Influencia de la concentración total de la solución nutritiva y su contenido de nitrógeno sobre las plantas de tomates cultivadas en hidroponía

Abstract

In the present paper, the total concentration of the nutritive solution and the relative concentration of the Nitrate ion in the nutritive solution have been studied. Three total concentrations each of 0.35, 0.37 and 1.05 ats. and two relative concentrations of Nitrogen each of 60 and 80% of the anions have been used. No significative diferences have been found in the treatments, but there are parcial productions, giving better results the solutions of 1.05 ats. and 80% of nitrogen.
