Your answer is partly correct. But, The
correct answer is Timing of water (soil
moisture) availability is most important for high
yields in sorghum.
12
Your answer is correct. Timing of water (soil
moisture) availability is most important for high
yields in sorghum.
13
Your are right. The most critical stage for
moisture stress is boot stage of sorghum crop.
14
Your answer is not correct. The correct answer
is The most critical stage for moisture stress
is boot stage in sorghum plant growth.
15
Your are right. The water absorbed by sorghum
during the first month after sowing is relatively
small.
16
Your answer is not correct. The correct
answer is The water absorbed by sorghum during
the first month after sowing is relatively small.
17
If you are not sure, here is the answer. The
correct answer is Yes. The water absorbed by
sorghum during the first month after sowing is
relatively small.
18
Your are right. Continuous rains during grain
filling and grain hardening stage results in
grain mold.
19
Your answer is not correct. The correct answer
is Continuous rains during grain filling and
grain hardening stage results in grain mold.
20
Your are right. Spraying 2 Urea solution at
the time of moisture stress helps sorghum plants
to cope with the moisture stress.
21
Your answer is not correct. The correct answer
is Spraying 2 Urea solution at the time of
moisture stress helps sorghum plants to cope with
the moisture stress.
22
Your are right. Pre-planting irrigation helps
to get higher seedling vigor and early plant
growth.
23
You are partly correct. But, The correct
answer is Pre-planting irrigation helps to get
higher seedling vigor and early plant growth.
24
If you are not sure, here is the
answer. Drooping and withering leaves indicate
the need for irrigating sorghum crop.
25
You are right Presence of waxy bloom on
leaves helps sorghum plants to withstand drought.
26
Your answer is not correct. Brace roots are
for better anchorage of sorghum plants. Ratooning
capacity of sorghum can be taken advantage if the
main crop fails due to drought. The correct
answer is Presence of waxy bloom on leaves
helps sorghum plants to withstand drought.
27
If you are not sure, here is the
answer. Presence of waxy bloom on leaves helps
sorghum plants to withstand drought.
28
You are right Drooping and withering leaves
indicate the need for irrigating sorghum crop.
29
Your answer is not correct. The correct answer
is Drooping and withering leaves indicate the
need for irrigating sorghum crop.
