Measuring physical quality of paddy
What are the properties of paddy that require measuring?
Using the paddy crack detector, count the number of cracked grains in a 100-grain sample; then compute the % of cracked grains using the equation:
Using the Vernier caliper or photographic enlarger, collect 20 paddy samples at random from each replicate and measure the dimensions to obtain the average length and width of the paddy grains. To obtain the paddy shape, the following equation will be used.
Paddy will be classified based on standards set by the International Organization for Standardization (ISO) for paddy.
