Control (no penac) Block 4 and 29 (wheat) and Block 12 and 21 (barley)

Results

Repetition 1 as follows:

(Control is no. 4)

It can be seen that the control did well which shows that it was a good year, but it is also well comparable with the trial results where combinations were used with seed treatment and leaf applications.

In this case the control did not even feature (13,3) against the treated seeds with 13,8. It is, however, interesting to see that the combination of seed treatment and leaf applications fared very well.

Here it is clearly shown why a combination of penac is so important for commercial farming practises.

In all cases where the penac combination was used the yield increased.

The seed siftings were an average of 1,1

The moisture was an average of 12

Repetition 2 as following:

(Control is no. 29)

It can be seen that there is a good balance between the control and combination applications. hl mass was excellent in all cases.

Here the control did not even feature against the combinations.

The graph shows clearly that combinations of penac products can insure a better crop yield.

The seed siftings were an average of 1,1

The moisture was an average of 12

Yield: 119,45%

4. Soil treated with penac-k, seed with penac-p and foliage spray with penac-p leaf

hl mass: 76

Yield: 108,95%

6. Soil treatment with penac-k and foliage spray with penac-p leaf

Protein: 13,15

Yield: 125,2%

7. penac-p leaf application

hl mass: 76,5

Protein: 13,55

Yield: 123,1%

8. penac-p seed treated and penac-p leaf application

hl mass: 76,5

Protein: 13,5

Yield: 109,45%

Conclusion:

The trials of this year compared to the trials of the previous year proved that the farmer needs penac because:

We have successfully proven that by using penac the grade quality and quantity increased.

1. By using penac-k on the soil, the soil quality and microbial life increase as well as the water retention capacity.

2. By treating the seed with penac-p better germination takes place which strengthens the plant at an early stage.

3. Due to improved root growth, the plant can assimilate nutrients and give a better yield.
