Abstract A field experiment was carried out in Samawa desert (70 km west of Samawa city, Al-Muthanna governorate), during the 2018-2019 and 2019-2020 agricultural seasons, to study the response of three Iraqi cultivars of wheat (Tamooz2, Ibaa99, Abu Ghraib3) to three planting dates (November 15, 1st December and December 15) under Samawa desert conditions. The results showed the superiority of Tamooz2 cultivar in all traits of the yield components, it gave the highest averages of grain yield, which amounted 5.75 and 5.89 tons/ha−1, weight of 1000 grains, which amounted 29.79 and 31.06 gm, and the number of grains per spike, which amounted 73.02 and 73.76 for the 2019 and 2019-2020 seasons, respectively. The date of December 15th also surpassed in the traits of grain yield, weight of 1000 grains, number of spike grains, and the highest grain yield reached 5.62 and 5.58 tons/ha−1 for the two seasons 2018-2019 and 2019-2020, respectively, and the combination (Tamooz 2 x December 15) gave superiority over the other combinations in terms of grain yield which amounted 6.05 tons ha−1 (2018-2019 season) and Ibaa99 × December 1 gave the highest grian yield about 6.10 tons ha-1 (2019-2020 season).

A field experiment is conducted at Thi-Qar Province in AL-Shatra District located about 30 Km North AL-Nassiria City to study the response of three wheat Cultivars Triticum  aestivum L. to Growth regulators during 2014-2015 growing Season. The Cultivars are Latifia , AL-Rasheed and Iba 99. The growth regulators are Alga600, Atonik and Azomin32%. Factorial experiment in R.C.B.D.  with three replicates is used . The results showed that Iba 99  Cultivar gives the highest plant height , Spikes/m2 and grain yield , with a means 80.83 cm , 272.25 spike/m2 and 3.06 Ton/h) Respectively . Azomin32%  growth regulator gives the highest grain /spike , 1000 grain weight and grain yield , with a means 66.00 seed/spike ,43.55 gm , 272.33 spike/m2  respectively. In addition the interaction between Iba 99 Cultivar  and Azomin32% growth regulator gives the highest Leaf Area , number of grain/spike and grain yield with means 45.10 cm2 , 70.00 grain/spike and 3.16 ton/ha respectively.The combination treatment Iba 99 with Atonik growth regulator gives the highest number of spike/m2  with a mean 279.66 spike/m2  . In the other hand, the same cultivar with Atonik and Azomin32% gives the highest mean of grain yield with a amount 3.16 ton/ha.

Dwarfing Genes

Norin 10 based dwarfing genes (Rht1 and Rht2) have been widely exploited for increasing the grain yield in bread wheat (Triticum aestivum L.) by improving partitioning of assimilates to grain. Eight semi-dwarf wheat genotypes having either Rht1 or Rht2 dwarfing genes were compared with a tall control named, Kheri (rht) having no dwarfing genes were evaluated at Rajshahi University, Bangladesh for yield and yield contributing traits. Significant differences in grain yield and yield components were observed in genotypes under study showing the effects of dwarfing genes. Genotype Seri 82 (Rht1) and Kanchan (Rht2) had medium plant height of 75.73 and 72.22 cm respectively, highest number of tillers/plant (7.33 and 7.67), highest number of spikes/plant (6.33 and 6.67) resulted the highest grain yield per plant. Because the dwarfing genes not only provide lodging tolerance but also perhaps pleiotropically affected high yield by allowing more tillers to survive. Number of tillers/plant and number of spikes/plant showed very strong positive correlation with grain yield per plant in all the genotypes. Kheri (rht) with highest plant height (95.17cm) reduced number of tillers/plant (4.00) and spikes/plant (3.67) had the lowest grain yield per plant (3.85g). Aghrani possessed significantly the highest number of grains/spike with medium grain yield/plant (5.94g). The degree of relationship varied from genotype to genotype.DOI: http://dx.doi.org/10.3329/pa.v18i2.18075 Progress. Agric. 18(2): 49 - 55, 2007

Herbicide Treatment

In field experiments at Charlottetown, P.E.I., five herbicides evaluated at two rates of application on eight spring wheat (Triticum aestivum L.) cultivars showed no effect on dry plant weight 20 days after treatment. Herbicide treatment with dicamba resulted in a greater number of deformed heads per plot compared with the untreated in 1980 and with all herbicides except diclofop-methyl in 1981. More deformed heads occurred with dicamba and the 2,4-D/mecoprop/dicamba mixture at the higher rate of application in 1981 than with the other herbicides and the lower rate of application. All cultivars had more deformed heads than the untreated control when treated with 2,4-D, dicamba and the 2,4-D/mecoprop/dicamba mixture in 1981. Neepawa and Dundas had more deformed heads than the other cultivars when treated with MCPA. Head deformation by herbicide treatment had no adverse effect on grain yield in this study.Key words: Spring wheat cultivars, herbicides, head deformation, 2,4-D, MCPA, dicamba, diclofop-methyl
