Hibrit domates fidelerinin (Lycopersicon esculentum L.) vejetatif gelişimi için hümik maddelerin uygulaması

Abstract

It is known that the use of resistant cultivars and mineral nutrition associated with humic substances, such as humic and fulvic acids, can favor plant development, promoting aerial parts and roots growth, being a viable technique for better vegetative development of plants in general, and, consequently, for better final productivity. The aim of this work was to evaluate the effect of the fertilizer Bio Humate®, based on humic substances, in the vegetative development of Justyne® hybrid tomatoes. The experiment was conducted in greenhouses of University of Tuiuti do Paraná/Brazil with a completely randomized experimental design, arranged in a 4 x 2 factorial scheme with three doses of the commercial product’s application (1.5, 2, and 2.5 mL L-1 of Bio Humate®) on three repetitions Justyne® hybrid tomato seedlings that were subjected to samplings at 42nd and 56th days after transplanting (DAT)). The treatments were applied every 14 days, starting at 7 DAT at 42 and 56 DAT. The soil application of the Bio Humate® fertilizer showed better results at 2 mL L-1 of doses for the biometric and biochemical parameters evaluated in the vegetative development of Justyne® hybrid tomatoes, even though the chlorophyll content at 56 DAT is the lowest.
