Nitrogen uptake by corn and N recovery in grain in dry farmland


, : Nitrogen uptake by corn and N recovery in grain in dry farmland. Agricultural Sciences in China 2(8): 898-905

The effects of precipitation, maize stover and fertilizer application on N uptake and N fertilizer use efficiency were studied in maize cultivars Yandan 12 (1993-97), Shandannong (1998) and Jindan34 (1999-2000) grown in Shouyang county, Shanxi province, China. The treatments consisted of N fertilizer (urea), maize stover and cattle manure application at various rates before ploughing.
