Abstract: The effect of chicken manure application on the chlorophyll content (SPAD value), hay yield and crude protein content of Lolium multiflorum cv. Tetragold were evaluated through a field trail. The experiment included 3 treatments with different nitrogen levels (0, 130.77 and 261.54 kg N/ha) with 3 replicates. The SPAD value was determined by using a Chlorophyll meter at different growth stages. Hay yield and crude protein content were determined simultaneously. Correlation between SPAD value and the other indexes at different growth stages were also calculated. Chicken manure application significantly improved SPAD value at the booting and flowering stages, hay yield at the flowering and maturing stages and crude protein content at flowering. There were significant positive correlations between SPAD value and hay yield, and crude protein content at all four stages.
