Abstract

This investigation was carried out during growing season (2015 – 2016) on Strawberry (Fragaria X ananassa Duch) Tioga cv. Planted in the farm of college of Agriculture, university of Duhok, Kurdistan regions / Iraq to study the effect of GA3 with concentration (0, 100, 200 and 300 mg.L-1), and Zinc with concentration (0, 2 and 4 g.L-1), on growth, yield and quality of strawberry plant. According to the obtained results the GA3 and Zinc spraying especially at (300 mg.L-1 and 4g.L-1) respectively caused to improve most of the studied parameters, except of total acidity, decreased with increasing GA3 and Zinc concentrations. The interaction between GA3 and Zinc at high concentration resulted in the maximum values of leaf area (30.81cm), leaf chlorophyll content (42.53 SPAD), number of fruit per plant (21.07), yield (269.63g.plant-1), Total soluble solids (8.00 %) and anthocyanin (25.43 mg.100-1 g F. Wt).

Abstract

This study was carried out during the Agricultural season 2016 -2017 in the College of Agriculture/ University of Dohuk /Kurdistan region/ Iraq to study the effect of spraying Humic acid at three concentrations i.e. (0, 9 and 18ml.L-1on four cultivars of potato(Solanumtuberosum L.) i.e.(Sifra, Ravila, Silvana and Fabyoula ) that grown under plastic houses conditions. The results indicated that the all cultivars was good in vegetative growth, quality and yield characteristic especially cultivars Rvillo that gave high yield per plant and per square meter significantly, compared with other cultivars. Also spraying plant with a concentration 18ml.L-1 of humic acid with all cultivars gave goodresults especially in Ravillo cultivars compared with unsparing plant that gave the lower yield and less tuber number per plant.

Abstract

A total number of 300 unsexed Japanese quail chicks one day old were randomly distributed in the metal cages to determine the optimal age of sexual activity for quail in Iraq by studying the growth and development of the gonads pre-to post sexual maturity. Data were collected during 4, 6, 8 and 10 weeks. Steroids hormone and gonads and oviduct development were studied. Highest testosterone and estrogen hormone levels were recorded on 8 and 10 weeks of age. Left and right testis weight, height, width and volume were recorded highest values on 8 and 10 weeks compared with 4 and 6 weeks . Histological parameter of testes sections indicated a complete development for a seminiferous tubules beginning 8 to 10 weeks . Ovary weight with follicles and oviduct weight were given highest values at 10 weeks old. It has been concluded that the optimal age of sexual activity for quail in Iraq could be situated around 8 weeks.

Abstract

This research was done in it in the laboratories of department of animal production/agriculture college/Tikrit university from 2/12/2016 to 2/2/2017 the beef meat loin samples collected from the butchers shop. Then the muscle (longissimussdorsi) separated for use in the manufacture of jerky. The meat dried in the oven after treated with some additives divided into four treatments: control treatment1(without additions) , treatment2 (Soya Sauce added) , treatment3 (special spices added) , treatment4(sweet chili sauce added). The moisture and protein percentage of jerky pieces were measured then panel test was conducted by specialized professors in the department . The results showed a significant differences in moisture contents between four treatments where the percentage was low in the third treatment than the others (23.45±0.45)% also the control treatment which was (25.16 ±0.22) %. protein percentage, the results indicated that there was a significant decreased in the protein percentage for treatment 2 and 4 which were (64.94±0.28)% and (65.02±0.74)% respectively . while this percentage was increased significantly in1 and 3 treatments ( 67.02±0.33)% and (68.52±0.11)% respectively. For the PH value, the results indicated that there was a significant decreased in the pH value for treatments 2,3 and 4 (5.66±0.04)(5.59±0.00)(5.71±0.01) compared to the control treatment which was (5.93±0.03). For the panel test, the results indicated that there was no significant differences in rancidity except accounting differences only where treatment 4 was superior than the other treatments . as for the color, treatment 2,3 and 4 showed significant differences for the desired color of the Jerky by the consumer as it reached (4.11±0.63) (4.74±0.17) and (4.90±0.62) respectively compared to the treatment 1 (3.12 ± 0.22). For the tenderness, there was no significant differences between the four treatments where the tenderness was decreased for all treatments. Finally, for the general acceptance, treatment 1 and 3 were superior as it reached (4.94±0.71)(5.00±0.65) respectively compared to treatment 2 and 4 as it reached (3.11±0/61)(4.28±0.58).

Abstract

The study was carried out in the field of Agriculture College, Duhok University in 2015-2016 growing season to study the growth and yield of four different wheat cultivars (Adana99, Iraq; locals, Zinzbar and Nigal; newly introduced cultivars) using different methods of fertilizers application; fluid seed treatment in ecoZinc, foliar ecoZinc (Black Rocks company, Turkey 0.01Zn), in addition to traditional NPK and control treatments under rain fed conditions of Duhok Governorate. Randomized complete block design was used with four replications. The results showed that Adana99 and Iraq surpassed new introduced cultivars in field emergence and plant height, while the new cultivars were superior in some of spike traits in addition to harvest index but inferior in 1000 grains weight which was the crucial characteristic for reducing the seed quality for these two cultivars as compared to the locals in spite of their superiority in final grain yield and above ground biomass. Regarding fertilizers application, ecoZinc in both fluid and foliar ways were not significant on most of growth characteristics but the spike density enhanced significantly; seed yield was increased significantly (4.6 t.ha-1) in fluid seed treatment in ecoZinc. The newly introduced wheat cultivars are not recommended under Duhok environment conditions due to their late in maturity which consequently effect final seed quality and quantity due to high temperatures at the end of the season.

Abstract

Some chemical and physical properties in soil- water interface in ponds of fish rearing in Duhok city Iraqi-Kurdistan region in summer 2014 such as (redox potential, exchange acidity, total and active calcium carbonate, soil pH and salinity, cation exchange capacity, particle-size distribution, Olsen extractable phosphorus, water total alkalinity, hardness, dissolved oxygen and water-extractable phosphorus) were studied to determine the impacts of variation in these properties on the fish biology and survival in the pond. Result showed that the clayey and very low permeable of bottom soil of pond was a suitable condition for anaerobic respiration, as a result of producing organic acid and alcohol, formation of hydrogen sulfide, nitrite, manganese, ferrous iron, and methane that makes hard poisonous conditions which negatively affect on fish survival and growth, it reduced the concentration of dissolved oxygen in the water of pond to 5.96±1.0 (mgL-1)..In addition long days, (16 hour), and high temperature degree ,40-50C°, during summer season, and high fertilizing led to increase the accumulation of organic matter (%) 5.84± 1.53 that serve the raw material of anaerobic respiration leading to high mortality and sensitivity to disease among fish in the pond.
