Two mungbean varieties were subjected to fluctuating soil moisture conditions in pot culture during kharif 1981 with a view to understand their response to similar conditions of soil moisture met with during the rainy season (kharif) in northern India. Two soil moisture levels i.e. 12–14% (2/3 field capacity) and 5–7% (1/3 field capacity) were maintained for each variety. After 20 days from sowing the soil moisture of pots from each of the two water regimes was raised to 6% above field capacity (half way between saturation moisture and the field capacity) for 7 days at a stretch. This high water treatment was repeated after 7 days.
