Effect of local microorganisms (LOM) and growing media on growth of guava (Psidium guajava L.) at nursery stage

Abstract

Guava is a fruit that trade internationally. One of the problems in Indonesia is preparing the plant for a seedling. This research investigated the effect of local microorganisms and growing media on Guava’s growth at the nursery stage. The experiment was conducted from June to August 2020, at the experimental site of agriculture faculty, University of Lampung. The design used was a Complete Randomized Design (CRD) with two factors: growing media and local microorganisms (LOM). Growing media consisting of 2 types, M1: combination soil and rice husk, M2: combination soil and baglog waste. Local microorganisms consisting of 4 types, P1: local microorganisms from EM4, P2: local microorganisms from rice fermentation, P3: local microorganisms from oil palm empty bunches fermentation, P3: local microorganisms from fruit and vegetable fermentation. The results showed that the treatment combination of local microorganismss and growing media did not show the dominant pattern. Growing media combination of soil and rice husk was better than a combination of soil and baglog waste to support Guava’s growth. Local microorganisms from fruit and vegetable fermentation promote the high value on the growth of Guava.
