Study on the nitrogen nutrition and the yield response from nitrogen fertilizer application to hybrid rice. I. The fate of urea nitrogen applied to soil and its effect on N supply



Journal of Nanjing Agricultural University 2: 69-75



In a microplot experiment 15N-labelled urea was applied at various growth stages of hybrid rice. Application date affected N recovery by the plant, N retention in the soil, N deficit, the ratio of urea-N distributed to the grain to total urea-N uptake by the shoot and recovery of residual urea-N by a subsequent wheat crop.
