Growth response of pepper (Piper nigrum L.) on application Arbuscular Mycorrhizal Fungi (AMF) and the shallot filtrate

Abstract

Abstract This study aimed to determine the effect of Arbuscular Mycorrhiza Fungi (AMF) and shallot filtrate on the growth of pepper plant. The study was conducted in the district of Tompobulu, Bantaeng Regency, South Sulawesi Province from November 2018 to March 2019. The trial was conducted in the form of two factors factorial experiment (F2F) based on randomized block design (RBD) with AMF as the first factor consisted of 4 levels: 0, 2, 4, and 6 g/polybag and shallot filtrate as second factor consisted of 4 levels of 0, 10, 20, 30%. The experimental results show that the interaction of AMF 2 g/polybag + 10% of shallot filtrate resulted in the highest average plant height (60.19 cm) at 18 weeks after planting. Treatment of AMF 6 g/polybag + shallot filtrate of 10% produced the highest chlorophyll b (390.41 μmol.m −2 ), total chlorophyll (818.64 μmol.m −2 ), and stomatal density (24.63 mm 2 ). Application of AMF 4 g/polybag + 30% of shallot filtrate resulted in the largest stomatal aperture area (26.28 mm 2 ). AMF 6 g resulted in the highest average of root length (31.17 cm) and percentage of root infected with mycorrhizal (7.82%).
