“…The economic potential of these production units under organic system can be increased, since the use of tomato cultivars improved genetically expresses 3x production potential when compared with the ones obtained in this study (non-hybrid cultivar) and the increase in cultivated area does not represent a proportional increase in investment costs. Nevertheless, since this is a differentiated product in the market, selling price of the product must be estimated taking into account this factor, as according to Carvalho et al (2014) price paid is what presents the greater sensitivity of the profitability of tomato crop.…”

Financial profitability is a factor as important as quantifying production using new technologies. This study was installed to evaluate short and long term financial viability of organic production of cherry tomatoes. Plants were grown in a greenhouse under diverse technological degrees for partial control of micrometeorological elements. The experiment was carried out at the experimental field FEAGRI/UNICAMP in three greenhouses with automated mechanical ventilation systems, evaporative cooling and thermo reflective screen. We cultivated Carolina cultivar in a spacing of 0.5x0.9 m, each plant conducted with two stems, under organic production and fertilization management. The average of production data of treatments {three greenhouses (A= climate-controlled, B= mobile screen and C= fixed screen), two cultivation systems (pots and soil beds) and five biofertilizer doses (0, 50, 100, 150, and 200%)} were evaluated using joint analysis. Thus, the economic indicators {cost benefit ratio (B/C), net present value (NPV), internal rate of return (IRR) and Payback (PV)} were evaluated through revenues and production costs. The best alternative to net monthly cycle profitability (500 m2) was approximately 1 and 1.5 minimum wage with and without particular labor, respectively, associated with the greenhouse of medium technological level, using soil bed cultivation system. The economic viability of the project in long-term interest rates above 3% (a.a) was consistent, but the payback period even with a rate of 1% a.a was high (6.54 years) in financing conditions.

“…Brazilian tomato production in 2017 was estimated at 4.5 million tons of fruit (IBGE, 2018). In addition to the nutritional and economic aspects, the culture has a social relevance due to the generation of employment and being a source of income for several families (PEIXOTO et al, 2017;PRAMANIK;MOHAPATRA, 2017), which strengthens family farming, reducing rural exodus and promotes regional development (CARVALHO et al, 2014).…”

Productivity and quality of bagging fruit of hybrid tomatoes

et al. 2020

View full text Add to dashboard Cite

Tomato cultivation is challenging due to the high susceptibility to various pests and diseases. Fruit borer insects make fruits unfeasible for commercialization because this favors colonization by pathogens. The loss due to borers can be avoided by bagging the bunches of fruit, helping the conventional crop to be more sustainable, reduce the use of pesticides, reduce the residue in fruits and improve the quality of life of rural workers, by less exposure to agrochemicals and poisoning problems. The results are products of better quality and with the possibility of better profitability. The objective of this study was to evaluate the efficiency of tomato bagging in the control of fruit borer insects, and its effects on lycopene content, taste, productivity and profitability. The experiment was conducted in a field in the municipality of Uberaba-MG, from November 2016 to September 2017. The experimental design was a randomized block design, in a 3 x 5 factorial, with four replications. The factors consisted of three tomato hybrids: Dominador (salad), Ravena (Italian) and Carina Star (Santa Cruz), and fruit bagging types, made by TNW (tissue-non-woven), tulle, organza, brown craft and a control, without fruit bagging. The decision of bagging use depends on the pest incidence in the area and the change in the agronomic characteristics of the tomato. The organza and tulle fruits bagging reduce the incidence of borer insects, relative to the control, in the cultivation in spring-summer. The Dominador presents higher brix content among the evaluated hybrids. Carina Star, when bagged with organza, produces fruits with higher levels of lycopene, and is 116% superior to the other cultivars. From the second harvest, organza fabric is the most profitable bagging, since it is the only one that can be reused several times and is therefore more sustainable.

“…The largest producer is the state of Goiás with a production of 1,262,701 tons, followed by São Paulo with 938,800 tons, the state of Paraná is in the fifth position with 260,643 tons (IBGE, 2018). In the present scenario of horticulture, tomato cultivation has great economic and social relevance, since this activity produces food, generates employment and income, strengthens family agriculture, reduces rural exodus, and promotes regional development (Carvalho et al, 2014). Tomato cultivation shows high employment in the industry for the formation of sauces, juices, dehydrated pulp (Filgueira, 2008), besides being consumed "in natura".…”

The use of plant growth-promoting bacteria (PGPB) may be a promising agronomic practice to improve the growth and productivity of vegetables. The objective of this work was to evaluate the effect of inoculation of Azospirillum brasilense on plant growth and tomato fruit production. Two experiments were carried out: the first one evaluating the growth of the plants in a greenhouse and the second one evaluating the production of fruits under field conditions. The experimental design used in two experiments was the completely randomized 2 x 5 factorial scheme, with four replications. The treatments resulted from the combination of two tomato cultivars (Gaúcho Melhorado and San Marzano) and four inoculant doses (0; 2; 4; 6 e 8 mL kg-1 of seed) containing the Ab-V5 and Ab-V6 strains of A. Brasilense. The application of inoculant containing A. brasilense improved the growth and dry matter production of tomato cultivars Gaúcho Melhorado and San Marzano. The highest values of plant height, stem diameter, root length, root volume, relative chlorophyll content and dry matter of shoots and roots are obtained with the dose of 4 to 6 mL kg-1 of inoculant, allowing to infer that the maximization of plant growth and the production of tomato fruits with the application of inoculant containing Azospirillum brasilense can be obtained with the use of approximately 5.0 mL kg-1 of seeds for tomato cultivars.
