The effect of irrigation on diurnal changes of certain leaf moisture characteristics was studied during early bean filling in black gram. There was a reduction in leaf water potential and transpiration, while there was an increase in leaf temperature and stomatal resistance as the day advanced from 8 to 14 h. Irrigation had favourable influence on the leaf moisture characters while non- irrigation proved deleterious. Mid-day observations of the leaf moisture parameters are advisable in the screening of black gram cultivars for drought.
