Anbar Journal of Agricultural Sciences,

An experiment conducted in pots under field conditions in the fall seasons of 2017 and 2018 at the College of Agricultural Engineering Sciences, University of Baghdad, to improve the field emergence in sorghum, in which three factors were studied. 1st factor was the variety (three varieties: Inqath, Rabeh and Buhoth70). 2nd factor was priming treatment (unprimed seed and primed seed soaked for 12 hours in a solution containing 300 + 70 ml L-1 of gibberellic and salicylic acids, respectively). 3rd factor was saline stress (tap water as control (1.26), 6, 9 and 12 dS m-1). RCBD design was used with four replicates. The results showed that Buhoth70 cultivar exceeded the others; also the primed seed exceeded the unprimed seed in the traits of the first and final count of emergence, daily emergence rate, emergence energy, emergence rate index and emergence index in both seasons. The control treatment was superior in the above traits, while the values of these traits decreased as the saline increased, and no emergence accrued at the highest concentration (12 dS m-1) in both seasons. The cultivars varied in their ability to withstand salt stress at the same stress level, and that the seed priming treatment has improved their performance to withstand salt stress compared to the unprimed in both seasons. It can conclude that there is a role for genotype and seed priming in improving seedling performance to tolerate salt stress.

Anbar Journal of Agricultural Sciences,

The research aims to detect the seasonal phenomenon of the monthly prices of the cucumber crop in Baghdad City and for the period (January 2010 - December 2015), as well as the determined of the time series of the monthly prices of the cucumber crop follow the additive or multiplicative model. The research concluded that the monthly prices of cucumber crop contain a seasonal composition(seasonal variations), this confirms the nature of the pattern that the cucumber crop has been affected by the season to a large extent. The research concluded that there was a rise in the prices of the cucumber crop during certain months of the year. This is confirmed by the results of the research, which will be reflected in one way or another on lower prices in the months of high sales according to the law of supply and demand. Seasonal time series and autoregressive integrated moving average (SARIMA) models were used. The results showed that the appropriate and efficient model for representing the time series data for the monthly prices of the cucumber crop is the SARIMA double seasonal model (2.1.1) (0.1,1) 12. According to the estimation results of this model, the monthly prices of the cucumber crop were predicted at (60) observations and for the period (January 2016-December 2020). The results were consistent with those in the original time series. The research recommended the necessity of preventing import at peak time and the need to work on the development of laws and legislation to protect the local agricultural products from the importer as well as the imposition of taxes and customs duties on imported products and not to allow entry into Iraq in the peak season of production.

Anbar Journal of Agricultural Sciences,

An experiment was achieved in laboratories of college of Agriculture / Anbar University. A sample of clay loam soil with 50% lime content was brought from sefen mountain, Shaqlawa district / Erbil province, to study the effect of lime percentage on soil spectral reflectivity. Different lime percentage were removed from origin soil using 0.1 N HCl to obtain same soil texture with 40%, 29.5%, 24.5%, 20%, 15.8% and 9.4% lime contents. Spectroradiometer was used to measure the reflectance of the soil with different lime levels at 22% soil moisture content. The result showed an increasing of the soil reflectance with increasing of lime content. Also the result showed an absorption band at 2350 nanometer was appeard, which may be attributed to the presence of lime in soil. It was noted that the depth of the band was increasing with increasing lime percentage in the soil. Results also showed that a significiant correlation between lime content and reflectance in the all studied bands, especially with the two near infrared bands (B6 and B9) was found, whereas the correlation coefficient (r) for the two bands were 0.968 and 0.958, respectively. The quantitative relationship between the two variables was also found. The linear, quadratic and cubic models were efficient to forecasting lime content from reflectance data at near infrared band (B6). The determination coefficient (R2) for the three models were 0.93, 0.98 and 0.99, respectively. While the standard error values were 3.8, 4.8 and 2.7, respectively.

Anbar Journal of Agricultural Sciences,

The experiment was carried out at two locations, the first in Ramadi - Kaldia (80 km) west of Baghdad, the second at the farm of College of Agriculture, University of Baghdad, during the spring season 2017, in order to study the effect of concentrations and application growth stage of ethephon on growth, yield, and its components of sorghum (cv. Buhooth 70). Split plot arrangement was used according to RCBD. The application growth stage 4, 6 and 8 leaf growth stage, occupied the main plots while Ethephon concentrations 0, 500, 1000 and 1500 mg L-1, occupied the sub-plots. Results showed at both seasons, that the high concentration (1500 mg .L-1) gave the lowest plant height, leaf area, number of leaves and grain yield, thus reducing the biological yield 2.302 and 2.515 ton ha-1, for both locations respectively, While the concentrations 1000 and 500 mg.L-1, gave the highest grain yield 3.976 and 3.741 ton ha-1, for both locations respectively, the application times according to growth stages also had a significant effect on number of days to flowering stage and maturation also weight of 500 grains and grain yield. Application at 4 and 6 leaf growth stages gave highest grain yield in both locations 3.464, 3.673 ton ha-1 respectively, also the most traits under study were significantly influenced by the interaction between concentrations and application time, the highest yield 5.127 ton ha-1 in Ramadi location, was obtained from interaction treatment (1000 mg L-1 * 8 leaf growth stage) was while in Baghdad location the interaction treatment (500 mg L-1 * 6 leaf growth stage) gave the highest yield 4.623 ton ha-1

The objective of this study was to obtain the of best method carbonate removal from soil without effect in mineralogical properties. Three soil treatments for soil high content in calcite (Tall Keef region).Were used HCl acid (0.2N), sodium acetate pH (5) treatment and control treatment were conducted compared with control treatment.Results showed Bulk X-ray and XRDclay mineral were that use of HCl acid Caused to removal all carbonate without the effecting in quality and quantity of minerals Comparison with first treatment that it was not great influence. The group of mineral were diagnosed for the three treatments by using the Bulk x-ray showed dominate quartz,calcite,palygorskite,feldspar and kaolinite respectively,while the XRD for clay realated the rule of chlorite, illite,semctite and kaolinite respectively,as for FT-IR appearance group are bands important (1450 )cm-1,which represents carbonate group (dolomite-calcite)and Disappearance with third treatment without second,therefore acetate method is considered inappropriate for measurements which means to remove the carbonate. Meaning that use of HCl acid (0.2), N is optimum method.
