Abstract

The goal of the research is to evaluate the collection of samples of the catnip plant in Uzbekistan according to morphological and economic valuable characteristics, and on this basis to distinguish promising varieties and plant them in different periods, to determine the optimal planting periods for growing high-quality seeds, to conduct a biochemical analysis of the grown crops, and to determine the yield in green mass and dried. Methods of conducting experiments in vegetable, potato and potato crops in conducting research used style and methodological instructions. Research was carried out on the Barkhat variety, which was selected as a result of a comprehensive study of Catnip’s Basilio, Centaur, Barkhat and Goluboy Iney varieties. Experiments were carried out in the spring and autumn terms. Seedlings were grown in unheated greenhouses. Seedlings are planted in the open field in a 70x25 sm planting scheme. It was found that the weight of one plant in the autumn period was 82%, the number of branches was 46–70%, and the leaf mass was 83% more than in the spring period. When studying the biochemical composition, it was found that it contains 21.8% dry matter, 3.6% sugar, 6.8% protein, and 13.8 mg% vitamin. Essential oils from the plant were analyzed by the method of chromato-mass spectrometry, in which 54 different biologically active substances were identified. The seed productivity of the Catnip plant was 56 g/plant in spring and 87 g/plant in autumn. The conducted scientific research has shown that the successful cultivation of catnip in the south of Uzbekistan and, on this basis, provides an opportunity to provide the population with a rare vegetable crop with another valuable content throughout the year.
