| Abstract | ||
| To study the effect of some plant extractions and vitamin C on bread wheat yield . Its components and other characters. Afield experiment was conducted during growing season of 2009 - 2010 at the Experimental Farm , Department of Field crop Science , College of Agriculture , University of Baghdad .Randomized complete block design with three replications was used in split plots arrangement , main plots included five cultivars of wheat (Mexipak , Abu-Graib-3 , IPA 99 , IPA 95 and Fatah) while subplot included vitamine C at concentration 1.5 mg.L¯¹ , karkade at 50% and liquorices concentration at 25% in addition to control treatment which sprayed with distill water . Spraying with extractions and vitamin C was done twice, the first at tillering and the second booting stage. The results indicated that IPA 99 cultivar was superior in total yield (9.6 ton.ha-1) due to its highest number of spikelets / spike (23.75),number of grains/ spike(80 grain)and weight of 1000 grain,(38. 32 gm).Treatment with karkade extraction lead to significant increase in grain yield (10.32 ton.ha-1 ) due to the highest number of grains / spike(77.5 grain ) ,number of spikelets/spike (22.07) , spike length (13.11 cm), number of tillers.m-2(239.7) and number of active tillers.m-2 (192.9 spike.m-2). | ||
