GREENHOUSE VEGETABLE PRODUCTION IN THE FUNCTION OF SUSTAINABLE AGRICULTURAL PRODUCTION

A significant segment within the sustainable development of agricultural production and economic prosperity is production in controlled conditions, such as production in greenhouses and glasshouses. In the Republic of Serbia, vegetable production is almost entirely concentrated on family farms. Considering the importance of family farms, the subject of this study is a comparative analysis of vegetable production on family farms and vegetable production in greenhouses, as well as open-air vegetable production. In this context, the paper presents two models for optimising the vegetable production structure, using the method of linear programming and the software package LINDO. The first model refers to vegetable production in greenhouses (variant I) and the second one is formulated for open-air vegetable production (variant II). The analysis and solving models have pointed to differences in the optimal sowing-planting structure, in the number of independent variables or vegetables included in models, but also in realised net income, wherein variant I achieves both higher net income per hectare and higher production economy.
