| Summary, etc | Nitrogen uptake from urea applied to rubber seedings in the nursery was evaluated using 15N tracer methodology, in micro-plots established in the field. Effect of varying rates of N on growth, and the relative contribution of soil N and fertilizer N towards total N uptake were studied.Influence of rate of N application on growth of seedings was observed up to three months, and after six months, growth of plants was comparable for all the four N levels. The efficiency of N absorption by the plant, expressed as percentage N utilization ranged from 13.62 per cent at 125kg N ha-1 to 5.84 per cent at 500 kg N ha-1. The 15N balance sheet average over the four levels of N shows that about 9.27 per cent of applied N was taken up by rubber seedings, about 8.78 per cent remained in 0-60 cm depth of soil and about 81.95 per cent was unacconted N. |
