Pada penelitian ini bertujuan untuk mengetahui pengaruh berbagai jenis dan konsentrasi zat pengatur tumbuh (ZPT) terhadap pertumbuhan dan hasil dua kultivar tomat beef. Penanaman di Laboratorium Kultur Terkendali, Fakultas Pertanian, Universitas Padjadjaran dengan ketinggian ± 782 meter di atas permukaan laut (mdpl). Benih tomat yang digunakan yaitu kultivar "˜Valoasis', dan kultivar "˜Momotaro' sedangkan zat pengatur tumbuh (ZPT) yang digunakan yaitu giberelin (GA3), dan auksin (IAA). Pengamatan yang dilakukan terdiri atas tinggi tanaman, jumlah daun, jumlah bunga per tanaman, dan jumlah buah per tanaman. Hasil penelitian ini menunjukkan bahwa Momotaro + Giberelin 20 ppm + Auksin 20 ppm dan Valoasis + Kontrol memperoleh hasil terbaik pada pertumbuhan dan hasil dua genotipe tomat beef pada jenis dan konsentrasi ZPT berbeda.
