Question

Q4. Give reasons
a) Sowing of seeds should be done at appropriate level in the ground

b) Manure is considered better than fertilizers yet fertilizers are used more than manure

c) Paddy cannot be grown in winter season

​

Answer 1

Explanation:

1. Sowing seeds at proper level is important because if sowed on the field then it will be eaten by birds if sown at too much deepth then the shoot will not be able to come out.

2. Manure is considered better than fertilizers because if manure is added more it will not harm the plants but if fertilizers are added more then they will harm the plants yet fertilizers are used because manure does not have nutrients like potassium phosphorus and nitrogen so to fulfil the need of these nutrients fertilizer is required.

3. Paddy cannot be grown in winter because it is a summer crop and it requires a lot of water.
