SELECTION OF PROMISING SWEET POTATO VARIETIES SUITABLE FOR THE SOIL AND CLIMATIC CONDITIONS OF THE TASHKENT REGION

Abstract

 In this article, sweet potato seedlings with stem lengths of 15–20 cm and aged 41–46 days in the greenhouse were ready for field planting. To increase the survival rate of the seedlings in the greenhouse, they were dipped into a working solution prepared with the growth stimulator Kornevin before being transplanted into the open field. During planting, the seedlings were hand-planted in a double-row belt method with a row spacing of 70 cm, belt spacing of 140 cm, and 40 cm between seedlings. Six varieties imported from Russia were studied in the experiment. The trial was conducted with four replications, and the feeding area was 16.8 m². The seedlings were planted according to the 140+70/2×40 cm double-row belt scheme. The total experimental area was 740 m², with each plot measuring 8 m in length and 2.1 m in width, and 40 plants were placed in each plot.
