| Abstract A field experiment was conducted at AL-Shinana which is about (65) Km north of Basrah during 2013/2014 . The aim of this study was figure out the effect of four levels of NPK fertilizer (15:15:15 ) (F₀) zero Kg.hˉ¹ , (F₁) 200 Kg.hˉ¹, ( F₂) 400 Kg.hˉ¹ , and (F₃) 600 Kg.hˉ¹ on growth of five varieties of wheat ( Triticum aestivum L.) ( Bhooth -158 , IPA-99 , Bhooth -22 , Abu-graib -3 and Fateh ).Farther quantity of Nitrogen was added in from Urea and the quanties were ( 0 , 66 , 132 , 198 ) Kg Urea , so the full quantity of Nitrogen will became (60 , 120 and 180 )Kg N . hˉ¹ . The experiment was conduct by using split- plot design and the varieties sub-plot represented because they were the most important factor in this study .While in the main plot were the levels of NPK fertilizer . The randomized completely block design was used with three replications in a soil which is a silt clay loam texture. The results showed that ( Bhooth -158) was superior in area of flag leaf in the lowest number of days of planting to 50% spiking and the longest number of days from 50% spiking until maturity . Abu-graib -3 was superior in plant height and number of tiller . mˉ². IPA-99 was superior in spike length . The results showed that the level (F₃) was superior in the number of days from 50% spiking to maturity ,the plant height , the area of flag leaf and spike length .The level(F₀) was superior in the lowest number of planting to 50% spiking . The level(F₂) was superior in the number of tiller . The interaction between cultivars and NPK fertilizer levels gave significant interaction in which ( Bhooth-158× F₀)gave the lowest number of days of planting to 50% spiking and ( Bhooth-158× F₃) superior in hightest number of days from 50% spiking to maturity and the area of flag leaf .( Abu-graib -3 ×F₃ ) in plant hight and number of tiller (IPA-99×F₃)in spike length. | ||
