The experiment consist of two factors; first one was three concentrations of Algae Extract (AE): (without, seed soaking and spraying), seed soaked with conc. 4ml (AE).L-1 and sprayed plants with conc. 1.5 ml (AE).L-1. The second factor was Humic Acid (HA) with three levels: (0، 2 and 4 kg (HA). Ha-1). The experiments carried out in a Split Plot Design with three replications, the main plots assigned to (AE), while (HA) considered as sub plot. The results were as following:
Soaking the seeds and spraying the plants with algae extract increased significantly the yield and its components as well as the number of pods.plant-1, the number of seeds.pod-1, weight of seed per pod, weight of 100 seeds, and the total yield of seeds were superior with no-added treatment in Rashidiya and Bashiqa sites respectively. While the protein percentage in seeds at Bashiqa was superior for 2 and 4 levels of Humic Acid.Ha-1 in all studied traits compared with without addition treatment, for both sites. The interaction of seed soaking or spraying plants with seaweed extract with levels of Humic acid (2 or 4 kg. ha-1) showed significant superiority for all traits studied in both locations.

This study was conducted at the field of the College of Agricultural Engineering Sciences/ University of Duhok/ Duhok Governorate, for the season 2018-2019, the aim of this study was to determine the effect of different grain sizes and different methods of seed rate using different equations with two varieties of bread wheat (Triticum aestivum L.) on the performance of vegetative growth of bread wheat, by using R.C.B.D design with three replicates each replicate had (16) plots, the study consisted of three factors : the first factor were two varieties of wheat (Tammuz 2 and Adana 99). The second factor consisted of two grain sizes, medium and large and the third factor was consisted four different equations to estimate seeding rate . Results revealed that wheat varieties (Tammuz 2 and Adana 99) differed significantly in some vegetative growth traits as in plant height, number of emerged seedlings , number of tillers without spikes, flag leaf area, Total chlorophyll content, Grain size had no significant effect on vegetative growth traits except for number of tillers with spikes. Seeding rate estimation methods were significantly affected on traits emerged seedlings and number of tillers without spikes only. Interaction between grain size and variety showed a significant effect on plant height, number of emerged seedlings, number of tillers with spikes, flag leaf area and total chlorophyll content. Interaction between variety and methods of estimation seeding rate had a significant impact on most of the vegetative traits as in plant height, number of emerged seedlings, number of tillers without spikes, flag leaf area and total chlorophyll, but had no effect on the other traits. Interaction between size and methods of estimation emerged seeding rate had a significant impact on some vegetative growth traits as number of emerged seedlings, number of tillers with spikes and number of tillers without spikes. Triple interaction of variety with grain size with methods of estimation seeding rate had a significant impact for all the vegetative growth traits excluding leaf area index.

The study carried out during the period 1/11/2019 until 1/3/2020 in the laboratories of the College of Agriculture - University of Tikrit with the aim of determining the best varieties and storage periods in some qualitative and quality characteristics of bread wheat Triticum aestivum L. The experiment was designed with a Completely Randomized Design (C.R.D) in the under system of split- plot, where the study included two factors: the main factor varieties (Jihan 99, Sham 6, Wafea, Adana 99 and Puro) and the secondary factor, storage periods (60, 90 and 120) days. The results showed that the variety Adana 99 was superior in interfering with a storage period of (60) days in most of the traits, as it was recorded (77.39%) for flour extraction, (63.51%) for starch, (12.84%) for protein and (33.25%) for gluten. As for the sedimentation value, it was recorded (49.84 ml). The variety also outperformed the same by interfering with a storage period of (90) days in the percentage of oil (4.06%). As for the ash trait, it was significantly superior to the variety Sham 6, with an overlap with a storage period of (120) days (2.06 %) . We conclude from this study that the best varieties with a storage period are the interaction treatment between variety Adana 99 and a storage period of (60) days for the aforementioned characteristics and with a storage period of (90) days for Oil percentage trait .
