What is NOT a prerequisite for sowing?
a) Good tilth
b) Optimal soil moisture at sowing depth
c) High soil temperature
d) Manures and fertilizers
Answer: c) High soil temperature
Explanation: High soil temperature is not necessarily a prerequisite for sowing, as it can vary by crop and location. The essential requirements are good tilth, proper soil moisture, and the use of manures and fertilizers.
Which of the following is NOT a form of vegetative propagation used for sowing?
a) Seeds
b) Stem cuttings
c) Rooted slips
d) Tubers
Answer: a) Seeds
Explanation: Vegetative propagation involves methods like stem cuttings, rooted slips, and tubers, while seeds are used for regular sowing but do not qualify as a form of vegetative propagation.

a) Red rot in sugarcane
b) Tikka leaf spot in groundnut
c) Both a and b
d) Neither a nor b
Answer: c) Both a and b
Explanation: Seed materials should be free from pests and diseases like red rot in sugarcane and tikka leaf spot in groundnut to promote healthy crop growth.
Which characteristic is NOT required for seed material used for sowing?
a) Free from dormancy
b) High percentage of germination
c) High percentage of inert material
d) Viable
Answer: c) High percentage of inert material
Explanation: Seeds should be viable and free from dormancy and inert material to ensure good germination rates.
What type of propagation is used for sowing potatoes?
a) Stem cuttings
b) Tubers
c) Rooted slips
d) Rhizomes
Answer: b) Tubers
Explanation: Potatoes are propagated using tubers, which are storage organs that can sprout new plants.
Which factor indicates that a seed is likely to germinate successfully?
a) High purity
b) Free from dormancy
c) High viability
d) All of the above
Answer: d) All of the above
Explanation: A seed that is high in purity, free from dormancy, and highly viable is likely to germinate well.
Which type of crop would most likely require stem cuttings for sowing?
a) Sugarcane

Why is soil moisture at sowing depth a critical prerequisite for successful sowing?
a) It supports seed germination and root growth.
b) It prevents soil erosion.
c) It helps control weed growth.
d) It maintains optimal soil temperature.
Answer: a) It supports seed germination and root growth.

What issue can arise if seeds exhibit dormancy?
a) Seeds may not germinate when sown.
b) Seeds may germinate too quickly.
c) Seeds may contain pests.
d) Seeds may have low viability.
Answer: a) Seeds may not germinate when sown.
Explanation: Dormant seeds may not germinate immediately, leading to delays in crop establishment.

a) 60-70%
b) 80-90%
c) 98-99%
d) 100%
