VIABILITAS DAN VIGOR BERBAGAI VARIETAS TRUE SHALLOT SEED DENGAN PERENDAMAN JENIS ZAT PENGATUR TUMBUH (ZPT) ALAMI

One of the keys to successful shallot cultivation with True Seed Shallot (TSS) is determined by viability and vigor at nursery. The aim study was determine effect varieties types natural Plant Growth Regulatory (PGR) on germination TSS index. conducted Technology Laboratory Agricultural Development Polytechnic Yogyakarta Magelang in July 2021 using a factorial Completely Randomized Design (CRD). first factor variety (V) consisting 3 levels: V1 = Sanren, V2 Maserati, V3 Lokananta. second Types Natural plant Regulators (Z) 4 types: Z0 aquadest, Z1 Extract, Z2 bean sprout extract, Z3 young coconut water. Each treatment repeated times. Parameters observed were germination, growth speed Data analysis carried out variance test (F test) Duncan's multiple distance (DMRT) level 0.05. results showed that significantly affected speed. type PGR did not affect but it interacted index parameter. best achieved when Lokananta treated distilled Keywords: Shallot, sprouts, water, vigor.
