Answer 2

Both assertion and reason is correct.

Explanation:

If the seeds are sown too deep, they will not be able to germinate. And if grown at a shallow depth they will be eaten up by the birds and animals. Keeping an appropriate distance is important to avoid the over crowding so that the seeds get sufficient sunlight, nutrient and water. Hence, seeds should be planted at a depth of two times the width, or diameter, of the seed. And for giving good amount of yield proper sowing of seeds are also required.
