Superior upland rice varieties can be obtained through the plant breeding process. Upland lines that are carried out from crossing have different potentials. The research aims to determine promising with high yields in acid-dry land. study is conducted on Ultisol soil. first season 2019 for F 6 lines, and second 2021 7 lines. experimental methods use factorial Randomized Block Design (RBD). tre...

stem reserves of barely can be an important contributor to grain filling particularly under condition is limited such as salinity stress. the aim of this research was to study dry matter accumulation and remobilization ability in different internodes of some iranian barley varieties and promising lines under salinity and normal conditions. the research was set up as two randomized complete bloc...

effect of different amounts of foliar- and soil- applied n were evaluated in a factorial arrangement of rcbd with three replications at the agricultural research station of gorgan in 2004-2005 growing season. two promising lines of bread wheat, two levels of foliar application of nitrogen (0 and 5%) at tillering and booting stage, with five rates of 0, 45, 90, 135 and 180kg n/ha as urea were us...
