Abstract/ Executive Summary:

Objective of the study was to know the proximate composition of the rice straw of Modern rice varieties. Proximate composition of straw of 3 recently developed rice varieties was determined. The straw of all the varieties had similar nitrogen content varying between 0.47% and 0.51%. Phosphosous potassium, sulpher content was less than 0.2%. The sodium and Calcium content of BR22 was comparatively lower than other two varieties. The contents of all other elements were similar.

Keywords: Rice, straw and Quality

Location: Grain Quality and Nutrition Division laboratory, BRRI HQ

Start Date: 01-07-1992

End Date: 01-06-1993

Program Area: Quality and Nutrition

Commodity: Rice

Objectives:

To know the proximate composition of the rice straw of Modern rice varieties.

Methodology:

The varieties of BR22, BR23 and Nizersail were grown at BRRI farm using 90-90-40-60-10kg/ha of urea-TSP-S-Zn with an exception of 45kg/ha urea for Nizersail. The rice plant was cut at ground level and grains were separated from the plant. The plant was then dried and grounded. Nutrient contents were determined using standard procedure of BRRI.
