Height of plant at maturity, measured from ground to the top of the spike. excluding awns
Counted as days from sowing to 50% of plants in flower. However, when planting in dry soils, in drland areas, it is counted from the first day of rainfall or irrigation which is sufficient for germination

If the is difficult to decide then the sodium hydroxide test can be used. Place grains in the petri-dish and add 25 ml of 5% solution NaOH for 60-90 minutes. Original red grains will be dark brownish orange. and white grains will be straw yellow.
