The effect of the salt concentration of water on the productivity of Lupin plants over a fortnight.

Aim: The effect of the salt concentration of water on the productivity of Lupin plants over a fortnight. Hypothesis: Lupin plants that are watered with more salt will be least productive because an increased salt concentration in the water increases the osmotic gradient, which makes it difficult for plants to absorb water needed for photosynthesis, therefore they will be less productive and will die faster than plants watered with water with a lower salt concentration. …
