| Abstract | The objectives of this study were (1) to explore the potential of the rhizo-product Bacillus cereus strain RS87[hereafter, "product"] in combination with different fertilizer regimes for enhancing rice tolerance to water stress while stillmaintaining good yield components, and (2) to examine the antioxidant defense system during water stress conditions. Resultsshowed that rice treated with the product with at least 75% recommended fertilizer rate (RFR) tolerated water stress well and hadmean total filled grain weight equivalent to rice growing naturally and receiving RFR alone. Meanwhile, water-stressed ricetreated with RFR alone had mean total filled grain weight about 30% less than non-stressed rice with the same amount offertilizer. In addition, two enzymatic components, SOD and PO activities, were significantly enhanced in rice treated with theproduct before and after water stress conditions compared to rice receiving RFR alone. |
