The influence of planting times on the formation of the root system of wheat varieties in the conditions of the Zarafshan valley

Abstract

In the article, the study of the underground organs of plants is of particular importance for solving important issues related to plant biology, ensuring the proper development of crops in agriculture, the interaction of plants with the habitat in the process of growth and development, and therefore the morphological structure (shape, formation) of the root plants in different soil conditions, etc.) are characterized by extreme diversity. The formation of the above-ground mass of plants depends on the growth of the root. Therefore, in our experiment, in addition to studying the development of the wheat root system, it is aimed at studying the patterns of its growth and development, its relationship with the aboveground parts of the earth, and, finally, the influence of planting dates. on the root system of various ecological conditions of the area. In our studies, the level of development of the root system of wheat varieties depends on its penetration into the soil, the root mass, the type of soil and its mechanical composition, the topography of the sowing field, the degree of erosion, and the depth of the soil. groundwater, plant species, variety, planting dates, norms, watering, diets. It has been established that the development and activity of the root system has a significant impact on the formation of wheat varieties. The article considers the influence of sowing time on the formation of the root system of durum wheat Krupinka and soft wheat variety Krasnodarskaya 99, included in the State Register of Agricultural Crops, and recommendations are given based on the results of the experiment.
