Crop management manual

For the best results, the mixture Vital with the NutriFibre®  technology should be managed differently from other ryegrass. Therefore, the instructions stated below related to field preparation, right soil type, optimal fertilising and correct harvesting methods contribute to a high forage yield. This crop management manual provides you with the necessary information to get the most out of your Vital grass.


Field requirements 

Weed pressure

Select field with low weed pressure or make use of a false seed bed.

Soil structure Loosen up deep soil levels because the roots must be able to grow deep.
Seedbed  Prepare a fine and firm seedbed.


Sowing recommendations

Sowing period  March - April and August - September 
Soil temperature > 12C
Seed rate* 50 - 60 kg/ha
Sowing depth 0.5 - 1.5 cm 
Row distance

< 8 cm

*If no clovers are included in the mixture, 6-8 kg of red clover or 2-3 kg of white clover can be added.



Management after sowing 

     Time to establish  

Vital with NutriFibre® establishes slow since it first builds a deep root system, contributing to excellent drought tolerance.

Management after sowing (1)

Spray to tacle broad-leaved weeds when grasses are > 5 cm.

Management after sowing (2)

Don’t apply slurry or animal manure in the period between sowing and the 1st cut.

First cut after sowing Harvest the 1st cut after sowing when grass is not higher than 15 cm.
Autumn maintenance

The optimal stubble length of 9 - 10 cm grass height should be reached before winter.


Fertilization recommendations per cut per hectare*

Nitrogen (N) 90 kg
Phosphate (PO4) 30 kg
Potassium (K2O) 96 kg
Magnasium Oxide (MgO) 10 - 28 kg
Calcium Carbonate (CaCO3) 320 kg per year 

*The exact amounts depend on country and soil type. Analyse the soil to set up a fertilizer plan.


Harvesting recommendations  

Moment of harvest 3000 - 3500 kg DM/ha
Cutting height   > 8 cm
Cutting interval 4 - 5 weeks
Field period

Vital with NutriFibre® needs less drying time than perennial rye grass. Cut the Vital fields at last and start collecting them at first.

Making silage <30 - 35 % dry matter at least to prevent molding
Inoculants Use silage inoculants for optimal conservation



Dry matter yield*

Dry matter yield first year

2 - 12 ton DM/ha

Dry matter yield from its

  second year onwards

Up to 18 ton DM/ha

*Depending on management and fertilization.
