Effect of Planting Media Composition and Arbuscular Mycorrhizal Fungi (AMF) on Growth and Root Infection of Potato Seed G0 Granola Cultivars

Abstract

G0 potato seed production in Indonesia is still deficient and continues to decline. The use of compost and husk charcoal as planting media and Arbuscular Mycorrhizal Fungi (AMF) aims to help the growth and yield of G0 potato seedlings. This experiment was conducted from April to June 2020 in Cikajang, Garut, West Java province. This experiment was conducted with two treatment factors using Randomize Block Design (RBD) factorial pattern 4x4, two replications. There are 4 levels of planting media composition (t1= compost (control), t2= compost and husk charcoal (1:1), t3= compost and husk charcoal (2:1), t4= compost and husk charcoal (3:1)) . There are 4 levels of AMF (m1= 0 g/Plot (control), m2= 150 g/Plot, m3= 300 g/Plot, m4= 450 g/Plot). The experimental results showed that the composition of the growing media independently showed no significant difference in all observation parameters. The AMF showed significant differences in the observed parameters of plant height 30 DAP, several leaves 30 and 60 DAP, stem diameter 45 DAP, root length 80 DAP, and infection 85 DAP. The best factor in this experiment was m4 = 450 g/plot on the observation parameters of plant height, number of leaves, stem diameter, root length, and root infection.
