recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...

Biochemical and physiological traits are affected by environmental stresses and therefore the breeding of these traits will play an effective role in stress tolerance. In this study, hybrids of five S7 lines of maize in a 5 × 5 half-diallel design were investigated in order to study the combining ability of biochemical and physiological traits of maize at the Research Farm of Graduate Universit...

Water deficit is one of the most important environment tensions that reduce plant growth. The present experiment was conducted based on split plots based on complete randomized blocks design with three replications during 2019 cropping year at Moghan Agricultural Research Station. Two levels of irrigations as regular irrigation and irrigation cut in the seedling stage (irrigation cut applied du...

In order to investigate the response different of maize hybrids under drought stress in different levels growth stages, a field experiment was done as split plot layout based on randomized complete block design with three replications, in crop school of Meghan of Agriculture and natural Resources in year 2014. The treatments were included three irrigation regimes (Full irrigation, deficit irrig...

In order to investigate the effect of nitrogen management on morphophysiological traits, yield and yield components of corn hybrids, the present experiment was carried out in a split plots arrangement in a randomized complete blocks design with three replications in a field located in Ahvaz city during the crop year 2016-2017. Experimental treatments consisted of nitrogen fertilizer management ...

In order to evaluate the suitability of maize hybrids in different planting dates, an experiment was conducted as split plot in JalilAbad, Varamin, Iran in 2015. Main and sub plots were planting date (D1: April 4, D2: April 19, D3: May 5, D4: May 20) and maize hybrids (H1: Gazda, H2: Maxima, H3: KSC 701, H4: AS160) respectively. Results indicated that there was variation between hybrids in term...
