<![CDATA[Katuk (Sauropus androgynus L.) is one of the indigenous vegetables in Indonesia which has the potential to be developed as an alternative vegetable to meet nutritional needs. The development of katuk plants so far is usually carried out in shade intensity with various levels and types of fertilizers. This study aimed to determine the effect of shade intensity and appropriate level of fertilizer to increase growth and yield of katuk production. The experiment was carried out using a completely randomized block design (RCBD) with split plot factors with the main plot being shaded and sub-plots being the level of fertilization. Shade intensity consisted of 4 levels, namely N0 (without shade), N1 (55%), N2 (65%), and N3 (75% shade). The fertilizer consisted of 4 levels of NPK 15-15-15, namely P1 (50 kg ha-1), P2 (100 kg NPK ha-1), P3 (150 kg NPK ha-1), and P4 (200 kg NPK ha-1). The study was conducted with 3 replications so that 16 combinations were obtained, with 48 experimental units. The results showed that there was no interaction between shade and fertilizer level. Single treatment of fertilizer level did not give a significant effect on all parameter of observation. Shade treatment on katuk plants for the purpose of commercial leaf vegetable production should be carried out with 65% shade.
