A field experiment was conducted during 2001-2003 to evaluate the effect of water stress on the yield and yield components of four rice cultivars commonly grown in Mazandaran province, Iran. In northern Iran irrigated lowland rice usually experiences water deficit during the growing season include of land preparation time, planting, tillering stage, flowering and grain filing period. Recently d...

this study aimed at determining the efficiency of sugar beet growers in borujerd city, iran. data were collected from 2010-11 growing season by random sampling of sugar beet growers and filling 100 questionnaires and analyzed using data envelopment analysis (dea) method. results showed that the average technical, economical and special efficiencies were 0.83, 0.79, and 0.84 in fixed output stat...

Drought is the most significant constraint for crop production in arid and semi-arid regions. In order to assess drought tolerance in fifteen rapeseed (Brassica napus) cultivars using yield-based drought tolerance indices, two experiments were conducted at the research station of College of Agriculture, Shiraz University, Shiraz, Iran during 2009-2010 growing season. The cultivars were...

Scaling-up knowledge of land-atmosphere net ecosystem exchange (NEE) from a single experimental site to numerous perennial grass fields in the Northern Great Plains (NGP) requires appropriate scaling protocols. We addressed this problem using synoptic data available from the Landsat sensor for 10 growing seasons (April 15 to September 30) over a North Dakota field-site, where we continuously me...
