Abstract

Cotton growing is the main industry in Uzbekistan’s agriculture, and the country has accumulated a great deal of scientific and practical experience in cotton growing. A number of scientific studies is being undertaken in this regard. Especially in the cotton industry of the republic in recent years, the widespread use of physiologically active substances in the cultivation of fairy tales, high and quality crops has achieved positive results. Physiologically active substances are added to the soil, or the seed is applied to the seed before planting and can be used during the cotton growing season. We believe that the physiologically active substances used have a natural basis and their safety can play a special role in the cultivation of organic cotton. This article explores the potential for seed germination, cotton growth and development, and the cultivation of future, high-quality, environmentally friendly cotton whenTevevit Bomsphysiologically active substance is applied at a rate of 300-1,000 kg/ha during the preparation of the soil for planting without the use of chemical mineral fertilizers.

Highlights

Due to the fact that Uzbekistan ranks 5-6 among the largest cotton-growing countries in the world and cotton is grown on more than 1.0 million hectares, the cotton crop is exported to more than 30 countries in the form of fiber, yarn and other products and this is of economic importance of the country [1, 4]
With the germination of seeds treated with physiologically active substances, plant growth and development are improved, resistance to drought, salinity, disease increases, natural soil fertility and efficiency of mineral fertilizers are increased, creating the basis for high and quality yields [9, 11]
No research has been conducted on the biological efficacy of the new Tevevit Boms medicine in cotton and no optimal standards and timing of its use have been developed, which is the basis for this research

Summary

Introduction

Due to the fact that Uzbekistan ranks 5-6 among the largest cotton-growing countries in the world and cotton is grown on more than 1.0 million hectares, the cotton crop is exported to more than 30 countries in the form of fiber, yarn and other products and this is of economic importance of the country [1, 4]. With the germination of seeds treated with physiologically active substances, plant growth and development are improved, resistance to drought, salinity, disease increases, natural soil fertility and efficiency of mineral fertilizers are increased, creating the basis for high and quality yields [9, 11]. When cotton seeds of Aqdarya-5 variety were treated with stimulants T-86, Nitrolin, Tj-85 and XS-2, field productivity increased and growth accelerated development, had a positive effect on leaf surface, cotton yield and fiber quality. In such experiments [13, 14], when the seeds were treated with ‘Mival’ before sowing, they germinated smoothly and healthy, despite adverse weather conditions. No research has been conducted on the biological efficacy of the new Tevevit Boms medicine in cotton and no optimal standards and timing of its use have been developed, which is the basis for this research
