The present paper attempts to estimate the non- qualitative characteristics influencing price of important vegetables marketing in Karnataka.  The non-qualitative variables namely variety, uniformity of onion, potato, tomato and brinjal in a lot, quality information the farmer had at the time of sale, source of quality information, types of buyer, size of production unit, area under crops, distance to the market, number of basket per lot, types of soil and day of sale which were hypothesized to influence prices received by onion, potato, tomato and brinjal producers. In case of aggregate markets, the regression coefficients for black soil (111.72) and source of information APMC dummy (42.58) were found to have positive sign. It indicated that the onion grown in black soils yielded more and also attached good quality as evidenced by the results. It revealed that own experience (-94.89) and commission agents (-87.70)had negative influence on the price of potato. That means dummy for the own experience and dummy for the commission agents in aggregate markets were less conscious and they quoted less price for the potato. Present studies were useful in determining the most influential non quality factors affecting the price of vegetable included.
