“…PC max was close to 52 DAT for Crossed and Vertical Fence systems, and at 58 DAT for the Viçosa systems (Figure 3b). The PC max values obtained for IAF are in agreement with those obtained by Fayad et al (2001) in the same location as in this study, who observed maximum IAF at 58 days, reaching the end of the cycle at 0.17, which the authors attributed to the period of senescence and foliar abscission. The extension of the second phase for the IAF delayed the onset of senescence and foliar abscission of the tomatoes cultivated in the Viçosa system in comparison to the other cultivation systems, a fact that would explain, at 75 DAT, the highest IAF for the tomatoes cultivated in the Viçosa system.…”

The objective of this work was to analyze the growth of the Upiã tomato cultivar in the Vertical, Crossed Fence and Viçosa cultivation systems, in order to obtain explanations for the productive gains achieved in the Viçosa system. The experiment was conducted in Viçosa, Minas Gerais State, Brazil, from August 21st to December 5th, 2012, in the scheme of subdivided plots, being the plots represented by the cultivation systems: Vertical, using tape, 1.0×0.5 m spacing; Crossed Fence, staked with bamboo, 1.0x0.5 m spacing; and Viçosa, using tape, 2.0x0.2 m spacing. The subplots were composed by the sampling times of the plants: 15, 30, 45, 60 and 75 days after transplanting. The experimental design was in randomized blocks, with four replications. Each plot was composed by three lines of 10 plants, making a total of 30 plants per plot, being evaluated the four central plants of each plot. We evaluated the dry matter of leaves (MSF), stem (MSC), inflorescences (MSI), fruits (MSFr) and total (MST). Using the foliar area index, measured by digital scanners and the previously obtained dry masses, we determined the physiological growth indices: foliar area index (IAF), specific foliar area (AFE), relative growth rate (TCR), and net assimilation rate (TAL). The Viçosa system altered the growth pattern of the tomato, quantified by the growth analysis, in comparison to Crossed and Vertical Fences. The prolongation of the second growth phase for the dry matter of fruits could possibly explain the productive gains obtained in the Viçosa system. Additional studies are required in order to clarify the relationship between the duration of the second phase of fruit dry matter growth, the physiological indexes AFE, IAF and TAL with the size and fruit yield of the tomato.

“…Alguns trabalhos têm mostrado a importância do conhecimento acerca do crescimento e índices fisiológicos, bem como a influência de fatores externos sobre a produção final da planta (Peluzio et al, 1999;Fayad et al, 2001;Andriolo et al, 2004), entretanto não são comuns os estudos relacionados a este tema envolvendo a utilização de cobertura do solo no cultivo do tomate.…”

Growth analysis of tomato plants 'SM-16' cultivated under different mulchingIn order to evaluate the growth of tomato plants cv. SM-16, grown under different mulching, a trial was carried out at WG Fruticultura, Baraúna, Rio Grande do Norte state, Brazil, between July and November 2008. The experimental design was arranged in splitplots, under completely randomized blocks with four replications. Treatments (plots) were the mulching types: uncovered soil, black polyethylene film, silver polyethylene film, white polyethylene film and black polypropylene TNT, and the splitplots were sampling times: 14, 28, 42, 56, 70, 84 and 98 days after transplanting (DAT). Dry mass accumulation in leaves (AMSF), branches (AMSR), inflorescences (AMSI), fruits (AMSFR) and total (AMST), leaf area index (IAF), leaf area ratio (RAF), specific leaf area (AFE), absolute growth rate (TCA), relative growth rate (TCR) and net assimilation rate (TAL) were determined. The mulching influenced the development of dry matter accumulation in leaves, branches and fruits, and the TNT promoted the highest averages. The fruits behaved as the preferential drain of the plant. The TNT was the mulching that has promoted the highest average for the leaf area index and absolute and relative growth rates. The leaf area ratio, specific leaf area and net assimilation rate were not influenced by cover crops.

“…Os teores de Mg, Cu, Zn e Fe observados estão dentro da faixa considerada adequada, o N ficou abaixo dessa faixa e o P, K, S, Ca, Mn e B se encontram acima, considerando-se os valores de referência citados por Reuter & Robinson (1988). Fayad (1998) encontrou na matéria seca de folhas do tomateiro, no início da colheita, os valores de 3,8; 0,3; 2,9; 5,3; 0,8; e 1,6 dag kg -1 para N, P, K, Ca, Mg e S, respectivamente, e 175; 543; 323; e 1.282 mg kg -1 para Zn, Fe, Cu e Mn, respectivamente.…”

Productivity, fruit quality and nutritional status of single truss long shelf life tomato, cultivated in hydroponic system, with different nutrient sources There were evaluated the yield, fruit quality and nutritional status of single truss and long shelf life tomato, cultivated in nutritive solutions prepared with different nutrient sources. The experiment was carried out from 04/05/99 to 13/09/99 in a greenhouse of the Universidade Federal de Viçosa, Brazil. Two groups of nutrient sources were tested to prepare the solutions for vegetative growth and two groups for the frutification solutions. The combinations of those groups gave rise to four treatments, disposed in the randomized blocks design with eight repetitions. Seedlings of the F 1 hybrid Carmen 36-day old were placed in 8,6 L vases, spaced 0.35 x 0.70 m. The yield, fruit quality and nutritional status of the plants were evaluated, as well as the partition of Ca, Mg and K in the fruit. The data were submitted to analysis of variance and the means were discriminated using Tukey at 5% of probability. There were no significant differences among treatments. The average yield per plant was of 920 g, with an average plant cycle of 96 days, corresponding to a yield of 142 t ha -1 year -1 . The concentrations of N, P, K, Ca, Mg and S in leaves were, respectively, 3.18; 1.25; 5.11; 4.50; 0.88; and 1.79 dag kg -1 , and concentrations of Fe, Zn, Cu, Mn and B were, respectively, 209; 96; 10; 665; and 209 mg kg -1 . In the fruit, Ca and K were presented in larger concentration in the proximal area, unlike Mg, that was present only in lower concentration in that portion.
