Water Efficient Technology Of Drip Irrigation In Intensive Gardens, F.U. Juraev, G.H. Karimov
Water Efficient Technology Of Drip Irrigation In Intensive Gardens, F.U. Juraev, G.H. Karimov
Irrigation and Melioration
The studies were carried out in 2017-2019 at the Zodabek farm on a 6 hectare garden plot with seedlings of half-tall apple trees “Golden Delicious”. Experimental research work was carried out at a groundwater level in the experimental area of 1.5-2.0 m, mineralization 1.0-1.2 g/l in alluvial, mechanical, medium sandy soils with the following irrigation options. The first option is irrigation, at the start of the second - drip irrigation; third, the use of specially designed soil pegs. The following results were obtained: in the control option, the average irrigation rate for three years was 1125.7 m3/ha, with drip irrigation …
Effect Of Landfill Leachates On Some Water Quality Indicators Of Selected Surface Water And Groundwater At Ilokun, Ado-Ekiti, Nigeria, Olorunwa Omofunmi, Adesola Satimehin, Abraham Oloye, Okwunna Umego

Makara Journal of Technology
This study was conducted to examine the impact of dumpsites on the quality of groundwater and surface water. The water samples and leachates were collected from dumpsites in respective zones. The physicochemical properties of the samples were examined and determined in accordance with the standards of the American Public Health Association. Results indicated that the groundwater and surface water that are close to the dumpsites have an electrical conductivity of 385 and 245 Sd/cm, total dissolved solids of 168 and 128 mg/L, a turbidity of 4.6 and 22 NTU, a total alkalinity of 103 and 50 mg/L, a total hardness …
Modeling The Impact Of Changes In The Ground Water Level On The Stability Of Agricultural Landscapes Using Gis, A.M. Arifjanov, L.N. Samiev, F.K. Babajanov, G.M. Xamdamova, Sh.N. Yusupov
Modeling The Impact Of Changes In The Ground Water Level On The Stability Of Agricultural Landscapes Using Gis, A.M. Arifjanov, L.N. Samiev, F.K. Babajanov, G.M. Xamdamova, Sh.N. Yusupov
Irrigation and Melioration
The article presents modern GIS methods for determining the stability of changes in irrigated areas and the depth of the ground water level.the most correct solutions are given in modeling this process. To distinguish agricultural landscapes, the classification of agricultural acreage in the lower part of the Amu Darya river region was made using 16-day periodic rasters 2017 of 2018 and the NDIS MOD13Q1 sensor of agricultural acreage, type NDVI. The annual change in the level of underground water in relation to the state of rivers and channels is analyzed. A steady change in agricultural acreage on the right Bank …
Relationship Between Ndvi And Hydromet Factors In Grassland Area Of Open-Pit Coal Mine, Zhang Yan, Huang Xuanming, Chen Shi, Shi Bingxing
Relationship Between Ndvi And Hydromet Factors In Grassland Area Of Open-Pit Coal Mine, Zhang Yan, Huang Xuanming, Chen Shi, Shi Bingxing
Coal Geology & Exploration
The groundwater level of an open-pit coal mine in the grassland area of the east Inner Mongolia has been decreasing continuously under the condition of long-term drainage. In order to study whether the growth of vegetation around the mining area was affected by the decline of groundwater level, the NDVI method was used to analyze the change trend of vegetation index in the study area from 2013 to 2019. Based on the joint entropy theory, the mutual information between NDVI and different meteorological and hydrological elements(temperature, rainfall and groundwater depth)were calculated, and the main influencing factors of vegetation growth were …
Apple Orchard Drip Irrigation Conditions Of The Tashkent Region Of Uzbekistan, Sardor Gulyamov, Bakir Serikbaev, Anvar Sherov
Apple Orchard Drip Irrigation Conditions Of The Tashkent Region Of Uzbekistan, Sardor Gulyamov, Bakir Serikbaev, Anvar Sherov
Irrigation and Melioration
The article presents the results of many years of theoretical experimental field research on drip irrigation of the apple orchard of the Golden variety in the conditions of the Tashkent region. Based on the analysis of climatic, soil, hydrogeological, geological, hydrological and economic conditions of the experimental plot, as well as biological features of the garden, the values of total water consumption, water consumption deficit, irrigation, irrigation rate and the number of irrigation by the bioclimatic method are determined.
