Trial to Improve the Amount of Biomass in Hydroponic Barley

Forage seed germination results in young tender grass production equivalent to that of spring, and thanks to their efficiency it is considered today as an alternative solution compared to other high fodder prices, and with their ease of production in a cycle not exceeding 8 days. the reuse of biologically treated wastewater in agriculture can have positive impacts on the development of the plant, to study the effect of this reuse on the improvement of the quantity of biomass in hydroponic barley, three trials were carried out, test T (irrigated with distilled water), test P (irrigated with well water), test E (irrigated with treated waste water). Indeed, the results obtained indicate that the treated wastewater has a considerable effect on increasing the amount of biomass, thus, this technique relies on the absorption of the nutrients found in the treated wastewater by the plant and allows to transform them, which increases their mass, and improves certain physiological characteristics (roots and shoots).
