Effects of Source and Rate of Nitrogen Fertilizer on Yield, Yield Components and Quality of Winter Rapeseed (Brassica napus L.)

Winter rapeseed (Brassica napus L.) has potential to become an alternate oilseed crop both for edible oil production and energy agriculture (biofuel production) for Turkey. This study was conducted to determine the effect of year, N sources and doses on the yield and quality traits of winter rapesee...

This study was conducted to determine the effect of year, N sources and doses on the yield and quality traits of winter rapeseed in a cereal system in calcareous soils over two seasons, 2000-2001 and 2001-2002, in Central Anatolia. Three N sources, ammonium sulfate, ammonium nitrate and urea, were applied as hand broadcast on the soil surface at five doses (0, 50, 100, 150, and 200 kg N ha-1). The traits investigated were plant height, number of branches and pods per plant, number of seed per pod, thousand seed weight, seed yield, oil and protein content. There were significantly effects on seed yield, oil and protein content, and other yield components due to N sources and rates. In general, ammonium sulfate and urea gave higher seed yield than ammonium nitrate. Mean values of both seasons indicated that 100 and 150 kg N ha-1 rate increased significantly yield and quality traits with regard to other N treatments. The present results highlight the practical importance of adequate N fertilization and true N source in seed yield in winter rapeseed and suggest that ammonium sulfate at 150 kg N ha-1 will be about adequate to meet crop N requirements.info:eu-repo/semantics/openAccessInstituto de Investigaciones Agropecuarias, INIAChilean journal of agricultural research v.70 n.1 20102010-03-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-58392010000100014en10.4067/S0718-58392010000100014
