| ABSTRACT The authors evaluated critical points of production stages of the industrial tomato, through physical and physico-chemical analyzes of U2006 hybrid fruits in the harvest, 2016. Fruits were evaluated in relation to raw material, temperature, fresh mass, pH, soluble solids (°Brix), firmness, titratable acidity and extravasation of electrolytes. Samples were collected in six steps: manual, mechanized, truck, arrival at industry, unloading and selection mat in two periods, morning and afternoon, totalizing 60 fruits for each step, and four replications. Fruits which waited for more than 10 hours in the yard generated an increase in serious defects (%), loss of fresh mass, discount on the amount paid for the load. The most critical stages of the... |

| ABSTRACT One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quantified and five plants with high zingiberene selected (RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503) and four with low zingiberene content (RVTZ 2011-079-417, RVTZ 2011-331-460, RVTZ... |

| The influence of different cover crops was evaluated over the agronomic performance of tomato hybrids for industrial processing, as well as its effect over soil chemical attributes. The experimental design was completely randomized, in a split plot scheme, with four replications. Main treatments (plots) were composed of winter cover crops (oat, hairy vetch, clover and radish) and of a fallow area (spontaneous vegetation). Subplots were composed of four processing tomato hybrids (AP529, AP533, Kátia and Sicílio). We evaluated the total production (TP), marketable production (CP), average mass of marketable fruits (AMCF) and number of marketable fruits (NCF). Chemical analysis of soil was done in two stages: one week preceding implantation of cover crops and... |

| The species Helicoverpa armigera is one of the most important polyphagous and widely distributed pests in the world. Its occurrence was recently reported on soybean and cotton, in the states of Goiás, Mato Grosso and Bahia, Brazil. Tomato is also host species of H. armigera, among the 200 registered, being one of the most important crops in the Espírito Santo state. The production of tomatoes is fully dedicated for fresh consumption and the damage caused by H. armigera in fruits make unfeasible marketing. Therefore, this study aimed to record the occurrence of H. armigera in tomato crop in the Espírito Santo state. From February 2012 to October 2013, insects were collected from tomato plants in some producing areas. After insect identification, by... |

| ABSTRACT: This study carried out agronomic evaluation and estimated the combining ability of tomato lines for the industrial segment, aiming to elect promising genotypes for breeding and to find simple hybrids with superior traits. Randomized-blocks design was used with 57 treatments (45 experimental hybrids, 10 lines and 2 checks treatments) with 3 replications. A complete diallel among 10 tomato lines for processing was used. Evaluated traits were: fruit total (YT) and commercial production (YC), pulp yield (YP), fruit average mass (MM) and total soluble solids content (TSS). Diallel crosses allowed synthesizing experimental hybrids with superior traits when compared to commercial hybrids. Non-additive effects prevailed over the expression of YT, YC, YP... |

| ABSTRACT The amount of water and fertilizers used in the production of vegetables, specifically tomatoes, is high. This study was carried out to determine water and fertilizers use efficiency in closed and open hydroponic systems for tomato production under greenhouse conditions. Two treatments with eight replications were assessed; each replication consisted of 67 pots with two plants each. One treatment was a closed hydroponic system (with nutrient solution recirculation), and the other was an open hydroponic system (with non-recirculating nutrient solution). We quantified the amounts of water and fertilizers applied, as well as the losses (drained nutrient solution), in the two treatments during the entire cycle of tomato. In the nutrient solution (NS)... |
