Effect of slope level on the growth of the tropical Kudzu (Pueraria javanica) applied as hydroseeding formula on landslide soil

Research on Hydroseeding is considered few in Indonesia. The application of this technique is possible for landslide management. to analyze the effect of slope and hydroseeding formula on the percentage growth, germination height, and number of leaves of Poeraria javanica planted on landslide-used soil media. This research was conducted in the Central Laboratory and the green house of the Malang Institute of Agriculture in March-July 2020. The soil media used were obtained from landslides in Ngantang, Malang Regency. A total of 5 kg of media was put into the plastic boxes. Then the boxes were placed on a shelf with a slope of 30°, 50°, 70°. The Tropical Kudzu seeds obtained from the market were mixed with compost, soil conditioner, guar gum, water to form a Hydroseeding formula. The formula was sprayed onto the planting medium. The results indicated that the slope level was significantly affected the growth percentage (P = 0.018), shoot height (P = 0.015), and the number of leaves (P = 0.010). The study indicated that the growth percentage, shoot height, and the number of leaves of the Tropical Kudzu (Pueraria javanica) were significantly affected by the slope level and hydroseeding treatment. The highest growth was found on 50° slope, while the lowest was on a slope of 70°. The highest sprouting height was at a slope of 50° while the lowest was at a slope of 70°. The highest number of leaves was at a slope of 50°, while the lowest was on a slope of 30°. Thus, the Tropical Kudzu (Pueraria javanica) can be used as a pioneer plant in land reclamation.
