Zinc is one of the essential micronutrients require to plants for growth and metabolism. Zinc is frequently used in fertilizer to promote growth and development of plants. The aim of the study is to analyze the impact of 100 ppm, 400 ppm and 800 ppm concentration of zinc on a physiological and biochemical aspects of the wheat. Spectrophotometric methods were used to determine the biochemical parameters while growth was measured manually through centimetre ruler. The results suggest that zinc affects growth parameters positively at lower concentration. Shoot growth increase at lower concentrations and reduced at highest concentration. While Root growth, enhanced with increase in concentration. Chlorophyll content increases with lowest concentration. Protein content shows16.6% increase at 100ppm then constant decline 16.7% at 400ppm and 50% decrease in protein content recorded at 800 ppm. Elevated zinc concentration reduces sugar content, minimum lower value of.03mg/g at 8000ppm and highest 1.8mg/g recorded in control. Prolein shows highest of 83.3% increase at 800ppm, 49.5% at 400ppm and 17.3% at 100ppm zinc concentration. The control shows the lowest value for prolein. It was observed that 100ppm concentration enhances wheat growth and biochemical parameters.
