AbstractA field experiment was conducted in eastern Husiba (16Km east of Ramadi) during 2004 to study the effect of foliar nutrition of sorghum with zinc in concentraten (0,1,2) gm ZnSO4.H2O.L-1 (35%Zn) and iron in concentration (0,0.5,1,2) gm FeSO4.7H2O.L-1 (20% Fe) and interaction with it on growth and yield and iron and zinc content of sorghum variety "Inqath" . A factorial experiment was implemented according to randomized complete block design(R.C.B.D).A total of 12 treatment with three replicates were randomly assigned. Nitrogen ,phosphorus and potassium were added as urea ,super phosphate and potassium sulfate in doses (160kg N, 96kg P and 66.4 kg K).h-1 respectively on all experiment treatment. Zinc and Iron solution were sprayed in early morning at two stages ;vegetative growth and flowering stage. Plant height ,leaf area, dry matter yield, seed yield and its components were determined. Grin and leaves contents of zinc and iron were measured.
The result showed:
Zinc and iron (1gm.L-1 of ZnSO4.H2O and 1gm.L-1 of FeSO4.7H2O) showed significant increase in plant height, leaf area, dry matter, seed yields and its components. All levels of zinc sprayed significantly affected sorghum leaves and seed contents of zinc. The highest zinc content in seed was resulted from spray treatment with zinc at 2gm.L-1.All levels of iron sprayed significantly affected sorghum leaves and seed content of iron.
