MEJIA DE TAFUR, M. Sara; ESTRADA S, Edgar I  and  FRANCO P, M. Margarita. Response of tomato to different concentrations of nutrients. Acta Agron. [online]. 2007, vol.56, n.2, pp.75-83. ISSN 0120-2812.

In the greenhouse of the Universidad Nacional de Colombia at Palmira branch an experiment to determine the nutritional requirements of tomato UNAPAL Maravilla under hidroponic system, using reactive degree salts and distilled water was carried out. The data demonstrated that the suitable stage of development to determine the nutricional requirements is 47 days after planting, since the plants are in preflowering, shortly before beginning the linear phase of growth. The nutritionale requirement of tomato is: N, 13 - 20 mM ; P, 1 - 1,5 mM ; K, 5 - 8 mM ; Ca, 4 - 6 mM ; and Mg, 2 - 4 mM .

Keywords : Lycopersicon esculentum Mill; Tomato; nutritional requirement.
