Abstract

A field experiment was conducted at the Experimental Farm, Department of Field Crops Sciences, College of Agriculture, Abu-Ghraib during 2001-2002 and 2004-2005 season to determinate the best interaction effect between nitrogen and phosphorus gave a higher yield and quality of white mustard. The layout of the experiment was RCBD with three applications. The results showed that the combination of 280 Kg N/h and 55 Kg P/h surpassed the other treatments in plant height, number of branches/ plant, number of capsule/plant weight of 1000 seeds, yield of plant. Number of seeds/ capsule and percentage of oil in seed were not significantly affected treatments compared with control. The combined effect of 280 Kg N/h and 55 Kg P/h produced the highest seed yield 6.39 gm. 9.28gm compared with control 2.80 gm, 4.66 gm in both seasons, respectively.
