This experiment was carried out during season of 2020 and 2021 at Erbil governorate to study the forage and grain yield performance of three maize hybrids Zea mays L. as influenced by irrigation skipping at different times. The experiment was laid out in split-plot design with three replications. The irrigation treatments were located at the main plots, and the hybrids were distributed at the subplots. Highly significant effects of irrigation treatments were recorded for forage, grain yield and most of its components at both seasons and their average. The differences among hybrids were not significant for forage yield at both seasons. It was significant for grain yield as the average of both seasons only. The fr

This study was conducted to evaluate the effect of feeding three levels of concentrate 2%, 3%, and 4% with or without additives of N-carbamylglutamate (NCG) on the digestibility, feed efficiency, and daily gain of Shami goats. Twenty-four male goats were used aged 8-10 months with an initial weight 32.687 ± 1.52kg divided into six treatments in a 2×3 factorial experiment/ Completely Randomized Design. Individual feeding was used for 70 days preceded by 14 days as an adaptation period. The results of increasing concentrate showed a non-significant increase in nutrients intake with superiority of NCG treatments and a significant increase (P<0.

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

This study was conducted on salmon(Atlantic salmon)Salmo salar products imported to Iraq, which are a whole fish removed head and tail, fillets, rings, fingers and cubes  evaluating of the sensory characteristics of these products and determining their suitability for human consumption.

This Study was conducted out at the Ministry of Agriculture's Poultry Research Station/Animal Resources Department/Agricultural Research Center. To see how body weight (BW) and leptin hormone (LEP) levels in breeder blood affect fertility and hatchability. 140 Iraqi local laying chickens (120 females + 20 males) aged 28 weeks were used in the study. Following the numbering of females, the birds were grown in individual cages and dispersed sequentially on cages. The experiment was divided into three periods, each lasting 28 days, during which the breeder's live body weight was recorded and divided into two categories (greater than 1.5 kg and less than 1.5 kg), and blood samples were collected at the end of each period to determine

This research was aimed to study the most important factors affecting the food security coefficient in Iraq for the period 2003-2020. Where the food security coefficient was calculated for the rice crop, the results showed that the rice food security coefficient amounted to about 0.55, which is nearly enough for six months, which requires maintaining the level of food security of rice and then study the factors affecting food security, considering the food security factor as a dependent variable, and each of the population, local production, available for consumption and imported quantities of rice as independent variables. Statistical and standard methods were used to find out the most important aspects of this subject in the ag

This study was aimed to reduce the clogging ratio using two waters qualities Sumael (LSI) and Bazalan (LSII). The physical treatment was carried out using complete filtration unit composed of three of filters (Hydrocyclone, Sand, and Disc filters) and application of hypo chloride (Ca (OCl)₂ ) 2 ppm as chemical treatment. Generally, physical treatment was more effective than chemical treatment to reduce clogging ratio for Sumael water (LSI). In contrast, for Bazalan water (LSII), the chlorine application was more practical to reduce clogging ratio. The results showed after the period of 320 hr, filtration reduces the clogging ratio for Sumael water (LSI) was 67.77% at clogging ratio 12.51%corresponding to 28.53% at clog

Determining sample size to estimate the mean value of a target (infinite) population is of prime importance to have correct results and conclusions. In general, sample sizes differ as the studied objects differ. Another factor affect sample size is number of replicates or groups. Small objects, such as seeds, grains, and bacterial cell sizes require in general larger sample sizes as compared to large objects, such as human patients, large animals, and large trees. In this short article, a mixture of 12 crosses, maize kernels (k) were mixed to have 12,000 kernels. Sample sizes of 50,100, 150, 200, 250, and 300k were taken to find out which sample size fits the mean of target population (12,000 k). Sample size of at least 100 k and

Phytoremediation is the ability of some plants to bio accumulate, decompose, or transformation of pollutants in soils, water, or air. In the current study, an effort is made to study the effectiveness of free-floating plants to treat simulated industrial wastewater polluted with Lead and Cadmium ions using Azolla Pinnata plant in a lab condition. Free water surface flow constructed wetland were fed with simulated Cd and Pb ions in different concentrations (5, 10 and 20) mgl^-1. Different operating conditions were studied such as; pH, dissolved oxygen, electrical conductivity, temperature, and sodium adsorption ratio to find out the possibility of using treated wastewater for irrigation.
