Interrelation of Performance Indicators of Technological Transport With Mining Conditions of a Quarry

Research has established that in order to obtain a high and stable yield with good taste qualities of cauliflower, it is recommended to use phosphorus of 175 kg/ha P2O5 against the background of N200 K100. At the same rates of application, ammophos is more effective than nitrocalcium phosphate fertilizer. In the article, the positive aspects of using Ammafos, Superfos, fertilizers at the rate of 175 kg per hectare in the cultivation of Cauliflower Casper F1 hybrid in the conditions of irrigated meadow-gray soil of Samarkand region, and the most optimal phosphorus nutrition norm is N200 K10 0 background Determined to be P175. From this, it was determined that the length of cauliflower heads is 14-16 cm, and the mass of cauliflower heads is 800-1100 grams.The effect of new type of phosphorus-retaining fertilizers on the growth and development, productivity and quality of the Cauliflower Casper F1 hybrid in the conditions of irrigated meadow-gray soils of Samarkand region, the effect of the phosphate component of these fertilizers on the amount of mobile phosphorus in the soil, the fractional composition of soil phosphates, and the intensity of phosphates is the first study of the researcher’s research.

et al. 2024

According to the experimental program, when we studied the effects of agrotechnical factors on the formation of vegetative and generative organs of the C-278 variety in the phases of cotton, flowering and ripening were obtained. In the ginning phase of cotton, the average weight of the above-ground part of 28-29 cm cotton was 27,7-32,6 grams. In relation to the weight of the vegetative and generative organs of the cotton, the weight of the cotton stem is 40,3-45,9 percent, and the weight of the cotton leaf is 52.9-56.4 percent, and it was observed that 1,0-5,0 percent of the weight of the cotton crop organs. In the flowering phase of cotton, the height of the plant was 57-69 cm according to the options. In the experiment, changing the preirrigation moisture of cotton had a significant effect on the formation of cotton stem mass, where the total weight of the stem, pre-irrigation moisture was 65-65-60 compared to LFMC averaged 119,0 grams under percent irrigation and averaged 140.0 grams under 70-70-60 percent irrigation compared to LFMC before irrigation.

The article presents the results of long-term research on the planting dates of the new leguminous crop Cajanus cajan in the conditions of Galaarol district of Jizzakh region and Zharkurgan of Surkhandarya region. A brief description of the biology of C.cajan, the experience of the medical field, the methods of accounting and monitoring, and the agricultural technology of cultivation were studied. Preliminary results indicate that C.cajan demonstrates a high degree of adaptability to the Uzbekiston climate, with satisfactory germination and growth rates across different regions. Nutritional analysis of the harvested seeds revealed high protein content and essential amino acids, making C.cajan a valuable addition to the local diet and a potential contributor to food security. Legumes are vital crops globally, playing a significant role in sustainable agriculture due to their ability to fix atmospheric nitrogen, which improves soil fertility and reduces the need for chemical fertilizers (Amanov et al. 1972). They are a crucial source of protein, vitamins, and minerals, making them essential for food security and nutrition.
