Complete answer: Rice is a tropical plant that requires adequate water to develop well. Along these lines, the soil utilized in developing rice ought to have a decent water-holding limit.

-Paddy is filled in the nursery and afterward relocated to the primary field for four fundamental reasons.

-Since it is anything but difficult to flood a little territory, seeds can be planted much before the storm, and consequently, the primary rainstorm can be utilized for watering the relocated harvest in fields.
-Principle field is puddled not long prior to relocating. In this way, all the weeds in the field are taken out. At the point when paddy plants are relocated, the weeds don't contend as they need to restart from ZERO and the paddy as of now has a lead in the race. Water is filled after transplantation and accordingly, in most pieces of the field, weeds don't sprout.
-Paddy plants shoot out as a solitary branch. When upset either by squashing them or by relocating them, they shoot out different branches, and subsequently the development is normally expanded. This is the main explanation for relocating.
