For example, more watering at the early stage and less watering at the time of flowering can save water and make the flowers bloom better (Li et al., 2014). However, this method requires close monitoring of soil moisture and plant status in order to adjust the irrigation plan in time. Figure 1 Chrysanthemums cultivated in pots, under open field conditions, placed on ceramic bricks (Adopted from Posse et al., 2019) 3.3 Key monitoring indicators To evaluate the irrigation effect, we need to look at several key data. The first is the soil moisture, which can tell us whether the plants are full of water and prevent too much watering (Lin et al., 2011). The growth of plants, such as height, crown width and branch number, can reflect the health of plants (Pansuriya and Kumari, 2024). The quantity and quality of flowers are directly affected by irrigation. If the irrigation method is selected well, the flowers will bloom more and better (Li et al., 2014). Finally, the content of active ingredients, such as flavonoids and chlorogenic acid, is an important standard for judging the quality of Chrysanthemum morifolium and is directly related to its medicinal value (Li et al., 2014; Xu et al., 2021). 4 Effects of Different Irrigation Strategies on the Yield of C. morifolium 4.1 Yield analysis The yield of Chrysanthemum morifoliumwill be significantly affected by irrigation methods. The study found that the amount of water consumption will directly affect how many marketable flower stems can be harvested. In general, daily irrigation of 0.96 to 1.07 cm of water can make Hangzhou White Chrysanthemum produce more high-quality flowers. This result is true in different varieties and planting methods. The frequency of irrigation and the amount of water per irrigation are also important. They will affect how fast plants grow and when they bloom. For example, when irrigated with treated wastewater under different soil drought levels, it is found that more water supply will lead to better growth performance and higher yield (Turan et al., 2015; Gurjar et al., 2023). 4.2 Relationship between water supply during critical growth periods and yield In some key stages, such as when the flower bud is just beginning to form, enough water must be guaranteed. At this time, if there is no water supply, the flowers will be less and the size will be smaller, and finally the total output will be affected (Hassanein, 2015; Pansuriya and Kumari, 2024). Irrigation with saline water will reduce the quantity and quality of flowers, which shows that in these critical periods, it is necessary to ensure not only the availability of water, but also the quality of water (Amarin et al., 2021). 4.3 Balancing water-saving irrigation and efficient production It is very important to save water and ensure the yield in Chrysanthemum planting. In 2024, pansuriya and Kumari used organic fertilizers such as "jeevamrut" and "panchagavya" in their research and found that they can help crops grow well and reduce water consumption. Another way is to use sensors to control the irrigation system. It
