Abstract | ||
A field experiment was carried out during the autumn season of 2014 in the district of Daqouq in Kirkuk governorate to study the impact of five different genetic structures and mechanical and chemical control using several specialized pesticides for maize. The experiment included two factors, the first five structures of maize (Kadz, Munarj, Apcaro, 106 and DKC6586). The second is the three levels of two herbicides (Accent, nicosulfuron with concentrations of 30, 45 and 60 g / 400 lt.) Covering one hectare area of Tissus Basis (rimsulfuron) with concentrations of 30, 45 and 60 g / 400 liters covering one hectare (three methods of control) (One-time digestion after 15 days of germination), the first two times with the first treatment, and the second after 15 days after the first treatment. The first time with the first treatment, the second treatment with the second treatment, the third treatment after 15 days Of the second transaction in addition to the coefficient in comparison, the RCBD was used with three replicates. Some of the traits of the crop (500 grain weight, total yield, total grain yield, and biological yield) were examined. The genotypes were found in their production capacity. (7.5) tons / h. The monarch gene was also superior to 500 grains and a total of 272.1 g and 779.2 g / plant respectively. Anti-annual bushes especially in the case of repeated hoeing for more than two times to complete extermination of these plants Which resulted in a significant increase in the qualities of the seed yield of maize, the treatment of the pesticide characterized by a concentration of 60 grams per hectare marked superiority in the control of annual and perennial bushes, which led to a reduction in the number and reduce dry weights with the increase in grain yield, On the rest of the experimental units in the case of hoeing for two or three times, the pesticide distinguished the pesticide Titus at a concentration of 60 grams per hectare by giving it the highest grain. Therefore, we recommend the cultivation of genotypes Cadiz and Monaraj, and the disruption of more than once, and chemical control with Herbicide characteristic Amaze 60 g per hectare. | ||
