BSN Increases Yield Regardless of Fertiliser Rate

It is very common in untreated seed for nutrient levels to be at suboptimal levels, these levels are also negatively affected by annual climatic conditions including drought and flood, meaning that the seeds nutrient levels can change and be negatively impacted from one year to the next. It has been scientifically demonstrated by RLF and independent research scientists that BSN improves seed (internal) concentrations. Phosphorus and trace elements will directly influence yield potential regardless of fertiliser rate applied to the soil.

Proof that higher Phosphorus in the seed gives higher Yield regardless of fertiliser rates

Available Phosphorus

Work by Bolland and co-workers (2006), as shown in the graph to the right, shows higher yield of medic seed with high seed phosphorus regardless of the rate of super phosphate applied with seed at sowing.

Seed yield in medic having low (0.40%) and high (0.64%) phosphorus in the seed. Yield increase due to seed phosphorus was 27% and 23% higher at 110kg and 910kg Super phosphate respectively. (Adapted from Bolland etal 2006)

What does this show

This shows how important the phosphorus levels in the seed are to future yield.

It doesn’t matter how much fertiliser you use – if the phosphorus levels in the seed are higher, the yields are greater. This shows that by using BSN you can ensure that phosphorus levels in the seed are higher, and therefore the potential for yields will be greater, regardless of the rate of fertiliser used.

Seed Manganese Response

This graph demonstrates that root growth is better with high manganese in seed regardless of soil manganese supplied. Similar responses to higher levels of Seed Zinc where Zinc is deficient in the soil.

What does this show

This shows that the nutrient in the seed – in this case Manganese – has a better effect and result regardless of the availability of the element levels in the soil.

It confirms how important nutrient levels are in the seed compared to the nutrient level in the soil.

Seed Zinc Response

What does this show

Seed Zinc response shows us that the higher the seed nutrient level, the more response there is, regardless of levels in the soil.

This reinforces the importance of ensuring the seed has the optimum nutrient balance because the soil levels will have little direct result during germination and early growth.
