Production and Qualitative Aspects of Tomato Fruits under Leaf Fertilizer Applications with Resistance Bioinducers

Abstract

The tomato is one of the cultures of great interest to the global agribusiness, especially to meet the industrial demand, resulting in income and quality of life to the producer. Given the complexity of culture, new technologies and management strategies are necessary. Hence, this experiment was carried out with the objective of evaluating the productivity and qualitative aspects of tomato fruits under leaf fertilizer applications with resistance bioinducers. The experiment was conducted in the field in a completely randomized design. The treatments consisted of T1 = Control and T2 = Leaf fertilizer + resistance bioinducers, with four replications. Productive aspects and quality of fruits for the industry were evaluated, and these aspects expressed through the variables, number of fruits per plant, fruit weight per plant, fruit average weight, fruit weight yield, longitudinal and transversal diameter, mesocarp thickness and fruit shape, total soluble solids and hydrogenionic potential. The treatment with leaf fertilizers based on Ca, Mg, B, S, Fe, Mn, Mo and Zn together with yeast hydrolyzate and humic acid bioinducers promoted significant increases in tomato production and fruit size, not altering, however, the qualitative aspects of these.
