| Abstract | ||
| A field experiment was conducted at the field of Alnasser-irrigation project in Basrah Governorate during the growing seasons of (2009-2010) to study the effects of three levels of Potassium fertilizer (0,50,100 and 150) Kg K. ha-1 from potassium sulfate (K %41.5) and three levels foliar application of Zn (0,1,2) kg Zn.ha-1 as Zinc Sulphate ZnSO4.7H2O(23%Zn).on some growth characteristics, yield and its components on wheat (var.IPA-99), factorial experiment by use R.C.B.D Design by three replicate. The results showed the positive impact of potassium fertilization in all the studied parameters ,the application level l50 Kg K. ha-1 caused highest average in plant height, flag leaf area, no. Spikes/m2,1000 grain weight, no. of grains. spike -1 and grain yield there were 3.45 and 3.48 ton/ ha for two seasons respectively, foliar application of Zn at level 2 Kg Zn.ha-1 gave high plant height, flag leaf area, no. Spikes/m2,1000 grain weight, number of grains.spike-1 and grain yield there were 3.24 and 3.27 ton/ ha for two seasons respectively, The results also showed that interaction of potassium and zinc foliar on plant height, flag leaf area, no. Spikes/m2 and grain yield was significant. The interaction between l50 Kg K.ha-1 and 2Kg Zn.ha-1 gave the highest, no. Spikes/m2,1000 grain weight and grain yield were produced 3.58 and 3.53 ton/ ha for two seasons respectively. | ||
