From: Potato-onion intercropping enhances tomato yield and quality and modifies soil microbial diversity
Alpha diversity of bacteria (a) and fungi (b). (T) tomato monoculture, (TO) tomato/potato-onion intercropping. Values are mean ± standard deviation. Asterisks indicate significant differences between monoculture and intercropping treatments, as determined by a Student’s t-test (*P < 0.05; **P < 0.01).
