This study explored the intelligent impacts of different paces of Defalcation flooding and timings of N application on wheat and grain yields since there was no report on this important subject. Field tests in strip-plot styles double-dealing mechanical gadget line sources were led for a long time at a steppe Mediterranean site. In every years, there was a major water system by-N collaboration on wheat grain yield anyway not on grain. synthetic component application at stem lengthening and heading conjointly gave the best grain N content. The presence of communication in view of water system by-timing of N application in wheat anyway not in grain likely could be because of wheat includes a higher N take-up while blossoming anyway lower compound component remobilization power than grain. Results taught that wheat ranchers higher apply N at stem prolongation and heading for an improved yield and grain N content except if they're not flooding or inundate with least amount of water.

This article discusses inheritance of growth duration in domestic and interspecific f1 plants. Scientists have noted that the shorter and more compact the height of the cotton plant, the higher the number of seedlings, the better the flowering and ripening levels, as well as in some hybrid combinations, the character of early maturity of cotton has a weak and moderate correlation with the character of plant height.

This article contains a lot of information about the types of soil distributed in the territory of Uzbekistan and their morphological, anatomical, physiological characteristics. Soil is formed from various rocks on the surface of the earth as a result of the interaction of various natural factors and living organisms under certain conditions.

This article talks about the emergence of engineering, its development, its role in commerce, the creation of various plant varieties, the introduction of a new era of science in Uzbekistan, and the achievement of significant results in this regard.

Taking into account the properties of fertilizers and their interaction with the soil, creating favorable conditions for plant nutrition and the most effective rates, methods, periods and ratios of fertilizer application for specific soil and climate conditions. definition is important. Plants need all the nutrients to get a high and quality harvest. They are in the form of organic and mineral compounds in the soil.

The article provides information on the dependence of such indicators of productivity as the number of bolls, the yield of cotton from one boll and the yield of one boll for various varieties and samples of fine-staple cotton on low-nutrient desert sandy soils of the river. Termez district of Surkhandarya region on the biology of varieties.
