In order to identify the assisted pollination period and the harvest cycle’s frequency of the OxG hybrid (Elaeis oleifera x Elaeis guineensis) Corpoica Elmira, four assisted pollination and harvest cycles were assesed with a completly randomized block design with four treatments, in order to obtain high amounts of oil concentration in the bunches. The assisted pollination and harvest cycles of 21-days produced 23.9% ...

Soil deterioration in the Valle del Cesar has generated a gradual reduction of livestock in their productive response to pastures. That effect has been more intense in areas managed under a grass monoculture. As an alternative, an integration of agricultural, forest, and livestock production systems is proposed as an strategy for improving both environment preservation and production. The purpose of this study was to ...
Harvest prediction and control in interspecific hybrid Elaeis oleifera x Elaeis guineensis at Colombian west area of palm production. I. Ripeness period determination in order to obtain high amounts of oil concentration at bunchesPredicción y control de la cosecha en el híbrido interespecífico Elaeis oleifera x Elaeis guineensis en la zona palmera occidental de Colombia I. I. Determinación del periodo de madurez para obtener racimos con alto contenido de aceite.

This study was carried out to identify the ripeness period in order to obtain high amounts of oil concentration in bunches of the OxG hybrid (Elaeis oleifera x Elaeis guineensis) Corpoica Elmira in the palm production region of Tumaco, Colombia. The highest period of oil concentration in bunches was obtained between 170 and 180 days after assisted pollination, within this range it's possible to harvest the largest ...
