Tomat digemari karena memiliki kandungan gizi yang tinggi dan dapat diolah menjadi berbagai jenis olahan makanan. Budidaya tomat saat ini terbatas dikarenakan semakin berkurangnya lahan pertanian. Upaya yang dapat dilakukan adalah dengan memanfaatkan lahan marginal pasir pantai. Namun, lahan pasir pantai memiliki faktor pembatas, seperti adanya salinitas yang dapat mengganggu pertumbuhan tanaman. Tujuan penelitian ini adalah mengetahui tingkat pertumbuhan dan hasil tanaman tomat terbaik diantara cara pemberian larutan salin, konsentrasi larutan salin, dan frekuensi pemberian larutan salin, serta menjelaskan interaksi antara cara pemberian, konsentrasi, dan frekuensi pemberian larutan salin terhadap pertumbuhan dan hasil tanaman tomat. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) yang terdiri atas 3 faktor. Faktor pertama adalah cara pemberian larutan salin (melalui tanah dan melalui daun). Faktor kedua adalah konsentrasi larutan salin (0 dS/m, 9 dS/m, 18 dS/m). Faktor ketiga adalah frekuensi pemberian larutan salin (1 kali/hari, 2 kali/hari, 3 kali/hari). Data hasil pengamatan diamati dengan sidik ragam dan dilakukan uji Duncan’s Multiple Range Test (DMRT) 5%. Hasil penelitian menunjukkan bahwa cara pemberian larutan salin melalui tanah memberikan respon lebih baik terhadap luas daun (1925,87 cm2), jumlah cabang (27,41 buah), bobot segar daun (50,68 g), dan persentase bunga jadi (39,05%). Peningkatan konsentrasi dan frekuensi pemberian larutan salin menurunkan pertumbuhan dan hasil tanaman tomat. Konsentrasi 0 dS/m menunjukkan luas daun (2.234,20 cm2), bobot kering tanaman (45,42 g), dan produktivitas tanaman (11,78 t/ha) terbaik. Frekuensi 1 kali/hari menunjukkan luas daun (2.081,84 cm2), jumlah cabang (28,33 cabang), dan diameter buah (2,89 cm) terbaik.

Tomatoes are popular because have a high nutritional content and can be processed into various types of foods. Tomato cultivation is currently limited due to the decreasing number of agricultural land. Efforts that can be made to deal with these obstacles are utilizing marginal land of coastal sand. Coastal island has limiting factors in utilization, one of which is there salinity levels that can interfere with plant growth. The purpose of this research is was to determine the best rate of growth and yield of tomato plants among the methods of administration of saline solution, concentration of saline solution, and frequency of administration of saline solution, and to explain the interaction between the method of administration, concentration, and frequency of administration of saline solution on the growth and yield of tomato plants. This study was conducted using a completely randomized block design (RAKL) which consisted of 3 factors. The first factor is the way of distributing the saline solution (through the soil and through the leaves). The second factor is the concentration of the saline solution (0 dS/m, 9 dS/m, 18 dS/m). The third factor is the frequency of distributing of saline solution (1 time/day, 2 times/day, 3 times/day). The result of the observation data were observed by means of variance and the Duncan’s Multiple Range Test (DMRT) 5% test was performed. The results showed that the method way of distributing saline solution through the soil gave a better response to leaf area (1925,87 cm2), number of branches (27,41 brances), leaf raw weight (50,68 g), and fruit set (39,05%). Increasing the concentration and frequency of saline solution decreased the growth and yield of tomato plants. Concentration of 0 dS/m showed the best leaf area (2234,20 cm2), plant dry weight (45,42 g), and productivity (11,78 t/ha). The frequency of 1 time/day showed the best leaf area (2081,84 cm2), number of branches (28,33 branches), and fruit diameter (2,89 cm).
