Organic Fertilizer for Lettuce Growth Study

A sustainable alternative to chemical fertilizers, using organic waste materials to improve soil health.

The process of growing lettuce plants.

Materials like mango peels, banana peels, and spent coffee grounds.

A mixture of decomposed organic materials used to enrich the soil.

Starting lettuce seeds to grow into plants.

Moving young plants from one place to another.

Removing water from fruit peels to preserve them.

Essential elements found in lettuce for health benefits.

A byproduct of the coffee brewing process, often discarded as waste but potentially useful as an organic fertilizer.

A likely abbreviation for Spent Coffee Grounds, Possible abbreviation.

Essential nutrients in soil like Nitrogen (N), Phosphorus (P), and Potassium (K).

Harmful effects of a substance on plants.

Higher SCGPF levels are linked to more bacterial colonies in the soil.

10% SCGs in soil is the best amount for plant health. Higher amounts can harm nutrient absorption.

Nitrogen in a form (NO3- or NH4+) that plants can easily absorb.

A chemical compound mixture containing nitrogen (N), phosphorus (P), and potassium (K), used to promote plant growth.

A type of fertilizer made with nanoparticles that are more easily absorbed by plants, promoting efficient nutrient uptake.

Farming practices that aim to maintain environmental balance and productivity over the long term, minimizing negative impacts.

A natural, organic fertilizer derived from banana peels, rich in potassium and other nutrients beneficial to soil health.

The negative effects of excessive chemical fertilizer use, including water contamination, soil degradation, and greenhouse gas emissions.

Essential nutrients needed in large amounts by plants for healthy growth and development, including nitrogen, phosphorus, and potassium.

Banana peel-based fertilizer offers a sustainable alternative to chemical fertilizers, improving soil fertility, reducing waste, and promoting plant growth.

Nanoparticles in nano fertilizers are smaller than the pores on plant roots, allowing for easier absorption and better nutrient utilization.

A type of experimental design that divides the experiment into blocks, minimizing the impact of extraneous variables. This ensures a more reliable comparison between treatments.

The factor being manipulated by the researcher to see its effect on the dependent variable.

The factor being measured in the experiment to observe the results of changing the independent variable.

Factors other than the independent variable that could potentially influence the dependent variable.

The group in an experiment that does not receive the treatment, used as a baseline for comparison.

The specific condition or intervention applied to a group of subjects in an experiment.

The repetition of the experiment multiple times with the same conditions to increase reliability and accuracy.

The proportion of nitrogen (N), phosphorus (P), and potassium (K) in a fertilizer.

The experiment used two blends: F1 (10g BP, 20g MP, 15g SCG in 1L water) and F2 (40g BP, 15g MP, 70g SCG in 1L water).

Waste peels were collected, washed, cut into small pieces, dried (banana peels for 2 hours, mango peels for 1.5 hours), and ground into powder.

Discarded mango peels, banana peels, and spent coffee grounds were collected as materials for the fertilizer blend.

The first fertilizer blend, consisting of 10 grams of banana peel powder, 20 grams of mango peel powder, and 15 grams of spent coffee grounds mixed in 1 liter of water.

The heavier fertilizer blend, consisting of 40 grams of banana peel powder, 15 grams of mango peel powder, and 70 grams of spent coffee grounds mixed in 1 liter of water.

100mL of the assigned fertilizer blend was applied to each lettuce plant twice a week during the growing phase.

Three parameters were measured at the end of the growing phase: stem diameter, plant height, and number of leaves.

The dried and ground mango peel powder, banana peel powder, and spent coffee grounds were stored in separate sealed containers.

The process of seeds sprouting and growing into young plants.

Using everyday scraps like coffee grounds or banana peels to provide nutrients to plants.
