ABSTRACT
Two field experiments were conducted in order to evaluate the effect of nitrogen fertilization on the strength properties of rape siliques: – on one variety (Jupiter), with nitrogen used as urea to soil in spring, – on four varieties (Ceres, Liporta, Bolko, Mar), with nitrogen as 10% urea water solution to leaves. A 7 to 42% increase in silique strength was observed for urea as compared to ammonium nitrate. 10% water solution of urea caused a 10 to 51% increase in silique strength, depending on variety.
