Abstract :Field experiments were carried out in a high tunnel strawberry field in Sultanhisar town of Aydin province during 2004 - 2005 cropping season. Plot size was 4.5 X 40 m for each character. Organic amendments used including winter growing broad bean, cabbage, cauliflower, broccoli and wild turnip plants were incorporated into soil by harrowing and sulfur dust was also applied at two different levels, 500 kg ha-1insert ignore into journalissuearticles values(sulfur I); and 1000 kg ha-1 insert ignore into journalissuearticles values(sulfur II);. Six-week soil solarization was applied to all plots after preparing planting beds. Following solarization, strawberry seedlings insert ignore into journalissuearticles values(cv. Camarosa); were planted at the first week of August. For bacterial treatments, strawberry seedlings were dipped into the bacterial suspension insert ignore into journalissuearticles values(108 cell ml-1); of Serratia plymuthica insert ignore into journalissuearticles values(HRO-C48); and fluorescent Pseudomonas insert ignore into journalissuearticles values(4K1); isolates before planting. One month later bacterial treatments were reapplied by drenching 10 milliliter of the same bacterial suspensions into soil around each plant. There was significant difference among the treatments and, the highest yield insert ignore into journalissuearticles values(46820 kg ha-1); was obtained from broad bean treatments. Other treatments resulted in the following yield values; broccoli 46300 kg ha-1, cauliflower 45370 kg ha-1, cabbage 43680 kg ha-1, only soil solarization 42980 kg ha-1, 4K1 41700 kg ha-1, radish 41190 kg ha-1, HRO-C48 39720 kg ha-1 sulfur I 34560 kg ha-1, and sulfur II 31800 kg ha-1. The lowest percentage of dead strawberry plants was observed with solarization only plots insert ignore into journalissuearticles values(26%);. This was followed by broad bean insert ignore into journalissuearticles values(27.7%);, broccoli insert ignore into journalissuearticles values(31.3%);, cauliflower insert ignore into journalissuearticles values(32%);, cabbage insert ignore into journalissuearticles values(35.3%);, HRO-C48 insert ignore into journalissuearticles values(36.7%);, radish insert ignore into journalissuearticles values(38.6%);, 4K1 insert ignore into journalissuearticles values(43.5%);, sulfur II insert ignore into journalissuearticles values(52.6%); and sulfur I insert ignore into journalissuearticles values(56.2%); treatments
