Abstract/ Executive Summary:

A field experiment was conducted at the multilocation testing (MLT) site, On Farm Research Division, BARI, Jhikargacha, Jessore under (AEZ-11) during rabi seasons 2008-09 and 2009-10 to investigate the effect of urea super granule (USG) on the growth and yield of potato. The experiment was laid out in RCB design with six dispersed replications with the unit plot size 5 m x 4 m. Five treatments were the same in two rabi seasons. viz. T₁ = Recommended dose of nitrogen as prilled urea (PU), T₂ = Recommended dose of nitrogen as urea super granule (USG), T₃ = 10% less of recommended dose of nitrogen as USG, T₄ = 20% less of recommended dose of nitrogen as USG and T₅ = Farmers practice (average of 20 farmers N dose used as PU). Significant variation was observed in different treatments. The highest yield of potato 33.21 t/ha were obtained from the recommended N dose of USG followed by USG 10% less than recommended dose of N (31.51 t/ha) during 2008-09. In the year 2009-10 higher yield was obtained from the T₂ treatment (32.33 t/ha) followed by T₃ (30.87 t/ha). By reducing 10% N losts through USG application more or equal returns can be obtained over prilled urea application. Cost and return analysis revealed that the treatment T₂ was obtained higher gross returns as well as BCR (2.74) followed by T₃ treatment (2.64).

Keywords: USG, Yield, Potato

Location: Farmer's Field of multiplication testing (MLT) site, Jhikargacha, Jessore

Start Date: 00-00-2008

End Date: 00-00-2010

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

To evaluate the efficiency of USG on the yield of potato
To find out the optimum and economic cost analysis in potato production

Methodology:

The experiment was carried out in the medium high land of AEZ 11 (High Ganges River Flood pain) at multiplication testing (MLT) site, Jhikargacha, Jessore during the two consecutive years in rabi season of 2008-9 and 2009-2010. The soil was analyzed for different properties before the start the experiment from SRDI, Jenaidha. The experiment was laid out in RCB design with six dispersed replications with the unit plot size 5 m x 4 m. Treatments were Five treatments were the same in two rabi seasons. viz. T₁ = Recommended dose of nitrogen as prilled urea (PU), T₂ = Recommended dose of nitrogen as urea super granule (USG), T₃ = 10% less of recommended dose of nitrogen as USG, T₄ = 20% less of recommended dose of nitrogen as USG and T₅ = Farmers practice (average of 20 farmers N dose used as PU). The recommended dose of nitrogen was 190 kg/ha. Other fertilizers were used as per recommended dose @ 20-110-15-4-1 kg PKSZn and B/ha in the form of triple super phosphate, murate of potash, gypsum, zinc sulphate and boric acid, respectively. Half of murate of potash was applied at 15 days after planting (DAP) and remaining half at 30 DAT. USG was applied at 15 DAT as ring method, 9-10 cm apart from plant stalk and 7-8 cm depth covering with soil. Potato was planted in 2 December, 2008 and 25 November 2009 and harvested in 4 March 2009 and 10 March 2010 respectively. The collected data were analyzed statistically following the ANOVA technique with the help of MSTA-C software package and means were separated by DMRT at 5% level of significance. Cost and return of all inputs and outputs were noted down and economic analysis of different treatments was done for benefit cost ratio (BCR). Gross return was calculated from two years mean yield of potato.

Achievement/Findings:

On the basis of two years results, it can be concluded that yield and income might be increased through using USG, on an average 10% use N application as USG which can be saved on compared among the treatments. So, the increased price of N fertilizer and the nation can save 10% fertilizer in potato production.
