The article presents the results of studies of the characteristics of growth and development, the formation of the productivity of topinambur varieties. The value of the assimilation surface of plants, the productivity of photosynthesis of various genotypes of Jerusalem artichoke was determined.

On one plant of Jerusalem artichoke varieties White yield formed the largest number of leaves - 52.4 pcs., Which is 11.8% more than control. Due to the large size and number of leaves, this variety of Jerusalem artichoke provided the maximum leaf area of a single plant - 114 cm2, as well as the leaf area from the reference areas - 63.5 thousand m-2 / ha.

 Indicators of the net productivity of photosynthesis of Jerusalem artichoke varieties were in the range of 8.3-14.2 g/m2 per day. The varieties of this crop, White Kiev and White, are high yields compared with the control, had higher photosynthesis productivity indices by 4.8-8.3%.

The mass of tubers of a single plant of the Jerusalem artichoke varieties was in the range of 304-407 g. It should be noted that White Kiev and White harvest formed large tubers of mass by 8.4-12.7% compared with the control.

Research results indicate that, on average, over the years of research (2016-2017), Jerusalem artichoke varieties had a different effect on tuber yield. Thus, the highest yield of tubers (28.5 tones per hectare) was provided by the middle ripening variety White, which is 7.3 tones per hectare more than the early varieties of Vadim (control).
