abstract one of the ways to increase economic and environmental efficiency of drainage systems is water table management. water table management consists of, controlled drainage and subirrigation. this study examines the effect of controlled drainage on yield, root distribution pattern and water use efficiency of maize (sc 704) in karaj. the experiment was performed as a randomized complete des...

Less than 0.5% of total water in the world is available for human consumption and agriculture. The major part of the world's water is saline and salinity in soils interferes in germination of seeds and the posterior development of the plant. In order to increase the osmotolerance of tomato, seedlings were associated with Azospirillum brasilense Cd, Azospirillum brasilense Cd transformed bacteri...

Rice (Oryza sativa L.) is one of the major food crops in many countries. As the cultivation of rice requires huge volume of water, long term use of arsenic contaminated groundwater for irrigation may result in the increase of arsenic concentration in the agricultural soil and eventually accumulation in rice plants. Thus a micro level study was conducted to investigate the transfer of arsenic fr...

Several cultures of north-central Nigeria do not use community cemeteries. Instead, human remains are buried in and around family compounds, often in shallow and sometimes unmarked graves. At several locations, graves and drinking water wells end up too close to be presumed environmentally safe. This paper reports findings of a pilot study that explored the potential for groundwater contaminati...

the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

Drought stress is a condition that in specific climate contexts results in insufficient water availability and often limits plant productivity through perturbing development and reducing plant growth and survival. Plants use senescence of old leaves and dormancy of buds and seeds to survive extreme environmental conditions. The plant hormone ABA accumulates after drought stress, and increases p...

Fruit and vegetable processing has a significant impact on the environment due to its consumption of amount water. Water mainly depends type production technology used. in fruit plants is used as raw material, an energy carrier, hydro transport, well for washing materials maintaining hygiene. The variety technological operations carried out process seasonality make it difficult objectively asse...
