Abstract

Field experiment was conducted in a sandy loam soil during winter season of 2009 . In the Falluja city Al – Anbar Governorate to know the effect of four levels of mixed micronutrient sprayed (Fe, Zn, Cu and B ) on wheat plants which were ( 0 , 50,100,150) m.g./l in growth and yield of three wheat varieties ( Abu Ghraib , Ipa 99 and Sham6 ).A factorial experiment arrangement in randomaized complete block design ( R.C.B.D.) with three replicates . The most important result were :-
* Wheat varieties showed a different significant . The variety Ipa 99 gave a highest average in : flag leaf area , long of spike , number of spike /m2 , number pf grains per spike , weight of 1000 grain and grains yield (5.83 tan . h-1 ) . But the Sham 6 variety gave a highest rate in plant hight only .
* Spraying micronutrient showed a significant effect for all traits. The leaf nutrition in leval 100 m.g .L-1 gave a highest rate in : plant hight, long of spike and number of grain per spike . While the high level 150 m.g . L-1 gave a highest rate in : flag leaf area .number of spike /m2 , weight of 1000 grain, and grains yield (5.79 tan.h.-1).
* The interaction between varieties and sprayed micronutrient was significant effect in : flag leaf area , number of spike/ m-1 , number of grains per spike and grains yield (6.45 tan . h-1 ) .
