This  study  aimed  to   determine  the  acceptability  of   charcoal  and  native coffee as growth enhancer and determine which are  the best growth  enhancer for pechay seeds. Specifically, it sought to  answer  the  following  question: What is  the growth of pechay in terms of number of leaves and height among four (4) treatments: Treatment-1:  charcoal on soil with pechay seeds, Treatment-2: Native Coffee on soil with pechay seeds, Treatment-3: Pechay seeds with no growth enhancer, and Treatment-4: Pechay seeds with Mixing coffee and charcoal on soil? And is there a significant difference on the growth of pechay in terms of number of leaves and height among four (4) treatments?

             Further, the researchers hypothesized that there is no significant difference on the growth of pechay in terms of number of leaves and height among four (4) treatments.

             This   study   utilized   the   quantitative-experimental research  design  to  describe  and quantify the acquired data. It basically used  four-group  design  for  the acceptability of the products and four-group design for the effectivity of the product.

In terms of height, the setup-1 obtained the highest mean height of 4.42, interpreted as “taller”. Followed by the setup-2 which obtained a mean height of 4.20, also interpreted as “taller”. Then, setup-3 obtained a mean height of 4.00, means “taller”. While, the control group obtained the least mean height of 3.17, means “tall”. Hence, this table implies that setup-1 is more effective as growth enhancer for pechay plant in terms of height.

In terms of number of leaves, the setup-1 obtained the highest mean of the number of leaves of 14.30, interpreted as “leafiest”. Followed by the setup-2 which obtained a mean of 13.10, also interpreted as “leafiest”. Then, setup-3 obtained a mean of 12.80, means “leafiest”. While, the control group obtained the least mean of 8.80, means “leafier”. Hence, this table implies that setup-1 is more effective as growth enhancer for pechay plant in terms of the number of leaves.

 

The Analysis of Variance (ANOVA) confirmed that there is a significant difference on the Growth of Pechay Plant in terms of height since the probability value obtained is 0, means highly significant. Therefore, the hypothesis tested on height was rejected.

The ANOVA confirmed that there is a significant difference on the Growth of Pechay Plant in terms of number of leaves since the probability value obtained is 0.017, means highly significant. Therefore, the hypothesis tested on height was rejected.

 

Based from the results and findings of this study, the researchers concluded that the plant growth enhancer (PGE) made from spent coffee and charcoal is effective on the growth of pechay plant in terms of height and number leaves. Hence, the growth of pechay plant differ in terms of height and number of leaves wherein the three (3) setups involved in this study were more effect than the control group.
