Irrigation Management of Wheat Crop
Wheat is a staple crop that is grown worldwide for its nutritional benefits. Proper irrigation management is essential for the growth and yield of wheat crop. Inadequate water supply can lead to stunted growth, yield loss, and poor quality of wheat grains. This article will cover the basics of irrigation management of wheat crop.
Factors affecting irrigation management
Several factors can affect the irrigation management of wheat crop, including the soil type, climatic conditions, crop stage, and water availability. The availability of water can vary based on the source of irrigation, such as rainfed or from underground water resources. The topography of the land also influences the irrigation method, such as furrow irrigation, sprinkler irrigation, or drip irrigation.
Crop stage
Timing of irrigation is crucial, and it varies based on the crop stage. The critical stages of wheat crop for irrigation include:
– Tillering stage: the stage when the first leaves emerge from the soil.
– Jointing stage: the stage when the stem starts to elongate and new leaves emerge.
– Booting stage: the stage when the head of the wheat plant first emerges from the stem.
– Heading stage: the stage when the wheat head starts to emerge, and flowers open.
– Grain filling stage: the stage when the wheat grains start to form and grow.
These stages are essential to understand in wheat crop irrigations as the water requirements vary for each stage. Also, an adequate supply of nutrients like nitrogen, phosphorus, and potassium with irrigation can significantly boost the yield of the wheat crop.
Irrigation methods
There are four main irrigation methods used for wheat crop, each with its advantages and drawbacks. The irrigation methods in common are:
1. Furrow Irrigation: a simple method where channels are dug between the crop rows and filled with water. Once the soil has absorbed the water, farmers can shape furrows between the rows of crops to move the water to the next section of the field. This method is labor-intensive but more affordable than some others.
2. Sprinkler Irrigation: a high-pressure system that sprays water over the wheat crop. It can be expensive to install but is very useful for watering large areas quickly. This method is commonly used in regions with limited water availability.
3. Drip Irrigation: a more efficient system for delivering water directly to the wheat crop roots. It requires an underground network of pipes and emitters. Drip irrigation is costly to install but can be more efficient in the long term than other techniques.
4. Subsurface Irrigation: Similar to drip irrigation, subsurface irrigation delivers water under the soil surface, to root level. And it has proven to be useful in areas with low soil moisture capacity.
Proper irrigation management is essential for the success of wheat crop growth and yield. Farmers who decide to plant wheat should be aware of the water requirements of the crop and the availability of irrigation resources. Irrigation techniques should be selected based on the crop stage and the local conditions. An effective irrigation system can significantly increase the yield of wheat crop and help meet food consumption demands.
