Abstract

A field experiment was conducted at Agronomic Research Area, University of Agriculture, Faisalabad during 2001-2003 to investigate the effect of different N source (urea, calcium ammonium nitrate and ammonium sulphate) and method of application (broadcast, drilling below seed and side placement) on seed yield and quality of canola (Brassica napus L). Effect of sources of N on yield and yield components was non-significant where as that of method was significant Drilling below seed and side placement increased seed yield up to 21.10 and 15.97 % and protein up to 16.45 and 15.93 % and oil yield up t016.37 and 11.37% over broadcast method, respectively.
