    (Estonian Academic Agricultural Society, 2021) Al-Zubaidi, Mohammad Salman Kareem; Bader, Basem Rahem; Abood, Mohammed Ali; Hamdi, Ghassan Jaafar; Al-Afraji, Hassan Rashid Jassim
    A field experiment was carried out within the randomized complete block design in the agricultural season 2020–2021. The experiment included two factors, the first factor was solid chelated iron (S0, S1, and S2 at concentrations 0, 100, and 200 ppm, respectively), which was added to the soil. The second factor was liquid chelated iron (L0, L1, and L2 at concentrations 0, 2, and 4 ml L–1 respectively), which was spraying on the plants. The results showed that the stem diameter, number of pods, and total yield were significantly affected by adding the 100 ppm iron solid chelated treatment (18.36 mm, 25.74 pod plant–1, 5.01 Mg ha–1 respectively). While 200 ppm treatment had the highest plant height (30.10 cm, yield (771.35 g plant–1), seeds (6.18 per pod). The treatment of 4 ml L–1 liquid chelated iron treatment had the highest plant height (128.55 cm), biggest stem diameter (18.63 mm), highest pods per plant (25.45), yield (755.98 g plant–1), total yield (4.80 Mg ha–1), pod length (24.87 cm), pod weight (28.14 g) and the number of seeds per pod (7.88). The use of the interaction between solid and liquid chelated iron improves the vegetative growth and yield of broad beans.

    Effect of water deficit and foliar application of amino acids on growth and yield of eggplant irrigated by two drip systems under greenhouse conditions
    (Estonian Academic Agricultural Society, 2020) Bader, Basim Raheem; Abood, Mohammed Ali; Aldulaimy, Saad Enad Harfoush; Al-Mehmdya, Shuker Mahmood Hassan; Hamdi, Ghassan Jaafar
    Water deficit in semiarid areas limits eggplant (Solanum melongena L.) production and growth indicators. Suitable drip irrigation system and foliar application of amino acids may help overcome water deficit. In this work, the effects of drip irrigation system [Grand flow regulators (GR) and T-Tape], water deficit (50, 75, 100% based on field capacity) and foliar application of amino acids at 0, 100 and 200 mg L–1 on water relation of leaf's, yield and field water use efficiency (WUEf) of eggplant were studied. The experiments were arranged in a split-split plot design within a completely randomized distribution each repeated three times. GR irrigation system treatment produced the highest relative water content (RWC), most yield (TY), WUEf and the lowest of water saturation deficit (WSD) which were 74.71%, 6.50%, 5.97 t ha–1, 2.11 kg m–3 and 23.09%, respectively. The lowest water uptake capacity (WUC) and relative membrane permeability (RMP) was obtained in T-Tape irrigation system treatment (0.43% and 59.45%, respectively). The 100% irrigation level revealed higher RWC (79.32%), WSD (7.38%), most TY (6.93 t ha–1), the least of WSD (18.00%), WUC (0.28%) and RMP (39.40%). The maximum of WUEf (2.37 kg m–3) was obtained from 50% irrigation level. The foliar application of 200 mg L–1 Amino acids rate resulted in significantly maximum RWC (81.50%), WRC (7.19%), TY (6.75 t ha–1) and WUEf (2.51 kg m–3) and least WSD (15.88%), WUC (0.33%), RMP (52.02%). GR drip irrigation system is best for water use efficiency; 200 mg L–1 Amino acids produced the best response for most studied traits.

    Influence of moisture depletion and surface drip irrigation style on some soil hydraulic properties and potato crop
    (Estonian Academic Agricultural Society, 2019) Aldulaimy, Saad Enad Harfoush; Salman, Adil Khairullah; Abood, Mohammed Ali; Hamdi, Ghassan Jaafar
    This study aimed to determinate the impact of soil moisture depletion and surface drip irrigation style on some soil hydraulic properties such as infiltration, hydraulic conductivity, application efficiency, and water use efficiency for potato crop. A field experiment was carried out in a site located north east Ramadi, Iraq. The study consists of two factors: the first factor was two levels of moisture depletion percentages 25 and 50%, while the second factor includes two surface drip irrigation styles, which were traditional surface drip irrigation and partial drying surface drip irrigation. Consumptive use for potato plant reached 32.05 cm during the growing season. Results showed a significant influence for the treatments on application and water use efficiencies as well as on infiltration and soil hydraulic conductivity. The combination of the treatments partial drying drip irrigation style and 25% moisture depletion percentage can be recommended to achieve the best irrigation management for potato plant, which improve soil hydraulic properties and meet the best plant response in same time.

    Response of onion growth and yield grown in soils of semi-arid regions to foliar application of iron under water stress conditions
    (Estonian Academic Agricultural Society, 2021) Gar, Laith Farhan; Bader, Basem Rahem; Al-Esawi, Jabbar Shihab Eyada; Abood, Mohammed Ali; Sallume, Mohammed Obed; Hamdi, Ghassan Jaafar
    Iron (Fe) is one of the major micronutrient crucial for plant growth, yield and quality. A field experiment was conducted in Fallujah, Iraq during the autumn season in 2019 to study the effects of foliar appli-cation of iron and irrigation levels on growth characteristics and yield of onion (Allium cepa L.). A two-factorial experiment arranged as a rando-mized complete block design with three replications was conducted in loamy sand soil. The two factors were water stress (50, 75, and 100% con-sumptive use of water) and iron concentrations (0, 100 and 200 mg L–1). The results show a significant decrease in plant height, number of bulbs, total chlorophyll content, dry mass, iron content in the leaves, the average weight of bulbs and total yield of bulbs by reducing irrigation levels from 100 to 50% of the water supply. Application of iron by foliar spraying significantly increased most of the aforementioned traits. The interactions between iron and irrigation levels were significant in most of the measured traits. The interaction between 100% water supply and 100 mg L–1 of iron achieved the highest total yield value (4 332 Mg ha–1) while the combina-tion of 75% of water supply and 100 mg L–1 of iron gave the highest value of water use efficiency (84.7%).

    Tecamin flower® foliar application to alleviate water deficit effects on growth, yield and water use efficiency of tomato
    (Estonian Academic Agricultural Society, 2018) Al-Shammari, Aziz Mahdi Abd; Abood, Mohammed Ali; Hamdi, Ghassan Jaafar
    During drought chemical elements in a dry fertilizer go into solution in the soil with difficulty and the nutrients are less available to the plant. Foliar fertilization with Tecamin flower®, could compensate for nutrient deficiency due to water deficit. This study was designed to observe the effects of different application rates of foliar application of Tecamin flower® on growth, yield and field water use efficiency (CWUE) of tomato under water deficit. The field experiment was conducted from March till July 2016 at the teaching and research farm of Diyala University, Iraq. Performance of tomato genotype 'Bobcat', 'Finenss' and 'Hadeer' was assessed by foliar application of Tecamin flower® at (0 and 2.5 mL L-1) and two irrigation levels (50 and 100% based on field capacity). The results showed that chlorophyll content, fruit weight, yield per plant, total yield and CWUE were significantly affected by genotype and irrigations levels and application of Tecamin flower®. 'Bobcat' genotype has the highest value of plant yield (3.39 kg) and total yield (90.19 t ha-1). 'Finenss' has the highest values for number fruit per plant (40.75), CWUE (75.37 kg m-3) and the minimum leaf proline content (2.584 mg g-1). Plant irrigated at 100% had the highest value of number fruit (35.27 fruit), most yield per plant (3.53 kg), total yield (94.02 t ha-1) and minimum leaf proline content (2.557 mg g-1). The highest CWUE (84.50 kg m-3) were at 50% level. Plant treated at 2.5 mL L-1 Tecamin flower® had most fruit/plant (37.61) yield per plant (3.73 kg), total yield (99.16 t ha-1), CWUE (85.22 kg m-3) and minimum leaf proline content (2.437 mg g-1).
