ABSTRACT
This study was aimed to evaluate the effectiveness of some of chemical (salicylic acid and calcium chloride) and biological factors (Trichoderma harzianum) and the extract of tomato plant debris on resistance induction in tomato plants against Fusarium wilt disease Fusarium oxysporum f.sp lycopersici and on growth parameter of this crop.
The effect of pre-inoculation treatments of biotic and abiotic inducers to tomato plants in green house conditions against F. o. f. sp. lycopersici , revealed that SA, CaCl2 and T. harzianum which applied three days before inoculation with the pathogen (FOL), were completely prevented disease incidence and disease intensity in tomato plants. Extract of tomato debris revealed less inhibitory effect on percent infection and disease intensity of wilt disease which reduced to 35.24 and 20.94 respectively by un-sterilized extract and to 100% and 90.94% by sterilized extract compared with that treated with pathogen only.
In contrast, the use of chemical and biological factors, led to increased growth parameters, height, fresh, dry weight of shoots and roots and chlorophyll content in tomato plants treated with SA, CaCl2 and T. harzianum in comparisons with that in untreated plants.

Abstract
A plot experiment had been carry out in Qadisiyah University / Faculty of Agriculture on November 4014 to study the effect of four levels of irrigation water magnetically on some chemical characteristics of the soil and the barley growth cultivated in saline soil (Silty Clay Loam)which put in pots 18 kg .Irrigation water treatments including use Magnetic devises which have capacity 500,1000 and 1500 gauss, as well as the control treatment. The irrigated with a treat water magnetically when the soil lost 30% from available water. Results of statistical analysis showed that the treatment water magnetically did not significantly affect all the characteristics which are (EC,PH,SAR, the percentage of total calcium carbonate, gypsum dissolved, sodium dissolved, calcium dissolved, magnesium dissolved, potassium dissolved, chlorine dissolved, bicarbonates dissolved and sulfate dissolved) compared with irrigation water Control.

Abstract

This experiment was conducted at the station of sheep and goat research’s / the state board of agricultural research ,the artificial Insemination Department belongs to the Ministry of  Agriculture and in the High Institute of Infertility Diagnosis and Assisted Reproductive Technology at Al-Nahrain university, Baghdad, Iraq to investigate the effects of  cryopreservation on some ram semen characteristics. Six Turkish Awassi rams were used for semen collection and evaluation. several samples of ram semen were collected and evaluated for Volume, pH,color,Sperm concentration ,Mass activity and individual motility using computer assisted semen analysis (CASA) Dead and abnormal sperm and DNA fragmentation index (DFI). Then the semen was diluted 1:19(semen: diluents v/ v) using a Tris diluents and subjected into slow cryopreservation program .The semen samples were assessed after freezing-thawing. Cryopreservation causes a clear decadency in some parameters of ram semen .Result shows that there was a significantly (p< 0.01) affect of cryopreservation on the dead sperms percentage (31.6 ± 1.92), individual motility(IM)(31.33± 1.20%) and DNA fragmentation index (DFI) (29.83± 4.45%).

Abstract

The Experiment carried out to study the effect treatment of acid salicylic in improving wheat and chickpea plants in the germination stage and seedling growth under salt stress during the agricultural season 2015-2016, designed the experiments according to the randomized complete design and included two types of crops: the first crop of wheat (Abu Ghraib) The second crop is chickpea plant (local variety) and the experimental work involved the first laboratory to determine the optimal concentration of salicylic acid (SA) in germination and growth of seedlings crop wheat, chickpeas stage was measured by the percentage of germination and length of shoot and root (mm) after the 3.5.7 days from sowing .The Experiment carried out by using sodium chloride, according to randomized complete design (0ds | m, 2ds | m, 4dS | m, 6dS | m, 8dS | m) by three replications , the percentage of germination of the length of the shoot (cm ), root length (cm), shoot fresh and dry weight (g), the weight of root wet and dry (g) after 20 days from sowing. the relative water content, chlorophyll concentration in the leaves were measured. the results showed the following: increased concentrations of salt led to decrease percentage of germination reached 61% and 46% and the average of : shoot length reaching 0.7 mm and 0.8 mm, root length14-mm and 20-mm, wet weight73 g and 85 g, dry weight 220 g and 248 g in wheat and chickpeas respectively, as well as soak seeds by acid, salicylic before planting a concentration of 1.5 mM reduced the negative effects of the concentration of high-salt, and improved values for all the studied indicators and the percentage increase follows: the average length of the shoot 73 and 37% , a radical 35 and 53.57% , an average wet weight of the root 27.05 and 43.83% , the average shoot 45 and 50% , the average dry weight of the root 27.69 and 45.2% , the average shoot 41.9 and 34.78% , the average relative water content of 10.98 and 28.35% the average concentration of chlorophyll 34.28 and 40.9% in wheat, chickpeas, respectively.

Volume 4, Issue 1, 2016 Page 100-119

Abstract

Experiment was conducted at the fields of Agricultural College- University of
Basrah, Karmatt-Ali campus according to randomized complete block design (RCBD) with a split plot arrangement of the treatments to study the effect of three forward speeds (1.30, 0.80, 0.41 m.sec-1) and three plowing depths (25, 15, 10 cm) on the field performance indicators i.e. draft force ,drawbar power , specific resistance, mean weight diameter (MWD), plowing efficiency and degree of plowing in silty – clay soil. The forward speeds was the main plots and tillage depths as sub-main plots. The soil bulk density was (1.30 Mg.m-3) and content moisture was (10.50 %). The results showed that the increase in forward speed from 0.41 to 1.3 m.sec-1 led to a significant increase in draft force, drawbar power ,specific resistance ,plowing efficiency by (20.40, 106.62, 429.44, 109.45%), respectively, while the mean weight diameter (MWD) and the degree of plowing were decreased by (4.7 0.36%), respectively .While increasing plowing depth from 10 to 25 cm led to a significant increase in draft force, drawbar power and mean weight diameter (MWD) by (58.97, 49.50 , 82%) respectively and decreasing in specific resistance,
plowing efficiency and degree of plowing by (46,96 ,36.5, 48.8 %) respectively. The interaction between forward speed and plowing depth was effected significantly on the field performance indicators. The highest level in draft force and drawbar power were 24.45 kw 22.84, kN respectively at forward speed 1.3 m.sec-1 and plowing depth 25 cm and highest level in specific resistance was 115.95 kN .m -2 .The best value of mean weight diameter (MWD) was 27.16 mm at forward speed 1.3 m.sec-1 and depth 10 cm and best value of plowing degree was 87% in forward speed 0.41 m.sec-1 and the depth of plowing 10 cm while the best plowing efficiency. value was 81% at forward speed 1.3 m.sec-1 and depth of plowing 10 cm.
Key words: chisel plow, draft force, specific resistance, draft power, mean weight diameter, degree of plowing, plowing efficiency.

Abstract

Conducted a field survey using a questionnaire for nine apiaries distributed in northern, central and southern Dhi -Qar province, for the period from 1/2 / 2013- 05/01/2014 The results showed that the main reasons for the deterioration of beekeeping in the province of pests and vegetation and the failure of partitions and the use of pesticides and specialization as deterring the percentage of 100% and 80%, 20% and 60% and 44%, respectively, and had lesions influential role as a bird Abu-Khudair Iranian form of damage, followed by the biggest wasp. It comes lice blind third class, followed by the major wax worm varying degrees depending on the cells strength and there are other lesions accounted few cases, as in the rot disease brood either partitions failure was 20% and that the best time to hold them from 15/2 to 1/3 as the success rate reached a 80And amounted to 70% for the period from 1/4 to 15/4 either vegetation was 20% and the damage was clear. Because the cultivated that cover the needs of the bees from the nectar and pollen.
