A field experiment was conducted in a randomized complete block design with three replications at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif 2017 to elucidate relative efficiency of ZnSO4.7H2O and Zn EDTA on the photosynthetic character and yield attributes of pearl millet variety ICMV-221. Two sources of Zn i.e. ZnSO4.7H2O and Zn EDTA were soil applied as basal dose @ 0 (control), 5, 10, 15 and 20 kg ha-1 before the sowing. Application of 20 kg ha-1 Zn EDTA showed earlier attainment of growth stages viz. flag leaf initiation, 50 % flowering and milky stage whereas physiological maturity was late. Leaf area, Chlorophyll content, SPAD value, leaf Zn content, photosynthetic characters, yield attributes viz. grain yield plant-1, grain yield ha-1, test weight, harvest index also reported being highest with 20 kg ha-1 Zn EDTA followed by 20 kg ha-1 ZnSO4.7H2O, indicating the efficiency of Zn EDTA compared to ZnSO4.7H2O.
