In the Mesilla Valley of southern New Mexico, furrow irrigation is the primary source of water for growing onions. As the demand for water increases, there will be increasing competition for this limited resource. Water management will become an essential practice used by farmers. Irrigation ef®ciency (IE) is an important factor into improving water management but so is economic return. Therefo...

To investigate genetic variation, and identification of tolerant genotypes according to quantitative indices of drought tolerance, 8 sesame genotypes were tested in a randomized complete block design with three replications under optimum and limited irrigation at the Research Station of College of Agriculture, Shiraz University. Based on the potential yield and yield under stress, quantitative ...

An experiment was conducted to evaluate the effects of different levels of nitrogen and irrigation on yield and yield components of safflower. Three nitrogen rates (0, 50 and 100 kg ha-1) under three irrigation levels (100% as control 80% as mild limited irrigation, and 60% of crop water requirement as severe limited irrigation) were investigated using a factorial laid out in a randomized comp...

A significant portion of the irrigated acreage in the intermountain western U.S. is comprised of cool season grass pastures. Droughts, coupled with increasing demands for limited water supplies in the region, have decreased the water volumes available for irrigating these pastures and other crops. Consequently, relationship between crop yield and irrigation (water production functions) should b...

BACKGROUND Postoperative infection occurs when bone graft material is dislodged into the maxillary sinus cavity and most of the patients are often uncomfortable with the drainage and irrigation procedures to eradicate the infection. In this case report, we share a technique in treating patients with such condition. MATERIAL AND METHODS A 47-year-old patient was referred after sinus elevation ...

The use of indicators for sustainability evaluation is an important step towards operationalization of the concepts of sustainability and sustainable development. Many literatures on framework for sustainable water management consider any one dimension of sustainability. In this paper, the sustainability of an irrigation system is assessed from economic and environmental dimension. An optimizat...

With uncertainty in future irrigation water availability and regulations on nutrient application amounts, experimentally determined effects of “controllable” management strategies such as nitrogen (N), water, and their combination on crop water productivity (CWP, also known as crop water use efficiency) and actual evapotranspiration (ETa) are essential. The effects of various N application rate...

Investigation of different irrigation methods on plants is necessary due to limited water resources and the increasing need for food products. The purpose of this study was to evaluate the effect of sprinkler and drip irrigation systems and hormones on morphological and physiological characteristics of potato. Treatments included sprinkler and drip irrigation systems and hormones (gibbere...

Irrigation scheduling is an important issue for crop management, in a general context of limited water resources and increasing concern about agricultural productivity. Methods to optimize crop irrigation should take into account the impact of water stress on plant growth and the water balance in the plant-soil-atmosphere system. In this article, we propose a methodology to solve the irrigation...

Extra-articular extravasation of irrigation fluid is relatively common around entry incisions and is usually limited to the subcutaneous tissue. Very rarely, extravasation occurs above the knee, in the thigh and even up into the pelvis. We are reporting the second case of irrigation fluid extravasation during a knee arthroscopy, which spread up to the thigh, groin and perineum during anterior c...
