Effect of different packaging treatments of Urea fertilizer and agricultural distances between lines and plants on the yield of sunflower

This experiment was applied according to the arrangement of split plots design by using a randomized complete block design (R.C.B.D) with three replications, the planting distances were filled with (40 ×40), (50×50), (60×60), and (70×70) for the main plots, while the packaging parameters (Zeolite + cement) were set. And (white cement only), (zeolite only) and regular (comparative) urea in the secondary plates (subplot). The result showed the significant effect of planting distances between lines and plants, as the distance (70×70) was superior to the traits of the weight of 1000 grains and the yield, the individual plant gm plant-1 78.00 gm and 78.48 gm plant-1 respectively The distance (40×40) was superior by giving the highest rate for the trait of total grain was 79.92 g, while the distance (70×70) and the packaging treatment (zeolite only) superior by giving the highest mean for the trait of the yield of the individual plant gm plant which reached which reached 80.30 gm.
