The effect of different levels of crud fenugreek leaves on lipid oxidation and microbial spoilage of mutton and beef cattle meat postmortem refrigerated storage was examined. Samples meat of mutton and beef cattle were incorporated with crud fenugreek leaves at four different levels 0, 0.5, 1.0 and 1.5 %. Mutton and beef meat in burgers form were subjected to 7 and 10 d postmortem refrigerated storage. Mutton and beef cattle meat marinated with crud fenugreek leaves had significantly lower content of malondialdehyde (MDA) at day 7 and 10 postmortem, respectively. Bacterial counts was lower (p<0.05) in mutton and beef cattle meat contenting crud fenugreek leaves compared to control at 3, 5, 7 and 10 postmortem. Regardless of treatment, postmortem refrigerated storage influenced oxidative and microbial stability of meat. Adding crud fenugreek leaves into mutton and beef cattle meat exhibited effective antimicrobial properties and high antioxidant activity.

The current study included collecting samples of water and soil from three main agricultural sites on Aldanfeeli Valley in Mosul city (North Iraq), where soil samples included two from each location, one for agricultural soil watered with untreated Valley water, and the second sample was from the adjacent uncultivated soils. A fourth site was chosen for the purpose of comparison at the end of Aldanfeeli Valley where the cultivated soil was watered with water of the Tigris River before the confluence of the River Valley.
In addition to estimating the concentrations of heavy metals (Zn, Cd, Pb, Cu, Fe) in both water and soils, the present study aimed to identify some chemical and physical properties of the soils, namely: electrical conductivity, pH, organic matter, calcium carbonate, cations and anions, soil texture, and specific gravity.
Despite the fact that the waters of Aldanfeeli Valley are poor for agricultural purposes in terms of salinity and total concentrations of both chloride and half of sulphate ions, the results showed that all soils do not suffer from the problems of salinity and alkalinity. Regarding the concentrations of heavy elements (Zn, Pb, Cd, Cu, Fe), their averages in the cultivated soils (23.86, 5.98, 75.14, 7.53 and 140.18) p.p.m. respectively, were higher than their counterparts in non-cultivated ones (18.70, 5.47, 36.82, 6.17 and 114.63) p.p.m. respectively. All soil samples especially the cultivated ones indicated higher concentrations than those of the irrigation waters (6.47, 4.87, 8.87, 2.27 and 7.07 p.p.m. respectively. The iron recorded at all sites higher means when compared to the rest elements. These were (140.18 and 114.63) p.p.m. in both the cultivated and noncultivated soils respectively. In both the second and the third sites of the cultivated soils; lead concentration averages of (114.25 and 91.06) µg g-1 respectively, have exceeded its standard limit (50 µg g-1); whereas, cadmium concentration averages in these two sites were (8.23 and 6.88) µg g-1 respectively, have exceeded its critical limit (5 µg g-1).

This study was conducted in the lath house of the Department of Horticulture and Landscape Design/ College of Agriculture/ Tikrit University during the growing season of 2017 to investigate the effect of magnesium application and the foliar spraying of both gibberellic and salicylic acids on the vegetative growth characteristics of peach saplings CV. Miski, aged one year which were grafted on Apricot seedlings. Magnesium was added in three concentrations (0, 50 and 100 mg.litre-1) and was labelled as Mg0, Mg1 and Mg2 consecutively. The gibberellic acid was sprayed in three concentrations (0, 50 and 100 mg.liter-1) and labelled as GA0,GA1 and GA2 consecutively. Besides the salicylic acid was sprayed with the following concentrations (0, 100 and 200 mg.L-1) and labelled as SA0, SA1 and SA2 consecutively. All these processes were performed starting from April 10 three times, with a time interval of three weeks. The experiment was performed based on the split-plot system in Randomized Complete Block Design (RCBD) in which the various magnesium concentrations were added to the main plots and both the gibberellic and salicylic acids were applied to the subplots.
The results showed that the addition of magnesium has positively increased the main stem diameter, single leaf area, total leaves area per plant and the relative chlorophyll concentrations in leaves.
The height and the diameter of a sapling, length of the branches, leaf area and total leaves area of sapling were increased as a result of foliar spraying with gibberellic acid.
The spraying of salicylic acid has a positive effect on the saplings’ characteristics (leaf area, total leaves area and relative chlorophyll concentration in leaves).
The dual or triple interaction treatments between the three studied factors had the positive results in most characteristics were investigated.
