Abstract
A field experiment was carried out at the field laboratory of Department of Agronomy, Patuakhali Science and Technology University, Dumki, during the period from March 2015 to August 2015 to assess the comparative advantages of using Urea Super Granule (USG) and NPK briquette over normal urea and also predict the better performing transplanted Aus rice in the tidal ecosystem. The effect of different levels of fertilizer was studied on growth, yield and yield attributing character of transplanted Aus rice. Five fertilizer treatments (N 1 = Recommended doses of all fertilizers, N 2 = Urea super granule at 112.5 kg/during 10 DAT at available tide free time, N 3 = NPK briquette at 150 kg haG 1 during 14 DAT at available tide free time, N 4 = Nitrogen control, N 5 = Absolute control) with four HYV Aus rice varieties (V 1 = BRRIdhan27, V 2 = BRRIdhan48, V 3 = BRRIdhan55 and V 4 = BRRIdhan65). The experiment was laid out in a split plot design with 3 replications. The analysis revealed that different fertilizer management practices with a few exceptions significantly influenced the growth, yield and yield attributes of the transplanted Aus rice varieties. Plant height, number of effective tillers per hill, panicle length (cm), number of grains panicle-1, nitrogen use efficiency (%), straw yield (t haG 1 ) and grain yield (t haG 1 ) were found highest when USG was applied with BRRIdhan48 and all the characters showed lowest value when absolute control with BRRIdhan55. Highest number of effective tillers per hill (11.15) and grain yield (3.33 t haG 1 ) was obtained from USG and BRRIdhan48 and where lowest number of effective tillers per hill (9.21) and grain yield (2.28 t haG 1 ) in absolute control with BRRIdhan55. The NPK briquettes showed higher agronomic efficiency than Prilled Urea (PU) and Urea Super Granule (USG). The USG (1.8 g) and NPK briquettes (2.4 g) could save 11.3 and 19.55 kg N haG 1 compared to recommended PU. There was no residual effect of USG on soil chemical properties. The USG with BRRIdhan48 were found beneficial to the farmers in tidal ecosystem.
