crucial for the survival of agriculture in northeastern Colorado. Improper N and irrigation management are major factors contribThe relationships of corn yield and nitrate leaching uting to water quality and shortage problems in the Great Plains. with irrigation, N fertilization, and plant population This study was conducted on the Irrigation Research Farm in Yuma, have been extensively investi...

The review analysis of twenty two irrigation efficiency (IE) studies carried out in the Ebro River Basin shows that IE is low (average IE)(avg)(= 53%) in surface-irrigated areas with high-permeable and shallow soils inadequate for this irrigation system, high (IE)(avg)(= 79%) in surface-irrigated areas with appropriate soils for this system, and very high (IE)(avg)(= 94%) in modern, automated a...

Machinery for sowing wheat directly into rice residues has become more common in the rice-wheat systems of the north-west Indo-Gangetic Plains of South Asia, with increasing numbers of farmers now potentially able to access the benefits of residue retention. However, surface residue retention affects soil water and temperature dynamics, thus the optimum sowing date and irrigation management for...

abstract in order to investigate the effect of irrigation and nitrogen fertilizer, on yield peanut plant, with furrow method of irrigation and water use efficiency (wue) in management to create a proper and better production, split plot experiment was over taken as in complete randomize blocks with three replications and main plot with 6, 12 and 18 day interval irrigation and no irrigation and ...

The North China Plain is one of the most important grain production regions in China, but is facing serious water shortages. To achieve a balance between water use and the need for food self-sufficiency, new water efficient irrigation strategies need to be developed that balance water use with farmer net return. The Crop Environment Resource Synthesis Wheat (CERES-Wheat model) was calibrated an...

Evaluation of irrigation system performance facilitates objective analysis of the typical as opposed to the potential performance of various types of irrigation systems and the respective management criteria, appropriate for local conditions. This information can also help with the selection of one system over another given local constraints. The impact that the application uniformity of a syst...

Inflammatory Myofibroblastic Tumour (IMT) or ‘pseudotumour’ of the kidney is a uncommon benign tumour, common in young adults with unknown etiology. Clinical feature and radiological investigations are usually inconclusive. Often, biopsy inconclusive required management similar to that Renal Cell Cancer (RCC). Diagnosis based on immunohistochemistry. We reporting case IMT 32-year-old female pat...

In developing Asian countries, a major recent change in irrigation management is the rapid spread of private pumps and wells (modern irrigation systems). This process was accelerated by the introduction of the hydraulic drilling method in the 1980s and further by the development of the pump industry in China and India in the 1990s. The spread of modern systems is associated with the decline in ...
