A field experiment was carried out in Kirkuk Governorate / Riyadh dis-trict in the wooden canopy of the Riyadh Mixed Vocational Preparatory School during the season 2021/2022, to find out the effect of the quality of irrigation water and the sources of organic matter on the growth and yield of faba bean in two gypsum soils. The experiment included three factors, the first factor (3): without addition, compost, sheep waste, and the second factor (soil). : 3.2 %, 6.14% and 13.50%. The third factor (water quality): (river wa-ter 1.13, well water 2.56 and earthquake water 6.14 (Desismans M-1). The re-search was carried out according to a complete randomized design (CRD) with three replications. The results showed that the level of salinity in the ir-rigation water, the source of organic fertilizer, the soil content of gypsum and the interaction between them had a significant effect on the characteristics of growth, yield and soil characteristics, and that the highest mean of plant height, dry weight of shoots, grain yield, pod yield and number of root nodes after harvest were achieved when irrigation with water overlapped. fresh with the addition of sheep waste in a soil with a gypsum content of 6.14%, with an average of (75.33) cm, (23.32, 27.84, and 198.03) gm pot-1 and (20.33) knots pot-1, respectively, while the overlap treatment was achieved (irrigation with fresh water with The addition of sheep manure in a soil with a gypsum con-tent of 3.2% had the highest average concentration of available nitrogen and available phosphorus, which reached (53.00 and 13.69) mg kg-1, respectively.

A field experiment was conducted on garlic in the fall season as a factorial experiment with a randomized complete block design to study the effect of concentrations of humic acid ( H0-H2.5-H3.5) ml / liter-1 and the second planting dates (1 October - 20 October - 10 November). The results exceeded the concentration of 2.5 ml / liter-1 in most charac-teristics of vegetative growth compared with other concentrations of humic acid, as it gave significant differences in the second date of plant height, number of tubular leaves and number of lobes (11, 00) plant leaves-1 , from the second date of the first concentra-tion (2 and 3) ml / liter-1 , as well as the superiority of the first date in dry weight and fresh weight compared to other dates, as the interventions reached between the first date and the first concentration, no significant differences appeared in the characteristic of the experimental unit outcome .

This study investigates the chemical composition of volatile oils ex-tracted from stem, leaf and flower parts Lavandula angustifolia Mill. This study was carried out at the trial plots of Recep Tayyip Erdogan University Faculty of Agriculture in 2020. The active ingredient content of the lavender plant was determined by harvesting the stem, leaf and flowers during the full blooming period. The oil was extracted using the hydrodistillation method, with a NeoClevenger device. The essential oil fire in the oil harvested during the full decomposition period were determined by using SPME (Solid Phase Microextraction) method using Gas Chromatography (GC-MS) device. As a result of the analysis, nearly 50 different volatile oil components were detect-ed in all investigated plant parts. The obtained max.-min. values were as fol-lowing: Camphor (33.1-13.77 %), Eucalyptol (27.91-13.53 %), Linalool (12.69-1.61 %), γ-Cadinene (5.83-0.88 %), β-Pinene (6.16-0.32 %), α-Terpineol (5.79-1.96 %), α-Bergamotene (5.7-0.89 %), and Caryophyllene oxide (5.25-0.26 %). Different components of medicinal importance could be detected in different parts of this species. These compounds could be isolated and used for further basic investigations.

The study included ten genotypes of upland cotton, in 2022 at Rahmaniyah (Mosul) using a randomized complete block design with three replications, it was analyzed statistically to identify the nature of the differences between the genotypes. The stages of the cluster analysis showed that the genotypes were distributed in eight groups, the first, second, fourth, fifth, sixth and seventh included one genotype for each of them, respectively COKER310, MONTANA, SPERO, LACHATA, CANDIA and EDESSA, indicating the variation between it and the other genotypes, which is due to the variation in their genetic origin, which was thus reflected on their performance, while the other groups included two genotypes each. It is concluded from the results of the cluster analysis that there is a strong convergence between the pairs of genotypes W888 with IK259, and FLASH with BA440, because they have the least Euclidean distances, and this necessitates avoiding crossing between them, while the highest distance between the genotypes COKER310 and FLASH, was an indication of high genetic variation between them and other genotypes, that may be due to the difference in their genetic origin or to their possession of preferred main genes that the other genotypes lack, which encourages their inclusion in crosses with genotypes that showed distinguished genetic heterogeneity, to take advantage of the phenomenon of heterosis and the segregations that result from it.
