Need for Suitable Genotypes<br />
for Different Regions<br />
S o r g h u m is g r o w n in areas w h e r e t h e rainfall is<br />
restricted to 4 m o n t h s in a year, i.e., J u n e to<br />
September. It is only in s o m e parts of Maharashtra.<br />
Andhra Pradesh, a n d Karnataka that s o m e<br />
rainfall occurs in O c t o b e r also. O n e of t h e m o s t<br />
critical factors in t h e g r o w i n g of s o r g h u m is that of<br />

t h e r e has b e e n a w o r l d w i d e d e m a n d for coarse<br />
grains as f e e d for animals, t h e r e w o u l d be s c o p e<br />
for exporting t h e surplus production of t h e s e<br />
grains.<br />
There is n e e d for convincing data to s h o w h o w<br />
a n d w h y it is advantageous to increase t h e<br />
production of millets a n d also to procure and stock<br />
t h e s a m e in large quantities. Research should be<br />
intensified in this regard a n d data m a d e available<br />
t o policy m a k e r s t o enable t h e m t o take proper<br />
decisions and i m p l e m e n t t h e m .<br />
Earlier s o w i n g s are<br />
preferred to avoid shoot fly d a m a g e a n d t h e risk of<br />
drought during t h e maturity period. Varieties<br />
g r o w n in different areas vary very m u c h in<br />
duration. Traditional varieties are s u c h that t h e y<br />
usually m a t u r e after t h e cessation of rains.<br />
A t t e m p t s are n o w being m a d e t o introduce<br />
hybrids or high-yielding varieties of shorter duration<br />
that are suitable for varying rainfall situations.<br />
Introduction of hybrids and varieties w h i c h m a t u r e<br />
earlier than t h e traditional varieties has brought in<br />
t h e p r o b l e m s of earhead p e s t s a n d diseases since<br />
t h e grain f o r m a t i o n and maturity take place w h e n<br />
h u m i d i t y is high and t h e rains are e x p e c t e d . The<br />
p r o b l e m o f drying t h e grain has also c o m e t o t h e<br />
fore because of cloudy w e a t h e r at that t i m e . It is<br />
for t h e s e reasons that t h e p r o d u c e is brought to<br />
t h e market w h e n still w e t . Therefore, distress<br />
sales are reported to take place in s o m e markets.<br />
Public sector organizations also avoid p r o c u r e -<br />
m e n t t o escape f r o m t h e p r o b l e m s o f storage.<br />
It w o u l d be advantageous in m a n y w a y s to<br />
develop and r e c o m m e n d hybrids or high-yielding<br />
varieties w h i c h fit into t h e rainfall r h y t h m of a<br />
place rather than to introduce only early m a t u r i n g<br />
t y p e s irrespective of t h e duration of rainfall.<br />
Gardner (1972) has stated that " M a x i m u m grain<br />
production can be attained by breeding for a m o r e<br />
limited set of e n v i r o n m e n t s rather than breeding<br />
for very broad adaptability. This also has t h e<br />
advantage of protection against disasters d u e to<br />
diseases or insects w h i c h o f t e n attack a specific<br />
g e n o t y p e . " It has been universally realized that<br />
m a x i m u m e c o n o m i c yields can be e x p e c t e d only<br />
w h e n t h e g r o w t h pattern of the crop is w e l l<br />
adapted to environmental conditions.<br />
Research approaches need to be clearly d e f i n e d<br />
w i t h regard to breeding of varieties for different<br />
agro-climatic regions. If short-duration varieties<br />
are introduced, measures will also have to be<br />
s u g g e s t e d t o tackle t h e p r o b l e m s that g o w i t h<br />
t h e m . A proper approach should be f o r m u l a t e d<br />
a n d i m p l e m e n t e d at research as w e l l as at<br />
d e v e l o p m e n t levels in this regard.<br />
Need for increased Attention<br />
to Rabi Jowar<br />
In Andhra Pradesh, Maharashtra, and Karnataka,<br />
rabi jowar is valued m o s t . The prices of rabi jowar<br />
are usually higher than t h o s e for other kinds. The<br />
p r o b l e m s of raising rabi jowar are on t h e increase<br />
because of considerable soil erosion taking place.<br />
The soils are g e t t i n g less and less retentive<br />
because of the w a s h i n g a w a y of t h e t o p soil a n d<br />
t h e y are b e c o m i n g m o r e drought prone. The<br />
p r o b l e m s concerning t h e d e v e l o p m e n t and release<br />
of suitable varieties or hybrids, soil and<br />
w a t e r conservation, soil fertility m a n a g e m e n t ,<br />
etc.. are t h e m o s t important ones. Certain p e s t s<br />
a n d diseases are also a s s u m i n g a serious magnit<br />
u d e . Research p r o g r a m s n e e d to be intensified<br />
