. Widawati, S, Sudiana, IM, Sukara, E, and Muharam, A 2012. The Technology of Tomato Plant Cultivation Through Inverted and Conventional Gardening Based on Utilization of Indigenous Bacteria. Azzofor-wd3 is a solid inoculant consisted of 16 peat indigenous bacteria isolates i.e. Rhizobium, Azotobacter, Azospirillum, and PSB four isolates respectively were used as biofertilizers to stimulate tomato production on inverted and conventional gardening. An experiment was conducted at the Research Center for Biology, Indonesian Institute of Sciences from January until December 2011. The research was aimed to determine the potential role of Azzofor-wd3 solid inoculant as a plant growth promoter in extremely environmental conditions. The treatments of growth media mixture were arranged in a completely randomized design with three replications. The based media was peat for 50% of mixture. The treatments were the addition of biofertilizers with the same volume of the based media (50%). The treatments were (1) peat only as the control, (2) chicken dunk, (3) compost, (4) fine sand, (5) lime, (6) Azzofor-wd3 inoculant, (7) chicken dunk + fine sand, (8) chicken dunk + lime, (9) chicken dunk + Azzofor-wd3, (10) compost + fine sand, (11) compost + lime, (12) compost + Azzofor-wd3, (13) fine sand + lime, (14) fine sand + Azzofor-wd3, (15) lime + Azzofor-wd3, (16) chicken dunk + compost + fine sand, (17) chicken dunk + compost + lime, (18) chicken dunk + compost + Azzofor-wd3, (19) chicken dunk + fine sand + lime, (20) chicken dunk + fine sand + Azzofor-wd3, (21) chicken dunk + lime + Azzofor-wd3, (22) compost + fine sand + lime, (23) compost + lime + Azzofor-wd3, (24) fine sand + lime + Azzofor-wd3, (25) Chicken dunk + compost + fine sand, (26) chicken dunk + compost + fine sand + Azzofor-wd3, (27) compost + fine sand + lime + Azzofor-wd3, and (28) chicken dunk + compost + fine sand + lime + Azzofor-wd3. The results showed that the highest production of tomato in inverted gardening was 63.9 g/pot and in conventional gardening was 65.9 g/pot produced by the plants grown on peat + chicken dunk + compost + sand + lime + Azzofor wd3 inoculant, 3 months after planting. There was significant difference of available-P, bacterial population, and PME-ase activity in inverted and conventional gardening before and after fertilization, whereas there was no significant difference of tomato yield between inverted and convensional gardening. It can be concluded that Azzofor-wd3 is potential as a plant growth promoting bacteria for tomato plants grown in peat soil. The application of the bacteria is very helpful to enrich peat soil for growing vegetable crops
