Resumen:
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.
