FP associated positively with HT and ABW. RL showed negative correlation with FP across all planting densities but generally has no association with FFB and O/B. In this trial Density 2 148 palms/ha was the ideal planting density for maximum FFB and oil yield 6.0 t/ha/yr per unit land area on inland soil and has been the standard practice of the oil palm industry.

Abstract

A planting density trial on 15 dura x pisifera DxP bi-parental crosses from six Malaysian seed producers agency was laid down in Bungor series soil in 1983 at the Malaysian Palm Oil Board MPOB Ulu Paka Research Station Terengganu Malaysia. The palms were planted in equilateral triangle in four planting densities namely 120 D1 148 D2 Control 170 D3 and 215 D4 palms/ha. Data on fresh fruit bunch FFB bunch number BNO bunch weight ABW fruit/bunch F/B oil/bunch O/B frond production FP rachis length RL and palm height HT were collected from 1987 to 2005. Analysis of variance ANOVA of pooled data over years and densities showed significant differences among progenies G and agencies A for all traits reflecting their varying genetic backgrounds. Variations in planting densities D were significant for ABW F/B and FP. Statistical differences were detected in GxD interactions for ABW RL and FP and AxD interaction for ABW. FFB yield among agencies ranged from 18.4 to 21.5 t/ha/yr highest in Agency A2 attributed to high BNO. O/B varied from 25.9 to 28.2; the latter observed in Agency A1. HT of the 20-year old palms pooled over densities ranged from 8.99m Agency A1 to 10.02m Agency A5 with the height increment HI among agencies between 50cm/year and 56cm/year. Variation for HT among densities was between 8.70m D1 and 10.43m D4 with HI between 48.3cm/year and 58cm/year. FP ranged from 17.1 D4 to 19.1 D1 fronds/yr while RL between 6.20 D1 to 6.86m D4. Density D2 Control recorded the highest FFB 21.7 t/ha/yr followed by D3 20.9 t/ha/yr D4 19.2 t/ha/yr and D1 18.6 t/ha/yr. Generally HT was significantly and positively correlated with FFB components. FP associated positively with HT and ABW. RL showed negative correlation with FP across all planting densities but generally has no association with FFB and O/B. In this trial Density 2 148 palms/ha was the ideal planting density for maximum FFB and oil yield 6.0 t/ha/yr per unit land area on inland soil and has been the standard practice of the oil palm industry.
