Agriculture — II: Food Crops — Question 13

Transplantation is a method of rice cultivation common in deltaic and flood plain regions. The seedlings are first grown in nurseries and after four to five weeks when saplings attain 25-30 cm of height, they are transplanted into prepared rice fields in groups of four to six at a distance of 30-45 cm. In the beginning, the field is flooded with a 2-3 cm deep water. Subsequently, the depth of water level is increased to 4-6 cm till the crop matures.

Two advantages of transplantation method are-

1. Only the healthy plants are picked for resowing in the field and unhealthy plants are discarded.
2. Weeds are removed while resowing.
