Abstract:
Objective: Evaluation of new nutrient sources plays an important role in crop production. A field experimentwas conducted at BRRI, Gazipur and at BRRI regional station, Sonagazi, Feni during Boro season of 2014-15.A new fertilizer, NP compound (NPC) was evaluated and compared the performances with di-ammoniumphosphate (DAP). Test crop was BRRI dhan29. At Gazipur site, phosphorus (P) control plot produced only 1.97t ha-1 grain yield that increased with added P along with two N rates. At lower N doses, application of P eitherfrom DAP or NPC produced similar grain yield. It was observed that 30% less N produced statistically similargrain yield to 100% N, irrespective of P sources. It can be inferred that 30% N could be saved withoutsignificant reduction of rice yield. At Sonagazi site, application of P either from DAP or NPC could not increaserice grain yields compared to P control plot. From the results of both sites it can be concluded that NPC andDAP performed equally either with 100% N or 30% less N rates.
