Cut and Bury Motorized weeders for rice production

Effortless Weed Control for Bountiful Harvests

Motorized weeders for rice production are innovative machines designed to efficiently clear weeds from rice fields, significantly reducing labor requirements and costs. These compact units, typically propelled by small petrol motors, can clear one hectare of paddy fields in a fraction of the time it would take manually. They are designed to minimize disturbance to rice crops and soil while uprooting, cutting, and burying weeds. The importance of this technology lies in its capacity to enhance weed control, increase rice grain production, and reduce the need for additional irrigation and fertilizer. It offers a practical and cost-effective solution for smallholder farmers, ultimately contributing to improved food security and economic well-being.

This technology is TAAT1 validated.

Problem

  • Weed Encroachment: Weed encroachment in rice crops, which is a major problem for smallholder farmers, particularly in Sub-Saharan Africa, where manual clearing of paddies is the traditional practice.

  • Labor-Intensive Clearing: Traditional manual clearing of paddies is labor-intensive and costly, leading to decreased efficiency and high labor requirements.

  • Weed-Related Grain Yield Loss: Poor management of weed encroachment is estimated to be responsible for grain yield losses of at least 2.2 million tons per year in Sub-Saharan Africa, with significant economic losses.

  • Environmental Impact: Traditional practices of weed control may have environmental implications due to excessive manual labor and potential herbicide use.

Solution

  • Motorized Weeding Units: The technology involves the use of small-sized motorized units for weeding in between rice crop lines, significantly speeding up the weeding process and reducing labor requirements compared to manual clearing of paddies.

  • Efficiency and Cost Savings: The use of motorized weeding units offers low capital costs, high efficacy, and reduces the labor and cost requirements compared to traditional manual methods.

  • Weed Control and Grain Quality: Mechanized weeding enhances weed control, increases rice grain production, improves grain quality, and reduces the need for additional inputs such as fertilizer and irrigation.

  • Environmental Benefits: The technology offers environmental benefits by reducing the labor and herbicide application, promoting efficient weed control, and improving overall crop management.

Key points to design your business plan

The Motorized weeders for rice production (cut and bury) technology may be of interest to manufacturers, resellers, and users (farmers).

Manufacturers

Manufacturing motorized weeders for rice production (cut and bury) presents a lucrative opportunity to revolutionize agricultural operations. To enter this market, consider the following steps:

1. Identify suppliers or manufacturers of raw materials required for producing motorized weeders tailored for rice production. As key partenaires on that you have: 

    • Centre de Formation et d’Application du Machinisme Agricole (CFAMA), Madagascar
    • Kenya Agricultural and Livestock Research Organization (KALRO), Kenya
    • AfricaHarvest, Kenya
    • National Agricultural Research Organization (NARO), Uganda.
    • Mr. RANDRIAMANANJARA Andriantaolo Elody, fabricator of agricultural equipment in Malaimbandy, Madagascar

2. Determine efficient transportation methods and suitable storage facilities to ensure timely delivery and proper storage of the equipment. The technology is available in Tanzania (Intermech Engineering Ltd, Tel: +255-23-2600668/713-771182/713-485582 ; info@intermech.ws).

3. Factor in expenses such as transportation costs, import duties, and taxes to accurately assess the total investment.

Evaluate costs associated with manufacturing the equipment and identify key customers such as resellers, cooperatives, agricultural associations, and development projects.

Resellers

Selling motorized weeders for rice production (cut and bury) to farmers presents an opportunity to significantly improve agricultural efficiency and reduce labor-intensive tasks. To effectively enter this market, follow these steps:

  • Procure the equipment from reputable manufacturers located in Tanzania (Intermech Engineering Ltd, Tel: +255-23-2600668/713-771182/713-485582 ; info@intermech.ws)
  • Identify efficient transportation methods to transport the equipment from the manufacturers to the desired locations. 
  • Ensure suitable storage facilities are available to securely store the machinery.

Determine the cost of the technology based on the size and specifications of the machinery required for your business. Consider expenses such as transportation costs, import duties, and taxes to accurately assess the total investment.

Potential customers include farmers, development projects, and farmers' cooperatives or associations. Highlight the benefits of using motorized weeders for rice production, such as increased efficiency and reduced labor requirements, to attract potential buyers.

Users

Utilizing motorized weeders for rice production (cut and bury) can significantly enhance farming efficiency. 

Key partners in this endeavor include sellers or managers who handle mechanized equipment for farming. 

When considering the cost of motorized weeders, The price of a hand-operated cut & bury power weeder for rice paddies with a 2-stroke petrol engine that is configured to simultaneously work on two rows is ranging from 550 to 750 USD. Using a two-row power weeder in lowland rice paddies it takes 1 hour to remove weeds from 1000 m2.

To optimize the benefits of motorized weeders for rice production, consider associating this technology with Selective herbicides (pre-emergence and post-emergence) to Enhance Yield and Use Efficiency.

Using motorized weeders for rice production (cut and bury) involves several key steps:

  1. Proper Rice Spacing: Ensure that rice crops are planted in even rows with a spacing of more than 20 cm. This allows for easy maneuvering of the motorized weeders and prevents damage to the crop.
  2. Assess Weed Encroachment: Depending on the level of weed encroachment and the rate of canopy growth, determine how many times the rotary power units need to be used for effective weed control.
  3. Operate Motorized Weeders: This process can be done by one person, especially on waterlogged fields, but for larger areas, two or more workers may be required.
  4. Integrated Pest Management: Consider the use of common herbicides, pesticides, and biological control measures alongside motorized weeding units to create integrated crop protection strategies that enhance yield potentials.
  5. Collective Purchase and Sharing: To make this technology accessible to low-income rice-growing communities in Sub-Saharan Africa, encourage collective purchase and shared use of motorized weeders. Private agricultural service contractors can also be engaged to scale the technology.
