Effect of Local Lypreparedorganic Fertilizers by Support with Phosphate Rock and Decomposed Biology in the Production of Seedlings and the Yield of the Lettuce Plant

Abstract

The experiment included recycling solid organic waste and improving its components to produce organic fertilizers. In two stages: The first: achieved by preparing a mixture of organic wastes at a ratio of C: N 30: 1. Anaerobically I fermented for 60 days after inoculating 5% of the active soil pollen. Second: The fermentation products 0, 10% and 20% of the raw Phosphate Rock (RP) were prepared, and then the treatments were aerobically fermented for 30 days with inoculation from 3% active soil. The products of the second fermentation stage were used with a treatment of commercial peatmoss and a control treatment using agricultural soil in testing the germination and production of seedlings of the lettuce plant of a local variety, and the most important results were: The superiority of my meaning in the germination percentage ranged between 93.2 and 96.5% for the treatments that made organic fertilizers prepared locally with investigation The highest rate ranged between 9.8 and 10.6 cm for the height of the seedlings during a period of 10 days, depending on the results of the test of germination and production of seedlings, the use of the same treatments was tested at a rate of 3% with agricultural soil in the anvil experiment, with the use of the first control treatments using fertilizer with a commercial seasonal addition of 3% and control Again, using the fertilizer recommendation from mineral fertilizers for the lettuce plant, as seedlings that were produced in the first test experiment were used, and the most important results were: All the treatments prepared from fermentation of residues and equipped with phosphate rock outperformed the two treatments of peat moss and the recommendation of mineral fertilizers to achieve the best results in the morphological characteristics of plant height, number of total and edible leaves, and the average weight of the soft head, which ranged between 960.4 and 990.7 g. Significant superiority of all rates of locally prepared organic fertilizer treatments over fertilizer recommendation treatment, with chlorophyll values, lipid content, nitrogen and phosphorus concentration, and leaf content of Fe, Zn, Mn and Cu. With a significant effect of the treatments from prepared fertilizers and commercial peatmoss in increasing the content of Nitrogen fixing bacteria and Phosphate solvent and the concentration of Nitrogen and ready Phosphorous compared to what was found in soil treatment.
