During the 2021–2022 winter growing season, an experiment was carried out in two distinct locations: Field Crops Department Research Station-College of Agriculture and Forestry and Wana sub-district. The study aimed to investigate the influence of 3 levels from nitrogen fertilizer (0 , 75 , 150 kg N/ ha) and 3 zinc rates (0 , 20 , 40 mg/L) on the growth, and flax production (Linata variety). It was factorial experimentation with two factors set in a split-plot design within (RCBD) with three blocks. Main plots included 3 levels from nitrogen fertilizer, while sub-plots included 3 zinc rates. The results showed that the 75 kg N/ha fertilization level significantly outperformed in seeds number/ capsule , capsules number/plant, 1000-seed weight , seed yield, oil percentage in seeds and oil yield in locations the College and Wana, respectively. Meanwhile, 150 kg N/ ha fertilization level excelled in plant height and branch number/ plant for locations. The data also showed that the 20 mg/L zinc concentration significantly outperformed in plant height, branch number/plant, and oil percentage in seeds. Conversely, the 40 mg/L zinc concentration excelled in seeds number/ capsule , capsules number/plant, 1000-seed weight , seed yield and oil yield in both locations. Moreover, there was a significant interaction between the 75 kg N/ha fertilization level and the 40 mg/L zinc concentration in capsules number/plant at the Wana location, and seed yield for locations, respectively.

From the field of Khabat Technical Institute- Erbil Polytechnic University the research was conducted in the summer season of 2021. It shows peanut yield and oil response to application methods and zinc concentration. A factorial experimental design was applied in a randomized complete block design (RBCD) with replications; the first factor represents seed treatment by four concentrations of Zinc (0, 1, 2 and 3 g Zn kg seed-1) and second factor was a foliar spray application by four concentrations of Zinc (0, 2000, 4000 and 6000 Zn mg liter-1). The combined effect of seed treatment by 1 g Zn kg seed-1 and 2000 mg liter-1 of zinc foliar spray application, produced the highest value of a number of pod plant-1, pod and seed yield (kg ha-1), oil and protein yield (kg ha-1), but the seed treatment by 2 g Zn kg seed-1 and 4000 mg liter-1 of zinc foliar application surpassed in weight of 100 pod (g), weight of 100 seed, oil and protein percentage while 1 g Zn kg seed-1 and 4000 mg liter-1 of zinc obtained the heights branches of plant-1. The interaction between seed treatment 1 g Zn kg seed-1 with 2000 mg liter-1 of zinc foliar application recorded the highest number of pod plant-1, seed yield (kg ha-1), oil percentage, oil and protein yield (kg ha-1). The interaction treatment 2 g Zn kg seed-1 with 4000 mg liter-1 of zinc recorded the highest value in weight of 100 pods (g), weight of 100 seed, pods yield (kg ha-1) and protein percentage

This experiment was conducted during the winter season of 2016-2017 at the Qlyasan Agricultural Research Station, College of Agricultural Engineering Sciences, University of Sulaimani, using split plot design the main plots conducted in (RCBD) with three replicates to study the effect of three levels of NPK fertilizer on the growth, yield and yield component of rapeseed varieties. The three varieties; Serw, Hybrid and Reandy were implemented in the sub plots, three NPK fertilizer levels (0, 150 and 300) kg NPK ha-1 from NPK fertilizer complex (15-15-15), were implemented in the main plot. Results of this investigation confirm that variety Reandy produced the best values for most characters, and application of 300Kg NPK ha-1 was found to be the best level for this crop. The character seed yield showed positive and highly significant correlation with most characters including plant height, number of leaves per plant, number of pods per plant, the weight of pod per plant, 1000-seed weight, dry matter weight per plant, LA, and biological yield. Maximum positive direct effect on seed yield recorded by weight of pod per plant which was 0.495, while Maximum positive indirect effect on seed yield was 0.483 recorded by weight of pod per plant via number of pods per plant.

A comparative agronomical experiment was conducted at research station/ Department of Horticulture and Landscape/ College of Agriculture/ Tikrit University, to study the effect of two different soil textures (loam and silt loam) on growth and yield of six varieties of okra. The two soil textures were analyzed for pH, nitrogen, organic matter, phosphorous, Ca, K, Mg etc. at the Central Laboratory of Soil Science and Water Resource Department, College of Agriculture, Tikrit University. Six okra varieties of okra were used in this experiment (i. e., Clamson, Hussainawia, Sultani, Btra, Clemson and Clemson spinless). The experiment was carried out with a Randomized Complete Block Design with Split plot arrangement with four replicates. Data were recorded for plant height, stem diameter, branches number on main stem, total number of branches, pod length, pod diameter, pod weight, pods number, yield per plant and percentage of dry matter in pod. Results indicated that plant height, branches number on main stem, pod weight, pod number and yield per plant produced in Loam soil were significantly higher (P ≤ 0.05) than those produced in Silt loam soil. Irrespective of soil texture, the stem diameter, branches number on main stem and total branches produced in Btra variety, whereas, pod diameter, pod weight, pod number and pod yield per plant produced in Hussainawia variety were significantly higher (P ≤ 0.05) than those produced in other varieties. But, pod length did not differ significantly (P ≤ 0.05) between six varieties. It can be concluded from the present findings that Btra and Hussainawia cultivars may be produced in different soil..

This experiment was conducted at farm of field crops department, collage of agriculture, Duhok University in spring 2018 to construct selection index. The results showed that all selection indices include the yield gave relative efficiency equal to those when used the yield only, the increase in efficiency was very low and not important, selection index was a few relative efficiency as a compered with efficiency index which include the yield, therefore, the best selection index was depend on the yield only to select the better indices and some variance components to twenty maize genotypes according to Randomize Complete Block Design with three replication, also the result exhibited that the GCVwas medium for all characters except grain yield while, the PCV was high for grain yield, ear height and 300 grain weight and medium for the rest characters. The GAM gave high values for grain yield, plant and ear height and leaf area, the value range between 22-40 while the others characters showed medium values. On other hand the results showed high heritability broad sense ranged from %80 to %99 for all characters except 300- grain weight.
