In the article presents results of analysis of inheritance and variability of some agronomic valuable traits in hybrids obtained with participation of cotton varieties that differ sharply in origin. Studied plants Ғ1, it was found that complete dominance of unlimited type of branching in Ғ1, effect of heterosis, complete dominance and intermediate inheritance depending on the genotype of the parental forms according to traits of precocity and weight of 1000 seeds. In the inheritance of fiber length in F2 hybrids, a wide range of variability was revealed and a markedly high variability in interspecific hybrids compared to simple hybrids. From F3Sultan x Surkhan-14 combination were selected and recommended families for breeding.

The irrigated soils scattered in the Khorezm oasis on the lower shore of Amudarya have great potential in the agriculture of our republic. Therefore, the creation of a system of measures aimed at preserving and protecting them, increasing production capacity and productivity, and improving land reclamation is one of the most important current issues of today.

At present, research and development activities aimed at developing new scientific and technical solutions for the effective use of land resources, the organization of optimal use of agricultural land in areas affected by erosion and at risk of erosion in land development projects are being carried out. In this direction, among other things, reducing the harmful effects of the environment in areas with the risk of water and wind erosion, improving the methods of effective use of each plot of land, taking into account the natural and economic conditions and the requirements for the protection of land from erosion, geosystem complexes that allow to prevent erosion in land formation. development, efficient use of land, protection of soils from erosion, creation of technologies that allow to increase the productivity of land is considered urgent. In this regard, special attention is paid to studies aimed at improving the efficiency of work in determining the composition of land types attached to land users and methods aimed at their optimization. Based on this, the main task of today's region is the wide use of modern economical technologies and the possibilities of their application to production, analysis of problem solving, and elimination of excess costs.

Soil properties can vary to some extent depending on the geomorphological conditions in which they are located. This is due to the diversity of parent rocks, layering and mechanical composition of the soil. The article presents and compares the properties of irrigated gray-meadow, meadow and marsh-meadow soils located on terraces I, II, III of the Syrdarya River. Based on the results obtained, recommendations are given for the rational placement of plants.

Studies have been carried out on the processing of melon products in the primary seed production of melon crops on the basis of German and local technology. As a result, the yield of dried melon products from Sakhovat variety was 20,2%, Zar gulobi variety 12,6% and Suyunchi 2 variety 13,6%. “Melon jam” is prepared from melon fruits. From 1 ton of melon fruits, 1,6 tons of jam were obtained.

Asparagus, better known as asparagus, is a perennial that grows mainly in dry climates. There are about 100 types of asparagus, but some sources mention the presence of 300 types of asparagus. Asparagus, which is familiar to many, has a high taste, which is grown in the form of a shrub or grass. The upper part of the young shoots of this vegetable is included in various culinary delights. However, only 20 types of asparagus are suitable for food. The article notes the nutritional and healing properties, how to use them, and provides information on the history of asparagus and chemical composition. A brief morphological characteristic of asparagus, its relation to environmental factors is given. The technology of growing asparagus is described in detail: seed preparation for sowing, site selection, soil preparation, fertilizers, methods of growing crops, care and harvesting measures.

The observations gave the following results, it is known that the number of seedlings per unit area is more or less, the number of ribbons in the tape and the distance between plants in the tape is short (5 cm) or wide (10 cm) caused the error amount to vary. The reason for the decrease in productivity from the small feeding area to the large feeding area was directly related to the number of plants per unit area. If onion sprouts are planted in a two- and three-row tape method, the amount of onion heads in the crop is 92,1% to 93,8%; It was found to be in the range of 86,4 percent to 89,9 percent. Among the studied planting schemes, the highest and highest-quality yield per hectare was obtained from options planted in three rows, the distance between strips was 15 cm, and seedlings were planted in the strip at a distance of 5 and 7,5 cm (44,8; 38,7 t/ha).
观察得到如下结果，我们知道单位面积的幼苗数有多有少，胶带上的条带数和胶带上植株之间的距离有短(5厘米)或宽(10厘米)导致误差量的变化。从小采食区到大采食区生产力下降的原因与单位面积的株数有直接关系。如果采用二行和三行带法种植洋葱芽，则作物中洋葱头的数量为92.1% ~ 93.3%;调查发现，这一比例在86.4%至89.9%之间。在研究的种植方案中，每公顷产量最高和质量最高的是3行种植，条带间距为15 cm，幼苗种植间距为5和7,5 cm (44,8;38岁的7吨/公顷)。
