PROFICIENCY AND PROFITABILITY OF POTATO AS AFFECTED BY UREA SUPER GRANULE (USG) AS A SOURCE OF NITROGEN IN HIGH GANGES RIVER FLOOD PLAIN OF BANGLADESH (Pages : 28 - 30)

A field experiment was conducted at the multilocation testing (MLT) site, On Farm Research Division, BARI, Jhikargacha, Jessore under High Ganges River Floodplain (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 5m x 4m. 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). Download
