PENGARUH JENIS PUPUK DAUN TERHADAP PERTUMBUHAN DAN HASIL BENIH KENTANG PADA SISTEM AEROPONIK

Potatoes (Solanum tuberosum L.) is one of the many vegetable commodities that bring benefits to be cultivated. Potatoes (Solanum tuberosum L.) are vegetables that are not easily damaged, as well as a source of carbon dioxide, calories, protein and vitamins. In addition, Potatoes (Solanum tuberosum L.) is a vegetable that is favored by the world community, thus making this commodity has a clear market both nationally and internationally. The objectives of this research are as follows: Studying the effect of leaf fertilizer concentration on the growth and yield of potato seeds in the aeroponic system. Studying the effect of giving concentration of certain leaf fertilizers on the growth and yield of potato seeds in the aeroponic system, and studying the provision of good leaf fertilizer concentrations on the growth and yield of potato seeds in the aeroponic system. This study used a randomized block design (RCBD) with one treatment factor. The treatment factors tested were the application of leaf fertilizer to potato plants: P1 (Growmore), P2 (Bayfolan), P3 (Green tonic), P4 (Mamigro) and P5 (Gandasil D) using 4 replications each of 3 samples so that a total of 60 the sample. The application of leaf fertilizer to the aeroponic system potato plants has a significant effect on plants and the seed yield of the aeroponic system potatoes. The application of P1 (GM), P2 (BN), P3 (GT), P4 (MM), P5 (GD) leaf fertilizers to growth and yield of potato plants tends to increase growth and yield of potato plants compared to administration (GM). The application of leaf fertilizer (GD) is able to spur plant growth on observational variables of height, stem diameter, number of leaves, chlorophyll, number of tubers, tuber weight and better water content
