The bio-stimulator application for improving the quality of lettuce green mass

The influence of the bio-stimulators on the sprouting energy indices, lettuce seed germination, plant development dynamics in the vegetation experiment is assessed. The assessment of the green mass quality is conducted on the height, weight and ascorbic acid content. The dependence between the indices of the vitamin C content, plant weight and height is revealed. On the optimal combination of plant mass indices, its height and ascorbic acid content, the use of Ferovit and HB -101 preparation can be considered to be the best option for growing lettuce in greenhouse conditions.
