Production
of Maize
On the other
hand, maize varieties like GS-2 and GM-3 gave different
results under this simulation. Maize GM-3 was found more vulnerable to
elevated
temperature (3-4 degree Celsius as compared to GS-2.
Both the cultivators responded well at elevated temperature of two
degree
Celsius. The GS-2 variety of maize production per hectare was 4,200 kg
under
the elevated maximum temperature of one degree Celsius against the
normal yield
of 4,000 kg per hectare. However, it increased to almost 4,800 kg per
hectare
under two degree Celsius temperature. The yield fell to 3,900 kg per
hectare
under five degree Celsius temperature.
Similarly, in GM-3 variety the yield was 3,700 kg per hectare under the
elevated maximum temperature of one degree Celsius which increased to
3,850 kg
per hectare under two degree Celsius temperatures. The normal yield was
3,550
kg per hectare. The yield went down to normal (3,550 kg per hectare) at
four
degree Celsius. The report says that gradual temperature reduction
poses a
negative impact on maize yield. [1]
