| Abstract | ||
| A field experiment was conducted in 2012 season in Tharthar region (100 km south of Tikrit city ) to study effect three levels Potash fertilization as K2SO4 ( 0 , 50 and 100 kg K2SO4 /O. ) and fifteen genotypes of braed wheat , RCBD design as asplit arrangement was used with three replicates potash fertilization was contained as main plot , while the genotypes were as sup plot . Data were recorded for twelve traits which were : the duration from planting till 50 % of spiking , plant height , no . of spikes / m2 , flag leaf area , spike length , no. of spiklet at the spike , weight of 1000 grain , total yield of the grains , biological yield , harvesting index and protein percentage . The results had shown significantly differences of potash fertilization of most traits except the till 50 % of spike formation plant height and no.of spikelets / spike . The genotypes were differed significantly in all the student traits and the interaction was significant for all the traits except the tow traits of the duration from planting till 50 % of spike formation and no .of spikelets / spike . Al – ez genotype was superior for traits of the duration from planting till 50 % of spike formation , plant height and weight of 1000 grains , while Ibaa99 genotypes was superior in tow traits no . of spikes / m2 and flag leaf area and Rasheed genotypes was superior in three traits spike length no . of spiklet / spike and no . of grains / spike ,and Maxipak genotypes was superior in traits of no . of grains /m spike , grains yield , protein percentage and biological yield and Latifieia genotypes was superior in biological yield , while Al-fatih genotypes was superior in harvest index traits . Data shwed also that the phenotypic significant for the traits of grains yield with flag leaf area no . of spikelets / spike , no . of grains / spike , biological yield harvesting index and protein percentage . | ||
