Abstract: The main local producers of fresh vegetable products to the population of Nizhny Novgorod and the region are greenhouse mills "Zhdanovsky" and "Gorkovsky," but they do not provide the region with fresh vegetable products due to low yield compared to world technologies. The aim of the research was to study the LED lamp on the growth and development of cucumber in the winter greenhouse in "Zhdanovsky" of the Kstovsky district of the Nizhny Novgorod region. Yield (kg/m2) was taken into account by cucumber for the whole period of turnover. Standard and non-standard greens were counted by weight and quantity method. Cucumber productivity ranged from 25.32 kg/m2 in the 3rd variant (control) to 36.10 kg/m2 in the 2nd variant (LED and high pressure sodium lamps). The yield of standard cucumber production varied from 81.7‰ in option 2 to 95.5‰ in option 1 (LED). Vitamin C content in cucumber varied from 15.75 mg‰ in variant 3 to 17.46 mg‰ in variant 1. Sugar content in cucumber varied from 1.15‰ in variant 3 to 2.00‰ in variant 1. The lowest percentage of dry matter was accumulated in variant 2 - 3.78‰, the largest - in variant 1 - 4.13‰. The LED lamp during operation gives an advantageous effect in the form of annual savings in the amount of 1381 roubles/m2. The payback period of the LED lamp will be 2.9 years.
