Treated palms averaged 8.9 cm taller and 2.5 cm greater in stem diameter than the untreated control.

Weekly measurements were conducted on KPCB-treated Millennium oil palms and an untreated control of the same cultivar. Across the reported trial observations, treated plants averaged 8.9 cm greater in height and 2.5 cm greater in stem diameter.

The supplied source provides the average difference between treated and untreated palms but does not provide the raw average height or stem-diameter values for either group. For that reason, percentage increases cannot be calculated. Leaf blade area was measured weekly, but no numerical leaf-area result is supplied. José Efrén Fajardo is reported as describing the KPCB-treated palms as higher quality than the control, but the source does not define a numerical crop-quality score. It also states that the results were well above what SENA typically observes in trials without KPCB, but no historical SENA benchmark values are provided. Despite the older case-study title referring to improved fruit quality, no fruit production, bunch weight, fruit number, oil extraction, yield, or fruit-quality measurements are supplied. This case is therefore presented as a nursery plant-growth comparison rather than a fruit-quality or yield case.

Why this matters for oil palm growers: This SENA nursery trial provides direct growth differences between treated and untreated Millennium oil palms of the same cultivar. The KPCB-treated palms averaged 8.9 cm taller and 2.5 cm greater in stem diameter, documenting measurable differences in early-stage plant development.
