Abstract:
A field experiment was conducted at a private field in AL - qurna site about (65) Km north of Basrah city during winter season of 2013 - 2014 in clay loam soil to study the effect of weed control methods grown in wheat fields on growth , yield characters and protein. by use three herbicides (Chevalier ,Topic and Lintur) and use two wheat cultivars (Triticum aestivum L.) (IPA - 99 and Abu - Graib). The experiment included 12 treatment came from the combination between treatments weed control and wheat cultivars .A Split - plot was used in randomized complete block design with three replicates. the main plots included wheat cultivars , while Sub - plots included treatments control.Results of the study showed that the use of Chevalier herbicide led to a significant reduction of the Broad leaves weeds reached (9.81gm m2) compared to the untreated which gave highest ratio (61.69 gm m2), and gave best inhibition ratio of weeds Broad reached (83.96%), it also excelled in giving the highest ratio for each of the number of tillers (613.67 mˉ2) , number of spikes (551.30 mˉ2) , weight of 1000 seeds ( 33.42 gm ), seed yield ( 5.70 ton hˉ¹ ) and biological yield (15.81 ton hˉ¹ ). While )Topic+Lintur( treatment herbicide was superior in plant height (89.88 cm ) , flag leaf area ( 32.98 cm2 ), spike length ( 11.57 cm ), number of seeds per spike(60.33) , harvesting index (36.06) , protein content (14.13%) and protein yield (797.98 kgm hˉ¹). and led to reduction of the dry weight of Narrow leaves weeds reached (1.77 gm m2 ) compared to the untreated which gave highest ratio (12.11 gm m2) and gave best inhibition ratio of weeds Narrow reached (84.48%).Results showed a variance among cultivars in it's characteristics .As the Abu - Graib cultivar was superior in weeds competition and gave less dry weight of weeds Narrow leaves which were (4.02 gm2), gave less dry weight of weeds Broad leaves which were (22.87 gm2 ). and gave best ratio of plant height (90.57cm ), number of tillers (622.78 mˉ2), number of spikes (572.80 mˉ2) , weight of 1000 seeds ( 32.67 gm ), seed yield ( 5.56 ton hˉ¹) , biological yield (15.33 ton hˉ¹), harvesting index(36.18 %) and protein yield (721.78 kgm hˉ¹). Either IPA - 99 cultivar was superior in gave best ratio of flage leaf area (32.46 cm 2), spike length ( 11.44 cm ), number of seeds per spike (60.73) and protein content ( 13.55% ).AbstractBThere were an interaction between treatments control and wheat cultivars in all characteristics except the spike length , number of seeds per spike , protein content and protein yield . Results of the study showed that the use of the spray (Topic +Lintur) herbicides with Abu - Graib cultivar give the highest ratio of seed yield (6.10 ton hˉ¹) and protein yield (829.66 kgm hˉ¹)
