Some scientific reports support the idea of using plant interactions to promote the growth
and yielding of vegetable crops. The plant interactions in vegetable production under intercropping
conditions were investigated in ERDF funded project ‘Elaboration of environment-friendly crop
growing technologies identified by the Green Deal and their implementation in horticultural
production in Latvia (GreenHort)’ implemented in Latvia Institute of Horticulture with the aim
to introduce strip cropping in the vegetable production. The investigations were carried out at the
Institute of Horticulture, Latvia (57°03’44.6’’N, 22°54’53.2’’E), during the growing seasons of
2021 and 2022. The vegetable crops (carrots, cabbage, onions, and pumpkins) were grown in
intercropping with agroecological service plants or aromatic plants as companion plants (white
clover, marigolds, tagetes, lavender, sage, coriander). The investigated variants were compared with
the control, where vegetable crops were grown in monoculture as usual. Each intercrop variant
consists of 7 alternating rows (each 0.6 m wide) - 4 rows of service crop and 3 rows of vegetable.
There was observed significant influence of the growing system on the plants productivity. The
sharpest differences between variants were observed for cabbage - marigold, sage and lavender
had a positive influence on the cabbage yield formation, but white clover had an extremely
negative influence on the cabbage plant growth. White clover had a negative influence also on
carrot and pumpkin productivity. Sage had a yield-promoting influence on the carrot crop. There
was not found any significant influence of the agroecologial crops on onion productivity.
