  • Stylosanthes（ Stylosanthes guianensias SW） is a leguminous crop used as green manure and forage in the tropics. Nitrogen content is one of the important index affecting the green manure quality for the leguminous green manure. The nitrogen contents of 134 accessions of Stylosanthes green manure germplasm were analyzed and evaluated. The result indicated that 35 accessions of the germplasm contained more than 2% of nitrogen,accounting for 26.1% of the total accessions of the germplasm; 98 germplasm accessions contained 1. 5%-2.0%of nitrogen,73.1% of the total germplasm accessions. All these accessions were grouped into class II. Only one germplasm accession contained nitrogen below 1. 5% and were grouped into class III.

Abstract: Stylosanthes（ Stylosanthes guianensias SW） is a leguminous crop used as green manure and forage in the tropics. Nitrogen content is one of the important index affecting the green manure quality for the leguminous green manure. The nitrogen contents of 134 accessions of Stylosanthes green manure germplasm were analyzed and evaluated. The result indicated that 35 accessions of the germplasm contained more than 2% of nitrogen,accounting for 26.1% of the total accessions of the germplasm; 98 germplasm accessions contained 1. 5%-2.0%of nitrogen,73.1% of the total germplasm accessions. All these accessions were grouped into class II. Only one germplasm accession contained nitrogen below 1. 5% and were grouped into class III.
