to good quality seeds by farmers. It was assumed in this study that use of low quality seed was among the factors that could be significantly affecting the low production of sorghum in the district. This study focused on the physiological quality of seed which refers to the germination capacity, viability, characteristics related to dormancy and. Andropogon virginicus is available for commercial purposes (through the horticultural trade) in the USA and within the EPPO region (EPPO, ). However, there is no evidence that the species is commonly imported as seed into the EPPO region for horticultural purposes.   Samuel C. K. and Chatterji S.

In the USA, A. virginicus mainly has an eastern and central native range. The species is also present in California where it is regarded as non-native. It is reported as invasive in Hawaii, where it was first reported in This species has been introduced and.

Koernicke () presented the first attempted classification of the cultivated forms of the whole world. He recognizes them as com- prising a single species Andropogon sorghum (L.)

Texas and New Mexico produce 75 to 80 per cent of the Sudan grass seed (Andropogon sorghum[Sorghum bicolor] var. Sudanensis) of the United States. New varieties will make it possible to obtain 4 to 6 months of grazing in most parts of Texas and the Southwest, with gains ranging from 1 to 2 lb. per day per animal, and a carrying capacity of one cow per acre under favourable conditions. The author would like to express his appreciation of the help and advice he has received on these statistical matters from Dr. K. Mather, of the Galton Laboratory, University College. The author wishes to thank Prof. E. J. Salisbury, under whose direction this work has been done, and Prof. T. G. Hill, for helpful criticism and advice during the course of this investigation.   SOLOMON, S.: Studies in the physiology of phanerogamic parasitism with special reference to Striga lutea Lour. and S. densijlora Benth. on Andropogon sorghum Hack. 1.
