The influence of organic fertilization of tomato seedlings for the unconventional crop system with perlite and peat substrate

The study was conducted within the research center Hortinvest Bucharest of the University of Agronomic Sciences and Veterinary Medicine of Bucharest. The main goal of this research was to identify the best variant of organic fertilizers for the production of tomato seedlings, suitable for establishing a soilless tomato crop, on matresses filled with different types of substrates (peat and perlite with grain of 2 mm). I have used the hybrid biological material Cindel F1. During the process of seedling production, we have observed the following: the percentage of emerged plants, the dynamic of seedling growth, the number of leafs, the parcel's diameter, the total mass of the seedling. After the research I noticed that, through the fertilisation of the seedlings with organic products, a higher percentage of tomato plant emergence has been obtained.
