Effects of different nutrient conditions on plant growth of wheat seeds ________________________________________ The objective of this investigation was to determine the effects of limiting nutrients on plant growth in different treatment. Nutrient availability is an important factor in plant growth as it enhances the processes taking place in the plants such as primary and secondary metabolic processes. In this investigation, wheat plants were observed in different chemical treatments with limitations to nutrients using statistical analysis. Students were required to scientifically determine whether or not different nutrient conditions affected the overall plant growth over duration of time. The shoot length and biomass of 20 random leaves grown in different chemical media 's were measured and this data was used to calculate statistical calculation such as the mean, standard deviation and t-value which was compared to the critical t-value to determine whether or not the null hypothesis was rejected. It was statistically calculated that the treatments that were nitrogen deficient and phosphorus deficient had a p-value greater than 0.05 and treatments that were water and potassium deficient had a p-value less than 0.05 in both the plants shoot length and biomass. This lead to the conclusion that nitrogen deficient and phosphorus deficient treatments did have an effect on the plant growth of wheat plants.
