RafiqueR. 102000310A field experiment was conducted in a commercial wheat grower's field, to study the combined effect of micronutrients, zinc (Zn), copper (Cu), iron (Fe), manganese (Mn), boron (B) and a source of commercial micronutrients called Zarzameen on the yield and the yield components of wheat crop at Wahid Garhi, Peshawar, Pakistan. Different combinations of Zn, Cu, Fe, Mn, B and Zarzameen were applied at the rate of 4.0, 2.0, 5.0, 2.0, 1.0 kg ha1 and 1.0 kg ha1, respectively, along with a basal dose of 100 kg ha1 nitrogen (N), 75 kg ha1 phosphorus (P), 50 kg ha1 potassium (K). The fertilizer treatments (macro and micro nutrients) increased wheat dry matter, grain yield, and straw yield significantly over control. Soil contents of B and Zn were increased both at boot and harvesting stage and Fe only at boot stage with the addition of micronutrients. Plants of -B treatments had showed classical B deficiency symptoms at grain formation stage but not at vegetative stage. Boron concentration in the dry matter of wheat plants increased with the addition of the B fertilizer in the soil. Results of the experiment demonstrated that soil under experiment was deficient in B with the deficiency of N, P or K.]]>Alkan, A., B. Torun, N. Koleli, I. Cakmak, M. Kalayci, H. Ekiz and A.
