STUDY OF THE GROWTH OF MULBERRY CUTTINGS ON SALINE SOILS OF THE KARSHI STEPPE

Abstract

The article presents data on the establishment of bush plantations in farms using hybrids and varietal mulberry cuttings in the conditions of the Khorezm region, which lead to the improvement of the silkworm's feed base and an increase in mulberry leaf yield. This will ensure that in the initial year of operation of the bush plantations, the collection of leaves from 1 hectare amounted to 3.5-4 tons, which is sufficient for feeding 3.5-4 boxes of mulberry silkworm cocoons. Thereby, the establishment of feed bush plantations from ringed mulberry cuttings in a permanent growing location for newly developed mulberry cuttings in the conditions of the Karshi prairie insufficiently researched, especially regarding the varietal mulberry of the Nishan district in the Kashkadarya region, which is promising. The rooting of ringed cuttings depending on hybrid combinations of mulberry was 70-90%, while for varietal unringed cuttings it was 55.5-60%. The height of one-year shoots of own-rooted mulberry plants reached 190-235 cm, with an average diameter at the base of the shoots being 1.2-1.6 cm. In the first year of operation of bush plantations, the leaf yield per hectare was 3.5-4 tons, which is sufficient to feed 3.5-4 boxes of mulberry silkworm cocoons.
