The response of rice plant to phosphate¬ dissolving bacteria and azolla under two phosphorus fertilization rates

Abstract: Two field experiments were carried out at Sakha Agric. Res. Station during two successive seasons 2002/2003 to study the effect of two sources of bio-fertilizers (phosphate dissolving bacteria Bacillus megatlzerium and Azolla) under two sources of chemical P fertilizer (as superphosphate or rock phosphate). It was found that both bio-fertilizers compared with control caused an increase in grain and straw yield of rice and macronutrients content (N,P and K) in grain at harvest stage as well as protein and total carbohydrate in grain of rice. Biofertilization under chemical P fertilizer was more effective than chemical P-fertilizer only. P-fertilizer superphosphate (SP) superiored rock phosphate fertilizer The present study recommended using of PDB plus Azolla with application of rock phosphate at rate of 150 kg/fed to obtain the highest rice grain yield with good quality
