Abstract

Abstract. Climate variability including drought, water deficit, and dry spell considerably affect oil palm growth and yield. This research was aimed to study agronomic performance of oil palm under periodic drought especially in year 2011-2015 in a private plantation in Lampung Province, Indonesia, that managed 4900 ha of oil palm plantation. An observation was conducted on June-September 2016 (a year after long drought 2015) to collect agronomic data of oil palm trees that randomly sampled. The oil palm block farms were purposively sampled representing young (3-8 years), teenage (9-13 years), mature (14-20 years), and old trees (21-24 years). We collected the secondary data from the company and Radin Intan Climate Station. The results showed that oil palm plantation in Lampung faced a periodic drought that effect growth and yield. In period year 2011-2015, there were 3-5 dry months consisted of water deficit of 190 mm (drought stadium I), 285-359 mm (drought stadium II), and 406 mm (drought stadium III) with maximum dry spell of 45-51 days (long drought) up to 126 days (extreme drought). Agronomic performance showed a low stand per hectare (SPH) which the highest decreasing model of SPH was y = -2.8649x + 150.99 (R2 = 0.89, x = trees age). The farms of old palm oil trees had low SPH. A year after long drought, old trees characterized by more broken leaf and less female flower indicating higher drought severity. Bunch production was not significantly different among age categories of oil palm trees. Keywords: Agronomic, drought, oil palm, SPH
