“…At the end of development, B deficiency in castor bean caused loss of dominance due to the death of the apical bud, similar to this work. For Oliveira et al (2009), in study performed with tomato cultivation, the B was bit limiting in the initial phase of development, possibly by the low need of the nutrient that stage where the amount provided in the adaptation phase supplied the need for culture in this period, unlike the present study there was low B supply in the adaptation phase of physalis seedlings.…”

The physalis production has caused interest of producers, consumers and traders due to its easy growing, high nutritional value and economic value added. The objective of this study was to evaluate the growth and characterize the symptoms of macro and micronutrient deficiencies in physalis seedlings (Physalis peruviana L.). The seedlings were grown in complete nutrient solution and also in solutions with individual omissions of N,

“…The cherry tomato plants B starved had no onset of inflorescences and, consequently, there were no fruit bunches. The symptoms observed in cherry tomato plants differed from those observed in tomato of the salad group, since for the latter the B was little limiting in the vegetative phase (OLIVEIRA et al, 2009).…”

“…It may be possible that the Cu present as contaminant in the nutrient solution was sufficient to the plant growth, which is common for elements required by plants at very low concentrations (FONTES, 1985). In salad-type tomato, the minus Cu also did not promote evident symptoms of deficiency (OLIVEIRA et al, 2009).…”

“…However, its accumulation in the minus Fe treatment was higher in the leaves and lower in the stems and roots comparatively to the control (Table 3). In salad-type tomato, the minus Fe was the one that most affected the development of the plants (OLIVEIRA et al, 2009).…”

Tomato is one of the most popular vegetables, with high nutrient demand. The nutrient concentration can vary depending on the development phase, cultivation system, temperature, soil conditions, luminosity, relative humidity and management practices. The aim of this work was to characterize cherry tomato visual symptoms of deficiency, as well as the effect of nutritional restriction on the development and nutrient concentration of plants cultivated in nutrient solution. Plants of the cherry tomato, cultivar Sindy, were grown in green house. We have used eleven treatments, one control with complete nutrient solution and the other ten omitting respectively the nutrients nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron. The experiment was performed in randomized design with three repetitions. After 60 days, the plants were removed from the solutions and their main symptoms were photographed and described. The traits evaluated were: total dry matter yield, dry matter of leaves, dry matter of stems and dry matter of roots; number of leaves, number of inflorescences; number of fruits and root volume. The concentration and accumulation of nutrients: nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, zinc and iron in leaves, stems and roots were evaluated. Nutrient concentration and accumulation were influenced by the deficiencies imposed. The visual symptoms of deficiency that had appeared firstly were those of phosphorus, boron and iron, respectively. The omissions of the nutrients nitrogen, magnesium and boron were the ones that most compromised the dry matter production of the cherry tomato plants.
