| dc.description | The level of water supply during the cultivation of soybean as a repeated crop was positive when the soil moisture before irrigation was 70-80-80 in all irrigation methods. However, excessive water supply increased the plant height (88.6 cm at the ripening stage) and the tendency to lie down. Based on the results of a three-year average analysis , the use of modern agrotechnologies that save water resources in the cultivation of soybean as a repeated crop, namely drip irrigation in agronomic conditions with a pre-irrigation soil moisture ratio of 70-75-75 per repeated soybean plant height (13.9; 35.8; 53.3; 73.1 cm), was found to be the optimal irrigation method compared to other agronomic and pre-irrigation soil moisture options. | en_US |

Soya o‘simligi o‘sishi va rivojlanishi, hosildorligi ob-havo va iqlim sharoitlari qarotida qo‘llaniladigan agrotexnik tadbirlarga bog‘liq bo‘lib, sutkalik suv sarfi soyaning o‘sish fazalariga bog‘liq holda bo‘lib, maksimal suv sarfi dukkaklarni shakillanish fazasidakuzatilgan. Soya yetishtirish davrida oziqa moddalar bilan va suv bilan ta’minlanganlik darajasi o‘sish va rivojlanishni cheklovchi omillar sanaladi | en_US |
| dc.description.sponsorship | Many scientists believe that irrigation standards are one of the factors that significantly affect the growth, development, and productivity of plants grown in agriculture, and that changes in irrigation regimes result in changes in plant height, number of leaves, branches, and yield elements [1; p. 433, 2; p. 136, 3; p. 51-55, 5; p. 17-22]. that in determinant varieties, the number of bushes increased , that is, when there were up to 70 plants per 1 m 2 , the height of the Ros' variety, with a number of bushes of 30-40 per 1 m2 , did not increase , and the plant height reached its maximum when the number of bushes per 1 m2 was increased to 70. When the number of bushes per 1 m 2 was increased to 80, 90, 100, the number of leaves and the height of the plant did not increase, but rather decreased to 2-4 [4; pp. 74-78]. According to MN L'gov, studying the irrigation regimes of soybean in the Volgagrad and Zavod'ya regions of Russia, to produce 2 t/ha of grain from soybean, the soil moisture content before irrigation in the 0.4-0.7 m layer of soil was 70-80-70% and 70-80-80% relative to the ChNS, 4516-5109 m3 /ha of water was required. Maintaining soil moisture at 80% relative to the ChNS led to an increase in relative water consumption. Daily water consumption, depending on the growth phases of soybean, was 22.7-65.9 m3 /ha, with the maximum water consumption observed in the pod formation phase (65.9 m 3 /ha) [6; S-40.]. As part of the study, based on the results of three years, the effect of irrigation methods and procedures on plant height in repeated soybean crop maintenance was studied, and phenological observations were carried out to measure plant height during the growing season 4 times (July 1; August 1; September 1; October 1). According to the data obtained, depending on the water supply conditions, the soybean plant was in the range of 8.3 - 11.7 cm during the phenological observation on July 1. The lowest result was recorded in the standard tillage option, when the soil moisture content before irrigation was 6 0-7 0 - 60 , and the soybean plant height was 8.3 cm, while the highest result was recorded in the inter-row film irrigation option , when the soil moisture content before irrigation was 7 0-7 5 - 75 , and it was found that the plant was 3.4 cm taller than the control option. | en_US |
