Abstract:
Different proportions of tomato waste compost (TWC) were combined with peat moss and vermiculite as growth substrates used to evaluate the quality of seedlings of economic vegetables, including tomato, hot pepper, cucumber and summer squash. The seeding substrates used were: (T0), vermiculite: peat moss: TWC (4: 1: 0, by weight), 0% TWC; (T1), vermiculite: peat: TWC (4: 0.75: 0.25), 5% TWC; (T2), vermiculite: peat: TWC (4: 0.5: 0.5), 10% TWC; (T3), vermiculite: peat: TWC (4: 0.25: 0.75), 15% TWC; and (T4), vermiculite: peat: TWC (4: 0: 1), 20% TWC. The best seedling response was recorded in substrate mixtures supplemented with 5% and 10% TWC, which hastened seed germination and improved seedling morphology. Since vegetable seedlings produced with TWC-amended substrate were of higher quality, compared to those produced exclusively on peat substrate, we suggest that TWC may be used to replace partially peat-based substrate used for vegetable transplants production in nurseries.
