Evaluation of performance of ferti-activator Sanbio PLANTA on the productivity, quality and economic aspects of silage maize variety ´Figaro´ in Germany

Drossdorf, Germany (September 01, 2014) – The cultivation of Maize in Germany is undertaken primarily to produce feed for cows, pigs and poultry (maize for silage including green-maize, grain maize, corn cob mix, maize coarse meal with husks). As well as being used for producing sugar, grain is also used by the food industry to produce maize-meal-products, snacks, cornflakes etc., and in pharmaceutical processes. As a renewable raw material, maize starch is used in the manufacture of paper and cardboard. In Germany the area cultivated with maize amounted to 2.52 million ha in 2017.

The aim of this study is to evaluate the effects of ferti-activator Sanbio PLANTA on productivity, quality and economic aspects of silage maize variety ´Figaro´.

Figure 1. Effects of Sanbio PLANTA on the development of plant, stalk and roots

The plants on the plot treated with Sanbio PLANTA have a more compact growth. The plants, which are 21.8% shorter, have a higher stability and are less sensitive to wind.

The roots of the treated plants show significantly higher growth, in particular root volume and root depth. The 50% longer roots allow the plant better access to water and nutrients and also anchor the plant better in the soil.

Figure 2. Effects of Sanbio PLANTA on weight and measure of cobs

The cobs harvested on the plot treated with Sanbio PLANTA have a higher weight (+25.9%), length (+29.6%) and diameter (16.6%).

2.2 Yield

Parameter   Control Sanbio PLANTA Sanbio PLANTA vs. CONTROL
Weight wet t/ha 48.515 49.354  
Moisture % 39.7 35.4  
Weight dry at 14% moisture **) t/ha 31.994 35.360 +3.365 t/ha
Yield       +10.5%

**) Calculation: Weight dry = Weight wet x [100 – (Moisture% – 14%) x 1.325 ] / 100

Figure 3. Yield calculated as dry weight at 14% moisture (t/ha) compared to untreated lot

The yield calculated to dry weight at 14% moisture was increased by 3.366 t/ha, resp. +10.5%, compared to untreated control lot.

3.  Conclusion

To summarize, the present study shows significantly positive effects of ferti-activator Sanbio PLANTA on productive performance of silage maize.

The positive effects at glance:

  • Higher harvest of +10.5%
  • Larger cobs (weight, diameter and length)
  • Stronger plants
  • Larger roots
  • Sustainable improvement of soil fertility.
