影响棕榈油产量的因素很多，包括种植材料、环境（气候和土壤）以及栽培管理。环境占据着至关重要的地位，即使有最佳的栽培管理，也会影响作物的生产潜力。不利的气候条件，例如干旱，会导致缺水，这对作物生产力有影响。本文旨在比较研究水分亏缺对开花期的影响，即开花期的性别决定期（采收前29个月）和花败育期（采收前10个月）。这项研究是在印度尼西亚廖内省泥炭地上的油棕种植园进行的，其特征年降雨量为2000 mm/年。本研究采用简单回归分析法，对五年两个屋苑的面板数据进行分析。结果表明，增加100毫米的油棕榈泥炭地种植园水分亏缺的影响，在性别决定阶段的生产力下降6%。相比之下，在花败育阶段，生产力的下降更为显著，即7%。分析还表明，研究不足对束数的影响大于束重。
Various factors influence palm oil production, including planting material, environment (climate and soil), and cultivation management. The environment occupies a crucial position that can affect crop production potential even with optimal cultivation management. Unfavorable climatic conditions, for instance, drought, can cause water deficit, which has implications for crop productivity. This paper aims to get a comparative study for the effect of water deficit on the inflorescence period, namely the sex determination phase (29 months before harvesting) and floral abortion (10 months before harvesting). The research was carried out on oil palm plantations on peatland in Riau, Indonesia, with the characteristic annual rainfall of 2000 mm/ year. This study employs a simple regression analysis on panel data of five years and two estates for data analysis. The result highlights that the increase of a 100 mm water deficit on oil palm peatland plantation impacts the decrease in productivity by 6% in the sex determination phase. In contrast, in the floral abortion phase, the decline in productivity is more significant, namely 7%. The analysis also indicated that the research deficit had more impact on the bunch number than the bunch weight.
