Evaluation of nitrogen uptake efficiency of different oil palm genotypes using 15N isotope labelling method

High demands for palm oil world wide induce the expansion of oil palm plantations in Malaysia. Malaysian soils which are highly weathered require high nitrogen fertilizer input in order to maintain high yield output, resulting in increase in production cost as well as inducing negative impacts to th...
