Asparagus is one of the main peruvian export products. For a correct fertilization it is important to know the manifestation of the plant in the absence of a certain nutrient. A trial was carried out under controlled conditions in the facilities of the Soil Fertility Laboratory and Greenhouse (LIFS) of the Faculty of Agronomy of the La Molina National Agrarian University. This consisted of a CRD with factorial arrangement and a control, each with three repetitions. The factors studied were nutritional deficiency (Without deficiency and deficiencies of N, P, K, Ca and Mg); and the dose of nutrient solution (50%, 100% and 150%). Plant height, percentage of leaf and crown dry matter, number of stems and coloration, and concentrations of the elements in leaves and crown were evaluated. An adequate fertilization always showed a good response of all the parameters. Foliage coloration was an indicator of deficiency in all elements, mainly in the form of yellowing. Phosphorus deficiency was the one that most affected asparagus in plant height, percentage of dry matter in the root and fewer stems, and causing the fall of the phylloclades due to descending necrosis. Calcium deficiency affected the youngest tissues and meristematic areas, causing deformation and necrosis of shoots. Magnesium deficiency caused necrosis of the phylloclades and their subsequent fall, leaving the stem bare. The increase in the dose of nutrient solution had a positive impact on the number of stems, root magnesium concentration; and negative in plant height and nitrogen and phosphorus concentration in roots, as well as in calcium concentration under nitrogen and phosphorus deficiency. A synergy between potassium and calcium in foliage was observed
