Abstract/ Executive Summary:

This study was conducted with the objective of to determine the variation in chemical quality influenced by rice cultivation seasons. BR3 was cultivated in boro and aus season. Fertilizer doses, irrigation, pest management and other management were followed by the season wise BRRI recommendations. Unparboiled milled rice was used for chemical analysis. Amylose content (%) and protein content (%) both were found higher in aus sample. Average amylose content was 25.3% in aus grains which was 25.1% in boro grains. On the other hand, protein content was 8.1% in boro sample and 8.8% in aus season.

Program Area: Quality and Nutrition

Commodity: Rice

Objectives:

To determine the variation in chemical quality influenced by rice cultivation seasons.

Methodology:

BR3 was cultivated in boro and aus season in the GQN Division's experimental field. Fertilizer doses, irrigation, pest management and other management were followed by the season wise BRRI recommendations. Samples were collected from the experimental field excluding border effect. Unparboiled milled rice was used for chemical analysis.
