Experiments on the plantation of tropical green manuring plants and pastures on three red soils of western Kwangtung Province during 1963-1964 give the following remarks:Tephrosia candida and Crotarlaria anagyroides could be planted in poor soils under a rather dry soil condition.Tithonia diversifolia gave high yield within a short growing period but successwe plantation of this plant was confined only to the fertile soils.Tephrosia vestita has been found very resistant against dry and infertile soil condition.It was the only plant which should grow on acid sandy soil of the hill land.Under good soil moisture condition Sesbania cannabina could stand on infertile soils with rapid growth.Pueraria phaseoloides and Calapogonium mucunoides showed wide adoptability in this region.They served as good cover plants under bad soil conditions.Pueraria phaseoloides,Centrosema pubescens,Desmodium ovalifolium,Mimosa invisavar inermis and Oldenlandia auriculavia grew better under a shady condition than any other plants introduced in the experiments.
