The objective of this study was to assess the effect of companion plants as marigold (Tagetes patula L.),
basil (Ocimum basilicum L.), lettuce (Lactuca sativa L.) and white mustard (Sinapis alba L.) on (i) greenhouse
tomato yield and fruit quality; (ii) root-knot nematodes infestation and (iii) energy effectiveness of tomato
production. The experiment was carried out during three consecutive years (2011–2013) in an unheated
greenhouse. White mustard caused significant decrease in early and total yield of tomatoes as well as
decreased the average fruit weight. Marigold, basil and lettuce did not decrease significantly the tomato
productivity. Chemical parameters of tomato fruit quality, including antioxidants content, measured
twice in a harvest period, were positively affected by the intercrop systems in most cases. Although all
tested companion plants suppressed to some extent the development of Meloidogyne spp., the white
mustard and marigold were the most promising ones having effectiveness of 53.45% and 46.38% against
the root-knot nematode invasion. The control treatment had the highest energy intensity (1.43 MJ kg
−1
),
mostly due to the costs for manual weed control. The manual operations for weed control in intercropping
systems decreased three times. The lowest energy intensity (1.03 MJ kg
−1
) was established for marigold
as companion plant of tomato. Based on the obtained results white mustard and marigold could be
considered as most promising companion crops in greenhouse tomato production.
