An experiment was conducted during the 1981-1983 winter seasons in pots containing soil deficient in zinc to study the influence of zinc application on lentil yield and yield attributes. Among the 14 treatments of zinc application, 1) foliar sprays of ZnSO4 at 15 and 45 days after emergence followed by 2) foliar sprays of ZnSO4 at 15 and 30 days after emergence then 3) seed coating with ZnO at 0.20% and basal application of zinc sulphate at 10 kg Zn/ha in descending order resulted in increased grain straw and biological yields/plant above the control. Yield attributes namely number of branches/plant, pods/plant, seeds/pod, and 1000-seed weight were also higher than the control when zinc was applied either as foliar sprays of ZnSO4 at 15 and 45 days after emergence or as a seed coating of ZnO at 0,20%. Maximum harvest index was recorded from foliar sprays of ZnSO4 at 15 days after emergence and seed coating with ZnO at 0.10% during the first and second year, respectively
