Abstract
Bactris guineensis es una palmera silvestre con potencial productivo en la agroindustria. En la presente investigación se utilizaron en 100 plantas de B. guineensis con edades de 1 a 2 años despues de transplante a las cuales se sometieron a distintas dosis de fertilizante nitrogenado (50,100, 150 y 200 kg/ha) con el objetivo conocer la biometría de las plantas y hacer aportes al manejo del cultivo. Como resultado relevante se encontró que la cantidad de nitrógeno aplicado es inversamente proporcional al crecimiento y desarrollo de la palmera. Los mejores resultados se registraron a la dosis de 50kg/ha de Nitrógeno. En relación con el diámetro del tallo el fertilizante nitrogenado fue estimulado en pequeñas dosis (0-50 kg/ha) pero a 100 kg/ha se obtuvo una inhibición. En investigaciones de este tipo se debe considerar la utilización de bacterias fijadoras de nitrógeno (BFN) como una alternativa en fertilización.
Abstract Bactris guineensis is a wild palm with productive potential in agroindustry. In the present researching, 100 plants of B. guineensis with ages from 1 to 2 years after transplantation were treated to different doses of nitrogen (50,100, 150 and 200 kg/ha) to know the biometry of the plant and contributions to crop management. We found as relevant result that the amount of nitrogen applied is inversely proportional to the growth and development of the palm tree. The best results were registered at the dose of 50kg / ha of Nitrogen. Additionally, we found that stem diameter was stimulated by nitrogen in small doses (0-50 kg / ha), but at 100 kg / ha, it was inhibited. Works of this type, we must considered the use of nitrogen-fixing bacteria (BFN) as an alternative in fertilization.
