A field experiment was carried out in the second agricultural station of the College of Agriculture - University of Al-Muthanna in the Al Bandar area (2 km from the city center), during the season (2020-2021) to know the effect of different levels of potassium fertilizer coated and are K0 (without addition), K1 (30 kg.K.H−1), K2 (60 kg.K.H−1), K3 (90 kg.K.H−1) and K4 (120 kg.K.H−1 without coated) On the vesponse of the genotypes of the wheat (Iksad 59, Iranian, Iksad 901, Iksad 133 and Boohooth 22), According to what the process requires of printing to arrange the splinter panels using a design R.C.B.D and three repetitions, As the potash fertilizer treatments were placed in the main panels (Main-plots) While the genotypes were placed in the secondary plates (Sub-plot). The results showed a significant difference between the genotypes in the traits studied as the Iksad 133 genotype superior in the biological yield, while the Iranian genotype was superior in the weight of 1,000 seeds and the harvest index, and as response to potassium fertilizer, The coated treatment has outperformed 30 kg.K.H− 1 The No. grains spike−1 and the weight 1000 seeds. It also excelled in the seed yield, vital yield and harvest index, which averaged reached 8.03 tons H−1 and 18.33 tons H−1 and 43.98 % respectively, while the coated treatment supertor 90 kg.K.H− 1 significantly in the No. of fertile spikes. M2. As for the interaction between the two factors, the combination (Iksad 133 x K3) was superior in the No. of fertile spikes, and the combination (Iksad 59 x K4) in the No. of spike grains, while the two combinations superior (Boohooth 22 x K1) and (Iksad 133 x K1) in grain yield, which averaged 9.11 and 9.06 tons ha−1 respectively, and the combination (Iksad 133 x K1) was superior in bio-it give high mea reached 21.27 tons.ha−1, The combination (Iranian × K2) was superior in the harvest index, It reached 48.75%.

A field experiment was carried out at the Agricultural Research and Experiments Station of the College of Agriculture, Al-Muthanna University during the summer season 2020. Pots of 15 cm diameter were used for planting the genotypes, with (SS, F-RCBD) and three replications. Ten different genotypes rice were used (FRI, FR2, FR15, FR16, FR17, FR18, FR21, FR25, FR27), as well as the rice varieties, which are Pokkali, Anber-33 and Jasmine, were irrigated by three levels of salty water (4.5, 7.5 and 15 ds/m). The results of the experiment showed that the tolerance of the genotypes FR21 and FR12 to salinity was associated with containing low concentrations of sodium (0.38 and 0.42%) respectively in the shoot, and a high concentration of potassium in the shoot (1.22 and 1.23%) respectively, and this result was reflected in the ratio of potassium to sodium in the shoot total was (3.30 and 2.95%) compared to the salt-tolerant variety Pokkali. Salinity caused a significant decrease in all the studied traits of the genotypes, especially at levels 7.5 and 15 ds/m, in growth traits (plant height, flag leaf area and panicle length), yield and its components (number of productive tillers, weight of 1000 grains and yield per plant). The most potent varieties in salt tolerance were FR12 and FR21, as they gave the highest yield of grains (11.72 and 16.67 g/plant, respectively), flag leave area (30.47 and 27.76 cm2 respectively). Detection for OsHKT4 and OsHKT6 by PCR proved the presence of primary locus that utilized by each gene with successfully fused genes as well as their stability under Iraqi cultivation circumstances, particularly in the case of FR12 and FR21 where OsHKT4 lanes were very obvious (2840 Kb) and the bands of OsHKT6 at (2324 Kb), which resemble to that in Pokkali Japanese salt tolerance rice. These results suggested the variation among investigated rice varieties in their tolerance to salts, where FR12 and FR21 were best in their performance under applied the salt levels conditions.

"The experiment was carried out during growing season (2018-2019) at the Rice Research Station in Mishkhab / AL-Najaf-Iraq, The seeds of 27 genotypes were sowing with the aim of selecting the best economically yielding genotypes for cultivation under the conditions of ALNajaf. The experiment was arranged with a randomized complete block design with four replication. The results showed significant differences between the genotypes for all the traits under study. The G27 genotype showed superiority for traits exceeded, number of grains per panicle, grain yield ton. ha-1 , the biological yield ton. ha-1 and the sterility percentage (%), with averages were 220.17, 13.34, 27.95, and 4.48, respectively. Whereas, the genotype G14 was superior with the characteristics of the number of fertile panicles and the duration of fullness the grain, which averaged 37.00 and 82.25 respectively, while the genotype G13 was significant for weight of 1000 grains (g), and the genotype G21 was superior with the flag leaf area which gave an average 32.45 cm2 . Through this study, genotypes (G1, G2, G12, G15, G16, G17, G18, G21, G25 and G27) showed the best field performance in terms of growth characteristics and the outcome of their selection for the second agricultural season."

The experiment was conducted in the field at the Warka extension to the Agricultural Extension Service Department in the Ministry of Agriculture for the winter season 2022-2021 (north of Muthanna ), With a view to understanding how efficiently five newly introduced genotypes of coarse wheat and determining the best ones for the region’s conditions under the influence of different planting dates, The experiment was applied using Complete Block Design (R.C.B.D.) and Split Plot Design, along with three replications. the four dates for sowing (1/11, 10/11, 20/11 and 30/11) occupied the main plates, while the genotypes (G1133, G65 and G1105 and G1229 and the approved variety for comparison, Bohooth-7, Divided Plots. The findings indicated that the first meeting D1 (1/11) outperformed the number of spikes and the weight of one thousand grains with averages of (334.7 spikes/m2 and 49.99g), while the second date D2 (10/11) was superior in terms of spike count and grain weight, with averages of (50.00 grains, spike-1. and 13.92 tons.ha-1), while the third date D3 (20/11) exceeded the harvest index by (34.57%), While genotype G65 achieved the highest biological yield of 13.00 tons.ha-1, and genotype G1229 achieved the highest average number of spikes, which amounted to 3493 spikes.m-2, and genotype G1133 gave having the most grains per spike, which amounted to 50.97 grains. Spike-1, while the genotype gave Genetic G1105 The highest weight of a thousand grains was 43.93 g.

A field experiment was carried out at the Warka extension farm affiliated to the Agricultural Extension Department in the Ministry of Agriculture (north of Muthanna) during the winter season 2022-2021 (15 km from the center) in order to know the effect of different planting dates on the qualitative characteristics and grain yield of several combinations of coarse wheat. The experiment was applied using the Split Plot Design method and using the complete sectors design (R.C.B.D) and with three replications. The four sowing dates (1/11, 10/11, 20/11 and 30/11) occupied the main plates, while the genotypes (G1133, G65 and G1105 and G1229 and the approved variety for comparison. bohoth-7) Secondary panels. Split Plots. The results showed that the first date D1 (1/11) outperformed the grain protein, specific weight and dry gluten, which averaged 14.100%, 79.83 kg/ha and 9.55%, respectively. While the second date D2 (10/11) outperformed the grain yield 4.54 tons/ha. In succession and the fourth date, D4 (30/11) was superior in wet gluten content, which amounted to 28.59%, while the local cultivar Buhouth-7 was superior in grain protein with an average of 13.633%, while the genotype G1229 was superior in specific weight and content of wet gluten and dry gluten, which averaged 80.83 kg/hectoliter, 28.80% and 9.600%.
