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

Abstrak

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. The study was carried out between November 2023 and February 2024. The research site at Green House is owned by the Faculty of Agriculture, PGRI University of Yogyakarta. 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 data was evaluated using a real-scale analysis of variance and Duncan's multiple range test at a significant level of 5%. 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.
