Summary
This report was composed to examine whether the significance of the minerals Nitrogen and phosphorous benefit the growth and development of the cereal crop wheat. Also whether any deficiencies of these minerals reduce; height, tiller number and root development meaning significantly low dry matter yields.
The research draws attention to the fact that over the 90 day trial the Complete nutrient formula containing both nitrogen and phosphorous had the heaviest wet and dry weight with better quality florescence needed for maximum production in the cropping industry. On the other hand the other plants lacking the number of tillers, seed head and overall quality of the florescence show signs of deficiencies being smaller in size and slight ‘off colour’ on the leaves and base of the plant.

Aims of the Trial
This trial was designed to measure the significance of the minerals Nitrogen and Phosphorous to the growth and development of the cereal crops wheat.
The following hypothesis were tested
A. A deficiency of either nitrogen, phosphorus or both nutrients will reduce the height of the cereal crop.
B. Tiller counts of the plants deficient in nitrogen or phosphorus will be significantly lower than that in the control group and the plants lacking both nitrogen and phosphorus will have a further dramatic reduction.
C. Root system development in plants deficient in phosphorus, a nutrient that promotes root growth, will be significantly reduced compared to the
