| Abstract | ||
| A field experiment was conducted at the experimental farm, Dept. of Field Crop, Coll. of Agriculture, Univ. of Baghdad,during 2011-2012 Winter Season, to Study the effect of potas-sium fertilizer levels and appilication stage on some growth characteristies and physiological indexs of wheatTriticumaestivum L. ( Var-Abu-Ghraib-3).Factorial experiment was conducted with RCBD design with three replications involved two levels of Pottasum 120, 180 Kg.ha-1, and control treatment the second factor was three stage of application (tillering , Booting, flowering).The stage, results showed, 120 Kg.K.ha-1 was Superior in (dryweight, crop growth rate, relative groth rate in physiology maturity with an increase of 4.82,4.77, 0.73% as com-pared toapplication level 180 Kg.K.ha-1 , which was superior in flag leaf area, chlorophyll concentration and spike length with an increase of 14.08, 9.74, 13.34% as compared to potas-sium application in 120 Kg.K.ha-1. Application stages was superior in plant hight, Chlorophyll concentration and application potassium attillering gave dry weight high, The highestcrop growth ratand, relative growth rate were 614.59 gm, 13.21gm.m-2.day-1 0.0411 gm.gm-1.day-1.The interaction between two factors was significantly in all characteristicsa studying. | ||
