitability. Different mulch types are widely used blueberry cultivation to control weeds, conserve moisture, mitigate erosion. However, comparative effects of loose compressed wood chips on fruit quality weed systems have not been studied. Many farmers use expensive imported peat moss as covers, while others apply organic mulches such or chaff, which can be easily washed away by runoff....
