Description The experiment was conducted with four
cultivars of sorghum viz., M35-1, IS-923 (Glo•sy type)
and IS-4621, CS-3541 (Non-glos•y type) replicat•d fiv•
times in a randamis•d block design to examin• varietal
response to seasonal effect on growth and yield. Th•
crop was raised in summer (January, 1984 to April, 1984)
and winter (September, 1984 to D•cemb•r, 1984). The
differential response of cultivars in both the seasons
was assessed by determining growth parameters in terms
of CGR, RGR, RSGR,SLW, NAR, LAI, HI and yield.
Sorghum cultivars grown in summer season has
produced more number of leaves and reduced the duration
of crop growth period by inducing early earhead
emergence, flowering, shorter grain filling period and
maturity period. And produced less total drymatter, 100grain weight and yield.
In summer more number of grains per earhead
were produced and are small in size and lesser in 100grain weight than in winter.
In winter season more plant
drymatter, CGR, RGR (except M35-1) LAI,
yield were obtained.
heiQht totalNAR, HI and
Difference in ;rain size and yield among the
cultivars was caused by different rates of assimilation,
storage after anthesis in the individual grain.
Different storage rates are the result of differential
supply of the individua l grain with assimilate from the
different assimilate production organs.
All sorghum cultivara pe rformed better in
winter season than in: summer Among the cultivars,
glos sy types viz., IS-923 and M3~-1 produced more yield •
