Abstract

Potato plants are propagated vegetatively with tubers. The difficulty of getting potato seeds with tubers is an obstacle in the supply of potato seeds, to overcome these obstacles vegetative propagation with cuttings can be a solution for the supply of potato seeds. This research used a factorial Randomized Block Design (RBD). The first factor is the type of Radix Up consisting of 4 levels, namely Z0 (control), Z1 (Radix Up 1), Z2 (Radix Up 2), and Z3 (Radix Up 3), the second factor is the number of segments consisting of 3 levels namely D1 (number of segment 1), D2 (number of segment 2), and D3 (number of segment 3). Observation variables included: when the roots appeared, plant height, number of leaves, and stem diameter. The results showed that there was an interaction between Radix Up types and the number of segments on the growth of potato shoot cuttings when the roots appeared, but there were no interactions on other observational variables. The Z1D3 treatment (Radix Up 1 and segment number 3) gives the fastest average value, which is the average when the root appears 4.33 days.

Abstract

Potatoes (Solanum tuberosum L.) are carbohydrate-rich crops. Low potato productivity in Indonesia stems from farmers' inadequate access to quality seed potatoes. One solution to this issue is enhancing quality seed potato production, achievable through aeroponic systems. Lighting, whether incandescent or LED, can optimize potato mini tuber propagation in aeroponic systems. Research on lighting's effects on potato growth remains incomplete. This study aims to investigate how lighting color and duration affect mini tuber production of Solanum tuberosum L. PPT4 Zebra using aeroponic systems. Conducted in Jurangkuali, Bumiaji sub-district, Batu, the study employed a split plot design. The main plot consisted of lighting colors (WC): light yellow (WK), white (WP), and purple (WU). Subplots were lighting duration (LP) at 3 hours (LP 3) and 5 hours (LP 5), each replicated four times. Each replication comprised 8 samples, with 18 potato plant cuttings per population. Variables included plant height, stem diameter, leaf count, chlorophyll level, root length, tuber count, tuber diameter, budding seed count, and tuber weight. Data were analyzed using F-tests followed by BNJ tests at a 5% significance level. Results indicated no interaction between lighting color and duration. Purple lighting yielded the highest tuber count and weight, while 3-hour lighting duration yielded superior plant height, stem diameter, leaf count, and root length.
