Respon Pertumbuhan Bibit Tanaman Jambu Biji 'Kristal' (Psidium guajava L.) pada Dua Jenis Media Tanam dan Beberapa Jenis Mikroorganisme Lokal (MOL) Limbah Pertanian

Abstract

This study aims to determine the effect of various planting media and local microorganisms on the growth of 'Kristal' guava seedlings and the interaction between the provision of various planting media and local microorganisms on the growth of 'Kristal' guava seedlings. This research was conducted at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung from August 2020 to March 2021. The treatments were arranged in a factorial (2x4) in a completely randomized design (CRD) which was repeated 3 times. The first factor was planting media (M) which consisted of (M1) soil and rice husks, (M2) soil and mushroom baglog. The second factor is types of local microorganisms (MOL) (P) which consists of 4 levels, namely (P1) local microorganisms EM4, (P2) local microorganisms of stale rice, (P3) local microorganisms of oil palm empty fruit bunches, and (P4) local microorganisms of fruit and vegetables. rotten vegetables. The results of research that have been processed by analysis of variance on all observational variables state that the provision of different planting media affects the observation variables, namely the number of leaves, number of shoots, stem diameter of 200 mm from grafting eye, dry weight of the trunk, leaf area and content of chlorophyll content but not significantly different in plant height while the treatment of different local microorganisms as well as the interaction of the treatment of various planting media and local microorganisms did not show a significant effect on all existing observation variables.Keywords : Guava, growing media, local microorganisms, growth
