The study aimed to identify hydroponics and its role in improving the self-sufficiency rate, and the results showed that hydroponics is one of the most important scientific means for research in plant nutrition in a way that makes its roots immersed in the nutrient solution and fixed by supports controlling the aeration of the solution, by providing the oxygen necessary for the roots to breathe.

We can control all the nutrients and light, the appropriate temperature, and the nutrient solution is similar to fertile soil.

This method allows us to know the mineral elements that the plant needs in the natural environment and that are necessary for its growth.

Hydroponics has several advantages compared to traditional farming, which is represented in the absence of agricultural techniques, fertilization, and the cleanliness of agriculture, i.e.

the absence of weeds, and thus avoiding the work of cutting weeds and only cleansing the ponds, including the ease of replanting and the lack of labor.

It is also possible to know the amount of mineral substances consumed by the plant, as we get An early agricultural product, and the study recommended the preparation of detailed technical and economic studies at the national level for aquaculture projects, to examine the possibilities of applying this technology at the national level, so that these studies depend in their data on the results of the actual application of these systems on a larger scale through farms and agricultural research stations.

Affiliated to the faculties of agriculture and agricultural research centers, and preparing economic studies to study the returns achieved from the expansion of aquaculture, represented in the expected savings in agricultural economic production resources such as land and water, as well as other production requirements, the most important of which are fertilizers, in addition to studying the risks and costs of applying this technology and comparing it.

the aforementioned returns
