Abstract
Thigmomorphogenesis is a plant response to stimulation or mechanical pressure from outside the plant which affects the growth and development of plants, one of which is how to provide irrigation water. The purpose of this research was to evaluate the effect of thigmomorphogenesis on the crop growth of three types of vegetables, namely spinach, mustard, and water spinach. The vegetables were cultivated in a screen house and irrigated with drip and mist irrigation. The vegetables were planted in rhizobox-type root windows to observe the root growth. The analysis used in this research included t-test and descriptive analysis. The root length of spinach, mustard, and water spinach with drip irrigation were 15.64 cm, 18.97 cm, and 19,25 cm, respectively. The root length of spinach, mustard, and water spinach with mist irrigation were 16.28 cm, 19.22 cm, and 19.33 cm, respectively. Differences in irrigation also affect the parameters of root physiology, root volume, shoot and root wet weight, shoot and root dry weight, and root-shoot ratio. Drip irrigation had a better impact on the growth of spinach and mustard. While mist irrigation resulted a better impact on the growth of water spinach.
