Abstract

Pesticides are commonly used substances that are utilized to prevent bugs and unwanted forces from consuming or disrupting the growth of crops. Studies have shown that the chemicals used in many pesticides have various damaging effects on the growth, germination, and predictability of plants that they are applied to. One of the dangerous chemicals that are commonly used in many pesticides is ammonia, a nitrogen-hydrogen compound that is used in these pesticides due to their toxic nature. Previous research has shown that when isolated, the growth of several common crops (such as cotton and corn) is inhibited when grown with exposure to ammonia. The purpose of this research was to determine and identify the effects of ammonia on the rate of germination in one commonly grown crop in the United States, Fragaria ananassa (more commonly known as the strawberry). It was hypothesized that increased levels of ammonia concentrations would decrease germination times. The 150 trials of strawberries grown in biodegradable seedling trays were combined with various concentrations of ammonia (ranging from 1.2 to 2.4 ppm) and observed over the span of approximately seven weeks. With a p-value of 0.258, it was determined that the null hypothesis was failed to be rejected, and it was unlikely that the differences shown in the results were due to random sampling. From this, it was shown that despite the differences in the germination rates of the grown plants, the final results were not statistically significant enough to have any clear effects.
