Abstract

One pot experiment was carried out at during May, 2000 through July, 2000. Seeds were sown in soils of earthen pots and then the pots along with soil were dipped in water for 12, 24, 36 and 48 hours. Results showed that significantly lower values of almost all the growth and yield parameters were found with successive increase in duration of water logging. Highest number of leaves/plant (13.00), highest leaf area (1321 cm2), highest plant height (60 cm), highest dry matter (22.21 g/plant), highest 1000 seed weight (39.52 g), highest number of pods/plant (18.70), highest seed yield/plant (7.06 g) and highest harvest index (31.78%) were found when pots were not emerged in water. Whereas, lowest number of leaves/plant (5.00), lowest leaf area (862 cm2), shortest plant height (40.25 cm), lowest dry matter (13.17 g/plant), lowest 1000 seed weight (30.12g), lowest number of pods/plant (6.49), lowest seed yield/plant (1.81 g) and lowest harvest index (13.17%) were found when pots were emerged in water for 48 hours. Date of both flowering and maturity was also delayed due to water logging. However, days from flowering to maturity was hastened due to water logging by almost one day. Water logging for 12, 24, 36 and 48 hours showed reduced seed yield of 12.47, 27.17, 46 and 74.36% respectively.
