Smart Irrigation in Chickpea Cultivation: Benefits and Practical Notes
Chickpea cultivation is one of the important crops in Iran, requiring precise water management to achieve optimal yield. The use of smart irrigation for chickpeas is no longer a luxury option, but a necessity for modern farmers seeking to reduce costs and increase efficiency. Below, we thoroughly examine the benefits of this irrigation method.
Introduction to smart irrigation and its necessity for chickpeas
Chickpea is a plant sensitive to water deficiency, especially during critical phenological stages. Over-irrigation via sprinkler systems, besides wasting water, causes fertilizer leaching and root diseases. In contrast, compact and smart drip irrigation delivers water precisely to the plant root zone. This precision ensures the plant is maintained at optimal moisture levels, minimizing water stress.
The intelligence in this system is achieved through the use of soil moisture sensors, automatic controllers, and sometimes meteorological data. This technology helps farmers adjust irrigation timing and volume based on actual plant needs, rather than mental estimates. This paradigm shift from calendar-based to data-driven irrigation is the core of its economic and environmental benefits.

Key benefits of smart irrigation in chickpea cultivation
1. Significant increase in yield and seed quality
One of the most significant advantages is increased yield. When chickpea roots have unlimited and regular access to water, secondary branch growth and pod formation proceed more effectively. Studies indicate that precise water management can increase chickpea yield by 15 to 20 percent. In addition to quantity, grain quality regarding uniformity in size and protein percentage also improves, as water stress is not induced in the plant.
2. Significant Water Conservation
Drip irrigation and subsurface drip irrigation (SDI) are methods that wet only a portion of the soil surface. This significantly reduces evaporation from the soil surface. Furthermore, by using smart systems, over-irrigation, which causes leaching of pesticides and fertilizers from the rooting zone, can be prevented. In fact, you use exactly the amount of water the plant needs, no more.
3. Reduction in Labor and Energy Costs
Smart systems eliminate the need for the farmer’s continuous presence in the field to open and close valves. One person can manage multiple fields using a mobile application or control panel. The reduction in pressure in smart and automatic systems directly leads to decreased electricity consumption for pumps and, consequently, lower energy costs.
4. Improved Fertilizer Management (Fertigation)
One hidden but powerful advantage of drip irrigation is the ability to inject nutrients through water. Water-soluble fertilizers can be placed directly next to the plant’s active roots. This method enhances nutrient uptake and prevents salt accumulation at the soil surface, which is common in rainfed irrigation. For chickpea cultivation, which is sensitive to micronutrients, this benefit is critical.

Drip tape as the backbone of smart chickpea irrigation
Among the various types of drip systems, Drip tape is the most popular option for growing corn, beans, and chickpeas due to its scalability, rapid installation, and cost-effectiveness. Drip tape allows you to prepare the irrigation system on the ground in the shortest possible time.
The benefit of making drip tape smart lies in its combination with pressure and flow controllers. You can control lateral lines individually and even stop other lines if a problem occurs in one, reducing water waste. Additionally, the smart design of the distribution network ensures that pressure remains stable at the end of the lines and irrigation uniformity is maintained throughout the entire row.
Transitioning from manual to smart irrigation
Some farmers start by installing manual pumps and then upgrade their system. This upgrade can be done in a step-by-step manner:
- Start with a manual pump and manual scheduling.
- Install a digital timer to eliminate the need for physical presence to turn the system on or off.
- Connect soil moisture sensors and transition from time-based to demand-based irrigation.
- Achieve full farm coverage through automation and remote monitoring.
This evolutionary path reduces the risk of investment for water-scarce farmers and enables gradual learning of technology.
Practical points for installing and managing smart irrigation for chickpeas
To benefit from all the advantages, you must pay attention to the following points in installation and operation:
- Planting depth: Drip tape is usually placed on the surface, but subsurface irrigation is also feasible for chickpea, offering better weed control. The choice depends on soil type and region.
- Emitters spacing: A spacing of 20 to 25 centimeters is usually suitable for chickpea. This distance must be calculated based on the emitter flow rate and the water requirement at each growth stage.
- Full filtration: A smart system without proper filtration will quickly clog the emitters. Using a screen or sand media filter (disk or sand filter) based on water quality is vital.
- Use of a pressure gauge: To monitor system performance, it is recommended to install pressure gauges at the beginning and end of main lines to detect pressure drops caused by blockages or leaks at an early stage.
- Pre-irrigation field management: Initial soil preparation (leveling) is essential to prevent water accumulation in furrows for the tape method. Excess furrows can cause lateral drainage and water loss.
Additionally, the use of precise performance management helps farmers accurately calculate water stability coefficients and determine irrigation quantities at each stage, thereby preventing the waste of resources.

Answers to Frequently Asked Questions (FAQ)
Is smart irrigation cost-effective for small-scale pea farms?
Yes, even for small farms. Tape systems have lower costs than permanent drip systems, and given the high yield of peas, the return on investment is quick. Additionally, reducing the risk of water shortage is critical for small farms, which have a lower risk tolerance.
What is the best time to irrigate peas in a smart system?
The smart system should operate based on sensors. However, generally, the best time for irrigation is early morning to reduce evaporation. Your system should be scheduled to operate during cooler hours of the day, unless sensor data indicates an immediate need at other times.
Are tape systems usable for other crops?
Yes, many farmers adjust their farms for this purpose. For example, if you have sown pea seeds alongside bean seeds, you can use the tape for the beans. The general principles of drip are similar; only the spacings and water volumes change according to the crop.
What is the optimal drip spacing for peas?
Depending on the tape width, it is usually 20 to 25 centimeters. If your farm is row-based, these spacings must align with the row spacing to ensure uniform coverage.
Does smart irrigation reduce root diseases?
I support this argument. By creating a wetter zone and a drier zone around the roots, the environment becomes less ideal for root-rot fungi. Overhead sprinkler irrigation creates high moisture and a uniform environment, which is ideal for many pathogens.
Conclusion and Final Recommendations
Transitioning chickpea cultivation to smart irrigation systems is a smart investment for the future. Its benefits range from water savings and reduced labor costs to increased yield and seed quality. Choosing a Irrigation system type that suits your land conditions, soil type, and budget is the key to success.
Starting with a section of the farm, testing the technology, and then expanding it to other sections is a low-risk and efficient solution. Also, always choose drip emitters from Drip tape components Use high-quality, German-grade components to ensure long-term system performance. Considering forward-looking resource management, smart irrigation is no longer an option but an essential requirement for sustainable chickpea farming.
