Effect of different levels of Phosphate fertilization in yield and components for three cultivars of Wheat crop (Triticum aestivum L.)

Abstract

Abstract A field experiment was conducted during winter season of 2013-2014 at AL- shinana that belong to AL-Qurna about ( 65) Km north Basrha in silty loam soil in orderto determine the best production of the three cultivars of wheat Triticum aestivum L, (Abu Graib-3 , Tammoz – 2 and Latifia ) to determine the best level of phosphate fertilizer (0 , 40 , 80 , 120 kg P2O5 hˉ1 ) ,The experiment design was R C B D with treatments arranged in factorial in three replicates ,The results showed that Abu-Graib cultivar was gave the highest of grain yield ( 6,98 ton,hˉ¹ ) with the fertilizer level 120 kg P2O5 hˉ1 compared to the cultivars Tammoz – 2 and Latifia who was given grain yield 6,54 , 6,51 ton,hˉ¹ straight , the increase in grain yield Abu-Graib due to higher yield components number of spike m-2 (638, 86) and 1000- grain weight (31,09 gm),
