Study Notes

Introduction

  • This study investigated the use of organic fertilizer made from coffee grounds, mango peels, and banana peels to improve lettuce growth.
  • Lettuce cultivation typically takes 1-2 months in the summer.
  • This can be longer in other times of the year.
  • Organic fertilizer is a sustainable alternative to chemical fertilizers.
  • Fruit peels, particularly banana peels, are a significant contributor of waste globally.
  • The study aims to determine the effectiveness of this fertilizer blend in relation to plant height, leaf numbers, and stem diameter.
  • This study aims to decrease the time for cultivation of lettuce.

Statement of the Problem

  • The study seeks to determine the potential of a fertilizer blend using coffee grounds, mango peels, and saba banana peels for lettuce cultivation.
  • The researchers aim to improve lettuce growth by using organic waste material.
  • The study aims to address issues related to suboptimal composting as well as the use of local organic waste as an alternative to chemical fertilizers.

Significance of the Study

  • This study provides farmers with practical guidelines on the use of local organic waste.
  • Implementing sustainable waste management practices.
  • Using locally sourced organic waste will enhance agricultural productivity and food security.
  • This study aligns with the Sustainable Development Goals (SDG 2: Zero Hunger) and SDG 12 (Responsible Consumption and Production).

Scope and Limitations

  • The study focuses on the effects of organic waste blends on lettuce growth.
  • The study period is from August 2024 to November 2024.
  • The scope considers factors that include plant height, leaf numbers, and the overall biomass yield.
  • The study accounts for outside factors including weather and pest infestations.

Materials and Methods

  • The study was conducted in a demo farm in Muntinlupa City, Philippines.
  • The researchers obtained permission for use of the site.
  • Three plots of land were prepared, each with dimensions specified in the study.
  • The soil was mixed to provide optimal conditions.
  • A total of 180 lettuce seedlings were planted, evenly spaced.
  • The study utilized a Randomized Complete Block Design (RCBD) with two replicates per treatment.
  • The study used three types of organic fertilizers, based on different ratios of mango peels (MP), banana peels (BP), and spent coffee grounds (SCG) and comparing them with a control (no organic fertilizer).
  • Different blends of each were tested (i.e. F1 and F2).
  • Measurements were conducted for the number of leaves, plant height, and stem diameter.

Results and Discussion

  • The results from F1 and F2 showed a significant positive difference in growth results compared to the control.
  • No significant difference in growth was detected between the two treatments, in all the parameters studied.
  • A 33.22 % increase of plant height using F1 and a 21.28 % increase of plant height using F2 fertilizer compared to the control fertilizer was found.
  • There was no significant difference between the two treatments (F1 & F2).
  • The highest mean for number of leaves occurred in F2 and the lowest in the control group.
  • F2 showed the highest stem diameter.

Summary, Conclusion, and Recommendations

  • The study demonstrates the effectiveness of combining coffee grounds, mango peels, and banana peels as an organic fertilizer.
  • Both experimental treatments were effective implying that the fertilizer mixes were equally effective and that organic manure can be a good alternative to synthetic fertilizers.
  • Further research of different blends of banana peel, mango peel, and spent coffee grounds are necessary to find the best overall combination.
  • Future research should incorporate additional variables (chemical composition, nutritional composition of the lettuce, and physical properties).
  • Future researchers should also carefully consider weather and pest infestations.
