Crack Detector
Using the Paddy Crack Detector, count the number of cracked grains in a 100 grain sample then compute the % cracked grains using the equation:
Grain Dimensions
Using a 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 can be used:
Paddy can classified based on International Organization for Standardization (ISO) for paddy
Immature Grains
Select a 25 gm grain sample and select, segregate and weigh the immature grains in sample. Calculate the percentage immature grains in the sample using the formula:
Dockage in Paddy
Remove light foreign matter, stones, weed and seeds from a 100gm sample. Obtain the total weight then compute the dockage percentage as follows:
1000 Kernel Weight
Determined by counting and weigh 1,000 grains (paddy).
