Abstract/ Executive Summary:

Objective of the study was to study the response of spacing of transplanting and depth of placement of urea super granules (USG) on the yield of Boro rice. he experiment was conducted at the Agronomy Research Field, Bangladesh Agricultural University (BAU), Mymensingh in the Boro season during 2008-2009. It belongs to the non-calcareous dark grey flood plain soil under the agro-ecological region of the Old Brahmaputra Floodplain. The experiment was laid out in a two factor randomized complete block design (RCBD) with three replications. The experiment comprised of two spacing of transplanting viz; 20 cm x 20 cm and 20 cm x 25 cm and three depths of placement of urea super granules viz; 6cm, 8cm and 10cm. Based on the results of the study it can be concluded that the spacing of transplanting of 20 cm x 20 cm in combination with 8 cm depth of placement of USG is the best for obtaining higher yield of Boro rice under the agro-ecological conditions of present study.

End Date: 00-00-2009

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To study the response of spacing of transplanting and depth of placement of urea super granules (USG) on the yield of Boro rice.

Methodology:

The experiment was conducted at the Agronomy Research Field, Bangladesh Agricultural University (BAU), Mymensingh in the Boro season during 2008-2009. It belongs to the non-calcareous dark grey flood plain soil under the agro-ecological region of the Old Brahmaputra Floodplain. The experimental field was medium high with moderate drained condition. The land was silty loam in texture having a soil pH 6.42, and moderate in organic matter content. The experiment was laid out in a two factor randomized complete block design (RCBD) with three replications. The experiment comprised of two spacing of transplanting viz; 20 cm x 20 cm and 20 cm x 25 cm and three depths of placement of urea super granules viz; 6cm, 8cm and 10cm. The sprouted seeds of BRRI dhan29 were sown in the nursery bed on 02 December 2008. Phosphorus @ 120 kg ha^-1 as triple super phosphate, potassium @ 60 kg ha-1 as muriate of potash, sulphur @ 40 kg ha^-1 as gypsum and zinc @ 10 kg ha^-1 as zinc sulphate were applied as a blanket dose in all the plots. A 2.7 g urea supper granule was applied at depths of 6 cm, 8 cm and 10 cm at the centre of four hills of two adjacent rows at 10 days after transplanting (DAT). Thirty five days old seedlings were transplanted on the well puddled experimental plots on 06 January 2009. The collected data were compiled and tabulated for statistical analysis and means were adjudged by Duncans Multiple Range Test (Gomez and Gomez, 1984).
