This research was held for 5 months (Juny-October) at Banjarsengon sub village, Gebang village, Patrang Jember with a height above 90 m asl. And conducted Randomized Block Design (RBD) with 2 factors and 3 replications. The first factor was a adheshive material consisted of without adhesive material, tapioca 5%, molasses 90%. Second factor was sheating material combination Arabic gum:gypsum consisted of (0:0), (0:100), (25:75), (50:50), (75:25), (100:0). The result showed that the adhesive material treatment has very significant effect on seed total each plant and significant for seed weight each plant, and potential each hectare. Adhesive material molasses 90% showed the best result on that parameter. Sheating treatment has significant effect on plant height at vegetatif, weight dry crown and root, fruit total each plant, germination capacity, germination quality, and seed germination speed, very significant effect on seed total each plant. Sheating treatment combination Arabic gum:gypsum 50:50 (G3) showed the best result on that parameter. There was interaction between adhesive material and sheating to the fruit total each plant, seed weight each plant, and potential each hectare. Adhesive material molasses 90% and sheating combination Arabic gum:gypsum 25:75 (P2G2) showed the best potential each hectare is 114,6 kg. Key words : Adhesive Material, Sheating, Rhizobium sp, Seed Tomatoes
