Abstract
Abstract The field trial was carried out in 2016 and 2017 on the grounds of the Botanical Garden of the Slovak University of Agriculture in Nitra. The aim of the paper was to test the impact of new organic fertilizers from Company Rokosan on the yield parameters and the morphological and phenological properties of tomatoes. In the experiments, we observed two determinant varieties, namely ‘Brixol F1’ and ‘Uno Rosso F1’. We used the bulk organic fertilizer Rokosan P, designed for fruiting vegetables, and the liquid fertilizer Rokohumin Z. Both forms of fertilizers are produced as organic biomineral fertilizers, their main ingredient being keratin. They contain 9% N, 9% P 2 O 5 , 9% K 2 O, 3% MgO and trace elements. The total harvest in the control variant without fertilization was the lowest compared to the fertilized variants. The second variant was fertilized with the Rokosan P fertilizer, and the harvests were in both years and in both varieties higher than in the variant 1. The third variant was fertilized with the Rokohumin Z, the liquid fertilizer and achieved the best crop yields per plant. For the ‘Uno Rosso F1’ the best total harvest weight was 7.2 kg per plant in 2016 and 8.96 in 2017. For the ‘Brixol F1’, the highest harvest was 8.14 kg per plant in 2016 and 9.24 kg in 2017. In terms of yields and the number of fruits, combined fertilization with the bulk fertilizer Rokosan P and the liquid fertilizer Rokohumin Z reached the second highest values.
