The Effect of Liquid Seaweed of Organic Origin on Seed Germination and Seedling Development of Some Winter Cereal Species

Abstract

In this study, the effects of liquid seaweed on seed germination and seedling growth in some winter cereal species (triticale, barley, and wheat) were investigated. In the study, 6 different doses (D0: tap water D1:1000 ppm L-1, D2:2000 ppm L-1, D3:4000 ppm L-1, D4:8000 ppm L-1, D5:16000 ppm L-1) of seaweed were used. The experiment was conducted according to the split-plot trial design in random plots with 3 replications. Germination rate (%), radicle plumule and seedling length (cm), seedling fresh weight (g), seedling dry weight (g), and seedling vigor index were measured during the 14-day development period of cereal species at all seaweed doses. According to the study findings, except for germination rate in the cereal species; significant differences were found between the mean values of all the properties examined in the cereal types, fertilizer doses, and species x dose interactions. Wheat among cereals had the highest values regarding radicula length, seedling vigor index, seedling dry weight, plumule length, and seedling length. D2 dose from the doses of seaweed fertilizer form; germination rate, seedling vigor index, seedling dry weight, seedling fresh weight, plumule length, and seedling length were found to have the highest values, while D5 dose was the lowest. In terms of species x dose interaction, Germination rate, radicle length, seedling vigor index, and seedling length were found to be high in TxD1 interaction. Germination rate was found to be high in HxD0 interaction. Germination rate, radicle length, seedling vigor index, and seedling dry weight were found to be high in WxD2 interaction. As a result, in the germination study with liquid seaweed, D2 doses for wheat, D1 and D2 doses for triticale, D0, D1, and D2 doses for barley were found as encouraging.
