Abstract:
A study was designed with the objective to assess the impact of sewage water on radish cultivation during 2002-03. Dummy variable was used to estimate the impact of sewage water on radish yield. Production function having independent variables like land preparation, seed, fertilizer and labour along with dummy variable and interaction terms between dummy- variable and other independent factors was used to assess the response of different inputs like seed, fertilizer, land preparation, etc. due to sewage water. The findings of the study showed that by the introduction of interaction terms in the model, the coefficients of seed and insecticide variables changed significantly. This model also indicated that sewage water reduced the efficiency of tractor hours used for land preparation and fertilizer. The results of this study depict several policy actions to be taken immediately to preserve soil productivity and to reduce the health hazards. The most important step is to treat sewage water before applying to crops and those vegetables that are tolerant to sewage water and leafy ones should be irrigated by this type of water and conjunctivee use of sewage and canal/tube-well water must be practised to maintain soil productivity.
