“…The dry matter yield was obtained by oven drying the seedlings at 85ºC for 48 to 72 hours until a constant weight was obtained. Transplantable seedlings were healthy plants without any growth abnormalities with at least 10 to 12 green leaves and with a minimal girth of 15 cm and above (Ugbah, 2008).…”

“…The use of this inorganic fertilizer NPKMg 12:12:17:2 has been limited by scarcity, rising cost, low quality and unavailability during the period of peak demand (Ugbah, 2008). Other limitations of the use of inorganic fertilizers are the declined in soil organic matter content, soil acidification as a result of the residual effects, as well as degradation of certain soil physical properties with resultant increased incidence of soil erosion (Goh and Hardter, 2003).…”

Impact of newly introduced liquid fertilizers on growth and development on oil palm seedlings was investigated at the Nigerian Institute for Oil Palm Research Main Nursery, Benin City for two cropping seasons 2013 and 2014 respectively. The fertilizers investigated are Operon 22:0:0, Advantage 20:20:10, Boost Xtra 20:20:20 and conventional fertilizer NPKMg 12:12:17:2. The trial consists of 9 treatments laid down in Randomized Complete Blocks Design (RCBD) in three replicates at zero application (control), 28 g, and 56g per seedling respectively. Treatments were applied at 3, 5 and 8 months after planting and data were collected on seedling height, girth, number of frond production, dry matter yield and percentage of transplantable seedlings at 3, 6 and 12 months after planting. Data collected were analysed using analysis of variance (ANOVA) and their mean compared with Turkey’s Honest Significance Difference (THSD) at 5% level of probability. At 3 and 6 months after planting, seedlings treatments had no significant effects on palm height, girth and number of frond production. However, at 9 and 12 months after planting, applied treatments had significant effects on palm height, girth, dry matter yield and the number of transplantable seedlings. The highest palm height (138.5 cm), girth (23.5cm), number of frond production (12), transplantable percentage (97.7%) and dry matter yield (198.5.7 g) were obtained in seedlings that received application of 28 g NPKMg 12:12:17:2, while the least palm height (75.5 cm), number of frond production (11), transplantable percentage (68%) and dry matter yield (105.8 g) was obtained from the control. The performance of seedlings that received fertilizers were all significantly different from the control, this is an indication that the liquid fertilizers Operon 22:0:0, Advantage 20:20:10 and Boost Xtra 20:20:20 could be used as an alternate fertilizer for raising oil palm seedlings when the conventional NPKMg is not readily available.

“…The application of organic materials influences the degree of aggregation and aggregate stability and can reduce bulk density, increase porosities, water holding capacity, moisture retention and transmission, and drought resistance in plant (Cheng et al, 1988). Preliminary fertilizer trials for potted nursery experiments indicated that 28g to 42g NPKMg (12:12:17:2) applied at two or three equal doses seemed adequate for optimum oil palm seedling production (Onwubuya, 1982;Ugbah, 2008). Similarly, Aisueni et al (2000) reported that composted oil palm bunch waste when applied at 150g per polybag enhanced nursery seedlings production.…”

A greenhouse study was conducted at the University of Nigeria, Nsukka to compare the effects of sole and integrated use of composted oil palm bunch waste and chemical fertilizer for improving the growth of oil palm seedlings under water stress condition. The experiment was a 3x3x4 factorial in a completely randomized design with three replications, comprising 3 factors thus irrigation intervals, NPKMg compound fertilizer and composted oil palm bunch waste. Water stress was imposed by observing irrigation intervals of 7days, 14days and 21days after irrigating the soil to field capacity. NPKMg (12:12:17:2) fertilizer was applied at 0g, 28g and 42g per seedling/polybag (based on field application rates of 0 Kg/ha, 1400 Kg/ha and 2100 Kg/ha), while the composted bunch waste was applied at 0g, 100g, 200g and 300g per seedling/polybag. Result showed that 14 days irrigation intervals gave the highest (P<0.05) effect on oil palm seedlings growth parameters compared to the 7 and 21 days intervals of irrigation. Similarly, application of 42g NPKMg fertilizer showed the highest (P>0.05) effects on growth parameters of oil palm seedlings relative to other rates of mineral fertilizers. Results also indicated that application 300gcompost/seedlings gave highest (P<0.05) effect on all growth parameters compared to other compost application rates. Interaction between the composted bunch waste, chemical fertilizer and irrigation intervals had no significant effect on all the growth parameters studied. However, combined application of 42g NPKMg compound fertilizer and 300g compost/seedlings was most effective in improving the growth of oil palm seedlings under 14 day intervals of irrigation and is therefore recommended.
