Abstract/ Executive Summary:

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 experimental treatments included two forms of urea viz. prilled urea (PU) and urea super granules (USG) at the rate of 300 kg ha^-1 and 142.86 kg ha^-1 (2.7 g per USG) and there were eleven treatment combinations, respectively. 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.

Location: Agronomy field of Sher-e-Bangla Agricultural University, Dhaka

Start Date: 00-10-2009

End Date: 00-02-2010

Program Area: Crop-Soil-Water Management

Commodity: Mustard, Fertilizer

Objectives:

To study the influence of application method of prilled urea and urea suppergranule on yield of mustard

Methodology:

The field experiment was conducted at the Agronomy field, Sher-e-Bangla Agricultural University (SAU), under the agro-ecological zone of Modhupur Tract, AEZ-28, during rabi season (October, 2009 to February, 2010) with a view to investigate the influence of application methods of prilled urea and urea supergranules on yield of mustard. The farm belongs to the Shallow Red Brown Terrace Soils under Tejgaon Series. The soil texture was silty-loam. The soil was low in organic matter and nitrogen in content. The experiment was laid out in a Randomized Complete Block Design (RCBD) design with three replications. BARIsharisha-14 was used as a test crop. The experimental treatments included two forms of urea viz. prilled urea (PU) and urea super granules (USG) at the rate of 300 kg ha^-1 and 142.86 kg ha^-1 (2.7 g per USG), respectively. The treatments were i.e., 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. All the unit plots were equally provided with triple super phosphate (TSP), muriate of potash (MOP) and gypsum at the rate of 180, 100 and 180 kg ha^-1, respectively as basal dose. Prilled urea (PU) was applied in two equal splits, the first one-half of urea as basal and second half at 30 DAS before flower initiation. On the other hand, USG (2.7 g) was placed in 5, 10 and 15 cm depth of soil and each at basal, 10, 20 and 30 DAS following treatment variables. Intercultural operations were done as when required. The crop was harvested when 90% of the plants become golden yellow color. The seeds were measured at 10% moisture content. Yield components like branches plant^-1, siliquae plant^-1, seeds siliqua^-1, 1000-seed weight (g), seed yield (t ha^-1), stover yield (t ha^-1), biological yield (t ha^-1) and harvest index (%) were recorded after harvest. Data was analyzed following ANOVA technique using statistical program MSTAT-C and mean differences was adjudged with LSD at 5% level of significance.
