• A field study was conducted at Agronomic Research Area, University of Agriculture, Faisalabad during spring, 2007 to evaluate the effect of different chelated zinc sources on growth and yield of maize (Zea mays L.). Crop was sown on well-prepared soil in 1st week of March 2007. The experiment was laid out according to randomized complete block design. The treatments comprised of different chelated zinc sources: ZnSO4-DTPA, ZnSO4-Fulvate, ZnSO4-Lignosulphonate, ZnSO4-EDTA and ZnSO4-H2O along with control (no zinc) repeated three times. Results showed that number of cobs per plant, grain rows per cob and oil contents did not differ significantly. However, differences among treatments for plant height at harvest (cm), leaf area per plant (cm-2), stem diameter (cm), cob length (cm), cob diameter (cm), 100-grains weight (g), number of grains per cob, grains weight per cob (g), biological yield (tons per ha), grain yield (tons per ha) and protein co ntents (%) were significantly higher. Moreover, results also revealed that ZnSO4-DPTA was found the most effective Zn chelated source among all the treatments. Rest of the chelating agents were not too impressive as they showed varied response for different variables. The result of this experiment suggest further experimentation to explore behaviour of Zn-DTPA with other macro and micro nutrients and to calculate cost benefit ratio for use of Zn chelated compounds.
