Available water resources for agricultural irrigation have decreased worldwide in recent decades, prompting advances in water saving methods. In this study, soil water regime and water balance in a transplanted rice field with reduced irrigation (multiple shallow depth irrigations) in the Taihu Lake Basin of East China were observed and then evaluated using Hydrus-1D model during two consecutiv...

a field experiment was conducted to study the spatial relationships between weed seed bank and population and their distribution models in sugar beet crop (beta vulgaris) in 2009 at motahari  agricultural research station of karaj. sampling from seed bank before sugar beet drilling and weed population in three stages during the growing season were done using square (50*50 cm) and rectangle (25*...

Representations of femininity in video games and other media are often discussed with reference to the most popular games, their protagonists and their sexist predicament. This framing leaves in shadow other dimensions. We aim to identify some of them and to open a broader horizon for examining and designing femininity and gender in games. To this end we look into games with creative portrayals...

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

to evaluate growth characteristics and adaptation of new asian pear cultivars (pyrus serotina rehd.) in iran, some growth characteristics and physiological factors of nine asian pear cultivars named ‘ks’6, ‘ks’7, ‘ks’8, ‘ks’9, ‘ks’10, ‘ks’11, ‘ks’12, ‘ks’13, ‘ks’14 and one european, present commercial cultivar ‘shahmiveh’ of iran (control) were evaluated under the climatic conditions of tehran ...

Understanding the impact of a pest species on a particular crop is critical for the success of a pest management program. Field studies were conducted to determine the effect of the twospotted spider mite, Tetranychus urticae Koch, on marketable yield of strawberries during the 2008/2009 and 2009/2010 growing seasons. Low, medium, and high mite infestation levels were established by initial ino...

we estimated the rainfall interception loss (i), canopy storage capacity (s), the ratio of mean evaporation rate from the wet canopy () over the mean rainfall intensity () (mm h-1) (), and free throughfall coefficient (p) in a fraxinus rotundifolia mill. stand located in an afforested park land in a semiarid region of iran. for each storm event, i was calculated as the gross rainfall (gr) minus...
