Abstract
- The article presents the results of studying the growth, formation of leaf surface, productivity, and marketable yield of various very early, early, and mid-early potato varieties with double cropping: planting with freshly harvested tubers in summer. It was revealed that the studied varieties differ significantly in the germination of tubers, the formation of top stems, and leaf surfaces, as well as in marketable yield. The highest field germination of tubers (95.2-98.7%), stem formation (2.9-3.8 pcs.), leaf surface (33.6-39.9 thousand m² per 1 ha), photosynthetic potential on plantings (2590.0-3351.6 thousand m2), powerful tops and root systems with intensively accumulating yield, as well as the largest commercial yield (29.1-34.3 t/ha) were obtained from the varieties: in very early- Latona, Binella, Karatop, Ultraeshim; in early - Arizona, American, Yangi Uzbekistan; in mid-early - Evolution, Pikasso, Sylvana, Saviola. At the same time, the yield increase was 2.6-8.7 t/ha compared to standard varieties. [ABSTRACT FROM AUTHOR]
