Tomato transplants grown on mixtures suitable for organic production
2018
One of the main tasks for every certified organic vegetable producer is to grow healthy and well-developed transplants. The aim of this study was to examine different substrates designed for the production of organic tomato transplants. On the basis of preliminary experiments, seven substrates consisting of different parts of natural peat, vermicompost, shrub and tree leaves compost and zeolites were compared with standard commercial substrates using tomato (Solanum lycopersicum L.) transplants grown in pots. The data concerning plant height, number of leaves, fresh plant mass, appearance of flower buds were collected. The differences in the examined traits were not significant for the majority of substrates. The zeolite-based substrate with high peat and vermicompost content achieved the best results and its production for the market should be considered. Three zeolite-based substrates with high rates of vermicompost and compost should be used as a model for tomato transplants substrate preparation.
