Modular DSR Seeder
Precision Seeding for Rice and Beyond

At APV, we have used our globally proven pneumatic seeding technology to develop an advanced modular seeder capable of Direct Seeding of Rice (DSR) in both wet and dry fields. Beyond rice, this versatile seeder handles multiple crops—including mungbean, soybean, peanut, chickpea, wheat, and more—making it a true multi-seed solution.

The system for direct seeding rice consists of the following compontents:

Main Frame + DSR W Module

robust and adaptable frame with module for direct rice seeding in wet fields.

Main Frame + DSR D Module

robust and adaptable frame with module for direct rice seeding in dry fields.

Pneumatic Seeders + control module

Compatible with APV PS 120 M1, PS 200 M1, PS 300 M1 for precise seed placement

DSR W for wet fields

Rice Direct Seeding Machine for seeding in wet fields - "W" stands for "Wet".
Working widths: 1.50 m / 2.0 m / 2.5 m Number of rows: standard 8, optional up to 16.

The DSR W module is mounted on the basic DSR frame with a 3-point hitch for the tractor or machine carrier, which also supports the pneumatic seed drill PS.

The main components of this module are:

  • A floating leveling board that ensures optimal preparation of the sowing surface on wet fields. With a specialized mechanical adjustment system, it continuously adapts to the field's surface. The leveling board also incorporates elements that create drainage channels on the soil surface.
  • Depth-adjustable row openers, positioned behind the leveling board, prepare the sowing furrow at a depth of 0.5 to 3.0 cm.
  • A dedicated sowing head precisely places the seed into each row.
  • A mechanism with sliding elements is used to cover the seeds in the row.

DSR D for dry fields

 

Rice Direct Seeding Machine for seeding in dry feilds - "D" stands for "Dry".
Working width: 2,50 m Number of rows: standard 8 / optional up to 16

The DSR D module is mounted on the basic DSR frame for a 3-point hitch to the tractor or machine carrier. On the main frame is mounted pneumatic seed drill PS.

The key components of DSR D module include

  • Specially designed furrow openers, made from spring tines and a seed shoe.
  • An additional pair of harrows is installed to ensure proper seed coverage in the row, .
  • The gauge wheels ensure precise depth control.

 

 

Operating Principle

The DSR (Direct Seeder Rice) machine is mounted to a tractor or implement carrier via a three-point hitch. The integrated pneumatic seeding system (PS) ensures precise seed metering through eight, up to 16 distribution lines.

Configuration Options:

  • Equipped with steel floatation elements DSR W; for wet seeding in paddy fields

  • Or fitted with spring tine openers DSR D; for dry field seeding operations 

 

Wet Seeding Method:

  • The leveling board efficiently smooths out uneven terrain in waterlogged fields, creating a uniform, well-prepared surface for optimal seed placement.

  • Furrow openers mounted directly on the module DSR W attachment prepare planting furrow.
  • The APV PS150M1 - PS300M1 air-flow system accurately places precisely measured seeds quantity into the prepared planting furrow through specialized seed nozzle.
  • A covering mechanism closes the furrow to prevent seed loss (e.g., from birds).

 

Dry Seeding Method: 

  • Row seeding in properly prepared dry field conditions.
  • Module DSR D is equipped with special system of spring tines and seeding shoes for forming seeding furrows and optimal soil penetration.
  • The APV PS150M1 - PS300M1 air-flow system accurately places precisely measured seeds quantity into the prepared planting furrow through seeding shoe.
  • Seed coverage for preventing seed loss (e.g. from birds) is ensured by pair of tines harrow in each row.
  • Gauge wheels maintain consistent seeding depth for uniform crop establishment.

EXACT

  • Precise, accurate and variable seeding rates 0,5 – 250 kg/ha.
  • Advanced, user-friendly computerized control modules guarantee optimal precision and efficiency in seeding.
  • Auto shut-off & restart of the sowing roller at headlands.
  • Optional speed sensors enable automatic, speed-dependent seed dosing.

VERSATILE

  • Crop versatility: Designed for the sowing of not only rice but also a variety of other crops, including soybeans, mung beans, peanuts, and more.
  • Configurable working widths: 1.5 m | 2.0 m | 2.5 m
  • Row configuration: 4-16 rows with adjustable inter-row spacing
  • Universal field adaptation: Performs equally in both wet and dry field conditions
  • Power options: Compatible with all brands tractor mounting or other motorized machine carriers. Required 12V power connection to run all machine functions.

 

YOUR BEST INVESTMENT

  • Exceptional cost-to-performance ratio.
  • Comprehensive Standard Package: All functional components included in the base delivery scope.
  • High Operational Efficiency: Sowing capacity of up to 10 hectares per day.
  • Single-Operator Control: Requires only one person to manage seeding.
  • Complete operation from driver’s seat
