Abstract: 【Objective】 Different dosage of microbial agents on the yield and quality in the production of processing tomatoes in Xinjiang. 【Methods】 To investigate the application effect of microbial agent "Junlintianxia".The tomatoes were subjected to different doses of microbials agent at the seedling, early flowering, and fruiting stages through root dipping and drip irrigation. 【Results】 The application of microbial agent significantly enhanced the growth potential, stress tolerance, and yield of processing tomatoes. The field investigation demonstrated that the application of microbial agent treatment resulted in a significant increase in crop yield by 9.3% and economic benefits by RMB 440.7/667m², when compared to conventional management practices. Additionally, there was a reduction of 12.7% and 13.7% in fertilizer and pesticide usage respectively. 【Conclusion】 The application of microbial agent "Junlintianxia" in processing tomato fields can effectively enhance the quality and yield of tomatoes, thereby significantly augmenting the economic benefits associated with processing tomatoes.
