ABSTRACT
The study was carried out during the 2021 spring planting season at the Fallujah palm station belonging to the Department of Horticulture, the Ministry of Agriculture, in gypsum soil to study the Impact of organic Fertilization and inoculation with P.sudomonas bacteria, Trichoderma harzanium and Mineral fertilization on the growth and yield of potatoes of Burren variety, Experiment included three factors. The addition of fertilization recommendation by 100% ( M100) led to a significant increase in the content of major nutrients (N, P, K) in the vegetative part, which amounted to 1.35, 0.25 and 1.42 percent, respectively, and in the tubers which amounted to 1.22, 0.21 and 1.28%, respectively. And the starch in the tubers reached 12.89 g. plant-1, while adding half of the Fertilization recommendation (M50) gave the lowest rates for the traits mentioned earlier. The double and triple interactions gave significant results in growth characteristics, yield and mineral content.
Keywords: Potatoes, Organic fertilization, Bio-fertilizations, Mineral fertilization, yield.
INTRODUCTION
The potatoes (Solanum tuberosum L.), which belong to the Solanaceae family, are the third food Yield after wheat and rice. It is also the most critical type of yield because it contains a quantity of protein, starch, and vitamins 4 Adding organic matter to soil increases the activity of soil biology, as microorganisms decompose these wastes in the process of mineralizing the organic matter consisting of carbonic acid, which increases the readiness of the elements and reduces the degree of soil interaction, and organic matter may accumulate in the soil (SOM) as a result of the decomposition of waste The plant material that is added to the field soil from the residues of agricultural Yields, and organic materials can be added that are secretions from tree leaves, root secretions and the remains of decomposing soil organisms 2
Bio-fertilizations are one of the modern agricultural applications, as they contain many microorganisms and have an essential role in the production of growth regulators in addition to improving the physical and mineral properties of the soil, which increases the Impactiveness of bio-fertilizations by adding them with organic Fertilizations and this leads to an increase in yield production 3. The presence of organic and Bio-fertilizations and the addition of organic matter in the soil increases the activity of microorganisms on the earth. Bacteria that stimulate plant growth (PGPR) are essential for many agricultural Yields 20 as different types of (PGPR) eliminate many plant diseases. It facilitates plant growth directly or indirectly, as well as the decomposition of organic matter 16.
Pseudomonas bacteria secrete plant hormones that encourage plant growth, such as auxins, including IAA (Indol acetic acid) and cytokinin. They also secrete the Enzyme (ACC-deaminase) that inhibits the presence of ethylene 5. Trichoderma harzanium fungus is a valuable living throw fungus that is used in biocontrol on a large scale. Experiments in many countries have also shown that Trichoderma mushrooms have a substantial impact in the agricultural field, especially increasing the readiness of nutrients such as nitrogen, phosphorus and potassium through its excretion of some enzymes and its high ability to degrade existing organic substances or soil additives, as well as its high ability to give the plant breadwinner resistance against pathogens 13,18,5 found that the addition of mushrooms Trichoderma spp. It gave the highest level of nitrogen and phosphorus at each level of organic matter, and the addition of mushrooms gave the highest values to the weights of dry matter of the tomato plant.
Showed 22 when adding organic matter (sheep, poultry and horse manures) in interaction with bio-fertilization (Azotobactre chroococcum, Pseudomonas florecienis (that the organic matter contributed either alone or in interaction with growth-stimulating bacteria in increasing the growth and production of potato plants.
The macronutrients in general and the macronutrients in particular are among the factors that affect the yield of the plant due to their importance in the formation of the vegetative, root and yield Among the most important of these macronutrients are N, P, K These nutrients come from mineral Fertilizations that are added to the soil 11,12 found in their study conducted to find out the impact of the interaction between organic and mineral fertilization and for two seasons on the growth and yield of potatoes when adding urea fertilization at four levels (0, 50%, 75%, 100%) of the Fertilization recommendation approved in his study 24 Results of the spring season showed that the 100% treatment outperformed the concentration of nitrogen and potassium in the leaves as it reached 2.07% and 3.65% respectively, compared to the comparison treatment which gave the lowest rates for the aforementioned traits 25 found in his study, which was conducted to find out the impact of the level of mineral and organic Fertilizations added to the soil on the characteristics of the Mineral content, to the presence of superiority in the aspects of the study when adding nitrogen Fertilization with an amount of 240 kg N H-1, compared to the comparison treatment, which gave the content of leaves at the maturity stage of Nitrogen, Phosphorous and Potassium were 4.77, 0.45 and 4.67%, respectively, compared to the comparison treatment, which gave the lowest average for the aforementioned traits.
The study aimed to know the impact of organic, Bio and Mineral Fertilizations, with the interaction between them on characteristics of Mineral content of the shoots and tubers of potato plants
MATERIALS AND METHODS
The study was carried out during the 2021 spring planting season at the Fallujah palm station belonging to the Department of Horticulture, the Ministry of Agriculture, on gypsum soil to study the impact of organic matter and bio-fertilization with P.Seudomonas florecienis bacteria, Trichoderma harzanium and mineral Fertilization on vegetative growth characteristics, Mineral content and yield traits. RCBD randomized complete blocks with three replications. The area required to carry out the experiment was determined, and the process of preparing the soil for cultivation was carried out by performing orthogonal plowing, smoothing and leveling operations. Soil samples were taken from a depth of 0.3-0 m from different sites of the field. They were mixed well, dried aerobically, smoothed and passed through a sieve with holes 2 mm in diameter, from which samples were taken to conduct some physical and mineral analyses and the results of which are presented in table (1). A field was divided into three sectors, and each sector was divided into 15 experimental units, and each experimental unit was into three lines (each 2.50 m long and the distance between line and the other 0.75 m) left a distance of (1 m) between the experimental units and (2 m ) between the sectors.

The Bacterial inoculum was multiplied by taking a weight of 15 g of the nutritional medium (Nutrient Broth) dissolved in a liter of distilled water. The pH of the solution was adjusted to 7.5 -7, then sterilized by the autoclave, the solution was cooled, and the liquid culture was prepared by taking a smear of Pseudomonas bacteria by means of a loop, the lube was inserted into the container flask. The nutrient solution must be carefully designed to prevent other organisms from entering the food environment and contaminating it. This process was carried out inside a Hood device sterilized by alcohol; after the culture process was carried out, the bacterial culture was placed in the incubator at a temperature of 28 °C for Pseudomonas bacteria for 72 hours until signs of growth appeared if Discoloration and turbidity appeared in the solution. The density of Pseudomonas inoculum was 2.3×108 CFU.
After preparing the bacterial inoculum from Pseudomonas bacteria, the bacterial inoculum was added. The tubers were contaminated with the liquid nutritional medium prepared in advance in the laboratory by adding 10% gum arabic and immersing the tubers in the nutrient medium for half an hour to ensure cell adhesion to the tubers. After placing the vaccine, the tubers were directly covered with soil to avoid the impact of sunlight and drought on the vaccine; the Agricultural Research Department prepared local isolates of the bio-vaccine. Ministry of Science and Technology 15.
Sheep residues were added to the soil after they were obtained from the place near the implementation site. The search was done in a pit of dimensions (2 x 3 x 0.5) m.

DISCUSSION
The main reason for the increase in the characteristics mentioned in tables ( 2, 3, 4, 5, 6, 7, 8 and 9) may be due to the components of the added organic fertilization containing many nutrients, in addition to the fact that its components are decomposed and thus stimulates the growth of the plant by providing macro and micronutrients Which the plant needs to increase the Mineral content of the potato plant. Organic fertilization improves the physical properties of the soil, as it helps the roots to spread and increase of absorption of elements and water. These two factors contribute to forming a good root system reflected in the nutrient content of the plant and tubers 17.
The reason for the increase in the concentration of nutrients N, P and K in the soil may be due to bio-fertilization contains nitrogen-fixing organisms and phosphate-dissolving organisms,
Table 8. Impact of organic, bio-fertilization and mineral fertilizations on the starch content of tubers (%)
The role of these organisms in the secretion of organic acids, growth regulators and chelators leads to an increase in the concentration of remaining nutrients in the soil. It may be due to the rise in the surface area of the roots, which increases the absorption capacity of the roots and, thus, the concentration of the remaining elements in the soil. The rest of the nutrients with bio-fertilization was more apparent when added with mineral fertilization because of what the latter provides of ready-made nutrients and easy to lose by volatilization, washing, sedimentation and fixation in the soil. Also, the integrated fertilization between the three vital, mineral and organic Fertilizations has an essential role in increasing the concentration of nutrients remaining in the soil 10,8. The impact of bio-fertilization on the absorbed nitrogen, phosphorous and potassium came from the critical role of bio-fertilization in improving some of the soil's physical, mineral and fertility properties and then improving the absorption of those elements. Nutrients by plants, as the response to bio-fertilization, were clearer when added with Mineral fertilization because of what mineral fertilization provides from nutrients ready for absorption 21.
The increase in the concentration of nutrients in part before the plant may be attributed to converting the unready formula to its ready-to-absorb formula, which is in line with what was mentioned by 9.
That bio-fertilizations are essential in increasing the average concentration of nutrients nitrogen, phosphorous and potassium in plants. The superiority is due to the availability of nutrients in a balanced and integrated manner as a result of adding mineral, organic and biological Fertilizations together. Thus bio-fertilization is distinguished by providing growth stimulants and regulators that increase the growth of the root system, as well as the availability of nitrogen in the soil solution and organic fertilization. Provide a balanced growth medium of nutrients, followed by mineral Fertilization, in which the plant is equipped with the necessary elements.
CONCLUSION
All of this contributes to improving the plant's content of nutrients, especially nitrogen, to build a good root and vegetative group that can benefit from the elements available in the soil and a vegetable group that performs its vital activities that help increase the concentration of elements in the tubers, and these results are consistent with 27 who showed that the plant yield is of high value from the plant's nitrogen content when integrated fertilization is available, which helps the plant to grow actively, manufacture nutrients and transfer them to the yield
