Growth and initial yield under four planting densities and two weed managing strategies of peach palm (Bactris gasipaes K.) for palm hearts.
Keywords:peach palm, Bactris gasipaes, palm hearts, crop, densities.
The Study was
conducted at Los Diamantes Experiment Station, located in
Guápiles, Costa Rica. Four planting densities of the spineless
variety “Diamantes 10” (5000, 6666, 10000 and 20000
plants/ha) and two weed management strategies (chemical
and physical) were compared. The parameters evaluated were
plant height, stem diameter, shoot number per plant, palm
heart units harvested, industrial yield and economic income.
Besides, the effect on growth of weed competition was
evaluated. Differences were observed among densities in
regard to plant height and shoot number/plant at the age 9
month safter planting, being higher when planted at 6666
plants/ha). The higher planting densities gave the higher
yields evaluated as number of stems harvested and number of
exportable boxes during the first four months harvesting
