Mechanization in crop establishment
• 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.
Mat type seedling transplanter
? It consists of a reciprocating tray, ground wheel, flat, a planting unit and a small engine as a power unit.

? The seedlings in mat form are placed in an inclined aluminium tray and are fed by gravity to the planting fork.
Plate 2: Paddy transplanter (side view)
? 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.
Plates 3: Mechanized Paddy Transplanting
? 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.

Efficiency of Paddy Transplanter
Machine uses mat type seedlings and it can transplant 1.2-1.5 ha/day with the help of 5 persons by working at a speed of 1.1-1.5 km/h. It saves about 65% labour and 40% cost of operation as compared to manual transplanting. The cost of machine is Rs. 5,000/- The cost of operation is Rs. 2,000/ha as compared to Rs. 3,000/ha by traditional methods.
In manual transplanting, you require about 8 people to cover an area of two acres per day. Here, you require just two people (a driver and helper to place the seedlings) and they can transplant one acre in just 70 minutes.
