The Nitrate Accumulation in Sorghum Sudangrass Hybrids Varying with the Level of Nitrogen Fertilizer
Publication Date
1997
Description
A field experiment with 80, 160 and 240 kg N/ha application levels was carried out to study the nitrate nitrogen accumulation in the sorghum sudangrass hybrids at Iri National College of Agriculture and Technology farm in 1995. The nitrate nitrogen content of Xtragraze II exceeded the safe level of ruminants at the level of 160kg application, and decreased at the low level in the later stage of growth, but that in Civa 1990 was almost kept constant at the same level. Nitrate nitrogen accumulation of Civa 1990 was higher than that of Xtragraze II. A sum exceeding 160kg N does not necessarily result in increasing nitrate nitrogen in the sorghum sudangrass hybrids. It is suggested that 160kg application may result in toxic levels of nitrate nitrogen in the early stage of growth, and special attention must be given in feeding them.
