National Rice Grain Planter / Direct Seeder For Rice - DSR

  • This planter is specifically designed for the Direct Seeding of Rice (DSR), a revolutionary method that eliminates the traditional steps of growing a nursery and transplanting.
  • It ensures direct seeding of rice grains without the need for puddling (wet tillage), significantly reducing water usage and preserving soil structure.
  • The system is engineered to function effectively without leading to waterlogging, which is crucial for healthy root development and better yields.
  • While primarily for rice, the machine is a Multi Crop Planter, suitable for sowing seeds of various crops including paddy (rice), wheat, maize, lentils, and other similar grains.
  • Available in three robust models to suit different farm sizes: the NDSR-9 (9 Rows), the NDSR-11 (11 Rows), and the NDSR-13 (13 Rows).
  • Features an Agitator & Sliding Orifice Type for fertilizer metering and a highly accurate Rotating Disc with cells on its periphery (Inclined Plate) for seed metering.
  • The Row to Row Spacing is standard at 8 inches and is fully Adjustable, allowing farmers to customize planting density based on crop and field conditions.
  • Requires a tractor with horsepower ranging from 35 H.P. for the 9-row model up to 50 H.P. for the 13-row model.

Key Benefits of Direct Seeding (DSR)

Using the National Rice Grain Planter offers significant agricultural, economic, and environmental advantages compared to traditional methods:

  • Substantial Cost Reduction: (a) Saves significantly on labor costs by eliminating the need for nursery preparation, manual transplanting, and puddling operations.
    (b) Reduces fuel consumption as fewer operations are required in the field.
  • Water Conservation: (a) Eliminates the requirement for continuous flooding and puddling, saving a massive amount of water (up to 30-40%) which is vital for sustainable farming.
  • Time and Efficiency: (a) Reduces the overall crop duration by cutting out the time required for nursery raising and transplanting, allowing for timely planting of the subsequent crop.
    (b) Enables farmers to cover more acreage in a shorter time frame, increasing operational efficiency.
  • Improved Soil Health: (a) Prevents the formation of a hardpan layer caused by repeated puddling, which leads to better root penetration and improved soil aeration.
    (b) Contributes to long-term soil sustainability and fertility.
  • Better Crop Performance: (a) The precise seed and fertilizer metering system ensures optimal plant spacing and nutrient placement, leading to uniform germination and healthier crop stands.
    (b) Plants develop a stronger and deeper root system as they are sown directly, offering better resistance to lodging (falling over).
  • Adaptability: (a) The machine’s adjustable row-to-row spacing makes it highly versatile, allowing farmers to quickly switch between various crops and optimize plant density as needed.

Usage

The National Rice Grain Planter is designed for straightforward operation and integration with commonly available farm equipment, ensuring smooth field preparation and planting.

Simple Operational Principle (DSR)

  • No Puddling Required: Unlike traditional rice cultivation, this machine works on dry or semi-dry, well-tilled soil, eliminating the complex and water-intensive process of puddling.
  • Single-Pass Sowing: The planter performs multiple functions simultaneously in a single pass opening the furrow, dropping the seeds and fertilizer at the required depth, and covering them up.
  • Reduced Field Operations: By combining seeding, fertilizer application, and soil covering, the total number of passes required across the field is minimized, saving time and fuel.

Tractor Compatibility & Power Requirements

The following table details the necessary tractor horsepower (H.P.) for each model to ensure efficient and effective operation:

Model Name Rows Minimum Recommended Tractor H.P. Primary Use Case
NDSR-9 9 35-40 HP Small to Medium Farms
NDSR-11 11 40-45 HP Medium to Large Farms
