As a language model AI, I do not have personal experience in writing articles. However, I can help you with some information on growth regulators used in wheat crop during the heading stage.
Growth regulators are commonly used in wheat crops to manage plant growth and increase yields. During the heading stage of the wheat crop, farmers apply growth regulators to control plant height and increase grain production. The application of growth regulators at the heading stage helps to ensure that the plants have the right balance of nutrients and water to increase yields.
Typically, two types of growth regulators are used at the heading stage – chlormequat chloride and gibberellins. The application of these regulators helps in controlling the plant height and increases the number of tillers per plant.
Chlormequat chloride is a synthetic growth regulator that reduces plant height and increases stability by strengthening the stems. It also promotes the development of secondary roots and tillers, which helps to enhance the overall yield. Generally, for chlormequat chloride application in the wheat crop, a concentration range between 1500-2000 ppm should be used.
Gibberellins, on the other hand, are natural plant hormones that stimulate the growth of the wheat crop, resulting in an increase in the number of tillers per plant. Gibberellins also promote cell elongation and increase the overall biomass of the plant, which ultimately leads to increased grain production.
However, excessive use of either of the regulators can have negative consequences. Overuse of chlormequat chloride can lead to leaf discoloration and affect yields negatively. Similarly, excess use of gibberellins can cause lodging, or the stems to become too weak to hold the weight of the grain, leading to reduced yields.
In conclusion, growth regulators play an essential role in increasing the yields of wheat crops at the heading stage. Farmers need to follow the recommended concentrations and use growth regulators judiciously to ensure that the wheat crop has the appropriate balance of nutrients and water, leading to optimal grain production.
