This article provides data on the inheritance of fiber yield and fiber length in first generation hybrid forms derived from genotypically different forms of G.hirsitum L species medium fiber cotton. The obtained results showed that in hybrids F1 dominance of one of the parent forms and intermediate inhe¬ritance by the characteristics of yield and length of fibre is manifested in hybrids of forms with different ge¬notype, with high and medium index, and inheritance by the type of positive superdomination, i.e. positive heterosis - in hybrids of forms with medium and high index.

The results of the study revealed that the mismatch intensity rain rate of water absorption into the soil formation of a surface relief and soil erosion, uneven and shallow soaking imperfection open irrigation system at a superficial irrigation, the need for different irrigation methods in the growing and not growing periods, low coefficient land utilization, high cost of irrigation and other features are, to a certain extent in conflict with the requirements of watering cultivated with techniques for / of crops in an area at the deep groundwater. The necessity of different methods of irrigation in different periods of the growing season of plants has been substantiated. Low land utilization rate, high cost of irrigation and other features that contradict the requirements of irrigation cultivated using methods of growing crops in the area of deep groundwater are indicated.

This article provides information about planting, propagation of medicinal Crocus, determining the cultivated area, depending on conditions, various harmful insects.The article shows that Crocus damages winter scoops, gamma scoops, spider mites, bedbugs, aphids and thrips, especially bed bugs and spider mites, do more harm than others.It is also noted that the implementation of agreed measures against them is a guarantee of a high and quality crop.

It is aimed at studying the influence of certain types of plant extracts " Unabi "(zizifus) and" Karolina " (kaspiyskaya) on the rheological properties of wheat dough in the technology of making national tortillas.

Object of research here were plant extracts obtained by extraction of the aboveground part of the plants "Unabi" and "Karolina", as well as some assortment of national bakery products. Uzbek tortillas were chosen as national bakery products.

The formation of the appropriate, effective and effective mechanism of the restoration of irrigated lands in the state of degradation in the conditions of diversification of land use in our country is one of the most important problems of today. In this sense, this article presents the results of research on the restoration of irrigated lands in the state of degradation and their return to the process of their use repeated and offers in this regard are presented.

Neutral lipids of oat fruits (Avena sativa L.) were studied varieties "Tashkent 1", harvested in the Samarkand region of the Republic of Uzbekistan. The study of the component composition of neutral oat lipids by TLC showed that they consist mainly of triacylglycerides and free FA, which were accompanied by hydrocarbons, phytosterols, triterpenoids, and Tocopherols. The study of the effect of heat and salt stress on the growth of wheat seedlings during pre-sowing treatment of wheat seeds with unsaponifiable substances of oat grain lipids showed that unsaponifiable substances of the studied object's lipids at a concentration of 0.0001% have a protective activity.

Standards that define the quality of seeds of agricultural crops, along with setting certain requirements, allow the cultivation of high quality seeds and serve to introduce new varieties in objectively successful production.

The problem of the nutritional and biological value of food products, including bakery products, shows the feasibility of improving their chemical composition, eliminating the deficiency of individual components, enrichment with high-grade proteins, vitamins, minerals and dietary fiber. An effective way to solve this problem is to use as additives high-protein products of plant origin, in particular, obtained by extracting the ground parts of certain species of non-traditional plant species.

The article deals with the timing of reproduction, methods of reproduction, productivity, growth and development of offspring, biological, tribal features of meat and wool sheep in Uzbekistan. In order to increase the competitiveness of sheep breeding in Uzbekistan, using the best global gene pool, a new breed group of sheep with meat and wool productivity (Uzbek meat and wool sheep) has been bred. The introduction of meat and wool sheep into the practice of artificial insemination by frozen sheep seeds characteristic of the world sheep gene pool showed that the live weight of lambs taken from them, compared with the live weight of lambs obtained from natural insemination, was higher-0.4 kg (9.3%), at 10-day-0.5 kg (6.8%) and 3-month-old age-0.4 kg (1.3%).

The article identifies the development of bugs, their biological properties, and the presence of more than 10 species of natural enemies, which reduce their number in the agrobiocenosis of seed orchards. 24% of Spiromectin vaccines (0,25 ha/l), 50% n.p. (0,33 ha/l), Universal 25% s.g. (0,2 ha/l) insectoacaracids were tested against bugs, and as a androgen variant, Himgold had 72% em. (1,0 ha/l.) drug was selected. Chemicals have been found to reduce the number of phytophagous bugs and their natural enemies. According to the results of the experiments, all insectoacaricides, except for the Universal 25% s.d.g., were highly effective against spidermites.

Study was directed to decide the impacts of use of osmotic solution on germination of pea seeds
(Pisum sativum L). Trial was organized under totally randomized structure with three duplicates. This
examination was led in germination bureau at , Cukurova University, turkey during February-May 2020.
Seeds were prepared in different osmotic capability of polyethylene glycol-6000 (- 0.3, - 0.6, - 0.9 and
- 1.2 MPa) and refined water (2.5 µs/cm) at 20 0C for 24 hours and there was likewise a control
treatment. In this investigation, 3 pea cultivars (Utrillo, Carina and Rondo) were utilized and
germination tests were done in dull conditions in a germination bureau held at 20 0C and half relative
moistness for 8 days. The useful and hurtful impacts of preparing rely upon the life form physiology
and point of this examination Use of water double the volume of seed and Use of osmotic solution
consequences for germination in pea (Pisum sativum L.) seeds. Seedling length, germination rate,
energy file esteems fluctuated between medicines 1.32-5.85cm, 48.33-86.39% and 73.54-543.89,

This article indicates that farmers and clusters of the republic need to pay special attention to sowing qualities when preparing seed material. Currently used standards do not meet current requirements, where they offer solutions to this problem.

As a result of the erosion process, most of the mountainous and foothill areas of the country have lost their fertility. The need for comprehensive control measures to restore lost fertility is as important as the demand of the day, and its scientific and economic effectiveness is determined. For this purpose, the soil vegetation of the natural zones, climatic conditions and ecological conditions of the landscapes were studied and analyzed based on the results of the monitoring. In the example of Gusar region, the object of research was selected and cuts were made, and the corresponding field-soil-erosion study was carried out. Analytical laboratory researches were carried out on soil samples taken in the area and the results were analyzed. Based on the results of the comparative analysis, it was determined that these gray-brown soil types, which are widespread in the area, are mostly eroded to a moderate degree. The fertility of these lands has been lost and productivity has declined. In the process of soil erosion in the mountainous and foothill regions of the country, many of them have lost their productivity. It is recommended to take comprehensive measures to restore soil fertility. To this end, it is necessary to have the honor of climatic conditions, vegetation landscapes and other natural ecological aspects.
