Question

Saplings of paddy plants are transplanted when young but not of the wheat plants.Why ?​

Answer 1

Answer:

Why are paddy seeds first planted in a nursery?

Paddy is grown in nursery and then transplanted to main field for 4 main reasons.

By growing in nursery, it is obvious that only the germinated seeds are shifted to main field and hence plants per unit area is maximum. This also helps in transplanting healthy plants only (in case the nursery has a surplus of plants)

Since it is easy to irrigate a small area, seeds can be sown much before monsoon and hence the main monsoon can be used for watering the transplanted crop in fields.

Main field is puddled just before transplanting. Thus all the weeds in the field are removed. When paddy plants are transplanted, the weeds do not compete as they have to restart from ZERO and the paddy already has a lead in the race. Water is filled after transplantation and thus in most part of the field, weeds do not germinate.

Paddy plants shoot out as a single branch. Once disturbed either by crushing them or by transplanting them, they shoot out multiple branches and thus the growth is naturally increased. This is the most important reason of transplanting.

why are not all crops transplanted

Transplanting is much desired in in many vegetables and flowering plants where delicate seedlings are maintained and nurtured well on a compact and well prepared patch of land for 1 to 2 months. This saves a lot of labour and resources of the farmer. Seedlings from 10 square meters can be transplanted on to one or more acres.

Transplanting is done on a very very large scale in crop plants like rice for water saving, weed control and for maintaining desirable population density.

All plants may not withstand ‘transplanting shock’ due to up rooting and replanting and the procedure may fail (say in wheat).
