The combined data over years and fertility levels indicated that despite taking up similar amounts of N, genotypes differed significantly in biomass production and thus in N use efficiency. A West African genotype, Souna B, had N use efficiency values 32% higher than the less efficient Indian genotype BJ 104 even though both genotypes had similar N uptake. An increase in N fertility decreased N use efficiency since the percentage increase in biomass was smaller than the percentage increase in N uptake. date: 1985 date_type: published series: Developments in plant and soil sciences volume: 27 publisher: Martinus Nijhoff place_of_pub: Dordrecht pagerange: 281-286 pages: 629 refereed: TRUE isbn: 978-94-010-8102-3 book_title: Genetic Aspects of Plant Mineral Nutrition: Proceedings of the Second International Symposium on Genetic Aspects of Plant Mineral Nutrition, organized by the University of Wisconsin, Madison, June 16–20, 1985 editors_name: Gabelman, W H editors_name: Loughman, B C related_url_url: http://scholar.google.co.in/scholar?as_q=%22Genotypic+variation+in+biomass+production+and+nitrogen+use+efficiency+in+pearl+millet+[Pennisetum+americanum+%28L.%29+Leeke]%22&as_epq=&as_oq=&as_eq=&as_occt=title&as_sauthors=&as_publication=&as_ylo=&as_yhi=&bt related_url_type: pub citation: Alagarswamy, G and Bidinger, F R (1985) Genotypic variation in biomass production and nitrogen use efficiency in pearl millet [Pennisetum americanum (L.)
