“Evaluación de la fertilización química y orgánica en maíz (zea mays) en el cantón La Maná”.

In the investigative work entitled "Evaluation of chemical and organic fertilization in corn (Zea mays) in the La Maná canton, the objective was to compare the yield reached by corn in the choclo state when both fertilization variants are applied in the corn crop. The investigation was carried out using a completely randomized block design (DCBA) with four treatments (one control, one chemical and two organic) and five repetitions. Variables of great importance for crop yield were evaluated, such as plant height and load, number of leaves, ear length, ear diameter and ear weight per plant, which served to obtain yield per plant. hectare. The best results in these variables with the application of organic and inorganic fertilization showed the highest value for the treatment with nitrogen fertilization (T1), with significant differences with respect to the rest, in number of leaves 8.11, ear insertion 104.6 cm, diameter ear of 4.10 cm and a yield of 12022.2 kg/ha, however, the second best result was shown by the inclusion of poultry manure as fertilizer, with higher plant height values of 198.80 cm and a yield of 11400 kg/ha/ ha, which highlights the importance of applying organic fertilization in species such as corn. On the other hand, the control or control did not differ from T3, with the two remaining treatments. While in the cost-benefit analysis, chemical fertilization was similar, in which producing with NPK implies an expense of $17.50 and a profit of $42.50 of net benefit.
