The document describes an experiment to measure the imbibition rate of different types of seeds when soaked in water over 5 days. Red gram, rice, and mustard seeds were soaked and their increase in height was measured daily. The imbibition rate per day per seed was calculated for each type of seed by averaging the daily height increases and dividing by the number of seeds used. Mustard seeds had the highest imbibition rate per day per seed of 0.035, followed by red gram at 0.01, with rice having the lowest at 0.00325. The results showed that oil seeds have a higher imbibition rate than pulses, and pulses have a higher rate than cereals.

2. AIM:
To find the imbibition rate per day per seed of the
following types of seed : pulses, cereals and oil seeds.
NUMBER OF SEEDS TAKEN:
Red gram (Cajanus cajan) : 300
Rice (Oryza sativa): 500
Mustard (Brassica nigra) :100

3. PROCEDURE
• The 3 types of seeds are taken in a transparent glass
• Adequate amount of water is poured
• Height of seeds are marked everyday for 5 consecutive
days

5. Reading
Red gram : 1.5cm
Rice : 1 cm
Mustard : 1.5 cm
DAY 1

6. Reading
Red gram : 2.5 cm
Rice : 1.5 cm
Mustard : 2.5 cm
DAY 2

7. Reading
Red gram : 4.5 cm
Rice : 2 cm
Mustard : 5 cm
DAY 3

8. READING
Red gram : 4.5 cm
Rice : 2 cm
Mustard : 5 cm
DAY 4

9. Reading
Red gram : 4.5 cm
Rice : 2 cm
Mustard : 5 cm
DAY 5

10. Imbibition rate per day per seed
Imbibition rate per day of rice = (1+1.5+2+2)/4= 1.625
Imbibition rate per day of mustard = (1.5+2.5+5+5)/4=3.5
Imbibition rate per day of redgram = (1.5+2.5+4.5+4.5)/4 = 3.25
❖ IMBIBITION RATE PER DAY PER SEED =
(IMBIBITION RATE PER DAY/(TOTAL NUMBER OF
SEEDS USED)
❖ IMBIBITION RATE PER DAY = (V1+V2+V3+V4)/4

11. RESULT
Imbibition rate per day of rice = 1.625/500 = 0.00325
Imbibition rate per day of mustard = 3.5/100 = 0.035
Imbibition rate per day of red gram = 3.25/300 = 0.01
