What is the water suitable for the growth and development of sorghum?

What is the water suitable for the growth and development of sorghum? Please introduce the soil moisture content 15% to 20% before sowing. The water demand at the seedling stage accounts for 8% to 15% of the total water demand during the whole growth period. When the soil water content is 50% ~ 65% of the maximum field water holding capacity, it is the most suitable. Proper control of soil moisture at seedling stage is beneficial to the rational establishment of vegetative organs. The water requirement at jointing and booting stage accounts for 33% and 35% of the total water requirement during the whole growth period. The water requirement at heading and flowering stage accounts for 22%-32% of the total water requirement during the whole growth period. At this time, water shortage increases the number of sterile flowers, reduces the vitality of pollen and stigma, and leads to poor fertilization. Too much water at heading stage will often lead to the degradation of some branches and spikelets under the spike. The sensitivity of sorghum to water is in the following order: jointing and booting stage, heading stage, flowering stage, filling and mature stage. Once drought occurs in the filling stage, it will lead to the decrease of grain yield. In the later stage of grain filling, too much soil moisture will cause greedy green late ripening, and even suffer frost damage.
