摘要： Application of bio-waste from agricultural industries like bagasse ash (BA) and biogas slurry (BGS) may improve soil physico-chemical properties like soil pH and nutrient bioavailability. This approach is more useful to deal with organic wastes. Two independent experiments were conducted to evaluate the impact of bioenergy wastes (BA and BGS) application, on phosphorus (P) uptake by wheat and maize. Eleven different treatments of BA and BGS in combination with rock phosphorus (RP) and diammonium phosphorus (DAP) were employed following completely randomized design with three replicates. Application of bio-wastes in combination with P fertilizers significantly improved growth and yield. Maximum grain yield in wheat was observed in treatment RP plus BA@ 10 Mg ha-1 (T9), while in maize, grain yield was maximum in treatment RP 75% plus BGS @ 0.6 Mg ha-1 (T10). Yield was correlated well with the P concentration in grains as maximum P concentration and contents were observed in same treatments having maximum grain yield i.e. T9 & T10, respectively. Both crops differed significantly to applied rock P and the bio wastes which is clearly indicated from the normalized values for grain yield and other parameters. Rock phosphate application is more suitable with bagasse ash for wheat (C3 plants) while for maize crop (C4 plants), rock P application is more suitable with biogas slurry with 75% dose of rock P. It is concluded that the efficient use of organic wastes is to apply with rock phosphate. This approach is also helpful in dealing with organic wastes like biogas slurry and bagasse ash in a sustainable manner.
