This study was aimed to investigate combining ability among maize inbred lines. Randomized complete block design with three replicates was used to study the general combining ability of parents, and specific combining ability of 12 F1s. Combining ability was studied in a partial diallel cross in maize for traits yield and attribute at two locations (Qlyasan and Kanipanka) at Sulaimani Governorate. The cross 3×6 produced the highest value kernels yield and most of the attributed traits as the average of both locations. Mean squares due to crosses, GCA and SCA were highly significant for most traits as the average of both locations. The ratio of σ²gca/ σ²sca was found to be less than one for all traits exce

This research aimed to measure and analyze the impact of exchange rate shocks on some variables of the Iraqi economy during (1990-2022), because of the different effects of these shocks on the macroeconomic variables represented in money supply and agricultural output. Exchange rates are related to the policy chosen by the Central Bank of Iraq in managing the foreign exchange market and in the rentier nature of the Iraqi economy. The research uses a quantitative method in estimating the levels of the impact of exchange rate shocks on some economic variables. Several methods are conducted to achieve the goals, including the VAR model, variance decomposition and Impulse Response Functions. The results showed that e

Thirty Awassi lambs with an average body weight of 25.93 ± 0.42 kg and 3- 4 months old. Lambs were divided into three groups (10 lambs in each group) the first group was fed a diet contained 11% of sunflower cake (T1), the second group was fed a diet contained 11% of low degradable sunflower cake (T2), while the third group fed a diet that contained 11% of low degradable sunflower seeds (T3). The results indicated that reduce sunflower seeds degradability in (T3) led to a significant increase (p≤ 0.05) in the length of right and left testes (8.35 and

This study was conducted at the open fields of the Agricultural Research Station in Dohuk Governorate during the year 2019 on the tomato crop, a local variety. In this study, the effect of chemical pesticides (Imidamex, Matrixine plus) and biological pesticides (Antario KAB,  Biocure) were tested on the percentage of leaf infection, number of larvae, the percentage of fruit infestation and the rate of productivity of one plant. The results revealed that the lowest percentage of leaf infection and the lowest number of larvae appeared with plants treated with Biocure, with an average of 22.7% and 0.36 larva/leaf, respectively.

Ten soil sites were chosen in Iraqi Kurdistan region, included the governorates of (Sulaimani, Arbil, and Duhok). These soils were characterized by their similarity in texture, parent material, topography, climatic conditions, and equal rainfall, in order to study the use of the center of gravity equation and mineralogical properties in evaluating the state of potassium in soils of different plant coverage (Forest, crops, and uncultivated soils). Results showed there was a variation in the values of calculated center of gravity for studied soil samples, which ranged between (0.83 – 1.63). The variation in these values was attributed to the variation between the studied soils in their ability for potassium supplying, depending o
