This experiment was conducted to evaluate the overall performance of urea application methods in the farmers’ field at Gosaidanga in Shailkupa upazila under Jhenaidah district and at Rashidpur in Mithapukur upazila under Rangpur district during boro (2015) season. Three treatments i.e. T1 = Hand broadcasting of urea (recommended dose) (HB), T2 = BRRI prilled urea applicator (70% of the recommended dose) (PUA) and T3 = BRRI USG applicator (70% of the recommended dose) (USGA) were used in the experiment. The experiment was laid out in randomized complete block design (RCBD) and replicated in four farmers’ plot.  The field capacity of the PUA and USGA obtained similar  i.e. 0.09-0.10 ha/hr in both locationsPUA and USGA saved 29-32 percent urea fertilizer compared to HB. Grain yield showed significantly similar in PUA, USGA and HB. Only urea fertilizer cost varied and other input cost in the form of labor and material obtained similar in all urea application plot. PUA and USGA reduced 2-2.5% input cost than HB in crop cultivation. BRRI prilled urea applicator and BRRI USG applicator safely dispensed urea fertilizer in subsurface, deep placement increase the efficacy of urea fertilizer and save huge amount of urea fertilizer without sacrificing grain yield.

·        1. To estimate the savings of urea fertilizer

·        2. To evaluate the field performance of prilled urea applicator

·         3.To estimate the yield and yield contributing character

·         4.To compare the cost of prilled urea applicator over traditional method

Experimental location: This experiment was conducted in the farmers’ field at Gosaidanga in Shailkupa upazila under Jhenidah district and at Rashidpur in Mithapukur upazila under Rangpur district. Experimental design: The experiment was carried out in randomized complete block design (RCBD) and replicated in four farmers’ plots. Twelve plots within one kilometer radius were selected to conduct this study.  Treatment :T1 = Hand broadcasting of urea (recommended dose) (HB);  T2 = BRRI prilled urea applicator (70% of the recommended dose) (PUA) and T3 = BRRI USG applicator (70% of the recommended dose) (USGA). Fertilizer rate was different and all other inputs were similar in three methods. Data on labour requirement, field capacity, amount of nitrogen fertilizer  use, tillering dynamics, yield and yield contributing characters were taken and analysed using software Statistix 9.0. Least significant difference was used to compare the means. In order to estimate the production cost, the data on working speed, total time and labor involvement and materials inputs to complete the operation were recorded. Rental charge of the machines was also included in the cost estimation. Land rental value and interest on investment were considered to calculate the total input cost. Price of the produce was collected from the local markets to compute total production cost, gross return, gross margin and benefit-cost ratio.

Urea applications gave significant effect on grain yield. Prilled urea application method produced higher grain yield than other urea application methods. It reduced the production cost. Finally, it can be concluded that among the nitrogen management options, PUA and USGA saved 29-32% of prilled urea without sacrificing grain yield.
