The paper presents preliminary results from the research field regarding the effect of wide length infrared radiations upon different types of vegetable crops, under a direct monitoring of microclimate. The experimental plot was emplaced in classic ”Prinz-Dokkum” glasshouses from Baia Mare, Romania. The experimental factors where: control (without the influence of wide length infrared radiations) and tested experimental factor (with the influence of wide length infrared radiations). The research and observation activity followed the main steps: on-line microclimate monitoring for the following parameters: temperature 22°C (18 - 22°C) and relative air humidity 55% (50 - 70%), seedling monitoring for 7 species of vegetables and 4 species of flowers, phonological and biometrical measurements, glasshouse environment monitoring, photo recordings for the main stages of growth and development, prevailing and creating a data base with the help of different electronic devices. The obtained results reveal that the presented technology can be successfully implemented in protected spaces cultivation, the next step of research consisting in practical optimizations in a modern agriculture.
