A detailed guide to sesame watering timing and methods, master the latest planting techniques

In daily life, sesame is a common food; it can not only be eaten after being roasted, but also be extracted for oil for consumption, and regular consumption is very helpful for human health. Many people only know that sesame can be eaten, but they do not know that watering is a major difficulty when growing sesame, so when is the right time to water, and how should it be watered? Let us learn about it together.

1. Suitable water content during the sesame growth period

Sesame has different water requirements at each growth stage. From sowing to emergence, the suitable soil water content for emergence is between 15%-25%, and emergence is fastest and the emergence rate is highest at 17%-23%. When the soil water content drops below 14%, the emergence rate will decline as the soil water content decreases, and the emergence speed will also slow down accordingly. When the soil water content drops below 8%, sesame cannot germinate and emerge. When the soil water content is higher than 23%, the emergence rate and emergence speed will also show a downward trend. From emergence to maturity, sesame has a relatively high water requirement: 60%-75% from seedling to early flowering; 75%-85% from early flowering to topping; and 65%-75% from topping to maturity. When the soil water content is below 50%, sesame will shift because of drought damage, and when the water content is above 90%, it is unfavorable for its growth, and there is also a very high possibility of waterlogging damage and seedling death.

2. Watering time

During the sesame growth period, when the soil water content approaches 50% of the maximum water-holding capacity, or when the water content of light soil is below 13%, medium loam is below 15%, and clay loam is below 16%, sesame will show wilting. Under summer drought or autumn drought conditions, around 10 a.m. the upper leaves of sesame can be seen wilting, and after the high temperature at noon they will gradually recover. When this phenomenon occurs, irrigation should be carried out immediately. Irrigation should also take weather conditions into account, and watering before rain or during strong winds should be avoided as much as possible. The most suitable watering times are before 10 a.m. and after 4 p.m. on sunny days.

3. Watering methods

There are three watering methods for sesame: furrow irrigation, border irrigation, and sprinkler irrigation. Furrow irrigation uses water diverted between rows, with a small, gentle flow, so that water seeps into the soil from the furrow, reducing the contact area between the water flow and the ground, preventing ground erosion, and reducing soil compaction. Border irrigation involves building ridges in advance to make borders, so that water flows along the border surface down the slope and gradually moistens the soil. Border irrigation requires controlling the amount of water to avoid water accumulation and root rot. Sprinkler irrigation is an advanced irrigation technique that uses sprinkler irrigation equipment to spray pressurized water into the air and scatter it into droplets to irrigate crops. It has the advantages of economical water use, preventing soil compaction, strong adaptability to terrain, and easy control of water volume.
