Abstract
A pot experiment was carried out at the Experimental Farm of Environ. & Bio-Agriculture Dept, Fac. Agric., Al-Azhar Univ., Nasr City, Cairo, Egypt, during the summer season of 2022 to study the impact of some Plants biostimulants (PGPR, AMF, Chlorella extract, EM, and vermi tea) on growth, chemical composition and yield in Ipomoea batatas L plants. Sweet potato grown organically. Results could be summarized as follows: All treatments using biostimulants increased all vegetative growth parameters of sweet potato plant. As for chlorophyll A, B and total chlorophyll, the use of biostimulants, especially vermi tea (Treatment No. 7), had positive results. As for the chemical properties, treatment 9 (compost with mycorrhiza inoculation, PGPR and chlorella extract gave the best value for carotenoids), and both treatment 7 (compost & vermi tea) and treatment 10 (compost with mycorrhizal inoculation, PGPR, chlorella extract and vermi tea) gave the best value. Ascorbic acid value. As for fats, there were no differences between the control (the recommended dose of chemical fertilizer) and between treatments 5 (compost + chlorella extract), treatment 8 (compost, mycorrhiza, PGPR and vermi-tea). Regarding protein, treatments 3 (compost with inoculation with mycorrhiza) and treatment 4 (compost with PGPR) were the best, and treatment 3 was better for fiber. Regarding sugars, treatments 3, 4, 7 and 8 were the best, and treatment 10 was superior to all treatments in the percentage of starch. As for moisture, the highest moisture content was using treatment 2 (compost alone), and treatment 10 and it outperformed all treatments.
