Muralidharan, A.Biddappa, C.C.2014-07-232014-07-231993Journal of Plantation Crops 21(Supplement):51-57 (1993)http://hdl.handle.net/123456789/4372A pot culture experiment was conducted with six month old oil palm seedlings for a duration of 18 months, to study their growth characteristics and the total nutrient contents with respect to graded levels of nitrogen (specific levels being: 0,100, 200 and 400 ppm nitrogen per seedling per year). Increased levels of nitrogen significantly increased different growth parameters. The seedlings receiving no nitrogen (No level) were found to manifest foliar yellowing and stunted growth. The percentage distribution of biomass at N0 level showed that the root constituted about 45 per cent of the total biomass; while in the case of N100 N200and N400 levels, they were only 25.1,2.8 and 20.2 percent respectively. Distribution of total nitrogen content of the seedlings indicate that at all levels of nitrogen application, 53 to 60 per cent of its total content was locked up in leaf, 7 to 12 per cent in petiole, 12 to 16 per cent in stem, and 14 to 29 per cent in root. The total content of other nutrients increased significantly with increasing levels of nitrogen.enArticle
