Fertilization Has No Influence on Growth and Flowering of Eustoma grandiflorum (Raf.) Shinners Grown as Cut Flower

The fertilization of Eustoma grandiflorum (Raf.) Shinners grown in container in ornamental plant production is oft en empirically based. Previous research shows that the application of chitosan or cultivation technique like nutrient film technique (NFT) improved the performance of the treated cultivars. In order to further improve our knowledge of plant requirements, we measured the growth and flowering of two Eustoma grandiflorum cultivars upon the application of liquid mineral fertilizer „Fertina P” in the 1.5 and 3% concentration. The addition of fertilizer which contains inorganic salts had no impact on the growth and flowering of two tested cultivars ′Flamenco Pecotee Blue′ and ′Mariachi Blue′
