Abstract/ Executive Summary:

Milling is one of the important parameters of grain quality. Milling yield has direct effect on consumer's preference and also on market price. Objective of this study was to determine the effect of field dried aromatic rice on milling performance. This study was conducted at Grain Quality and Nutrition Division Laboratory, BRRI, Gazipur. Effect of field drying on milling yield of three aromatic rice varieties was not significant but significant effect was observed for Basmati386.

Keywords: Arometic rice, Milling yield, Milling performance

Start Date: 01-07-2008

End Date: 30-06-2009

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To determine the effect of field dried aromatic rice on milling performance

Methodology:

Milling performance of aromatic rice important for its market value. This study was conducted at Grain Quality and Nutrition Division Laboratory, BRRI, Gazipur. BRRI dhad37, BRRI dhad38, BRRI dhad39 and Basmati386 were supplied by FMPHT Division, which were dried at different level and conditions such as T₁ = No field drying, T₂ = 4 days left in the field, T₃ = 6 days left in the field, T₄ = 8 days left in the field and T₅ = 10 days left in the field. All the varieties were milled in the laboratory to determine the milling performance.

Achievement/Findings:

Milling yield of four aromatic long grain varieties (BRRI dhad37, BRRI dhad38, BRRI dhad39 and Basmati386) was acceptable level (66-71%). There was no significant difference among the treatments. It can be said that field drying has no significant effect on the percent of milled rice. This might be due to lack of cracking in the endosperm. On the other hand, comparing the different treatments of a variety, there was no significant difference on head rice yield except BRRI dhan39, which was dried in the field for 10 days that produced 92% head rice yield compared with other treatments. Similarly, field drying effect was found in Basmoti 386, the low head rice yield was in the treatments T₂, T₄ and T₅ but there was significant difference with the treatment T₁ and T₃. In conclusion field drying effect was observed only for the variety Basmoti 386.
