“…The market demand for fresh tomatoes with enhanced taste and cooking versatility has expanded the cultivation of saladette/roma tomato plants ( Shirahige et al, 2010 ). However, high production costs, along with the strong susceptibility of the crop to various types of biotic and abiotic stresses have driven the search for alternative, more feasible growth varieties for producers ( Wamser et al, 2012 , Almeida et al, 2015 ).…”

“…Silva et al (2013), evaluating the fertigation of tomatoes in a protected environment, observed that the excessive fertilization caused a reduction in the number of fruits obtained per plant. Likewise, Almeida et al (2015), evaluating conduction systems, observed a yield ranging from 48.22 t ha -1 (10,000 plants per hectare) and 109.58 t ha -1 (25,000 plants per hectare), thus demonstrating that there is a great variation in yields between different cultivation systems for the tomato culture.…”

“…The difference in yields, comparing the Distrito Federal regions with other Brazilian regions, could be related to the tomato cultivation during the winter, in addition to different types of plant conduction systems (Melo and Vilela 2005). Almeida et al (2015), analyzing agronomic characteristics in the cultivation of hybrid tomatoes, in different conduction systems, obtained an estimated yield of 74.65 t ha -1 for tomato plants grown with just one stem. In this study, tomato plants grown with only one stem showed a higher estimated yield, 106 t ha -1 (Table 3).…”

Looking to reduce the cost and maximize tomato productivity, this study aimed to evaluate fertilizer doses and conduction systems. For this, a field experiment was carried out in randomized blocks, in a simple factorial scheme, which consists in four fertilizer doses, (50, 100, 150 and 200% dose), and four conduction systems (with one or two plants per pit, and one or two stems per plant). Plants were spaced 0.44m and 1.5m between lines. Each plot consisted of 10 plants. The evaluated characteristics were fruit mass, number of fruits, total production per plant and pit, longitudinal and transversal dimension of the fruit. Under the experiment conditions, interactions were observed between fertilization and conduction only for the transversal and longitudinal diameter. The C4 conduction system showed superior results for the estimated yield when compared to the treatments containing only one plant per pit (C1 and C2). For the fertilizer doses, the observed yield was 142.68 t ha -1, in the 150% dose, and 114.84 t ha -1 for the 50% dose. The highest production per pit was obtained in the 150% fertilizer dose and the C4 conduction, but this treatment showed a lower average fruit mass. The treatment with two plants per pit and two stems provided lower fruit average mass than the treatments containing a single plant. The fertilization influenced only in the longitudinal diameter, and the largest diameter was observed in the recommended fertilization dose. Aiming at cost/efficiency relation, the 100% dose and the C3 were considered the best treatments.

“…The Viçosa cultivation system and its adaptations provided promising results and are very well accepted in the horticultural community for providing greater insulation and aeration to plants. Moreover, it markedly reduces the incidence of phytopathogens in the culture, which is crucial in reducing the volume of pesticides applied to tomato crops, and the problems of their residual effect, while providing greater productivity and profitability (Almeida et al, 2015).…”

Tomatoes play an important nutritional role due to the chemical-nutritional composition of this fruit, and its common use in dishes and food products. Its fruits provide pronounced antioxidant properties to the human diet, because of the presence of vitamin C, carotenogenic compounds such as lycopene and β-carotene, and phytochemicals such as flavonoids. Despite this, the antioxidant function and carotenoid levels in tomato may present significant differences depending on the system of cultivation, growing season, and environment in which this vegetable is cultivated. In light of this, this study aimed to assess the effects of the cultivation system known as “Viçosa”, in relation to traditional tomato cultivation systems, over two seasons. This assessment was done both under field conditions and in a controlled environment. The nutritional aspects of the fruits, such as the levels of phenolic compounds, lycopene, beta-carotene, and antioxidant activity, were analyzed. The controlled environment in the autumn-winter season, associated with the Viçosa cultivation system, facilitated increases in the lycopene content. Furthermore, field cultivation provided an increase of 68% and 38% in the total phenolic concentration in tomato fruits, in the spring-summer and autumn-winter seasons, respectively. Field cultivation also provided an increase of 31% in the antioxidant activity of the fruits, compared with that of the controlled cultivation, in the autumn-winter season. The increase in the levels of total phenolics and antioxidant activity of fruits due to cultivation in the field represents an advantage as cultivation in this environment has a lower cost than cultivation in a controlled environment. The cultivation systems did not influence the chemical-nutritional aspects of fruits; moreover, the Viçosa system brings together aspects such as high productivity and profitability, without compromising the chemical-nutritional aspects of the fruits, thereby configuring a promising system for tomato production.
