استخدام البكتريـا Pseudomonas fluorescens كمخصب حيوي لتحسين نمو وإنتاجية نباتات الحنطة

Abstract

This study was conducted to evaluate the efficacy of two application methods, two timing inoculation and two preparation of Pseudomonas fluorescens (isolate PFW6) in increasing growth and productivity of wheat plant (C. V. Maxiback) in the field for two seasons (2000-2001, 2001-2002). The results revealed that the efficacy of seed treated with bacterial suspension caused increase in seed germination by 13 and 12.9% for the two seasons respectively. Further more, 3 days earliness in germination was noticed in comparison with the control. Also results showed that seed treatment with dry powder formulation of biofertilizer caused increasing in total yields of 36.7% (1030 Kg/Donum). More over seed and soil treatments with bacterial suspension revealed an increasing in the total yields which was 34.2% (1011.9 Kg/Donum) and 33.8% (1003.75 Kg/Donum) respectively compared with the control (753.75 Kg/Donem).
