Over the past two years, decrease in potato yield has been observed Moscow region. One of main reasons is unfavorable weather conditions. To obtain a guaranteed yield, as well to improve quality products, it necessary carry out reclamation works, including additional irrigation. Creation optimal water - air balance plant throughout entire growing season will increase productivity, and agricultu...
In order to study the effect of depth of drip placement in soil in subsurface drip irrigation, and fertilization time during irrigation events, on tuber yield of potato, an experiment was carried out in Jiroft area in 1389. This experiment was in a completely randomized block design with four replications, with depth placement of drip tape as the main plot, and fertilization time as the sub-plo...
Abstract Conventional irrigation methods to new have been altered with respect reduction of water resources and climate change. Considering the corn cultivation development, applying modern namely drip aim improving efficiency consumption as well zone under has investigated. In this research, performance (SC 704) in various managements (by strip method) both single-row double-row planting patte...
Subsurface drip irrigation (SDI) applies water directly to the crop root zone using buried polyethy lene tubing, also known as a dripline, dripperline, or drip tape (Figure 1). Driplines come in varying diam eters and thicknesses in order to maintain acceptable irrigation uniformity for different field lengths. Smaller diameter driplines are used when short lateral lengths are required. As la...
for continues production if field crops in arid and semi arid regions of the world, such as iran, beside of using of drought resistant varieties, water management must also be considered. in this context, the use of tape drip irrigation system could reduce the amount of irrigation water consumption. this study, was conducted to determine the best sowing pattern of sugar beet under type drip irr...
Location of soil moisture sampling in irrigation management is of special importance due to the spatial variability of soil hydraulic characteristics and the development of root system. The objective of this study was determination of the suitable location for soil moisture sampling in drip-tape irrigation management, which is representative of the average moisture in the soil profile (θavg) as...
this study was performed to investigate the effect of different levels of irrigation water applied in tape drip irrigation on yield, seed yield components, oil yield, seed oil percent, and seed water use efficiency (wue) of two canola varieties in behbahan agriculture research station in 2009 and 2010 seasons. the experiment was performed in split plots as a randomized complete block design wit...
Subsurface drip irrigation systems, compared to other irrigation systems (basin and furrow), enhance the delivery of water and nutrients directly into the root zone. The purposes of this study were to determine wetting front advancement in a subsurface drip irrigation and to compare the results with the HYDRUS 2D model simulation. In this study, the irrigation using T-Tape was carried out on a ...
Aim of study: To investigate how the cross section a drip-irrigation tape affects local head loss.Area The work was carried out in laboratory Irrigation hydraulics, College Water Conservancy and Environment, Three Gorges University, Yichang, Hubei province.Material methods: Tapes with six different wall thicknesses were studied experimentally to determine relationship between cross-section defo...
Use of drip, or trickle, irrigation in agriculture has increased rapidly during the past 20 years. In 1970 approximately 50,000 ha in the United States were under drip irrigation, by 1985 the area had increased to over 300,000 ha (6). Irrigation has been used to deliver fertilizers and pesticides (8,9,14,18,27,28), and there are increasing numbers of studies on the application of nematicidal co...
