in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

In order to investigate the effect of treated municipal wastewater on soil chemical properties and heavy metal uptake by sorghum an experiment was carried out in the Institute of Agriculture at Zabol University, Iran 2007 in a randomized complete block design with four replications. The treatments were managed for irrigation; with well water during entire period of growing season as control (T1...

In the Midwestern U.S., perennial rhizomatous grasses (PRGs) are considered one of the most promising vegetation types to be used as a cellulosic feedstock for renewable energy production. The potential widespread use of biomass crops for renewable energy production has sparked numerous environmental concerns, including the impacts of landuse change on the hydrologic cycle. We predicted that to...

this research was carried out to evaluate the effects of some morphophysiological traits on white sugar yield of 10 commercial sugar beet (beta vulgaris l.) varieties. all experiments were conducted in four important sugar beet growing areas in iran, i.e. moghan, khoy, karaj and zarghan in 2006 and 2007. the experiment was arranged as a randomized complete block design with three replications i...

in this study, by using minimum, maximum and mean daily interpolated data from asfazari data base, the changes of agro climatic indices analyzed in iran during 1962-2004. at first, the indices calculated for each pixels and then trend and slope value evaluated by nonparametric mann-kendal and parametric regression method. in total, the results showed that the indices have positive trend on the ...

The ecohydrologic effects of urbanization that is dominated by forests clearing are not well understood in the southeastern United States. We utilized long-term monitoring data to quantify the annual water balance, stormflow characteristics, and seasonal flow patterns of an urbanized watershed (UR) (0Ð70 km2) and compared it to a fully forested watershed (FOR) (2Ð95 km2) in central North Caroli...
