Tomat (Lycopersicum esculentum Mill.) merupakan salah satu jenis sayuran yang banyak dibudidayakan oleh petani baik di dataran tinggi maupun rendah, karena mempunyai prospek yang baik untuk diusahakan secara komersial dalam bentuk buah segar atau hasil pengolahan. Tomat dapat ditanam di dataran rendah maupun dataran tinggi dan tomat selain sayuran juga dikatakan buah karna kaya akan vitamin dan mineral. Penggunaan buahnya semakin luas, karena selain dikonsumsi sebagai tomat segar dan bumbu masakan, dapat diolah sebagai bahan baku industri makanan seperti sari buah dan saus tomat. Rendahnya produktivitas tanaman tomat Chery sering dihadapkan berbagai masalah dalam budidayanya terutama masalah hama dan penyakit. Upaya yang dapat dilakukan untuk meningkatkan produktifitas hasil budidaya tanaman tomat ialah dengan menggunakan Plant Growth Promoting Rizobacteri (PGPR). Penelitian ini bertujuan untuk mengetahui pengaruh rizobakteri isolat Indigenous terhadap pertumbuhan dan hasil tanaman tomat Chery. Penelitian ini dilaksanakan di Kebun Percobaan 1 Fakultas Pertanian dan Laboratorium Ilmu dan Teknologi Benih Universitas Syiah Kuala. Penelitian dimulai pada bulan Juli sampai dengan September 2022. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) pola non faktorial dengan 8 perlakuan dan 3 ulangan, sehingga terdapat 24 kombinasi perlakuan. Apabila hasil uji F menunjukkan pengaruh yang nyata, maka analisis diteruskan dengan uji Beda Nyata Terkecil dengan taraf 5%. Parameter yang diamati yaitu tinggi tanaman, diameter batang, berat buah per tanaman, diameter buah, jumlah buah per tanaman dan potensi hasil. Hasil penelitian menunjukkan bahwa perlakuan Rizobakteri isolat Indigenous berpengaruh sangat nyata terhadap tinggi tanaman tomat 15 HST, berat buah per tanaman, diameter buah, jumlah buah pertanaman dan potensi hasil tanaman tomat. Berpengaruh nyata pada tinggi tanaman tomat 30 dan 45 HST dan diameter batang. Perlakuan terbaik pada parameter tinggi tanaman, diameter batang tomat, berat buah per tanaman, diameter buah dan potensi hasil adalah perlakuan LDG 7/3.

Tomato (Lycopersicum esculentum Mill.) is a type of vegetable that is widely cultivated by farmers both in the highlands and lowlands, because it has good prospects for commercial cultivation in the form of fresh fruit or processed products. Tomatoes can be grown in the lowlands and highlands and tomatoes besides vegetables are also said to be fruit because they are rich in vitamins and minerals. The use of the fruit is increasingly widespread, because apart from being consumed as fresh tomatoes and cooking spices, it can be processed as a raw material for the food industry such as fruit juice and tomato sauce. The low productivity of the Chery tomato plant is often faced with various problems in its cultivation, especially pest and disease problems. Efforts that can be made to increase the productivity of tomato cultivation is to use Plant Growth Promoting Rizobacteri (PGPR). This study aims to determine the effect of Indigenous rhizobacteria isolates on the growth and yield of Chery tomato plants. This research was conducted at the Experimental Garden 1 of the Faculty of Agriculture and the Laboratory of Seed Science and Technology, University of Syiah Kuala. The study began from July to September 2022. This study used a non-factorial Randomized Block Design (RBD) with 8 treatments and 3 replications, so there were 24 treatment combinations. If the results of the F test show a significant effect, then the analysis is continued with the Least Significant Difference test with a level of 5%. Parameters observed were plant height, stem diameter, fruit weight per plant, fruit diameter, number of fruit per plant and yield potential. The results showed that the treatment of Indigenous Rhizobakteri isolates had a very significant effect on tomato plant height at 15 HST, fruit weight per plant, fruit diameter, number of fruit planted and yield potential of tomato plants. Significant effect on tomato plant height 30 and 45 DAP and stem diameter. The best treatment on the parameters of plant height, tomato stem diameter, fruit weight per plant, fruit diameter and yield potential was LDG 7/3 treatment.
