ABSTRACT

This study was aimed at evaluating the different concentrations of nitrogen for tomato seedling production (Lycopersicon esculentum Mill.), hybrid Loreto. Five concentrations of nitrogen were analyzed: 0, 4, 8, 12 and 16 mEq / L, using as a basis the Steiner nutrient solution. A pilot randomized block design was used with six replications and five treatments. Thirty-five days after sowing, the following variables were analyzed: seedling height, stem diameter, fresh stem weight, fresh leaf weight, leaf area, dry steam weight, dry leaf weight, dry root weight and total nitrogen content. An ANOVA analysis (p <0.05) with post-hoc Tukey test was performed to compare each treatment variables. The results showed that the increase in the concentration of nitrogen has a positive effect on organ growth. The treatment with the highest values in the morphological variables was 16 mEq / L, which shortened the production time of seedlings ready for transplant.
