This study was aimed to investigate the appropriate planting date and tolerance to adverse growing conditions in the spring season through seeds stimulation technology. A field experiment was carried out in the spring seasons of 2022 and 2023 according to a randomized complete block design in a split-plot arrangement with four replications. The main factor is planting dates (February 15^th, March 1^st and 15^th, and April 1^st and 15^th). The secondary factor is seeds stimulation (potassium nitrate 6 mg L^-1 + licorice extract 6 g L^-1, as well as soaking with distilled water only). The stimulated seeds (potassium nitrate + licorice extract) and the planting da

An experiment was conducted at the central lab of Graduate studies - College of Agriculture, University of Baghdad during 2015-2016.

A laboratory experiment was carried out at the Department of Soil Sciences and Water Resources, College of Agriculture, University of Baghdad. Silty clay soil was treated with three salt solutions (NaCl, CaCl₂ and mixed NaCl–CaCl₂). Homogeneously packed soil columns (10 cm, 40 cm) were leached six times using tap water. Effluent samples were collected to determine ion concentration Cl^-, Ca⁺⁺, Na⁺, K⁺ and Mg⁺⁺. Breakthrough curves were used to estimate solute transport parameters (retardation factor, peclet number) using an analytical solution of convection-dispersion equation (CDE) by CXTFIT program. The results showed that relative concentration of ch

Field experiment was carried out during spring seasons of 2015 in AL-Rasheed township southern of Baghdad, Iraq to study the effects of irrigation methods on water content distribution, water use efficiency and yield of corn.

The aim of this work was to check the presence of the dumping from neighboring countries of Iraq, Turkey and Jordan. The margin of dumping was calculated by taking the difference between the normal value and the export price. If it exceeds 2%, then there is dumping. Product dumping in Iraq has increased since 2003, and it is increasing from year to year for many types of agricultural and food commodities. Main reasons are the high rate of imports and the absence of trade policies represented by customs tariffs which in turn control the trade exchange. The research concluded that there is an intentional dumping in the trade of some agricultural commodities with Iraq from neighboring countries. Trade exchange with these countries h
