Abstract
Brassica oleraceae var. acephala) often also called to as Chinese broccoli or Chinese kale, is included in the group of leaf vegetable plants that have high economic value. Kailan plants contain nutrients that are quite complete and very good for health. In 100 grams of fresh kailan plants contain vitamin A, vitamin B1, fat, calcium, iron, magnesium and phosphorus. Increased air temperature and extreme weather that causes drought have an impact on decreasing food production. The decrease in the availability of soil water content is an environmental condition where plants do not receive sufficient water supply, so that plants cannot carry out the growth and development process optimally. This study aimed to evaluate the growth and yield of kailan plant on dusty clay soil for various field capacity water contents. The application of water supply is carried out at 60%, 40% and 20% of the water content of the field capacity for kailan plants during the growing period to harvest. The results obtained that the water content of field capacity in dusty clay: 36.50%. The decrease in the water content of the field capacity from 60% to 40% and 20% resulted in a decrease in plant growth respectively- plant height 9.07% and 39.95%, leaf area 43.42% and 60.09%, and fresh weight 46.86% and 78.53%.
