Rapeseed (Brassica napus) has been introduced recently in the pampean region, Argentina. Our objective was to assess the nutritional status of the crop under the usual relatively low nutrient supply of the area, aiming for a rational fertilization policy for this oil crop. Two cultivars were studied on a Vertic Argiudoll, at the experimental field of the Faculty of Agronomy, University of Buenos Aires. Plant samples were taken at the stages of rosette, elongation, flowering, and maturity. Dry matter and nitrogen (N), phosphorus (P), and potassium (K) contents were determined. Plant nutrient concentrations were within the range of plants grown under high nutrient supply, but the yields were low. The differences in growth rate did not means different total nutrient absorption. The seeds exported between 74 and 79% of the absorbed N and P, but K remained largely in the straw. |
