Abstract

Farming is everyone's business, not only because it supplies our food but
because it is the root of so many industries and a large portion of Canada's trade and
commerce. Our experiment aims to explore the growth rate of produce in both fertilized
and salinated environments. Over a 15-day experimental period, we monitored the
biomass of green onions grown in a fertilized environment using bananas and a highsalt
environment, with regular water as a control. We hypothesize that if salt impairs
plant development, then green onion bulbs grown in a high-salinity environment will
have a lower biomass than onions exposed to no treatment. Additionally, we
hypothesize that if banana peels are an effective fertilizer, then green onion bulbs grown
in a fertilized environment will have a greater biomass than onions exposed to no
treatment. An analysis of variance test (ANOVA) with Tukey's post hoc test was used to
identify a statistically significant result. Our results suggest that there is a significant
difference between the growth of green onions exposed to salt and the control group.
However, we fail to reject the null hypothesis that there is no difference between green
onion growth in the control group and when exposed to banana peel fertilizer. As such,
we can conclude that the salt impaired growth and extend the evidence proving salt is a
factor of concern when looking to increase crop yield
