Increased growth and yield of cherry tomato, especially in the lowlands is influenced by the availability of water, humidity, and cultivation technology of plants, so it takes hydroponic system to realize the growth and yield enhancement of cherry tomato. This research aims to identify the proper concentration of nutrient on the growth and yield of cherry tomato with hydroponic system. This research was conducted at Screenhouse of Royal Sumatera Housing, Medan Tuntungan (± 32 meters above sea level), from March to August 2017. The research used Completely Randomized Design with one treatment factor that is nutrition concentration (1300 ppm,1750 ppm, and 2200 ppm). The results showed that the provision of real nutrient concentration increased the parameters of plant height, stem diameter at 7-8 weeks after planting move, plant flowering age, number of branches per plant, and number of segments per plant, but no significant effect although it tended to increase the number of fruit per plant and fruit weight per plant at nutrient concentration of 2200 ppm
Peningkatan pertumbuhan dan produksi tomat cherry khususnya di dataran rendah dipengaruhi oleh ketersediaan air, kelembaban, serta teknologi budidaya tanaman, sehingga diperlukan sistem hidroponik untuk mewujudkan peningkatan pertumbuhan dan produksi tomat cherry. Penelitian ini bertujuan untuk mengidentifikasi konsentrasi nutrisi yang tepat pada pertumbuhan dan produksi tomat cherry dengan sistem hidroponik. Penelitian ini dilaksanakan di Screenhouse Perumahan Royal Sumatera, Medan Tuntungan (± 32 m dpl), pada bulan Maret sampai dengan Agustus 2017. Penelitian menggunakan Rancangan Acak Lengkap dengan satu faktor perlakuan yaitu konsentrasi nutrisi (1300 ppm, 1750 ppm, dan 2200 ppm). Hasil penelitian menunjukkan bahwa pemberian konsentrasi nutrisi nyata meningkatkan parameter amatan tinggi tanaman, diameter batang pada umur 7-8 MSPT, umur berbunga tanaman, jumlah cabang per tanaman, dan jumlah ruas per tanaman, tetapi tidak berpengaruh nyata walaupun cenderung meningkatkan parameter jumlah buah per tanaman dan bobot buah per tanaman pada konsentrasi nutrisi 2200 ppm.
