Abstract: This research was conducted to investigate the effect of sowing date on growth and yield of five rapeseed (Brassica napus L.) cultivars. The experimental design consisted of four randomized complete blocks (CRDB) in a split-plot arrangement. Four convetional sowing dates (11 September, 27 September, 12 October and 27 October) as main plots and five rapeseed cultivars (RGS00...
In order to investigate the effect of sugar plant effluent on shoot solute percentage, yield components and grain yield of two wheat cultivars, a two year field experiment was conducted on a farm near Eghlid sugar plant during 2004-2005. Treatments consisted of two wheat cultivars (Alamot and Zarin) and two irrigated treatment: irrigation with effluent and irrigation with spring water (control)...
To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...
an experiment was conducted to determine the effect of five plants densities (100,200,300,400 and 500 grain m-2) on yield and its components in three rain fed barley cultivars (ezeh, mahor and dopar). a factorial experiment based on randomized complete block design with three replications was conducted in agricultural research center of khorramabad city in the east of iran (in 2006-2007). in th...
The efficiency of a breeding program depends mainly on the direction of the correlation between yield and its components and the relative importance of each component involved in contributing to seed yield. The objective of this study was to detection of traits affecting canola yield by multivariate analysis, at Khozestan Province, Iran, in the agricultural year in 2015–2016. A randomized compl...
to evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in islamic azad university agricultural research station, isfahan, as a split plot in a randomized complete block design. main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...
A diallel analysis of eight bread wheat (Ttriticum aestivum L.) cultivars was conducted to determine genetic parameters and the type of genetic control for yield and yield components. The parents and their F1 hybrids were evaluated in a randomized complete block design with 3 replications. General and specific combining ability effects were estimated by the method 2 of the Griffings model I, an...

Breeding new crop cultivars with efficient root systems carries great potential to enhance resource use efficiency, plant adaptation to unstable climates and improve yields. Current study was conducted to investigate the relationship between root characteristics with yield and yield components in 24 lines and cultivar of bread wheat using complete randomized block design with three replications...
water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...
