R s / h a . Considering t h e additional cost of production<br />
of HYV s o r g h u m , this relatively small differe<br />
n c e in total value of HYV s o r g h u m m a y explain<br />
t h e limited adoption of high-yielding varieties in<br />
m a n y parts of India.<br />
In v i e w of t h e general importance of s o r g h u m<br />
as a major source of grain and as fodder for cattle,<br />
t h e value of fodder should be considered in<br />
breeding n e w varieties.<br />
If a hybrid s o r g h u m w i t h high quality s t r a w<br />
c o u l d be d e v e l o p e d w i t h o u t a serious decrease in<br />
grain yields, the resulting attractiveness to t h e<br />
farmer w o u l d probably greatly speed adoption of<br />
such a type.<br />
Conclusion<br />
India is a major s o r g h u m producer in t h e w o r l d ,<br />
although its yields are only about half that of t h e<br />
w o r l d average. Yield increases through n e w<br />
varieties are possible; h o w e v e r , t h e adoption of<br />
n e w varieties m a y be constrained because of t h e<br />
