The large number of variables were highly significant in determining scientific grades, pungency (0.78), total sugar (6.46), weight of onion (5.87), moisture percent (6.39) weight of potato (5.27), number of seeds (4.53) whereas, very few variables were significant in the case of eye-sight grades Black soil (0.78), Uniformity dummy (1.98), red soil (0.56),Market distance (-8.37)  in that they take majority of the factors into consideration while eye-sight grades either do not take several factors into account or they have the sign contrary to the expectation. It is evident from this study that scientific grading is superior compared to eye-sight grading. It is also evident that the eye-sight graders have failed to properly judge the quality of the produce. If this kind of anomalous grading system is continued, the farmers will lose confidence in the present grading system. Hence, it is strongly suggested that eye-sight grading must be replaced by scientific grading method. Scientific grading can help the farmers to fetch higher prices commensurate with the quality of the produce and well also promote the orderly marketing system in the country.
