The study was done during winter season 2020-2021 at field of College of Agricultural Engineering Sciences, Duhok University, to evaluate the influence of different phosphorus fertilizer P2O5 rate (0, 60, 90, 120kg ha-1 on yield and yield components of four promising bread wheat Bura, Jehan-99, Apst-35 and Apst-26. The experiment was Laid out in factorial experiments using randomize complete block design with three replications. Significant difference in plant height, flag leaf area (cm), spike length(cm), No. seed spike, weight of seed per spike, 1000-seed weight and total yield were observed by the application of different phosphorus fertilizer 120kg ha-1. However, only days to 75% flowering was not significant affected by different rate of phosphorus fertilizer. Also the results exhibited that the Apast-35 was significant in plant height (104.91cm), flag leaf area (40 cm2), spike length (15.4cm), No. seed per spike (37), seed weight of spike (1.48g), 1000-seed weight (41.09g) and total yield 3.66 (t.ha-1). The simple correlation exhibited positive and significant between yield and plant height (0.89), leaf area (0.85), 1000-seed weight (0.76), No. seed per spike (0.87) and weight of seed spike (0.92), this main these traits were intributed to increase the yield under rate 120kg ha-1of phosphorus P2O5.

Manganese (Mn) and iron (Fe) are the two vital micronutrients for plants and moreover essential nutritional health components in humans. Iron deficiency is common in humans and causes many health issues. In this survey, wheat grains of two major wheat cultivars were analyzed for their Mn and Fe concentrations beside the natural gradient of micronutrient availability across Sulaymaniyah province, Iraqi Kurdistan. However only 20% and 7.5% of the soils samples were Mn and Fe deficient or below recommended level. The considered micronutrient concentrations in the grains of wheat were in the acceptable range which are reported globally (range 41.3 and 37.6 mg kg-1 respectively). Furthermore, high application of nitrogen and phosphorus fertilizer in the studied calcareous soils could be strongly affected on the studied micronutrients concentration in the studied grain samples. The results indicate that adequate levels of Mn and Fe in the surveyed grains is a beneficial guide for quality of grains associated with human heal

Boron is considered one of the necessary elements for the growth of plants, it participates in the process of pollination, fertilization and plant fruit setting. It enhances the formation of adenosine triphosphate (ATP) and serves as a compound that accelerates the movement of sugars into the active areas during growth throughout the reproduction stages of the plant. Shortage in boron causes slowness in plant growth, decrease in production and degradation of crops quality. It is found that adding boron to some industrial crops such as (sesame, sunflower, safflower, rapeseed, soybean, cotton, flax, and sugar beet) leads to stimulating plants, accelerating the growth, and increasing the production of these crops, through its influence on many physiological functions that determine the growth and development of crop yield. It was noted that boron facilitates and speeds the transfer of sugars to the plants, as it interacts with sugars, forming a sugar complex with boron, this works on the movement of boron through cell membranes with ease compared to the movement of sugar molecules alone, and this may be due to the formation of regions or points of reception of sugar in modern growth or because boron may be considered one of the components of plant membranes, It also works to regulate enzymatic activity.

A field experiment was carried out in a Moderate rainfall area (Jleokhan) in the Nineveh Governorate during the agricultural season 2018-2019 to study the effect of press wheels (use (+) and non-use (-), row spacing’s (17 cm and 34 cm), and sowing rates (80, 100 and 120 kg. ha-1) in the yield and its components of the wheat crop (Triticum aestivum L) Adana-99 cultivated with Zero Tillage (ZT) planting methods  and Conventional Tillage (CT) as a control treatment.The results showed that the planting methods (ZT 17+P) and (ZT 34+P) achieved the highest significant values ​​in the traits of plant height, the weight of 1000 grains, and grain yield. (ZT 17+P) planting method was achieved the highest significant values ​​ in the traits of tillers No. m-2, spikes No. m-2, biological yield and straw yield. The (ZT 34+P) planting method recorded the highest significant value in protein ratio trait. The sowing rate (120 kg. ha-1) achieved the highest significant values in the traits of tillers No. m-2, spikes No. m-2, and grain yield. In grain yield trait, the interaction between the planting  method (ZT 17+P) with all sowing  rates and the planting method (ZT 34+P) with (120 and 100 kg. ha-1) sowing rates  achieved the highest significant value in grain yield, while the interaction between CT  with (80 kg. ha-1) sowing rate has the lowest significant value in grain yield.

The experiment was carried out at the farm at Filed crops Department , College of Agricultural engineering sciences , Duhok University in season 2018-2019 to construed selection index for five faba bean genotypes under different levels of phosphorus fertilizer .The results exhibited that all selection indices include the grain yield gave relatively efficiency , the best selection index were grain yield, number of pods plant-1 and number of seeds pods-1 , so that we can using these characters as criteria’s of selection of faba bean genotypes . Also the results showed that the highest mean selection index was 216.26 for latti kia genotype and significant and difference over all other genotypes .
The heritability broad sense was high for all studied characters and ranged between 0.94 to 0.99 . Regarding to the genetic advance as mean gave high values for first pod height (57.10) , grain yield plant-1 (43.97) , number of main branches plant-1 (33.92) and number of pods plant-1 (31.52) and medium for plant height , days to 75 flowering , number of nodules plant-1 and number of seeds pod-1 . So that we can using these desirable characters to improve the faba bean genotypes .
