Abstract
field experiment was conducted During Autumn seasens of 2011 and 2012 to evulated the response of six varieties of maize for spray Biofertilizers (EM) Using randomize complete block design (RCBD) in order split plot with three replicates. Main plot were varities of corn (hybrid 2052 , ALMaha , ALWissam , Bohth 5012 , Bohth 5018 and Bohth 106 ) where as sub-plots were Biofertilizers (spray EM. , with out spray ) Resultswere as foflow ,the varieties showsignificant difference on means of studied characters . The hight plant , leaf area ,number of grain percob , grain weight total grain yield ton. ha -1 biological yield ton . ha-1 and harvest index .The synthetic variety 5018 gave heighest means of , grain weight , total grain yield ton . ha -1 biological yield ton . ha -1 on other Varieties , Whearase the synthetic variety 5012 gave hieghest means of leaf area , the number of grain per cob . the Bio fertilizer EM had significant effect for mean excesses of all characters control with no spray of EM fertilizer the ratis excesses 37 %, 37% of leaf erea 20.7% , 18% of number of grain per cob 13.3 % , % of grain weight , 44 % , 43 % of grain yield , 8.3 % , 7.3 % of biology yield and 16.3 % , 14.4 % harvest index . Interaction between varieties and biofertilizer (EM) had significant effect on mean of all characters studied . Finally it could be concluded that this biofertilizer may increase grain yield of all varieties studied
