As wheat farmers, it is essential to understand the importance of the last irrigation in the crop cycle. When done correctly, this final irrigation can significantly impact the quality and yield of the wheat crop. The optimal time for the last irrigation varies based on several factors, including the soil type, weather conditions, and growing season.
In general, farmers should aim to apply the last irrigation when the wheat is in the beginning of the milk stage, which is about two weeks before the harvest time. During this time, the wheat plant is still in its grain-filling phase, and any water stress can significantly affect the grain quality. The last irrigation at this stage helps the wheat plants continue to grow and fill the grain, increasing both the yield and quality.
It is crucial to note that the timing for the last irrigation may also vary based on the location, climate, and irrigation system used. In areas with high precipitation rates, the last irrigation can be delayed or altogether skipped. However, in arid regions, it is necessary to time the last irrigation correctly to avoid moisture stress and optimize harvest.
Farmers should also be mindful of the weather conditions during the growing season. In dry seasons, farmers should consider irrigating a week later than recommended to avoid the risk of yield loss. However, during wet seasons, the last irrigation should be done earlier to prevent waterlogging and crop disease.
In conclusion, farmers should aim to apply the last irrigation to wheat crop when the grain is in the beginning milk stage. However, it is essential to note that the timing for the last irrigation varies based on environmental factors such as soil type, climate, and irrigation system. Farmers should keep in mind the weather conditions and adjust the time of the last irrigation accordingly to ensure optimal growth and quality of the wheat crop.
