Tomato Plants Watering and Irrigation: Complete Guide | Rivulis (2024)

Tomato cultivation is a delicate process that requires precise irrigation to ensure healthy growth and maximum yields. Choosing the right irrigation method and adhering to best practices are crucial for successful tomato production. In this article, we will discuss various tomato irrigation methods, focusing on the advantages of drip irrigation and the benefits of using Rivulis drip irrigation systems. We will also provide insights into best practices for tomato plant irrigation.

Tomato irrigation methods

Furrow irrigation

This is a traditional method involving small channels or furrows between rows of tomato plants, allowing water to flow through and reach the root zone. While inexpensive, furrow irrigation can lead to water wastage due to evaporation and runoff. As in many other cases, furrow irrigation has a lot of disadvantages compared to other methods of irrigation.

Besides being inefficient in water use, it also presents some challenges such as water logging and sub-optimal conditions, both before and after irrigation application.

Water and nutrient leaching are also some of the major drawbacks of this irrigation method.

Sprinkler irrigation

Water is distributed through a network of pipes and sprinklers, often via center pivot / lateral move irrigation, providing even coverage across the field. Sprinkler irrigation can be more efficient than furrow irrigation but may increase the risk of foliage diseases due to wet leaves. Despite its better water distribution uniformity, sprinkler irrigation inevitably waters the whole field, regardless of the plant rows themselves or the relevant root zone. Tomatoes are sensitive to foliage wetting, and the inferior accuracy of sprinklers makes them a less than perfect choice for your tomato crop.

Drip irrigation

The most efficient and effective method for watering tomato plants is drip irrigation, which delivers water directly to the root zone, minimizing water wastage and promoting healthy plant growth. It provides water and nutrients on demand. With minimum waste and maximum accuracy, the best results can be achieved and return on investment is best assured.

Advantages of drip irrigation for tomatoes

Drip irrigation has emerged as one of the most efficient methods for irrigating tomatoes. It offers numerous benefits, contributing to higher yields and more sustainable production. Let’s drill down on some of the major benefits of drip irrigation for tomatoes.

Water conservation

Drip irrigation systems can save up to 50 per cent more water than traditional irrigation methods such as furrow, making it an environmentally friendly option. With low flow rate emitters, water is applied according to plants’ needs, and exactly where it is needed. Without unintentional wetting of the area between the rows and without water logging or leaching, the plant’s environment is brought closer to optimum.

Improved yields

Studies have shown that drip irrigation can increase tomato yield by 20–90 per cent, depending on the region and growing conditions. With an improved water-to-air ratio in the soil and a much more precise application of water and fertilizers, the crop can more easily reach its genetic yield potential.

The study above shows that with drip irrigation, tomato yield was 48% higher with drip irrigation.

Reduced disease and pest pressure

Tomatoes, along with many crops in the Solanaceae family, are extremely sensitive to leaf disease.

Moisture on the canopy from overhead sprinkler irrigation can lead to disease which will cost you in yield and quality. Drip irrigation delivers the right amount of water to the root of the plant, preventing water from gathering on the leaves.

By delivering water directly to the root zone, drip irrigation reduces the chances of foliage diseases and pest infestations associated with excess moisture on the leaves.

Fertilizer efficiency

Drip irrigation allows for the precise application of fertilizers, ensuring that nutrients are delivered directly to the root zone, resulting in better nutrient uptake and reduced fertilizer wastage.

Best practice for tomato irrigation

To ensure successful tomato growing, it is essential to follow best practices for irrigation and fertigation, such as:

• Monitoring soil moisture: Regularly check the soil moisture levels to determine the appropriate watering frequency and duration.
• Maintaining uniform water distribution: Ensure that your irrigation system provides uniform water distribution across the field.
• Fertilizer application: Utilize fertigation (applying fertilizers through the irrigation system) for efficient nutrient delivery directly to the root zone.
• Regular maintenance: Regularly check and maintain your irrigation system to ensure optimal performance.
