THE EFFECT OF CO2 SUPPLY ON THE YIELDING AND ECONOMIC CONSEQUENCES OF THIS TREATMENT IN GLASSHOUSE CULTIVATION OF TOMATOES

Eugeniusz Ko這ta, Zbigniew 奸您ak

 

ABSTRACT



The studies conducted in a glasshouse of the Establishment of Horticultural Production (PPO) at Siechnice were aimed to determine the reaction of tomatoes grown on mineral wool to CO2 enrichment of the atmosphere and to calculate the profitability of applying this treatment in wholesale production. The studies used liquid gas accumulated in pressure containers. After being evaporated, the gas was carried in liquid form to plants by means of a system of PE pipes. The studies adopted three levels of CO2 content in the glasshouse atmosphere, namely 0.06-0.08% with ventilators closed, 0.04-0.05% with ventilators slightly opened, and 0.03-0.04% with ventilators fully opened.

Key words: tomato, glasshouse cultivation, CO2 enrichment, yield, profitability of cultivation.
