karim as a new line (hamam-4: t.aest/sprw's'//ca8055/3/bacanora86 icw92-0477-1ap-1ap-4ap-1ap-0ap) was evaluated at gachsaran agricultural research station in 2004-2005. it was selected for its high grain yield (3975 kg ha-1) and included in advance yield trial in gachsaran, khoramabad, gonbad, moghan and ilam field stations in next growing season. average yield of this line and check ...

among crop plants, corn (zea mays l.) need a great amount of nitrogen during its growth period. an increase in the efficiency of nitrogen application not only decrease environmental pollutions, but also it,s economical. this study was conducted to determine the effect of nitrogen fertilization management on the yield and nitrogen efficiency in corn during 2006-2009 at safi-abad dezful agricultu...

soil salinity is a serious problem in south khouzestan province. this study was conducted in shawoor agricultural research station, north of the city of ahwaz, on silty-clay soil with 8 dsm-1 salinity during 2006 and 2007. a completely randomized block design arranged in split plots with three replications was used. the plots (planting methods) were: broadcasting + disk harrow (p1), broadcastin...

scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

a field experiment was conducted during 2003-4, 2004-5 cropping seasons evalute the effects of plant density on growth and yield of different rapeseed cultivars. the study was carried out at ramin agriculture and natural resources university (35 km from northeast of ahwaz). the experiment was in the form of split plots' based upon a complete randomized block design of four replications. ma...

We estimated the genetic gains of the 12th cycle of reciprocal recurrent selection for maize traits of agronomic interest. We used 23 ISSR molecular markers in an attempt to maximize genetic variability among and within populations based on selection of S(1) progenies. To this end, 138 full-sib families were evaluated in a randomized block design in two environments (the municipalities of...

in order to evaluate the delay cropping on yield and yield component of two canola cultivars and selecting the best genotype and row spacing, an experiment was conducted at three years (2007, 2008 and 2009) in gorgan research station. this experiment was arranged in spilt-factorial based on randomized complete block design with four sowing dates (28 oct., 12 and 28 nov. and 12 dec.) as main plo...
