“…An experiment was conducted in a plastic house measuring 9 x 44 m at the site of the College of Agriculture / University of Anbar for the fall season 2022 inside a greenhouse with dimensions to know the effect of biofertilizer Mycorrhizaee and Azotobacter as a combination with phosphate Rock) with the addition of vermicompost tea (spray on the plant) in the concentration of the major elements NPK in the soil after planting and in the leaves of the cucumber plant during the planting season (flowering stage). The soil used in the greenhouse is sandy loam with high water permeability and poor in nutrient content, the soil was plowed twice and adjustment and leveling operations were carried out, then soil samples were taken randomly for multiple sites of the surface layer to a depth of 0-30 cm, chemical and physical analyzes of the soil were carried out as shown in Table (1).…”

“…There are other organisms that increase the availability of phosphorus and many other nutrients in the soil, including root fungi (mycorrhizae), which is a secondary root of the plant that works to increase the absorption of water and nutrients through the extension of its hyphae to several meters, as well as for its secretion of growth hormones and enzymes and its ability to bio-control diseases. The use of microbial bio-fertilizers is therefore an effective and viable option [1,2]. Organic fertilizers are very important for microorganisms and soils alike.…”

An experiment was carried out inside a greenhouse (sandy loam soil) at the College of Agriculture / University of Anbar to investigate the effect of Vesicular-Arbuscular Mycorrhizaee, Azotobacterchroococcum and Vermicompost tea on the concentration of NPK macronutrients in soil and cucumber plants. A factorial experiment consisting of two factors was designed for this purpose: the first factor is a combination of mycorrhizae (M) with 35 g plant-1, azotobacter (A) bacteria 16 ml plant-1 with a microbial density of 2.2 x 109 cfu ml-1 and phosphate Rock (R) with 40 g plant-1, added with half of the mineral fertilizer recommendation each individually with its interactions, The second factor is the addition of three concentrations (0, 5, 10%) of vermicompost tea sprayed on the plant. The experiment was designed with a completely randomized block design (RCBD) with three replications. Cucumber seeds were planted on 15/9/2022 and service operations were conducted for the crop and the experiment continued until 15/12/2022. Concentrations of nutrients were measured in the soil after harvesting the crop as well as in the leaves of the plant. The results of the research proved that the use of mycorrhizae, azotobacter bacteria and phosphate Rock with half the mineral recommendation (MAR) and spraying vermicompost tea at a concentration of 10% are the best in increasing the concentration of nutrients in the soil and plant and revealed significant differences compared to mycorrhizae or azotobacter or vermicompost tea individually, so this treatment gave the highest concentration of available nitrogen (AN) (56.37 mg kg-1 soil), the highest available phosphorus (AP) (16.34 mg kg-1 soil), the highest available potassium (230.3 mg kg-1 soil), and gave the highest percentage of nitrogen in the leaves (NIL) (2.80%), The highest percentage of phosphorus in the leaves (PIL) (0.40%), the highest potassium in the leaves (KL) (1.95%), followed by the treatment of adding mycorrhizae with phosphate Rock and half the mineral recommendation (MR) with vermicompost tea at a concentration of 10%, then the treatment of adding mycorrhizae with azotobacter bacteria with half the mineral recommendation (AR) with 10% of vermicompost tea, then the treatment of mycorrhizae with phosphate Rock plus half the fertilizer recommendation (MR) with 10% of vermicompost tea, then the treatment of mycorrhizae with azotobacter plus half of the fertilizer recommendation (MA) with 10% of vermicombe tea. Then the two treatments of mycorrhizae (M) and azotobacter (A) separately, while finally came the treatment of chemical fertilization (S), which gave the lowest values to the mentioned properties in the soil and plants.

“…The addition of vermicopost tea sprayed on the vegetative system causes an increase in the permeability of the stomata, which leads to an increase in the absorption of macro-and micronutrients, vericompost tea stimulates the growth and elongation of cells, which is reflected in increasing the root system, increasing the amount of nutrients absorbed, and increasing the vegetative system because it contains plant growth regulators such as auxins, cytokines, abcisic and gibberellins [3]. All these specifications gave the plant better growth and higher production due to the increased availability of nutrients in the soil and then increased their concentration in the plant, which was evident through the use of vermicompost tea, especially at the highest concentration (10%) and was more influential and positive when interacting with the bio-fertilizers used in this research [16].…”

“…Vermicompost is one of the best organic fertilizers recently, which has a very important impact on increasing plant growth and yield, improving soil properties and creating a healthy and safe ecosystem for food processing. An extract of vermicompost called vermicompost tea can be added to the soil or sprayed on the plant and is considered a supplement to mineral fertilization as it contains nutrients necessary for plant growth 1252 (2023) 012058 IOP Publishing doi:10.1088/1755-1315/1252/1/012058 2 and is also used in biological resistance as an alternative to chemical pesticides that negatively affect public health and the environment, giving ideal properties in terms of the quality of the yield and the original taste desired by the consumer free of environmental and health pollutants [3]. Cucumber plant Cucumis sativus L belongs to the Cucurbitaceous family, which is one of the important vegetable crops in most countries of the world, including Iraq, and it is widespread, especially in protected agriculture, as it has nutritional, economic and health value [4].…”

A field experiment was conducted at the second research station of the College of Agriculture, Al-Muthanna University, using a mixed soil. The objective of the study was to investigate the impact of varying quantities of biochar and organic fertilizer extract on the availability of nitrogen (N), phosphorus (P), potassium (K), iron (Fe), and zinc (Zn) elements in the soil.The experimental design encompassed the incorporation of four distinct biochar levels (A0, 0%), (A1, 1.5%), (A2, 2%), and (A3, 2.5%), which were applied proportionally to the soil volume. Additionally, four levels of organic fertilizer extract (0, 20, 40, and 80) liters per hectare (B0, B1, B2, and B3) were implemented. A factorial experiment was employed inside a randomized complete block design (RCBD) framework, consisting of three replications.The means were subjected to a Least substantial Difference (LSD) test at a significance threshold of 0.05. The findings indicated substantial disparities between the application of biochar and organic fertilizer extract, as well as their interaction, in relation to the levels of accessible nitrogen in the soil.Moreover, notable disparities were observed regarding the incorporation of biochar and organic fertilizer extract in relation to the accessibility of phosphorus within the soil. Furthermore, the introduction of biochar and organic fertilizer extract, as well as the interplay between these two factors, exhibited a substantial impact on the availability of potassium within the soil. Furthermore, the use of charcoal and organic fertilizer extract had a notable impact on the accessibility of iron and zinc within the soil.
