in the present study, the effects of different cadmium (cd) levels of irrigation water (0, 5, 10 and 20 mg l-1) on corn plants (foliage) under different irrigation intervals (1, 3, and 7 days) were investigated. clear cd toxicity symptoms appeared on the plants at the end of the experiment. the results showed that stem dry weight (dw) followed by transpiration (t) and plant height were the meas...

Irrigation water quality became worst in terms of increasing its salinity and causes severe problems in many cultivated crop species, resulting in lower yield. In addition, the scarcity of irrigation water due to overuse or runoff is another limitation for increasing food and feed production. Saline water treatment technology offers potential solutions; however this technology is yet expensive ...

Irrigation underpins agricultural productivity. The purpose of irrigation is to match water supply to crop water demand. The effectiveness of irrigation depends on the quality of the timing and duration of watering events, also called irrigation scheduling. Most farmers use heuristic rules to determine irrigation events. This often leads to over-watering which results in lower crop yields and w...

BACKGROUND Although the use of potable water for wound irrigation is attractive in an austere environment, its effectiveness has not been tested. We sought to compare the effectiveness of potable water irrigation in reducing bacterial number with that of normal saline irrigation. METHODS We used an established caprine model involving the creation of a reproducible complex musculoskeletal woun...

The Indian Punjab has been heralded for its technical achievements but increasingly criticized for leveraging its success on the environment. Irrigation has been one of the main pillars of the Punjab's Green Revolution. The availability of water has pushed rice and wheat productivity to new heights. Cheap water policies have enabled farmers to exploit groundwater. Water tables are shrinking in ...

Precision irrigation in fuzzy control system based on crop water stress acoustic monitoring was designed in the paper. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal irrigation and precision irrigation, which aims to both ensure normal growth of crops and achieve effective water-saving. Since five input signals affect output in different degree, t...

introduction to achieve the higher economic yield of crop plants, supplying enough nutrients to plants is very important. moreover, nutrient uptakes by plants is influenced by the soil water contents. however, nowadays chemical fertilizer application is important agronomic factor that has significant effects on growth and quantity and quality of final yield, but traditional nutrient management ...
