3. INTRODUCTION
 Soil type has a great effect on root growth, which is strongly
inhibited by hard soil and more growth in porous soil.
 Influences the ability of the root system to extract adequate water
and nutrients from the soil.
 Also the nutrient availability in the soil affects the growth.
 Biofertilizers are added to increase this nutrient availabilty and
increase growth.

4. Compost as BIOFERTILIZERS
 Compost is the end product of
various degradation process of
organic matter.
 The compost almost
resembles humus in the soil.
 Compost can be made from
food waste, crop residue Farm
yard manure of cow, horses etc.

5. Benefits of
vermicompost
Earthworms keeps the
soil well aggregated by
adding mucus
Has high N, P,
K value Low capital
investment
and simple
technology
Makes soil pH
neutral
Enriches soil with
microorganism
Increases
fertility
Helps reduce
waste that would
otherwise cause
pollution
Enhanced seed
germination,
root and shoot
growth

6. How do soil type affect growth using
Cicer arietinum

7. Why Cicer arietinum was chosen ?
• Cicer arietinum germinates very quickly.
• It does not require extra special care and grows in minimal
conditions as well.
• It can also grow in partial shade conditions.
• Chickpeas are frost tolerant and grow best where daytime
temperatures range between 21-26ºC and where night
time temperatures do not dip below 18ºC.

8. Types of soil taken

9. EXPERIMENT
Two different soil type was taken field soil and soil mixed with
vermicompost.
15 seeds of pre soaked Cicer arietinum were sown in each pot.
For 13 days the pots were observed and the data was collected for
each day.

10. Along side a rapid field test for carbonate, sulphate,
nitrate, organic matter, and chloride was conducted.
The results of rapid field test are as follows -
RAPID FIELD TEST

12. Conclusion of rapid field test
Vermicompost contain maximum minerals and cations like
NO3
-, SO4
2-, organic matter, chloride and carbonate.
Organic matter high due to activity of earthworm. High
concentration of ions added by activity of decomposers on
dead insects and waste.
Field soil has low amount of minerals ions as
compared to both Vermicompost but enough to support
to plant growth.
Due to increased human activity, microbial growth has
reduced and decrease in mineral content.

13. DAILY ANALYSIS REPORT

16. FINAL RESULT ON DAY 13
GARDEN SOIL
FIELD SOIL

17. 1st seedling germinated – in pot containing 50% garden soil and
50% Vermicompost on day 2, whereas in field soil 1st seedling
germinated on day 4.
1st leaf seen – in pot with 50% garden soil and 50 %
Vermicompost at about 1 cm above soil by day 4.
Rapid growth - By day 11 almost all the seeds have
germinated and grown into plants in garden soil but in even
by day 14 only 4 plants have grown along with 2 new
germinated.
Growth parameters

18. The experiment was performed in the late February i.e. beginning of
spring wherein the growth of plants is maximum as the temperature is
moderate neither very low nor very high thus supporting plant growth.
 It helps in improving the physical, chemical and biological
structure of soil.
 Mucus and humus of vermicast bind the soil particle together and
make it well aggregated.
The improved soil condition brought by the addition of
Vermicompost helps the plants tremendously. Enhanced seed
germination, improved root and shoot growth bring about increase in
plant growth, in field increases the crop yield.
