Abstract
A field experiment was carried out to study the effect of nitrogen application on grain yield and leaf nitrogen content of three varieties of sorghum. The Cate and Nelson's [1971] method was used to predict the nitrogen critical level. Nitrogen application significantly increased grain yield and leaf nitrogen content. Grain protein content increased with nitrogen application. Nitrate-nitrogen and total nitrogen are suitable for determining nitrogen status of the plant. Based on the method of Cate and Nelson [1971], the nitrate-nitrogen critical level at 5 days and 30 days after the second N application was 199.0, 99.5 and 87.0 ppm [UPCA S1]; 219.0, 152.0 and 102.0,ppm [6 C]; and 169.0, 369.0 and 87.0 ppm [Dars]. The critical levels for total nitrogen were 0.40, 0.57 and 0.64 percent [UPCA s1]; 0.29, 0.69 and 0.69 percent [6 C], and 0.45, 0.69 and 0.55 percent [Dars]
