A field experiment was conducted during rabi season of 2017-18 at Agricultural College Farm, Bapatla to study the impact of seed pre - treatment and foliar application of zinc on leaf growth parameters of mungbean under water stress. The experiment was laid out in split plot design with three replications consists of two main treatments viz., no stress i.e. control (M0) and stress from flowering stage (i.e. from 30 DAS) up to harvest (M1) and seven sub-treatments viz., no zinc application (S0), seed treatment with 0.05% and 0.075% ZnSO4 solutions for 5 hrs before sowing (S1 and S2), foliar spray of 300, 400 and 500 ppm ZnSO4 at 30 DAS (S3, S4 and S5) and water spray at 30 DAS (S6). The results showed that leaf area was reduced by 14.8 per cent in the plants that were subjected to stress from flowering stage over control plants. Foliar zinc spray @ 500 ppm at 30 DAS increased the leaf area by 30.0 per cent, over untreated plants at 45 DAS. Normal irrigated plants sprayed with zinc @ 500 ppm (M0S5) recorded the highest values of leaf area and the lowest values were recorded by the stressed plants with no zinc application (M1S0). Under water stress, mungbean plants sprayed with zinc @ 500 ppm at 30 DAS (M1S5) increased the leaf area by 23.9 per cent, over unsprayed plants (M1S0).
