Tractor-Mounted Potato Planter

A tractor-mounted potato planter drops seed tubers and basal fertiliser into ridge furrows in a single pass, automating the most labour-intensive operation in commercial potato cultivation. Indian-developed designs combine mechanical seed metering, fertiliser application and ridge formation on a single three-point-linkage frame.

Function

A vertical or horizontal seed-cup belt picks up individual seed tubers from a hopper and drops them at controlled spacing into a furrow opened by a shoe-type opener. A separate fertiliser hopper meters basal fertiliser into the same or an adjacent furrow. A pair of furrow-closing discs or a small ridger (Ridger Plough) covers the seed and forms the planting ridge.

Design and specifications

ICAR-CIAE Bhopal unveiled a tractor-operated mulch-layer-cum-planter in 2025 with 1-metre working width, 0.5-0.9 m row spacing, 0.2-0.6 m plant spacing, an effective field capacity of 0.2 ha/hour at 1.7 km/h and 74% field efficiency. The unit cut human-labour use by 26 person-days per hectare (about 89%) and operational cost by about 43% (around Rs 6,600 per hectare in the trial). The PAU/Punjab tractor-mounted vertical-belt paired-row potato planter operates at approximately 2.5 km/h with 600-710 mm row spacing and 200-280 mm plant spacing.

Operation

The field is prepared with a Rotavator and the planter follows. Seed tubers are loaded into the hopper; row spacing and depth are set with the planter frame. Several Indian designs combine planting with plastic-mulch laying for high-value vegetable crops.

Subsidy and adoption

The planter is listed under SMAM and state horticulture-mission equipment lines. Adoption is highest in Punjab, Uttar Pradesh, West Bengal, Bihar and Gujarat, where commercial potato cultivation is concentrated.
