The objective is to analyze techniques to form mulberry seedlings with different cutting sizes and forms of fertilization with N-P-K aiming a low production cost and an easy application in field. The experiment was carried out in a screened nursery, with a shading of 34%. The treatments were distributed in randomized blocks (RB) and compared in a 2x4x3 factorial design with five replications and 12 plants per plot. The factorial design consisted of two cutting lengths (10 and 20 cm) distributed in plastic tubes of 70 and 120 mL, four mulberry cultivars (IZ40, IZ10/1, Korin, and IZ3/2), and two types of fertilization: addition of 84 g of Osmocote® for each kilo of substrate, fertigation with aqueous solution containing 84 g of 14-14-14 N-P-K for each kilo of substrate, plus a control treatment (without fertilization). The commercial substrate Basaplant citrus® was used. 90 and 140 days after planting, assessments of percentage of rooting were carried out. At 140 days, shoot length (cm), number of shoots, number of leaves, root length (cm), and shoot and root green and dry matter were evaluated. The data obtained were evaluated using the Sanest software and Tukey test (P<0.05). Cuttings of 20 cm in length in tubes of 120 mL are recommended for the best formation of mulberry seedlings with the application of N-P-K fertilizer through fertigation. The cultivars showed different rooting potentials and shoot development. The best results are for Korin and IZ 10/1.
