The effect of using chicken manure compost (CGP) at levels of (T1) 0, (T2) 10 and (T3) 20 t/ha, on green forage yield (GF), dry matter (DM), plant height (PH) and total protein (TP) of alfalfa, in a pasture area of Huancayo (Junín, Peru) was evaluated. The fertilization was done on the first day of the study and at the beginning of week 6. The first cut was done at 42 days of the first fertilization and the second at 35 days of the second fertilization. The yields at the second cut of GF in T1, T2 and T3 were 18.6, 23.5 and 26.8 t/ha (p<0.05), of DM were 2.5, 7.0 and 7.1 t/ha (p<0.05), of TP were 0.8, 1.0 and 1.2 t/ha (p<0.05) and of PH were 60.8, 66.9 and 63.8 cm, respectively (p<0.05). It was shown that it is possible to use broiler chicken manure compost to obtain an improved organic alfalfa production.
