Furrow Irrigated Raised Bed Wheat Production

Smart Irrigation, Bountiful Harvests

This technique involves creating raised beds, 40-130 cm wide and 10-20 cm tall, with furrows 20-50 cm wide in between. Crops are planted on top of the beds, and water is directed to the furrows, ensuring even irrigation and maintaining optimal soil moisture. The engineered surface enhances rainwater collection, reducing soil erosion. Capillary forces and evapotranspiration prevent waterlogging, protecting wheat crops. This method is effective only with specific varieties of irrigated wheat. In Ethiopia, these varieties include Amibera, Ga’ambo, Kakaba, Fentale-2, Shorima, Dandaa, and Ogolcho. In Nigeria, the varieties are Attila, Reyna 28, Norman Borlaug, Pastor, Imam, and Kauz. In Sudan, suitable varieties include Goumria, Zakia, Imam, Elnielain, Bohaine, Argine, Akasha, Zaidab, Ageeb, Ashri, Amel, and Al-Shibak.

This technology is TAAT1 validated.

Problem

Excessive Water Consumption in Traditional Flood Irrigation
Traditional flood irrigation methods result in the wasteful use of large volumes of water. This not only strains limited freshwater resources but also drives up production costs for wheat farmers.
Risk of Soil Water Logging and Salinization
Blanket flooding in traditional methods can lead to water logging, where excess water accumulates in the soil, suffocating plant roots. Additionally, it increases the risk of salinization, as salts in the soil are drawn up, potentially damaging crops.
Inefficient Fertilizer Use
In traditional methods, it's challenging to apply fertilizers precisely, often leading to overuse or uneven distribution. This inefficiency not only drives up production costs but can also harm the environment.
Suboptimal Soil Moisture and Crop Productivity
Inadequate control over soil moisture levels in traditional methods can lead to suboptimal conditions for crop growth. This can result in lower yields and reduced overall productivity for wheat farmers.
Limited Freshwater Supply for Agriculture
Access to freshwater is a critical issue for agriculture, particularly in dryland areas. The limited supply of freshwater for irrigation poses a significant challenge for wheat farmers, impacting their ability to achieve higher yields and drought resilience.

Solution

Controlled Furrow Irrigation: Implementing controlled furrow irrigation techniques significantly reduces water consumption by directing water only to the necessary areas, optimizing soil moisture levels for wheat crops.
Raised Bed Cultivation: Raised bed cultivation prevents water logging and salinization by promoting drainage and allowing roots to access oxygen, safeguarding crops from these damaging effects.
Precision Fertilizer Application: Utilizing precision techniques allows for accurate and efficient fertilizer distribution, ensuring crops receive the nutrients they need without excess, reducing costs and environmental impact.
Engineered Soil Surfaces: Implementing engineered surfaces with raised beds and controlled furrows ensures optimal soil moisture levels, promoting healthy crop growth and maximizing yields.
Rainwater Harvesting and Controlled Irrigation: Employing rainwater harvesting techniques in combination with controlled irrigation practices helps utilize available freshwater resources more efficiently, enhancing drought resilience and overall crop production.

Key points to design your project

Furrow Irrigated Raised Bed Wheat Production empowers women by reducing irrigation labor and promotes climate-smart agriculture through water conservation and reduced erosion. This contributes to SDGs 2 (Zero Hunger) and 13 (Climate Action).

Partnerships: Collaborate with local research institutions, agricultural extension services, and farmer cooperatives to leverage their expertise, knowledge, and connections. Consider reaching out to the International Institute of Tropical Agriculture (IITA) for potential partnerships, as they promote Furrow Irrigated Raised Bed Wheat Production.
Training: Conduct training sessions for farmers on constructing raised beds, managing furrow irrigation, and implementing best practices for Furrow Irrigated Raised Bed Wheat Production. Costs may vary depending on the program's length and complexity, averaging around $50-100 per farmer for a basic training program.
Land Suitability: Evaluate land slope, aiming for slopes ideally below 3%, and assess soil texture (sandy, loamy, or clayey) to ensure compatibility with Furrow Irrigated Raised Bed Wheat Production.
Seed Selection: Choose drought-resistant, high-yielding wheat varieties suitable for furrow irrigation, considering local preferences and disease resistance.
Marketing Plan: Develop a comprehensive strategy for selling the increased wheat production, ensuring market access and profitability for farmers.
Cost Estimation: Calculate the total costs involved, including training, seeds, and tools. Anticipate expenses of approximately $5-10 per kg for seeds, $10-20 per farmer for basic hand tools, and an overall cost of just under $300 per hectare for labor and inputs for irrigated raised bed cultivation.
Water Management: Determine the most suitable water management method based on the project's requirements and budget constraints. Consider options such as basic canal systems or drilling wells, each with associated costs and benefits. Ensure efficient water use to minimize irrigation expenses and promote sustainability.
Implementation: Begin implementing the Furrow Irrigated Raised Bed Wheat Production project, constructing planting beds and irrigation furrows using locally available tools. Monitor and manage water usage to optimize crop growth and minimize costs over multiple growing seasons. Plan for recurrent costs associated with raised bed reconstruction every three growing seasons.

Inspect Field and Determine Slope:
- Before starting, visually inspect the field to identify the slope and direction of water flow.
- If the slope is less than 0.5%, design the bed-furrow system to be parallel with the slope. If greater than 0.5%, align it with the contours.
Prepare the Soil:
- Clear the field of rocks, debris, and tree trunks.
- Till the soil to a depth of 20cm and harrow to break up large clumps.
Install Distribution Channel and Drainage Collector:
- At the higher end of the field, install a distribution channel to evenly spread water.
- At the lower end, set up a drainage collector to prevent water accumulation.
Create Raised Beds and Furrows:
- Use appropriate tools to shape the soil into raised beds (40-130 cm wide, 10-20 cm tall) with furrows (20-50 cm wide) in between.
Level Beds and Optional Covering:
- Ensure the beds are level for uniform irrigation. Optionally, cover the beds with mulch or plastic sheets to maintain the engineered surface.
Optimize Crop Growth and Rotation :
- Monitor soil moisture and nutrient levels throughout the growing season for optimal conditions.
- Harvest when ready, benefiting from higher yields and returns on investment.
- Consider rotating crops like rice, cotton, or legumes alongside wheat for diversified agricultural productivity.
