## SEED TREATMENT

BIO-GEL is most effective in seed treatment (seed sterilization in case of inorganic farming) of cereal, leguminous, technical and other crops.

Dissolve 2.0 l of BIO-GEL in 10 l of water. It is enough for 1000 kg of seeds. BIO-GEL is compatible with all weed and pest killers.

## ECONOMY

For example, the rate of winter wheat seeding per 1 hectare is approximately 200 g of seeds. For processing seeds will need 0.4 liters of BIO-GEL".

The cost of seed processing will cost 0,4L * 5.5 $/L = 2.2 $ per hectare .

### SEEDS SPROUTING

Take Petri dishes or disposable plastic flat dishes. Put a four times folded paper napkin on the plate bottom. Using a syringe (without a needle) add the same amount of water (dropwise) to the each napkin, for example, 10 ml.

On top of each napkin put the same number of seeds, for example, 5 g or 100 seeds. Distribute the seeds evenly on the wet napkin.

Cover the top with another napkin, folded 4 times. Moisten the top napkin with another 10 ml of water. Thus, the amount of water in each plate is the same and equals to 20 ml. Cover the plates with similar ones turned upside down.

Put samples in a room with a temperature above + 15 ° C and (necessarily!) cover all the plates with a piece of cloth (possibly a dry towel). Thus, we create the same temperature conditions for germination.

If Petri dishes made of glass are used the number of seeds should be reduced to 2-2.5 g.

On the third day open carefully the cups and compare them. If necessary, add the same amount of water in drops to all samples. The final analysis of the results is carried out on the fourth day. Determine the number of seeds that have not germinated (this is easier, since there are relatively few such seeds).

To obtain the quantitative characteristics cut off carefully the sprouted roots and tops of wheat using a sharp knife or scissors. Weigh them carefully to the hundredth of a gram, then compare and draw conclusions.

It is advisable to establish the optimal concentration of BIO-GEL for certain type and variety of seeds. To do this, you can make 10%, 15% and 20% BIO-GEL solution for spraying adding 5 g, 7.5 g, 10 g respectively to 50 g solution.

Water is taken as the control, it should be added in the amount of 1 ml per 100 g of seeds.

To determine the effectiveness of BIO-GEL you can compare the weight of seeds before and after germination, for example, after 4 days. It is convenient to introduce an efficiency coefficient K as a ratio of the seeds weight after and before germination.

Seeds weight (g) at the experiment start | 4 days later / seeds weight Р1 (g) | Gain / Difference in seeds weight after 4 days Р2 (g) | Efficiency coefficient К = Р2 / Р1 | |
---|---|---|---|---|

Sample 1 / treatment with water | 2,48 | 8,15 | 5,63 | К0=2,27 |

Sample 2 / treatment with 10% BIO-GEL solution | 2,55 | 9,06 | 6,81 | К0=3,02 |

Sample 3 / treatment with 20% BIO-GEL solution | 2,52 | 10,66 | 8,14 | К0=3,23 |

Sample 4 / treatment with 30% BIO-GEL solution | 2,40 | 9,70 | 7,30 | К0=3,04 |

### CONCLUSION

Thus, the best result K1 = 3.23 was obtained using 20% BIO-GEL solution, i.e. 2 liters per 10 liters of water for every 1000 kg of seeds. For 4 days the weight of seeds increased more than 3 times.

If we compare the gain in seeds in water K0 = 2.27 with the gain in BIO-GEL K1 = 3.23 it is easy to calculate the difference in the efficiency of using BIO-GEL, it will be:

n = (К1 - К0) / К0 * 100% = (3.23-2.27) / 2.27 * 100% ≈ 42% (!)

Make it yourself and be convinced of it!

We have made experiments with dozens of seed varieties. Based on the research, the universal dose of 20% BIO-GEL solution, i.e. 2 l per 1000 kg of seeds can be recommended.
