    (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.

    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%).
