EFEKTIVITAS EKSTRAK BAWANG MERAH (Allium ascolanicum L.) DENGAN PERIODE PERENDAMAN TERHADAP INVIGORASI BENIH KEDELAI (Glycine max L.)

This study was conducted to determine the effect of soaking soyabean seeds in shallot extract, a natural ZPT, on viability and seed growth. The research was conducted from August to October 2024 in the experimental garden of the Faculty of Agriculture, Barital Islamic University using a completely randomised design (CRD) with five treatments and four replications. The treatments were seed soaking in water for 1 hour and shallot extract for 2, 3, 4 and 5 hours. Parameters observed included growth vigour, growth rate, growth synchronisation, and vigour index. The results showed that soaking for 3 hours gave the best results on all variables.
