Forage Crops

STUBBLE TURNIPS
A fast growing crop, often
grown after first cut silage
for Summer grazing or after
Winter cereals for Autumn
grazing.
THERE ARE TWO TYPES OF STUBBLE TURNIP
-
Leafy type, providing good anchorage and Winter hardiness
-
Bulbing type producing predominantly large palatable bulbs

FORAGE RAPE
Forage Rape has the advantage of being a very fast growing forage crop, suitable for grazing by sheep or cattle. An ideal catch crop for boosting mid Summer forage production when planted in the Spring.

UTILISATION
USEFUL TIPS
Consider growing in a mixture with Stubble Turnips to combine the benefits of both crops
VARIETIES
NAPOLEON
- Very high yields and more Winter hardy than Emerald
- Quick to establish, ideal catch crop
- Can be mixed with grass to improve intake
- Has a wide sowing window
- Provides superb Autumn/Winter keep for finishing lambs and flushing ewes
- Stock should be introduced gradually and an area of grassland should be available for animals to return to; hay or straw should also be made available

PASJA Hybrid Root Crop
Pasja is a Turnip/Rape Hybrid that has the unique forage characteristic of producing a large amount of leaf and small bulb. The bulb is well anchored in the soil and has a crown which enables the plant to regrow after defoliation.
SOWING INFORMATION
| Sowing period |
= April - September |
| Direct Drill |
= 3.7kg/hectare (1.5kg/acre) |
| Broadcast |
= 5kg/hectare (2kg/acre) |
YIELD & FEED QUALITY
| Average dry matter yield |
= 10 tonnes/hectare |
| Regrowth potential |
= Very high |
| Crude protein |
= 24% |
| Metabolisable energy |
= 12.5 MJ/kg DM |
UTILISATION
FERTILISER
2 x 50kg bags of 25:10:18 per acre
USEFUL TIPS
For maximum regrowth and highest total yield, rapid grazing is essential and overgrazing resulting in damage to the crowns should be avoided.
-
Grazing 6-8 weeks from sowing is critical to future production and life span of the crop
-
Very successful when drilled direct into Cereal Stubbles
-
Must be back-fenced to facilitate regrowth
-
| Do not prolong commencement of grazing after 42 days in the hope of increased yield |
BENEFITS
- Very high yielding from successive grazings
- Hybrid plant type ensures very high plant vigour
- Suitable for all classes of stock
- Leafier than all other forage brassicas
- Highly productive and can produce up to 10 tonnes f dry matter through the growing season
- Pasja produces exceptionally leafy forage that has good nutritional value
- Pasja is more flexible than traditional forage rape and can be utilised over a much longer period
- An extremely cost effective and efficient forage crop
- Well anchored which prevents it being pulled out by stock

FODDER BEET
Fodder Beet is grown as a main root crop, which requires similar husbandry to Sugar Beet. It can produce substantial yields of high quality forage and is an excellent supplement to grass silage. It requires specialist harvesting equipment unless grazed in situ.
SOWING INFORMATION
| Sowing period |
= March - May after the last frost |
| Precision Drill only |
= 50,000 seeds/acre |

| Digestibility value |

| Metabolisable energy |
= 12.5-13.5 MJ/kg DM |
UTILISATION
USEFUL TIPS
Medium dry matter varieties tend to have a higher percentage of root above ground and can be lifted with a top lifter and therefore have a relatively low dirt tare. These can be fed whole to stock.
High dry matter varieties tend to sit further in the ground and require a Sugar Beet harvester to lift them. Due to the higher dirt tare and hardness of the root, these varieties may need to be chopped and washed before feeding.
After wilting, the tops may be fed to stock and can contribute a further yield of 3-4 tonnes protein rich dry matter per hectare.
