This research was conducted at CIIEY-UNAP km 17 to determine the productivity of Cuba OM-22 pasture fertilized with two organic fertilizers. The treatments evaluated were (T1 without fertilizer; T2 cow manure 2 kg/m2; T3 chicken manure 2 kg/m2; T4 cow manure 4 kg/m2; and T5 chicken manure 4 kg/m2), with 4 replicates each. The design used was Completely Randomized Blocks (CRB). The results showed that chicken manure was the most effective fertilizer. T5 reached the highest pasture height (2.30 m), significantly surpassing T1 (1.29 m) and all treatments with cow manure. Regarding biomass production, T5 obtained the highest values in green matter (102.35 Tn/ha) and dry matter (26.17 Tn/ha), with statistically significant differences compared to the other treatments. Regarding nutrient content, T5 had the highest values for phosphorus (0.42%) and crude protein (8.83%). Potassium content was ...
