Abstract

In order to find out the concentration of macro and micronutrients, as well, the total amounts of nutrients absorved by Solanum gilo, var. Morro Grande Oblongo, plants were collected from field from 30 days up to 180 days and analysed for the elements. At the flowering stage the leaves presented the following concentration: N-0.55%; P-0.30%; K-2.00%; Ca-1.21%; Mg-0.22%; S-0,27%; B-50 ppm; Cu-11 ppm; Fe-774 ppm; Mn-69 ppm; Mo-0.5 ppm; Zn-22 ppm. A production of 9 M.T./ha. effective harvested content: N-26 kg.; P-4 kg.; K-24 kg.; Ca-5 kg.; Mg-2 kg.; S-2 kg.; B-25 gr.; Cu-17 gr.; Fe-89 gr.- Mn-37 gr.; Mo-0.8 gr.; Zn-34 gr..
