Respon Pertumbuhan Dan Hasil Tanaman Tomat (Lycopersicum Esculentum) Dengan Aplikasi PGPR

Abstract

Vegetables like tomatoes are in high demand, grow in value annually, and are significant to the Indonesian economy. This study aims to determine the optimal PGPR type and its impact on tomato crop growth and yield. This research method used a completely randomized design in three replications using multiple kinds of PGPR consisting of five levels: control, PGPR bamboo roots, PGPR sensitive plant roots, PGPR teakwood roots, and PGPR corn roots. The variables observed were plant height, stem diameter, number of leaves, fruit number, weight, and diameter. The result showed that the treatment of PGPR significantly affected plant height, stem diameter, number of leaves, fruit number, weight, and diameter. The PGPR with sensitive plant root types had the best treatment for tomato growth and yield.
