Content and concentrations of absorbed micronutrients in tomatoes under protected cultivation
Keywords:Lycopersicon esculentum, fertirrigation, nutrition, vegetable
AbstractProduction under protected cultivation is a relatively new practice in Brazil, and the area planted to tomatoes in such an environment is increasing year by year. Along with this growth comes a lack of proper technical information regarding our present stand. This work evaluates the grade and the quantity of micronutrients absolved by the tomato plant in a protected environment. Fertilizers were applied via soil, leaves and fertirrigating, using the cultivar Lucia. The experiment was carried out in Piracicaba, SP, Brazil, from December/95 to March/96. A completely random design was used with three treatments and six replications. At the flowering stage, plants presented the following micronutrient concentrations in mg kg-1: 56.1 of B; 107.8 of Cu, 440.4 of Fe; 313.8 of Mn e 194.9 of Zn. For a yield of 10.2 kg m-2, plants extracted the following quantities of nutrient in g m-2: 0.0274 of B; 0.0826 of Cu; 0.1694 of Fe; 0.1702 of Mn e 0.1133 of Zn.
