Pengaruh Komposisi Media Tanam Hidroponik Agregat terhadap Produksi Benih G0 Tiga Kultivar Kentang ( Solanum tuberosum L.)

Abstract

ABSTRAK The research objectives were 1) to know the influence of planting media composition of agregate hydroponic on the number of G0 tuber that produced by three potato cultivars, and 2) to determine the best planting media composition for each cultivar. The research was conducted at Greenhouse of PD Jaya Mandiri Farm and Institute of Agricultural Technology Assessment (BPTP), West Java from May to September 2016. The experiment was arranged in Completely Randomized Design (CRD) factorial, with three blocks as replications. The first factor was potato cultivars, consisting of three cultivars, namely Granola Lembang, Granola Kembang, and Median. The second factor was the composition of planting media, consisting of four compositions, namely 100% rice husk charcoal, rice husk charcoal:biogas waste 1:1, rice husk charcoal:biogas waste 2:1, and rice husk charcoal:biogas waste 3:1. Data were analyzed using Analysis of Variant (ANOVA) at 95% of confidence levels, and continued with HSD-Tukey and correlation analysis. The results provide information that number of G0 seeds were generated per crop on each cultivar was effected by the interaction between planting media composition and potato cultivars. The best planting media composition for Granola Lembang was rice husk charcoal:biogas waste 3:1 as it multiplies the number of G0 seeds were produced each crop. Meanwhile, the best planting media composition for Granola Kembang was rice husk charcoal:biogas waste 2:1 as it multiplies the number of G0 seeds were produced each crop. The 100% of rice husk charcoal was ideal for Median as it multiplies the number of G0 seeds were produced each crop. Keyword: media of agregat hydrophonic, potato cultivars, G0 seeds.
