With the expansion of the range and appearance in the production of new species and varieties of valuable and rare greens, especially aromatic, establishment of their optimal parameters of basic agricultural practices of cultivation now has special practical importance. Growing greens in greenhouse conditions solves the problem of seasonal consumption and range, so the improved growing technology of green vegetable crops in greenhouses conditions is so important.
The influence of different seed sowing terms of five basil varieties on plant productivity, their accumulation of solids, leaf surface area and its pigment complex under conditions of greenhouses with industrial heating are studied in the article.
It was determined that netphotosynthetic productivity(NPP) of basil was influenced more by the factor of the variety: 93.5%. According to photosynthetic activity, the varieties Siaivo and Rutan were distinguished, the NPP of those was higher than of Bad`oryi control variety by 1.5 to 2.0 times, according to the studied varieties.

Key words: basil, seeds, sowing terms, biomass, leaf area, pigment complex, net photosynthetic productivity.
