Abstract

This article provides a brief biology of the Tajik kovrak (F.tadshikorum Pimen.) And information on the establishment of plantations in the arable lands of Arnasay district of Jizzakh region in 2015-2019 by sowing seeds of the plant from different regions. The experiment was of two types: Option 1, in which the soil was well tilled, plowed, and then sown, and Option 2 was chiseled and then sown in seedbeds. It was found that planting resin-bearing husks in plowed areas gave better results than in chisel-planted areas. In both cases, the number of fragile seedlings has been declining over the years. It was found out that in the arable lands of Arnasay district there are opportunities for sowing and propagation of resin-bearing flakes. In order to get resin in 5-6 years, the amount of seeds sown should be 8-10 kg / ha, so that 10 thousand seedlings per hectare remain. If the seed to be sown is less than this amount, we cannot prepare the expected number of seedlings to obtain resin.
