ABSTRACT
An experiment was conducted with a view to observe the efficiency of Urea Super Granule (USG) on tomato. The variety, Ratan was tested in the farmer`s field at FSRD site, Syedpur, Rangpur under Tista Meander Floodplain highland soils (AEZ No. 3) for two consecutive years during Rabi, 2001-02 and 2002-03. The experiment was laid out in RCB design with six dispersed replications. Two forms of urea i.e. prilled urea (PU) and USG with different rates were used. The two years` results revealed that urea super granule had significant positive effect on the yield of tomato as compare to normal urea. The recommended dose of N (150 kg ha-1) from USG gave the significantly highest marketable fruit yield of 79.13 t ha-1 in 1st and 73.60 t ha-1 in 2nd year. It was also possible to harvest marketable fruit of 73.69 t ha-1 in 1st and 68.29 t ha-1 in 2nd year and 68.13 t ha-1 in 1st and 62.45 t ha-1 in 2nd year using 90% (135 kg ha-1) and 80% (120 kg ha-1) recommended dose of N from USG and these yields were statistically identical to the yield (67.22 t ha-1 in 1st and 60.23 t ha-1 in 2nd year) obtained from 150 kg ha-1 N from prilled urea. The 150 and 135 kg ha-1 of N from USG gave 11 and 2% higher yield of tomato than that of using 150 kg ha-1 N from prilled urea, respectively. These results implied that efficiency of USG was found to be positive on the yield of tomato and 20% N might be saved using USG compare to PU. The economic analysis also showed that the use of urea super granule was economically viable to cultivate the tomato. Farmers show their willingness to use USG.
