we have concluded that when adding extract to the soil, it has contributed to the growth of tomato plant increasing its branches and number of leaves. The highest growth rate has been 36.92 cm in the soil containing the extract, while the same has been 17.57 cm in the soil not containing the extract.

Hi Durra Moosa Al Bulushi Dareen Salem Al Faris Esraa Khalaf Al Dohali,
It is very interesting project and it is nice to know that egg shells help tomato.
Here are my questions.
(1) when you said you mixed egg shell extract, did you weigh the egg shells that you put it in?
(2) what would you think what will happen to your results if you add more egg shell extract in or decrease the amount of egg shell extract?
(3) It is nice that you measured tomato height for several weeks. However, it would be more interesting if you could tell us about the amount of tomato fruits that it produced between these two types of soil?
(4) As your data showed the conductivity differed between two treatments, why soil with egg shell had lower conductivity readings?
Nicely done on GLOBE data entry.
