this study was carried out in order to identify the effects of soil water depletion (swd) on monogerm sugar beet (cv. shirin) seed growth trend at different growth stages. an experiment was conducted in randomized complete block design (rcbd) with three replications in ardebil agricultural research station. during 2002 and 2003 cropping seasons, nine treatments including control (irrigation aft...

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...

in order to evaluate the possibility and compare different irrigation methods in ricecultivation, an experiment was conducted in factorial based randomized complete blockdesign at rice research institute of iran, mazandaran (amol), during 2011. treatments weredifferent irrigation regimes including alternate wet and drying (awd), semi-dry cultivation(sdc), combining shallow water depth with wett...

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.] ...

Survival, germination, olive colonization, and water-use efficiency (WUE) impairments by Verticillium dahliae could be influenced cultivar susceptibility or irrigation, this modify the irrigation–pathogen–disease relationship. In study, combined effects of irrigation on wilt (VW) development were modelled temporary assessment V. propagules (total inoculum density, density micropropagules, scler...

Spring and summer tillage are usually followed by irrigation before planting crops in California's summer-dry Mediterranean-type climate. Tillage treatments such as rototillage or disking are known to disturb the soil structure to different extents, but little is known about how the intensity of a tillage event and subsequent irrigation affect the microbial biomass, respiration, CO2 efflux, and...

Variation in plant quality and natural enemy abundance plays an important role in insect population dynamics. In manipulative field studies, we evaluated the impact of varying irrigation levels and insecticide type on densities of Lygus hesperus Knight and the arthropod predator community in cotton. Three watering levels were established via irrigations timed according to three levels of percen...
