Mechanization in crop establishment

Paddy transplanters

Advantages:

• Less labour intensive operation (Transplanting consumes 33 per cent of total labour required in rice production)
• Helps in line transplanting
• Easy weeding and intercultural operations

Self-propelled paddy transplanter

Developed and introduced in Japan and Korea.  These are available in walking type as well as riding type models.

• The seedlings in mat form are placed in an inclined aluminium tray and are fed by gravity to the planting fork.

• Mechanical feeders located at the lower end of the tray intermittently flick the seedling mat and cause it to slide down.

• A screw mechanism gradually moves the tray from side to side to ensure uniform quantity of seedlings to be picked up by the fingers.

• The riding type machines are generally of six rows while walking type of 2-4 rows is quite common.

• Their coverage is from 0.2 to 0.5 ha day-1 depending upon number of rows and skill of the operator.
