Resumen

There is a growing interest in developing ecological agriculture in order to achieve cleaner production and pollution reduction related to the use of chemical fertilizers. The present research goal is to compare the effects of chemical fertilizer such as urea, in comparison to biofertilizer based on bacterium Azotobacter sp, on the growth of cowpea bean (Vigna unguiculata L. Walp). For this purpose, the germination and subsequent growth of the bean plants were carried out during the month of March, in a greenhouse with a controlled environment. It was demonstrated that the optimal dosage was 1,9x109 total cells contained in 1 ml of biofertilizer Azotobacter sp getting an average length of aerial part (LAP) of 16,333 ± 0,757 cm. While with urea, we have obtained length values of aerial part of 14,267 ± 0,850; 15,767 ± 0,987; 15,567 ± 1,041 cm for volumes of dosification of 1, 2 y 3 mL respectively. A control test without fertilizers was carried out for comparison. In conclusion, the replacement of urea with the biofertilizer Azotobacter sp. is feasible, being a viable alternative to reduce soil and environmental pollution.
