The socioeconomic situation aggravated by the COVID-19 post-pandemic, and international conflicts, has caused instability in the availability of fertilizers. In order to propose alternatives to mitigate these deficiencies in the availability of fertilizers, the use of an effluent produced in the refining of edible oils, with fertilizing properties, complemented with a natural seaweed fertilizer, is proposed to improve the nitrogen deficiency of the first liquid fertilizer, resulting in a biol with nutrients assimilated by the crop. Experimental work was carried out at Fundo la Querencia, located in the Province of Huaura, Lima, Peru. The identification of the optimum dose of the liquid fertilizer was the objective of the present research, the obtained biol was applied to the radish crop, the dose used by farmers near the La Querencia farm and from experiences found was considered, which is 3 L of biol/200 L of water, as well as the resulting concentration of macronutrients and micronutrients when completing the industrial effluent with marine algae. The experimentation was carried out in the field of the selected crop, where a Completely Randomized Block Design was applied, with five treatments: T1, T2, T3, T4 and T5 with fertilizer doses 0, 2, 3, 3, 4, 5 L/200 L, respectively. The analysis of variance determined that the T5 treatment obtained a higher yield of 47.83 tn/ha, and also stood out in weight and length of the plant, polar and equatorial diameter of the plant, with respect to the other treatments tested.
