This paper presents a practical approach of the use of a methodological system for estimating the production costs and indicative prices from the manufacturer, as well as the yield degree for the main vegetables products from Romania.. For this purpose it will be used an informational system for production technologies analysis and calculation, of the revenues and expenditures budget, as well as for specific technique and economic indicators of vegetables production. Through its complexity, the calculation system constitutes an informational guide that allows users the access to data and information on the estimates relating to the assessments of the vegetables products demand and target price from the manufacturer, in order to increase the inputs allocation and achieving high and efficient productions. Also, the content and methods of making the informational guide is based on achieving results in developing and strengthening public policies on integrated support management support schemes for farmers, promoting and forecasting the trends on the vegetable market sector in terms of absorbing potential volume of demand and supply, developing consultancy solutions and fostering knowledge transfer and innovation in agriculture.
