Abstract: this article discusses the development and growth of different varieties of cotton, yields in the region "Bukhara-102". Development and implementation of the AIC system based on the existing natural, soil, ameliorative and hydrogeological conditions. The most important and important factor in our perception is the need for soil, the condition ofplants, which is understood by experts in all fields. Based on the above, it is necessary to study the norms of S-6524 (default), Bukhara-102, water supply norms (NPC) and irrigation procedures on typical coarse soils that occupy a certain part of the country's soil. This is one of the problems.
Keywords: cotton, harvest, Bukhara, variety, agriculture.

Аннотация: в данной статье рассматривается развитие и рост разных сортов хлопка, урожайности в регионе "Бухара-102 ". Разработка и внедрение системы АПК на основе существующих природных, почвенных, мелиоративных и гидрогеологических условий. Самым важным фактором в нашем восприятии является потребность в почве, состояние растений, что понимают специалисты во всех областях. Исходя из вышеизложенного, необходимо изучить нормы S-6524 (по умолчанию), Бухара-102, нормы водного питания (NPC) и процедуры полива на типичных грубых почвах, которые занимают определенный участок почвы страны. Это одна из проблем.
Ключевые слова: хлопок, урожай, Бухара, сорт, сельское хозяйство.

One of the priorities of the Uzbek cotton industry is to increase its competitiveness in the regional and world market through the production of promising varieties of cotton, increasing its competitiveness in the world market and the development of high-quality
fiber, the Cabinet of Ministers, the main directions of government reform include promising new fiber I, the Creation of medium-thin fiber varieties III, IV and B-forms, their content in the territories of regions, regions, districts, as well as farms and development of complexes, due to the introduction of a new quality of imported cotton, reduce total price [1].
Water quality standards (NPC) are the main criteria for determining the intensity, growth, development, harvest, quality of cotton fiber, the efficiency of fertilizer application in water and the efficiency of fertilizer application through water using high-quality yields of medium-thin grades of fibrous cotton through improved irrigation procedures. To reduce water consumption for cotton crops, the optimal planting thickness of each hectare is based on soil types, groundwater levels depending on regions, regions, provinces, districts, farmers. requires training; Dependence on the genetic and physiological characteristics of cotton varieties and non-compliance with the above-mentioned optimistic principles, which have a negative impact on the yield of new varieties, promising seed varieties that give high-quality yields, studied by many experts, scientists, varieties, Maintenance of new varieties. Development and implementation of agro-industrial complex system based on existing natural, soil, reclamation and hydrogeological conditions. The most important and important factor in our perception is the need for soil, the condition of plants, which is understood by experts in all fields. Based on the above, it is essential to study the norms S-6524 (default), Bukhara-102, water nutrition norms (NPC) and irrigation procedures in typical rough soils that occupy a certain area of the country's soil. that's one of the problems.
The aim of this study was to study variations of cotton seeds in S-6524 (default), in cotton seeds of IV-V type "Bukhara-102" on typical gray soils, as well as in the thickness of water fertilizer seedlings (NPK) [2]. C) in the study of the norms and rules of irrigation systems, growth and development of different varieties of cotton, yield. (Table 1.)

The experiment was divided into 7 variants, 4 repetitions, one half. Each line has a width of 8 rows - 4.8 m, a width of 60 cm, an area of 384 sq. M, including an area of 192 sq. M, 4 rows with a width of 2.4 meters and a length of 100 meters.
Varieties of experimental varieties were determined in the system 60h15h1-2, the number of theoretical seedlings is 80-100 thousand Tup / ha.
Field practice S6524 (control), Bukhara-102, cotton varieties in a single system, where soil moisture is 65-65-65%, 70-70-65%, 75-75-65% humidity and two types of fertilizers; H-180-220, P-130-160, K-90-110 kg / ha. As control was used S6524 option, the option 2, 3, 4, 5, 6, 7, breed Bukhara. (Table 2).

The following types of fertilizers were used: ammonium nitrate (N-34.0%), ammophos
(N-12%, R2O5 -46%) and potassium chlorine (K2O-56%). Annual standards for nitrogen
fertilizers were used based on the content of nitrogen in monoammonium phosphate.
