Inflation has been one of the main issues that the Philippines has been dealing with, especially in
navigating life with COVID-19 in the new normal. This study aimed to address the food security
problems in the Philippines by comparing various fertilizer alternatives namely, organic
fertilizer, chemical fertilizer, and used coffee grounds fertilizer. A field experiment was
conducted to see the effect of organic fertilizer, chemical fertilizer, and used coffee grounds
fertilizer on the yield and growth of Ipomea Aquatica (kangkong) in home gardening. An
interview was also conducted with sixteen (16) respondents with regards to human preference on
the physical characteristics and taste of the kangkong crop. The data between the relationships
between the independent variables and fertilizers regarding physical characteristics was analyzed
through One-Way ANOVA and the data for human preference was analyzed through the use of
Kruskal-Wallis Test through SPSS. The results on the data for human preference showed that the
kangkong 3 (chemical fertilizer) stood up compared to the other two kangkong which was
indicated by 62.5% overall appearance and 37.5% on overall taste among the kangkong. The
proponents recommend using the coffee ground as a fertilizer as based on the computed data, the
percentage of each fertilizer doesn't have a huge gap, especially on the taste, which is the
criterion that is the most important for people who source their vegetables on planting. This
study will help future researchers to consider a fertilizer with a high acidity level. Additionally, it
will contribute to the community that promotes home gardening to have a much healthier and
breathable air.
