The intercropping of vegetables is quite common practice among farmers. In this work, kale and cariru intercropping, under two fertilization alternatives in side dressing, as an additive to residual soil fertility in protected cultivation was studied . The trial (30/07/2014 to 17/09/2014) had an experimental design in randomized blocks with three repetitions (2.26 m2) and nine treatments (three systems of cultivation: single kale, single cariru and consortium of kale + cariru; and three managements: test – only water; biofertilizer- 15%, in water; and urea - 1 g L-1 of water).Managements were applied weekly (10 L per plot). The agronomic indexes (fresh mass, kale leaf number and cariru branch number) stood out in single systems, with the performance, excepting kale leaf number, standing out with the use of urea. However, the results of Productive Efficiency, the Efficient Use of Land and Gross Income, keeping consistent with each other, attributed to intercropping better overall utilization of the factors, particularly, with the use of urea.
