From: Potato-onion intercropping enhances tomato yield and quality and modifies soil microbial diversity
Plant dry weight (a), fruit yield (b), blossom-end rot incidence (c), soluble protein (d), soluble sugar (e), VC (f), and lycopene (g) contents in tomato under monoculture (T) and tomato/potato-onion intercropping (TO) systems. Asterisks indicate significant differences between monoculture and intercropping treatments, as determined by a Student’s t-test (*P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001).
