PENGARUH KONSENTRASI PUPUK DAUN TERHADAP PERTUMBUHAN DAN HASIL BIBIT KENTANG (Solanum tuberosum L.) PADA SISTEM AEROPONIK

Potatoes (Solanum tuberosum L.) is one of the vegetable commodities that brings many benefits to be cultivated. Potatoes (Solanum tuberosum L.) are vegetables that are not easily damaged, and are a source of carbonides, calories, protein and vitamins. In addition, Potatoes (Solanum tuberosum L.) is a vegetable favored by the people of the world, making this commodity a clear market both nationally and internationally. The objectives to be achieved from the implementation of this research are as follows: Studying the effect of leaf fertilizer concentration on the growth and yield of potato seeds aeroponic systems Studying the effect of giving certain leaf fertilizer concentration on the growth and yield of potato seeds on the aeroponic system and studying the concentration of leaf fertilizer both on growth and yield of potato seeds on aeroponic systems This study used a randomized block design with one treatment factor. The treatment factors tested were the concentration of leaf fertilizer on potato plants: P1 (0 g / l), P2 (1 g / l), P2 (2 g / l), P3 (3 g / l) and P4 (4 g / l) using 4 replications of each of the 3 samples so that a total of 60 samples. The application of leaf fertilizer to potato plants on the aeroponic system significantly affected the aeroponic system of plants and potato seeds. The application of leaf fertilizer concentrations of 1 g / l, 2 g / l, 3 g / l and 4 g / l to the growth and yield of potato plants tended to be able to increase the growth and yield of potato plants compared to 0 g / l. The application of leaf fertilizer concentration of 4 g / l was able to stimulate plant growth in the observation variables of height, stem diameter, number of leaves, chlorophyll, number of tubers, tuber weight and concentration of Ai were bette
