Are you growing produce in your backyard vegetable garden but can’t quite get the right amount of water to the plants. You might also be tired of seeing some of the plants dry up while others turn yellow with thirst. On the other hand, you may be looking to upgrade your current irrigation system for better growth of the plants in the vegetable garden. This article will help you find out which is the best irrigation system for a vegetable garden.
1) Drip irrigation system
In a vegetable garden, drip irrigation could be implemented in a simple yet efficient manner. Drip irrigation refers to delivering water droplets directly to the roots of the plants near the roots. This would be made possible by making small perforations on bottles. The bottles could be buried under the soil or above ground. Alternatively, drip irrigation can be done by using perforated pipes in the garden. In addition to saving precious water, drip irrigation ensures a steady flow of water to the plants. What is the best drip irrigation system for a large vegetable garden? Pipes are better for a large garden as they run for longer distances though they would require a pump to push water all the distance.
- Highly effective in saving water in the garden
- Relatively simple to set up the system
- Bottles are locally sourced making it a cheap method
- Ensures a steady and controlled water supply to plants
- Nutrients and fertilizer loss is reduced due to less leaching
- Does not cause soil erosion by splashing or surface run-off
- Works for gardens of different shapes, sizes and levels too
- Weed growth is reduced as water is applied to crops that need it
- It is not labor-intensive
- Setting up the system is time-consuming
- The bottles and tubes may get clogged some times
- Plastic may release harmful chemicals in the soil, causing acidity or worse.
- Tubes may get damaged with time.
2) Sprinkler irrigation system
Sprinkler irrigation method makes use of one or more sprinklers to deliver water to the vegetable garden. In this method, sprinklers are placed strategically depending on the size of the area to be watered and how far the sprinkler throws water. Water is distributed in pipes using a water pump to create the pressure. The sprinkler head is a mechanism that rotates while spraying water within the farm. Water then lands on the plants or soil regardless. Sprinkler irrigation works well in a large area and is one of the best irrigation systems for a large
- Controls dust in the air
- Delivers water over a large area
- Less interference with the land since sprinklers are generally immobile
- Requires very little labor import
- Water amounts can easily be controlled and measured
- Relatively affordable and easy to set up
- It allows for easy mechanization of the garden watering process.
- Water may be sprinkled on the leaves of plants or even on bare land, causing wastage
- Sprinkler pipes may get clogged by sediments
- Relatively costly to operate the system
- High water supply is required for effectiveness
- Could cause splash erosion on land
- The salinity of water could affect the pipes
- Maintenance costs are high in case of a breakdown.
3) Manual irrigation system
Manual irrigation is the most prevalent form and by far the most labor-intensive system of all. It consists of watering plants by the use of a spray bottle, Jerrican, or any other item that is handheld. This method of irrigation is straightforward to implement. It is effective since water is applied where necessary and relatively portable process. Manual irrigation also helps the gardener to save precious water resources that would have been otherwise wasted. The manual method of irrigation is the best irrigation system for a small garden.
- Very efficient in saving irrigating water
- It targets specific plants and selective
- Allows for constant water supply during the growth of plants
- Relatively cheap method of irrigation
- Simple to set up as it uses local materials
- Improves the yield output of the garden
- It is very labor-intensive
- Some plants could get excluded during irrigation
- It is not a controlled method of irrigation
- Water amounts cannot be easily measured
4) Localized irrigation
The localized method of irrigation is one in which a small depth of the soil or root zone is wetted. It is implemented such that water flows at a slow rate, and in small controlled amounts. This irrigation is done frequently to prevent drying. It is the best irrigation method for loose soils and raised vegetable gardens. Equipment used to apply water in the soil is tubes, nozzles, or perforated pipes. Irrigation is done either above or below the soil surface. Distribution channels need to be set up and fitted with water filters that prevent any sediments or dirt particles from entering the supply network.
- Very high efficiency in irrigation is achieved
- Significant water saving due to little evaporation and percolation
- Control of pests and weeds is also promoted
- Higher quantity and quality yields are made due to water and nutrient control
- Nutrients and fertilizers dissolved in the water are applied easily
- Requires very little labor input
- It is a quick method of irrigation of plants
- Works well in a small area, for example, a vegetable garden
- High maintenance costs are incurred
- It is a relatively technical method of irrigation
- Blockages in pipes disrupt the watering process
- Leads to limited root development
- There are high initial costs of the system
To sum up, each vegetable garden is unique in its own way as they come in different shapes, sizes and differ in the plants grown. However, the need for water arguably cuts across the board for all of these gardens, and irrigation is necessary. The best system of irrigation for a vegetable garden has to consider the yields, soil destruction, costs, and labor inputs. In that case, undeniably, drip irrigation is the best irrigation system for a vegetable garden. It leads to better yields, causes less soil destruction, is a cheap method, and relatively low on labor inputs.
