A field experiments was conducted to evaluate the effect of soil amendments with organic and inorganic fertilizer (chemical fertilizer) on the potassium availability, improve growth and yield of chickpea (Cicer arietinum L). In this experiment each organic and inorganic fertilizer (NPK 15: 15: 15) was added as amount equivalent to potassium (K) at levels 0, 12.5, 25, 50, 100 kg K ha^-1. Results revealed that there were significant effect of application organic and inorganic fertilizer on soluble and exchangeable K in soils, the application of organic and inorganic fertilizer at level of 100 kg K ha^-1 increased the soluble K from 4.1mg L^-1 to 7.99 a

This study was designed to investigate the influence of pre-estrus (PE) synchronization and post-mating (PM) vitamins AD₃E treatment on the reproductive performance of Awassi ewes raised at four Iraqi provinces. Seventy six Awassi ewes were randomly divided within each province into two groups. The first group (n=15, except for Karbala, n= 11) were im injected with five AD₃E injections (150 IU / dose), biweekly interval. The 1^st injection was 1.5 months PM, while the 2^nd and 3^rd injections were at the time of progestagen-impregnated vaginal sponges insertion. The 4^th injection was at the time of the vaginal sponge’s removal, whereas the 5^th injection w

The current study prioritized certain popular local cereal species like Wheat, Oat, Rye and two local Barley varieties known as Aksad and Amal to extract their β- glucan using alchemical methods. The results of this study indicated that rye contained the lower percentage of β-glucans (0.756%) whereas, both types of barley Aksad and Amal contained highest amount (9.489%) and (7.395%) respectively. However, the results showed that the crude extracted of   β- glucans from wheat, oat, rye, barley (Aksad) and barley (Amal) were 0.373,1.409, 0.26, 2.287 and 1.855 g/100g flour respectively which was reflected the efficiency of extraction process which ranged between 8.83 ± 0.01for wheat to 34.39

This study was designed to confirm the effect of different concentrations of water extract for stevia leaves on lowering blood sugar, cholesterol and other blood traits in diabetes-induced mice. Forty mice with weights ranging 30-35 mg per diabetic were injected intravenously into the gastric tube except for control group (non-diabetic control) and were left for one week to confirm their diabetes. The animals were divided randomly into 5 groups with 8 mice per group; animals were given in group 1 (non-diabetic control) and group 2 (diabetic control) fed standard diet with water supply, while groups 3, 4 and 5 were fed standard diet and different concentrations 300, 400 and 500 mg / dl / day respe

The aim of this study is to evaluate the effect of barley consumption on sugar reduction in diabetic patients in male and female rats. The mice were divided into six groups with 10 mice per group. The mice injected the substance with 200 mg / kg body weight to induce diabetes. The study included 60 mice of both sexes, injected with aloxane and a dose of 200 mg / kg body weight to induce diabetes. The first group was represented by the control group as its members took standard food from the experimental animal food. The second group, which represents the induced control group as its members took the general measure of food, but injected the substance of the aloxane for comparison. While the third and fourth group

Crop growth modelling is one of the important sciences in field crop sciences for it helps to reduce time and effort in searching for a fact or result. This article was dealed with a formula to predict maize ear grain weight when plants still standing on farm. Two genotypes of maize were used in this trial, a hybrid of feed maize was used in 2018 and an open-pollinated cultivar of pop corn in 2019. Ear length and diameter were measured on 50 randomly taken plants of full seed – set before harvest .Ears were harvested later, air dried ,threshed and weighed, then yield adjusted to 15% moisture .Ears were considered as cylinder ,and volumes of each ear were calculated .Date of observed ear grain weights and their volumes were anal

The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is one of the most widespread pests worldwide on host plants, including fruits, vegetables, and ornamental plants, in open fields or under greenhouse conditions. Their damage is not only caused by sucking the juice from plant tissue but also by their ability to transmit many viruses. In this study, A. gossypii individuals were collected in the seasons of 2022 and 2023 in order to conduct a series of bioassay experiments to evaluate six essential oils, which were Cloves (Syzygium aromaticum), Thyme (Thymus vulgaris), Rosemary (Salvia rosmarinus), Lavender (Lavandula coronopifolia), Coriander (Coriandrum sativum),

The study was conducted to investigate symbiosis and node-forming ability of Mesorhizobium bacteria in chickpea (Cicer arietinum L.) growth under challenging environmental conditions. Nodules were collected from wild and cultivated chickpeas in the Kurdistan Region. Endophytic bacteria associated with their roots were isolated and characterized. All the 30 isolates, were found to be gram-negative with smooth, circular colonies. Most isolates (80%) were mucoid, while 20% were not and produced green colonies on bromothymol blue. Half of the isolates 50%) grew best in alkaline pH (6.6-10.5), 26.6% thrived in acidic pH (3.5-5.5), and 20% preferred neutral pH. Regarding salt tolerance, 63% of the isolates grew well in 0-4% N

This study was amid to assess the radical scavenging activity, reducing power and total antioxidant capacity of elastin enzymatic hydrolysate (EEH) which prepared by treating common carp bulbus elastin extract with elastase for 10 hours at 40 C°.
