NUTRIBORA compost is prepared with Eichhornia crassipes, cow manure and moriches soil. This compost increases sweet pepper production when the optimum dose of 80 t ha^-1 is used. In this research the combination of NUTRIBORA at its optimum dose combined with a mineral fertilizer was used to determine sweet pepper yield for different treatments of planting distance. Experiments were performed with the sweet pepper variety “Jupiter” in experimental plots where four fertilization treatments were applied (T₁: 80 t ha^-1 NUTRIBORA+ 0.4 t ha^-1 12-24-12 NPK in a ground soil previously sown and fertilized with the compost for one year, T₂: 80 t ha^-1 NUTRIBORA+ 0,4 t ha^-1 12-24- 12 NPK in a soil without previous sowing or fertilization, C₁(control): 0.4 t ha^-1 12-24-12 NPK in a soil without previous sowing or fertilization, C₂ (control): 80 t ha^-1 NUTRIBORA in a soil without previous sowing or fertilization) and two sowing distances between plants (0.20 and 0.40 m). A statistical design of random blocks in a factorial arrangement (4x2) with 6 repetitions was applied for a total of 48 treatments. Soluble and total contents of P in NUTRIBORA were low in relation to the other nutrients whereas the soluble and total K showed the highest concentration. Fe y Mn had the highest concentrations among total and soluble micronutrients. Sweet pepper yield varied significantly between treatments (P<0.05). The highest yield was obtained with the treatment T₁ and the lowest yield with treatment T₄. Fruit yield was significantly higher at the seeding distance of 0.20 m (P<0.05).
