Response of mustard to the application method of prilled urea and urea supper granule
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2012, Vol 3, Issue 12
Abstract
The field experiment was conducted at the Agronomy field of Sher-e-Bangla Agricultural University, Dhaka during Rabi season (October- February) 2009-2010 to study the influence of application method of prilled urea and urea suppergranule on yield of mustard. The treatments comprised of T1= Prilled Urea (PU) broadcasted (conventional method), T2=PU given in the side furrows, T3= PU given between two rows, T4=PU and seed given in the same furrows, T5=Urea Super Granules (USG) placed at 5 cm depth as basal, T6=USG placed at 5 cm depth at 10 days after sowing (DAS), T7=USG placed at 5 cm depth at 20 DAS, T8=USG placed at 5 cm depth at 30 DAS, T9=USG placed at 10 cm depth as basal, T10=USG placed at 10 cm depth at 10 DAS, T11=USG placed at 10 cm depth at 20 DAS, T12=USG placed at 10 cm depth at 30 DAS, T13=USG placed at 15 cm depth as basal, T14=USG placed at 15 cm depth at 10 DAS, T15=USG placed at 15 cm depth at 20 DAS and T16=USG placed at 15 cm depth at 30 DAS. Results showed that USG placed at 5 cm depth at 20 DAS gave the highest branches plant-1 (6.86), siliquae plant-1 (58.60), seeds siliqua-1 (32.00), 1000 grain weight (3.56 g) which reflected in higher values of seed yield (3.59 t ha-1), biological yield (6.78 t ha-1) and harvest index (52.62%) compared to PU application. Use of USG had two fold advantages over conventional use of PU. It out yielded PU by 39.14% when this method required about 52.38% less urea than the amount of PU was used.
