Abstract:
A 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 ha -1 and 1.0 kg kg ha -1, respectively, along with a basal dose of 100 kg kg ha -1nitrogen (N), 75 kg kg ha -1 phosphorus (P), 50 kg kg ha -1 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.
