Due to the competition for water resources, increasing efforts are done in order to use more efficiently irrigation water in agriculture. The purpose of this paper is to find out daily soil water content (SWC) dynamics during depletion cycles in order to emphasize its pattern and compare daylight vs. night (dark) and morning vs. afternoon SWC dynamics in an irrigated peach (Prunus persica [L.] ...

Climate change alters the abiotic constraints faced by plants, including increasing temperature and water stress. These changes may affect flower development and production of flower rewards, thus altering plant-pollinator interactions. Here, we investigated the consequences of increased temperature and water stress on plant growth, floral biology, flower-reward production, and insect visitatio...

The underlying influences of soil flooding, pH level and soil-inhabiting Diaprepes abbreviatus (L.) root weevil larval feeding in citrus were examined in two separate greenhouse studies, rootstock flooding Diaprepes-larvae (RFD) and liming rootstock flooding Diaprepes-larvae (LRFD). Our objectives were to determine the combined effects of soil flooding and pH level on survival and growth of Dia...

Initial Cadmium (Cd) isotope fractionation studies in cereals ascribed the retention of Cd and its light isotopes to binding sulfur (S). To better understand relation S soils plants, we combined XAS speciation analyses soil-rice systems that were rich S. The included distinct water management (flooded vs. non-flooded) rice accessions with (excluder) without (non-excluder) functional membrane tr...

throughout the present study some vegetative and reproductive characteristics of rosa damascene fewer than three different irrigation regimes (100, 70 and 40% of potential evapotranspiration) through an application of surface vs subsurface drip irrigation systems were investigated. some morphological characteristics investigated, included the number of branches per plant, shading diameter, plan...

Drought affects yield of peanut, but its effect on oleic and linoleic acids that influence its oil quality of peanut genotypes with different levels of drought resistance has not been clearly investigated. Therefore, the aims of this research were to determine whether soil water levels could affect oil quality by changes in fatty acid compositions of peanut, and to investigate the changes i...

Water extraction from floodplain river systems may alter patterns of inundation of adjacent wetlands and lead to loss of aquatic biodiversity. Water reaching the Okavango Delta (Delta), Botswana, may decrease due to excessive water extraction and climate change. However, due to poor understanding of the link between inundation of wetlands and biological responses, it is difficult to assess the ...

In flooded and non-flooded impounded forests of Black mangrove (Avicennia germinans), the community structure of the ammonia-oxidizing betaproteobacteria (β-AOB) differed among distinct mangrove vegetation cover types and hydrological regimes. This had been explained by a differential response of lineages of β-AOB to the prevailing soil conditions that included increased levels of moisture and ...

This study compared the impact and uptake of root-administered CeO2 nanoparticles (NPs) in rice growing under flooded aerobic soil conditions, which are two water regimes commonly used for cultivation. NPs at 100 mg/kg improved photosynthesis plant growth by reducing oxidative damage enhancing tolerance to stress, while a higher concentration (500 mg/kg) negatively affected growth. More signifi...

concerning limitation of water resources, determination of the least water that can lead to the maximum yield is of great importance in crop production. in order to evaluate effects of deficit irrigation on grain yield and water use efficiency of some wheat )triticum aestivum) cultivars under different climatic conditions, two similar field experiments were conducted in 2004 in agricultural res...
