Micronutrients have globally proven importantance in agriculture. The deficiency of micronutrients is an expected trend among cereal crops which confines yield and nutritional value of grains. A field trial was laid out to evaluate the effect of micronutrients on yield and quality of maize in randomized complete block design (RCBD) at Agronomic Research Area, University of Agriculture, Faisalabad . The treatments comprised of no micronutrient application (control), water spray and foliar application of micronutrients mixture @ 250, 500, 750, 1000, 1250 and 1500 ml ha at stem elongation stage of maize. All micronutrients treatments significantly improved plant height, cob length, number of grains rows cob , cob weight, 1000-grain weight, grain yield, biological yield, harvest index, grain protein and grain oil contents. However, micronutrients application at stem elongation stage showed non-significant effect on plant papulation and number of cobs plant . Therefore, for attaining maximum yield of maize, it is suggested that 250 ml ha at stem elongation stage of maize should be used.
