Chili Test Report
Test period: 27 July 2021 to 13th November 2021
Site and Location: Lim Chu Kang Lane 4
Crop Type: Chili
Test Product: Group 1 Control, Group 2: 100% fertilizer with
PN PP, Group 3: 50% fertilizer with PN PP
Environment condition: Outdoor
Prepared by: Johnny
Duration : 14 weeks
Evaluation Objective:
1. To test effectiveness of microbes on the chili growth, protection against pest and diseases and yield production.
2. To test effectiveness of varying fertilizer percentages
Experimental Plan:
There were 3 groups set up in this experiment with varying conditions. Group 1 was the control group where no microbes were used with 100% fertilizer throughout the experiment. Group 2 was grown with 100% fertilizer together with MIT microbes. Group 3 was grown with 50% fertilizer together with MIT microbes. There were 14 plants growing in each group.
Observations:
After the plants had started to bear fruit, photos were taken to compare observations of the plants size, number of fruits and health between the 3 groups.
Group 1
Group 2
Group 3
Plants that were grown in group 3 and group 2 were notably bigger in size when compared to group 1, where the plants were the smallest in size. This could have been due to no deposits of any MIT microbes used and the health of the plants may not be getting enough nutrients to excel in growth like the other 2 groups. Another interesting observation was group 2 & 3 had flowers at an earlier stage compared to group 1 which is the trigger of fruiting begins.

Data collection
Harvesting Record
The results above have been separated and represented in graphs to depict the differences observed between the 3 groups below.
Based on this result we are able to see that Group 2 has the greatest yield at 1509g followed closely by Group 3 at 1412g and lastly Group 1, the contro group at 535g. Group 2 has a 7% increase in yield in comparison to group 3 and a 182% increase in yield in comparison to group 1. Group 3 has a 163% increase in yield in comparison to group 1 and thus, we can observe that using 100% and 50% fertilizer with MIT microbes produces the best total yield mass as compared to the control group.
Based on the results obtained above, Group 2 has the greatest average weight of one chili at 1.76g followed by Group 3 at 1.44 g and lastly Group 1 at 1.40g. Thus, we can observe that with the use of 100% fertilizer and microbes, we can obtain fruits with the greatest average weight compared to the control and 50% fertilizer.
Blind Test Results
Blind test was conducted on 12 people and they were asked to determine which fruit tasted the best. The results were tabulated in the graph below.
We can observe that 58% of the tasters agree that the fruits in Group 2 are the best tasting ones, 33% agree that group 3 are the best tasting ones while the remaining 9% agree that group 1 are the best tasting ones. With this we can observe that using microbes will help improve the taste of the chili.
We can observe that 57% of the tasters agree that the chili from group 1 were the worst tasting ones while 21% of the tasters agree that the chili from group 3 were the worst tasting ones. The remaining 22% agree that the chili from group 2 were the worst tasting ones.
Conclusion
Based on the data acquired above, we observe that the incorporation of MIT microbes help the chili plant improve its yield as observed in the harvest of Groups 3 and 2 compared to the harvest in group 1 which has no microbes implemented. It also observed that the size of the plants affects the yield as seen in the greater yield results of groups 3 and 2, which have relatively bigger plants compared to group 1 which had a smaller yield and smaller plant sizes.
