Abstract
This paper details an experiment which was carried out from October 1997 to April 1998 at the Wuqiao experiment fields of the China Agricultural University in Hebei Province. The aim of the experiment was to study the effects of nitrogen, phosphate, and potassium fertilizer practices on the quality of forage Secale cereale. Mathematical models were established for the quality of rye hay based on the N, P and K fertilizer treatments. The dynamic relationship between experimental factors and the quality of Secale cereale have been diagrammatically represented with graphs in this paper. The results showed that one of the most significant factors that influenced the hay quality of forage Secale cereale was the N fertilizer practice. The CP, NDF and ADF contents of forage varied significantly with different treatments. With increasing N application rates, forage CP tended to increase, whereas NDF and ADF declined. With increasing applications of P and K, forage NDF and ADF tended to increase. In conclusion, it is believed that to improve the hay quality of forage Secale cereale it is necessary to apply relatively higher N fertilizer rates and relatively lower P and K fertilizer rates.
