APLIKASI PERBANDINGAN JENIS MEDIA TANAM DAN KONSENTRASI PUPUK CAIR Plant Growth Promoting Rhizobacteria (PGPR) TERHADAP PERTUMBUHAN DAN HASIL TANAMAN TOMAT (Lycopersicum esculentum Mill)

Abstract

application of comparison of types of planting media and liquid fertilizer concentrations of Plant Growth Promoting Rhizobacteria (PGPR) on the growth and yield of tomato plants (Lycopersicum esculentum Mill) Agriculture,Abulyatama University, Jln. Sultan Iskandar Muda Airport, Blang Bintang District, Aceh Besar District, Aceh August to November 2022. The materials used in this study were tomato seeds, husk charcoal, rice husks, coffee grounds, cow dung, and PGPR liquid fertilizer, as well as other materials. . The materials used in this study were polybags, hoes, buckets, plastic straps, analytical scales, research marks, cameras, and stationery. The design used in this study was a randomized block design (RAK) with a 4 x 4 factorial cropping pattern, each pattern was repeated 3 (three) times and in 48 experimental units the type of planting media had a very significant effect on the plants. . height and number of fruit heads, but no significant effect on the best stem diameter. growing media. M2 plant height (2 soil : 1 manure : 1 husk charcoal, and the best number of fruit seeds on M2 (2 soil : 1 manure : 1 rice  soil : 1 manure : 1 husk) ) ) and at high PGPR concentrations the best plants were found in G2 (10 ml/1 water), the best number of fruits were found in G2 (10 ml/1 water) and G3 (15 ml/1 water). there was no interaction between the type of growing media and PGPR concentration on plant height, number of fruits per bunch and stem diameter.
