What effect does the different concentrations of date kernel extract have on pepper seed germination?
How do different concentrations affect the growth of a pepper plant?
What effect does the extract have on the chemical properties of the soil?
Can date kernels be used as a greywater filter?
After researching studies,it is clear that the dates nuclei contains vehicles and chemical elements. By sending samples to SQU, it is clear that the dates nuclei powder contains phenolic compounds, iron elements, potassium and phosphorus. To answer the search questions we first broke the nuclei of dates to convert it to a 'powder' , then we converted the powder into powders with different concentrations by adding it in the water in different quantities that gave us the concentrations (0.1), (0.01) and (1) then we rose Bring different types of seeds (pepper, tomatoes, okra). We watered all the seeds with all the concentrations. We found that the focus (0.1) was faster germination, which means that the extract is a stimulating material, after that, we started noting the effect of the concentrations on the different seeds, we found that the concentration '0.1 '' was the best of which was that the seeds grew faster in terms of the number of leaves and length. As for the other concentrations, the seedlings withered in them. We took a sample of the soil used before and after to measure the acidity in the soil. The results showed that the extract affects the properties of the soil. At the end, they conducted an experiment to find out whether the date pits were a filter for gray water or not. Indeed, it turned out that they were a filter because the gray water changed from a turbid color to transparent color. To conclude, date pit extract is considered a stimulating substance for seed germination. It can be also used as a fertilizer and It can be also used as a gray water filter.
