Abstract

An experiment was conducted during the winter season of 1997 98, 1998 99 and 1999 2000 to study the effect of crop geometry and nitrogen levels on the seed yield and yield attributing characters of Ethiopian mustard [Brassica carinata (A) Braun]. Plant height and siliquaelplant were significantly higher when Ethiopian mustard was planted at a spacing of 60 cm x 10 cm, but seed yield was highest under 30 cm x 10 cm spacing with a population of 222, 222 plantslha. Significant response to nitrogen on seed yield, plant height and siliquaelp lant was observed at successive level up to 90 kglha. Oil content (%) decreased significantly with each successive increase in N dose up to 90 kglha.
