Groundnut Cultivation with Laser Spray (Rain Pipe / Rain Hose)

Introduction

Groundnut (Arachis hypogaea) is one of the world’s most important oilseed and food crops, widely cultivated across tropical and subtropical regions for edible oil, snacks, confectionery products, and animal feed. It is grown extensively in countries such as China, India, Nigeria, the United States, Sudan, Senegal, Argentina, and Brazil, making it a key crop in both developed and developing agricultural economies. Groundnut kernels are rich in protein, healthy fats, vitamin E, B-complex vitamins, calcium, and essential minerals, contributing significantly to global food security, nutrition, and rural livelihoods.

Successful groundnut cultivation depends greatly on proper water management and good agronomical practices. Groundnut is a shallow-rooted crop in its early stages and later develops underground pods through a unique process called pegging. The crop requires light, frequent, and uniform irrigation during germination, flowering, pegging, and pod development stages. Even short periods of moisture stress can result in poor germination, flower drop, reduced pegging, shriveled pods, and yield loss. On the other hand, excess irrigation causes waterlogging, soil compaction, poor aeration, and increased incidence of fungal diseases such as root rot and collar rot.

Traditional irrigation methods like flood irrigation often fail to meet these precise requirements. Flooding leads to uneven moisture distribution, water stagnation, soil compaction, nutrient leaching, and wastage of water and energy. It also increases labor requirements and creates stress conditions that negatively impact pegging and pod development.

To overcome these challenges, farmers are increasingly adopting Rain Pipe / Rain Hose (Laser Spray) irrigation, an advanced micro-irrigation technique designed to deliver uniform, controlled, and gentle water application.

What is Rain Pipe / Rain Hose (Laser Spray) Irrigation?

Laser Spray irrigation, commonly known as Rain Pipe / Rain Hose, is a modern irrigation system manufactured from high-quality polyethylene pipes with precisely laser-punched micro-holes. These micro-holes create a gentle, uniform spray pattern that closely mimics natural rainfall, ensuring even water distribution across the field.

Beside irrigating, Spray Irrigation brings a lot of additional benefits:

Laser Spray (Rain Pipe / Rain Hose) irrigation is technically called Spray Irrigation and it substitutes traditional sprinkler irrigation. It stands out with many benefits:

• Supports Photosynthesis: Clean, healthy leaves are key to efficient photosynthesis. By preventing dust buildup on leaves, the Laser Spray (Rain Pipe) ensures that your plants absorb sunlight more effectively, enhancing growth and yield.
• Gentle on Crops: The Laser Spray (Rain Pipe / Rain Hose) disperses fine water droplets, ensuring that your delicate fruits and flowers aren’t damaged during irrigation. This gentle spray mimics natural drizzle, making it ideal for maintaining healthy crops.
• Boosts Soil Health and Germination: The Laser Spray (Rain Pipe) irrigation keeps the soil porous, which improves air circulation around the roots and enhances seed germination. By spreading water evenly across the soil surface, it also reduces the risk of waterlogging and seepage loss.
• Perfect for Sandy Soil: Sandy soils, notorious for their quick drainage, benefit immensely from the Laser Spray’s (Rain Pipe) thin water distribution on the soil. The water penetrates efficiently, keeping the soil moist without being wasted.
• Washes away Insects: Its rain like watering of the plant washes away the insects resulting in reduction crop protection spray of insecticides.
• Cooling the crop: It cools the crop canopy as well as the soil and thus saves the plants form heat stress.

Why Rain Pipe / Rain Hose for Groundnut?

Groundnut is a close-spacing crop. Since driplines can cover only one or two rows of the crop, it will take an economically unviable quantity of driplines to irrigate a plot of land with drip irrigation system. Laser Spray (Rain Pipe / Rain Hose) overcomes this limitation as each Spray Pipe can cover multiple crop rows (up to 6–7 meters in the two sides together). Thus, Laser Spray Irrigation becomes an economical and highly efficient choice for carrot farmers.

Laser Spray (Rain Pipe / Rain Hose) has other advantages for the groundnut cultivation:

• Maintains uniform moisture across the soil surface.
• Keeps soil loose and friable for easy peg penetration.
• Prevents waterlogging and surface crust formation.

Laser Spray (Rain Pipe / Rain Hose) has several advantages over Sprinkler which is also used for close spaced crops:

Parameter	Laser Spray	Sprinkler
Working Pressure	0.7 kg/cm²	1.5–4 kg/cm²
Pump Required	Lower HP	Higher HP
Electricity Consumption	Low	High
Maintenance	Low (No moving parts)	Higher
Harm to Flowers & Pegs	No	Possible
Soil Compaction	No	Possible

Popular Models of Laser Spray (Rain Pipe / Rain Hose) for Groundnut

Crop Spacing in Groundnut Cultivation

Proper spacing ensures good aeration, healthy plant growth, and efficient pegging.

Recommended spacing:
• Row-to-Row: 30–45 cm
• Plant-to-Plant: 10–15 cm

This spacing supports uniform irrigation coverage and optimal pod development.

Rain Pipe / Rain Hose (Laser Spray) Installation Spacing

Model	Recommended Spacing (m)	Recommended Laying Length (m)
Laser Spray 20 mm	3	50
Laser Spray 20 mm Gold	3	50
Laser Spray 32 mm	6–7	50
Laser Spray 40 mm	6–7	50
Laser Spray 40 mm Marathon	6	100

Results of Rain Pipe / Rain Hose (Laser Spray) Irrigation on Groundnut

1. Improved Germination and Early Growth

Groundnut seeds require uniform moisture during the first 7–10 days. Laser Spray irrigation ensures light and frequent watering, resulting in quick and uniform germination.

2. Better Pegging and Pod Formation

Uniform soil moisture keeps the soil loose, allowing easy peg penetration and healthy pod development without deformation.

3. Higher Yield and Better Productivity

Consistent moisture improves pod size, kernel weight, and oil content. Farmers typically experience 10–20% yield improvement using Driptech Laser Spray systems.

5. Cooling Effect and Heat Stress Reduction

Laser Spray irrigation cools the soil surface during high temperatures, improving crop resilience.

6. Easy Harvesting

Loose and well-aerated soil makes pod lifting easier and reduces labor during harvesting.

• Healthy flowering and pegging
• Smooth pod development
  Uneven moisture can cause flower drop, poor pegging, shriveled pods, and yield loss.

3. How does Laser Spray irrigation help in better pegging?

Laser Spray maintains loose and uniformly moist topsoil, which allows groundnut pegs to penetrate the soil easily. It also prevents soil crusting and compaction that restrict pegging in flood-irrigated fields.

4. Why is Rain Pipe better than flood irrigation for groundnut?

Compared to flood irrigation, Rain Pipe:

• Prevents waterlogging
• Avoids soil compaction and crust formation
• Reduces nutrient leaching
• Saves water and labor
• Improves pegging and pod quality
• Improves yield

Flood irrigation often damages soil structure and negatively affects pod formation.

5. How much water can be saved using Laser Spray irrigation?

Farmers typically report 40–50% water savings compared to flood irrigation due to controlled application leading to better uptake by the plant, reduced evaporation, run-off and seepage.

6. Can Laser Spray irrigation be used in sandy soils?

Absolutely. Laser Spray is ideal for sandy and light soils because it applies water gently and slowly, reducing deep percolation losses and maintaining adequate moisture in the root and pod zone.

7. What pressure is required to operate Rain Pipe irrigation?

Laser Spray works efficiently at low pressure (around 0.7 kg/cm²), requiring a lower HP pump and reducing electricity or diesel consumption.

10. What crop spacing is recommended for groundnut cultivation?

Recommended spacing:

• Row-to-Row: 30–45 cm
• Plant-to-Plant: 10–15 cm
  Proper spacing ensures good aeration, uniform irrigation coverage, and efficient pegging.

11. What is the recommended spacing between Rain Pipes in groundnut fields?

Recommended spacing by model:
