A field trial on green onion crops in the autumn of 2020 transpired at a private farm in the District Al- Saniyah, Al-Diwaniyah Governorate, Iraq. The presented study aimed at characterizing green onion (Allium cepa L.) plants with NPK fertilization and foliar application of hornwort extract for growth and yield traits. In this experiment, the first factor comprised three NPK levels (0, 50%, and 100%) of NPK (150:100:150 kg ha-1) recommended fertilizer added to the soil, while the second factor included the foliar application of hornwort extract with two different concentrations (0, 20 ml L-1). The experiment in a randomized complete block design (RCBD) with factorial arrangement had three replications. Consequently, the recommended dose of NPK (100%) and spraying hornwort extract at 20 ml L-1 revealed a significant increase in the studied traits, i.e., plant height, length of the longest tubular leaf, number of leaves, fresh weight of tubular leaves, number of bulbs per plant, weight of the bulb, the diameter of the bulb, leaf chlorophyll content, bulb carbohydrate content, leaf carotenoid content, and plant yield. The interactions of both factors also showed a favorable effect on the mentioned traits in green onion.

Abstract A field experiment was conducted on one of the private sector farms in Albuhidari area located in Al-Najaf governorate, Iraq, during the autumn season of 2021. The current research aimed to investigate the influence of polyethylene covering integrated with potassium silicate (K2SiO3) spray on the growth and yield of radishes. A split split-plot system was implemented based on RCBD with three replicates. The field plots were divided into two groups (non-covered plots and covered with low tunnel polyethylene sheets) designated as the main plots. While the two varieties of local radish (white and red) were assigned as subplots, and three concentrations of (K2SiO3) (0, 400, 600 mg.L-1) were assigned as sub-subplots. ANOVA results demonstrated that the main effect of each factor improved radish studied indicators for plant height, number of leaves per plant, leaf dry matter%, root dry matter%, and the root yield per plant. The polyethylene covering provided a physical barrier against cold stress, while the silicon treatments at high concentrations enhanced the plants’ tolerance to low temperatures and improved overall plant growth. Bi-interaction effects were almost significant for some indicators. Moreover, the triple interaction (polyethylene covering + red variety + spray with (K2SiO3) @ 600 mg.L-1) was superior in all indicators except for root dry matter%. The results indicate that polyethylene covering combined with silicon treatments have a significant protective effect on white and red radish plants.

This current research proceeded during the growing season of 2021 at the Al-Nakhil Station, Al-Najaf Governorate, Iraq, to evaluate the response of hybrid tomato (Lycopersicon esculentum) ‘OULA F1’ to foliar application of organic fertilizers NP and calcium. The first factor included spraying phosphorous and nitrogen with three concentrations (0, 1, and 2 ml.L-1), while the second consisted of calcium spray with three different concentrations (0, 1.25, and 2.5 ml.L-1). The experiment was setup according to the randomized complete block design (RCBD) with three replications in a factorial arrangement. The results showed that the organic fertilizer rich in phosphorus at a concentration of 2 ml.L-1 significantly improved the traits, i.e., plant height (49.98 cm), leaf number (34.80 leaves.plant1), leaf area (3775.90 cm2.plant-1), shoot dry weight (156.70 g.plant-1), and leaf content of total chlorophyll (183.19 mg.l00g-1 FW) in comparison with the control treatment. Also, the same concentration of phosphorus revealed superiority in the percentage of N, P, K, and Ca in tomato leaves and fruit yield per plant (1.79%, 0.71%, 2.23%, 1.69%, and 2.89% kg.plant-1, respectively), compared with the control treatment. Moreover, the results further revealed that the organic calcium fertilizer at a concentration of 2.5 ml L-1 realized the highest averages for plant height, leaf number, leaf area, shoot dry weight, leaf N percent, leaf P percent, leaf K percent, and fruit yield per plant by 52.39 cm, 35.27 leaves.plant-1, 3850.20 cm2.plant-1, 175.73 g.plant-1, 1.74%, 0.70%, 2.17%, and 3.12 kg.plant-1, respectively. The foliar application of calcium at a concentration of 1.25 ml.L-1 provided the maximum total chlorophyll (175.03 mg.l00g-1 FW) and Ca (1.74%) in the leaves.

The latest study aimed to assess the response of the broad bean to the magnetically-treated irrigation water and foliar application of nano-seaweed extract for growth and productivity traits. This experiment took place during the growing season of 2020–2021 under field conditions at Al-Najaf Governorate, Iraq. Turkish broad bean cultivar ‘Luz-de-otono’ was grown in a split-plot design by two factors with three replicates. The main plots received magnetized irrigation water with three diverse intensities (zero, 1000, and 2000 Gauss), while the nano-seaweed extract with three concentrations (0, 1, and 2 ml.L-1) in the subplots. On average, the magnetization treatment at 2000 Gauss attained significant improvement in the growth and morphological traits (plant height, branch number per plant, leaf number, leaf area, and total leaf chlorophyll content) and yield traits (pod number, pod weight, plant yield, and total yield), compared with the control that gave the lowest values. Nanoseaweed foliar application at 2 ml.L-1 also revealed a significant increase and improvement in the same growth, morphological, and yield-related traits aforementioned, compared with the control treatment that gave the minimum values. Correspondingly, the interaction between both factors (magnetization intensity 2000 Gauss + Seaweed at 2 ml.L-1) also showed significant effects and provided the highest averages of plant height (36.05 cm), branch number per plant (7.04 branch.plant-1), leaf number (72.19 leaves.plant-1), leaf area (3775.88 cm2.plant-1), and total leaf chlorophyll content (45.47 mg.100 g-1 FW) and yield traits: pod number (19.11 pods.plant-1), pod weight (26.87 g), plant yield (513.49 g), and total yield (11.61 t.ha-1), compared with the control treatment.

Abstract A pot trial was conducted to identify the effect of adding rice organic residues (ROR) to the potting soil and spraying chelated zinc (CZn) on the growth, flowering, and corm characteristics of the Freesia hybrida plant. An RCBD experiment was adopted with two factors and three replicates. ROR comprised three levels (0, 4, and 8%), and CZn included three concentrations (0, 20, and 40) mg.L−1. The findings revealed that applying ROR at 8% and spraying CZn at 20 mg.L−1 significantly increased leaf number, shoot dry weight, total chlorophyll content in fresh leaves, and total soluble carbohydrate content in dry leaves (6.66 leaves. plant−1, 8.76 g DW, 48.79 mg.100 g−1 FW, and 1.50 g DW) respectively. Also, the same treatment combination realized significant results for the number of florets per inflorescence, floret diameter, floret vase life, number of corms per plant, and corm diameter by (12.85 florets. inflorescence−1, 7.03 cm, 8 days, 3.66 corms. plant−1, and 2.33 cm) consecutively. Further, adding ROR at 8% and spraying CZn at 40 mg.L−1 significantly increased the number of inflorescences (5.33 inflorescences. plant−1) and inflorescence length (39.10 cm).
