10
Your answer is partly correct. Black soils
are vertisols and also fine textured soils
because of higher clay content in these soils.
The correct answer is Sorghum can be grown
in any fertile and well drained soil.
11
Your answer is correct. Sorghum can be grown
in any fertile and well drained soil.
12
Your are right. Sorghum plants tolerate saline
and alkaline soils and do well in the soil pH
range of 6 to 8.5.
13
Your answer is not correct. The correct answer
is Sorghum plants tolerate saline and alkaline
soils and do well in the soil pH range of 6 to
8.5.
14
If you are not sure, the answer is Sorghum
plants tolerate saline and alkaline soils and do
well in the soil pH range of 6 to 8.5.
15
Your are right. Soils infested earlier with
striga should be avoided for sorghum cultivation.
16
Your answer is not correct. Downy mildew,
virus, and congress weeds are not serious
problems in sorghum soils. The correct answer
is Soils infested earlier with striga should
be avoided for sorghum cultivation.
17
Your are right. Sorghum can withstand drought
but not very cool temperatures.
18
Your answer is not correct. The correct answer
is Sorghum can withstand drought but not very
cool temperatures.
19
If you are not sure, here is the
answer. Sorghum can withstand drought but not
very cool temperatures.
20
Your are right. Poor emergence and seedling
growth may result if planted before soil
temperatures reach 35oC.
21
Your answer is not correct. The correct answer
is It is true that sorghum is sensitive to
soil temperature at germination stage. Poor
emergence and seedling growth may result if
planted before soil temperatures reach 35oC.
22
If you are not sure, here is the answer. It is
true that sorghum is sensitive to soil
temperature at germination stage. Poor emergence
and seedling growth may result if planted before
soil temperatures reach 35oC.
23
Your are right. The ability of sorghum to grow
in drier environments is due to waxy coating on
leaves.
24
Your answer is not correct. The correct answer
is The ability of sorghum to grow in drier
environments is due to waxy coating on leaves.
25
Your are right. The ability of sorghum to grow
in drier environments is also due to many
adventitious roots produced by sorghum plants.
26
Your answer is not correct. Sorghum has no tap
root system. The correct answer is The
ability of sorghum to grow in drier environments
is also due to many adventitious roots produced
by sorghum plants.
27
Your answer is not correct. Brace roots in
sorghum serve only for anchoring the plant.
The correct answer is The ability of
sorghum to grow in drier environments is also
due to many adventitious roots produced by
sorghum plants.
28
If you are not sure, here is the answer. The
ability of sorghum to grow in drier environments
is also due to many adventitious roots produced
by sorghum plants.
