Yield of tomato 'Debora Pto' under organic-mineral fertilization via foliar and drip irrigation

Yield of tomato 'Debora Pto' under organic-mineral fertilization via foliar and drip irrigation The tomato ranks second in economic importance among the vegetables in Brazil. To increase the productivity, technologies are currently used as the foliar application of the organic-mineral fertilizer and fertigation, which aims at stimulating and improving the root system development and, at the same time, is a balanced source of nutrients for plants. The objective of this work was to evaluate the agronomic efficiency of commercial liquid organic-mineral products applied to the leaf and through fertigation and its effects on fruit yield and quality of tomato hybrid Debora Pto. The experiment was carried out in Uberlandia, Minas Gerais State, Brazil, in the entirely randomized experimental design with three treatments and eight replications. The treatments were: Control; Treatment 1: drip irrigation of Aminoagro raiz 0.5 L ha(-1) after transplanting and foliar application of Aminoagro folha top 0.2 L ha(-1), Aminoagro fosfito 0.2 L ha(-1), Aminoagro energy 0.5 L ha(-1) and Aminoagro fruto 0.2 L ha(-1) and Aminoagro mol 1 L ha(-1), started at transplanting; Treatment 2: foliar fertilizer with Aminoagro raiz 0.5 L ha(-1) after transplanting; Aminoagro folha top 1 L ha(-1); Aminoagro energy 2 L ha(-1) with the Aminoagro folha top; Aminoagro mol 2 L ha(-1) and 3 L ha(-1), Aminoagro fosfito 1 L ha(-1) and Aminoagro fruto 1 L ha(-1). The evaluated variables were: the production of fruits according to their classification by size into the groups 2A, 1A and discarded fruits. The results showed that from the third week on, the treatments 1 and 2 presented higher production of tomato extra type 2A. The same occurred for the total commercial production. Total production was significantly higher in treatments 1 and 2, which received organic-mineral fertilizers and the income generated by those treatments was superior to the control treatment.
