Abstract/ Executive Summary:

The Panicle number/m² varied significantly among the treatments and the highest number were found in USG treatment. The grains/panicle and spikelet sterility (%) did not vary significantly among the treatments. The grains/panicle was found maximum at USG treated plot and minimum was found at farmers’ treatment. The farmer’s treated plot showed the highest percentage of sterility whereas USG treated plot observed the lowest percentage of sterility. The variation of grain yield among the treatments was statistically significant, where 49% higher grain yield was found in USG and NPK briquette treated plot over farmer’s plot.

Keywords: NPK briquette, USG, Farmer’s practice

Location: Uzirpur, Barisal

Start Date: 01-11-2013

End Date: 30-06-2014

Program Area: Crop-Soil-Water Management

Commodity: Fertilizer

Objectives:

The experiment was conducted to determine the optimum level of fertilizer requirement for growing rice during Boro season.

Methodology:

The treatments were; i) BRRI Recommended fertilizer doses, ii) Urea super granule treated plot, iii) NPK briquette treated plot and iv) Farmer’s practice. The experimental area was laid out in design RCB with three replications. Forty one day old seedlings of BRRI dhan29 were transplanted at 20- × 20 cm spacing. The unit plot size was 5- × 4 m². BRRI Recommended fertilizer doses were; Urea at 298 kg ha^-1, TSP 82 kg ha^-1, MOP 82 kg ha^-1, Gypsum 63 kg ha^-1, ZnSO₄ 7 kg ha^-1, whereas the farmer’s applied Urea @200 kg ha^-1, TSP 65kg ha^-1, MOP 35kg ha^-1. Urea super granule 2.7 g was applied in the field at 10 DAT and NPK briquette (2.4 g) was also applied in the field at 9 DAT. The full dose of TSP, MOP, Gypsum and ZnSO₄ were applied during final land preparation. Urea was top dressed at 20 & 40 DAT. Irrigation water, insect and weed control were done as and when necessary. Data on plant height, grains/panicle, sterility (%) and grain yield were recorded at harvest.
