The influence of different types of ecological fertilizers on the agroproductive capacity offive tomato cultivars

Abstract

The purpose of this paper is to evaluate the influence of the application of fertilizers allowed in organic farming to an assortment of autumn tomatoes. The research was conducted in the didactic and experimental field of the Vegetable growing discipline, at U.S.A.M.V. Iaşi. The experiment was of a bifactorial type, testingthe influence of the cultivar with five graduations (Perra D`Abruzzo, Firmus F1, Raluca; Bilbo F1 and Rio Grande) and of the fertilization with three graduations (unfertilized, organic fertilization with Humic and the application of a product based on microorganisms, namely Micoseeds MB) underthe conditions of the cropyear 2019. The cropwas established by seedlingsof 45 days, in strips of two rows, the distance betweenthe strips being 90 cm, and between rows,of 50 cm. The distance between plants in arow was 25 cm, resulting in a density of about 57 thousand plants per hectare. The results obtained demonstrate the efficiency of the products used, the yields obtained in the case of fertilized variants being higher compared to the non-fertilized variant, for all five cultivarsused.
