A study was conducted in the laboratory to know the effect of diluted sewage water on the germination and seedlings growth of some pulses like green gram (Phaseolus radiatus), horse gram (Vigna unguiculata), Bengal gram (Cicer arietinum) and cow pea (Phaseolus cylindricus). The seeds were soaked in diluted sewage water (1:1) overnight and germinated in Petri plates. The germinability and seedling growth was compared with that of control which consisted of seeds soaked and germinated in bore well water. The observations made for five days showed a 4-6 hours delay in germination of pulses treated with sewage water compared to the control. Further they showed only 66- 78% germination and 80-84% survivability as compared to those treated with bore well water which showed 89-98% germination and 92.6- 94.4% survivability after five days. Among the pulses treated with sewage water, the worst affected was the horse gram seeds which showed 30% less germination, 32.2% reduction in length of germ tube and 14 % less survivability than control. The least affected was the green gram which showed 11% less germination, 23.6% reduction in length of germ tube and 8% less survivability than control. Besides these negative effects, the sewage water treated seeds were contaminated with fungi and infested with some insects larvae with foul smell. The sericulture farmers who practice intercropping/ green manuring with leguminous plants may avoid the usage of sewage water for irrigating their mulberry gardens.
