Eggplant culture gets a particular attention in the western part of our country, being intended for it in the established vegetable basins from Arad and Timis counties considerable surfaces both in the field and in greenhouses and solariums or in other shelters made of plastic. In order to ensure the profitability of the culture on the background of the continuous increase of prices of any kind of energy (thermal, electrical, fuels, and so on) there have been many improvements in the culture technology: replacement of the natural culture substrate (soil) in greenhouses and solariums, utilizing at a large scale the drip irrigation and implicitly fertigation, introducing in culture new performant hybrids in terms of productivity and quality, the use in vegetation of some foliar bioactive products in the purpose of obtaining a better biding of flowers/ setting of flowers and faster growth of fruits, to achieve a better resilience to extreme temperatures (low after planting in the field and extremely high in the summer - July, August), and so on. There was a need of increasing the photosynthetic yield of plants in order to make the most of the entire productive potential of the hybrids used in culture. This paper presents the way to solve this aspect of the culture technology.
