Abstract/ Executive Summary:

Two field experiments were conducted at the Bangladesh Rice Research Institute (BRRI) farm, Gazipur and at BRRI Regional Station farm, Camilla during the Boro season 2006 to evaluate the performance of the Super Greenfield Organa chemical fertilizer (SGOF) on the growth and yield of wetland rice. Eight treatment combinations were tested. The application of SGOF in combination with chemical fertilizer significantly increased the plant height, tiller and panicle number, grain and straw yields of BRRI dhan29 over the control at both Gazipur and Comilla locations. It was observed that the application of SGOF @ 500 kg/ha + Recommended dose of urea produced reasonable higher yield as good as soil test based (STB).

Keywords: Super greenfield, Organa-chemical, Growth and yield, Wetland rice

Location: BRRI farm, Gazipur and BRRI Regional Station Farm, Comilla

Start Date: 00-10-2006

End Date: 00-00-0000

Program Area: Crop-Soil-Water Management

Non-commodity: Performance

Objectives:

To determine the effect of organo-chemical fertilizer on growth and yield of rice

Methodology:

Two field experiments were conducted at BRRI farm, Gazipur and BRRI Regional Station Farm, Comilla during the Boro season 2006. The soil of the experimental fields was clay-loam in texture and slightly acidic in nature (pH 5.63-6.13). The experiments were laid out in a randomized complete block design with three replications. All organic and inorganic fertilizers were applied at final land preparation. Urea was applied in three equal splits: 1/3rd as basal, 1/3rd at early tillering stage and the remaining 1/3rd at 5-7 days before panicle initiation except T₃ and T₈ treatment. In these two treatments, basal urea was not applied . BRRI dhan29 was used as test crop at both the locations. Forty-five day old 2-3 seedlings/hill were transplanted with 20 cm x 20 cm spacing. Necessary intercultural operations were done as and when required. At maturity, the crop was harvested from 5 m² area at the centre of each plot and grain yield was adjusted to 14% moisture content. The straw yields were recorded at oven dry basis.

Achievement/Findings:

It is concluded that the treatment T3 (SGOF) @ 500 kg/ha + Recommended dose of urea (90 kg N/ha) may be the most economically viable fertilizer management packages for Boro rice cultivation at BRRI farm, Gazipur. The treatment T₃ may be recommended for the poor and middle class and T₅ (75% of T3 + 25% of STB) for the rich farmers of Camilla region.
