Abstract
This study compared two locally engineered LED irradiators (KSDO-1 and KSDO-2) for their efficiency in accelerating growth and productivity of greenhouse tomato (Solanum lycopersicum L.).The work was motivated by the need for energy-saving, crop-specific lighting to enable year-round tomato production in northern Kazakhstan.Experiments were conducted at the LedSystemMedia greenhouse complex (Astana, Kazakhstan) using the F1 hybrid 'Forticia RC' grown hydroponically.Plants were illuminated with either high-pressure sodium (HPS; control) or one of the two LED treatments.Main physiological and morphological parameters, such as plant height, internode length and leaf area.Quantum yield of photosystem II (Y(II)) and fruit productivity were measured during the vegetative and reproductive periods.The biochemical content of the fruits was also determined.Measurements were made according to standard national methods and with the help of specialized equipment (MINI-PAM-II fluorometer).Tomato plants subjected to LED treatments.Particularly, KSDO-2 showed significantly better performance.The total yield was enhanced by 150.2% (KSDO-1) and 152.6% (KSDO-2) compared to the control.Increased photosynthetic efficiency shortened internodes, increased leaf area (by 20-24%), and extended fruiting periods were found under LED illumination.No differences were noticed in fruit biochemical quality among the treatments.The results indicate that LED irradiators designed according to plant photosynthetic requirements have the potential to significantly increase tomato production in controlled environments.The KSDO-2 model proved to be the most efficient and is now being prepared for patenting, being a promising development in energy-saving greenhouse lighting technology.
