Evaluation work by Agrovista indicates berseem clover as the best companion for OSR, either alone or in mixture with vetches. Can suppress small-seeded vegetables up to 1 month after incorporation. 0000001220 00000 n
As growing plants, they also mop up any excess nutrients which reduces soil losses over the winter months. Berseem Clover (Trifolium Alexandrinum) - Berseem is a fall-planted clover that does best in heavier soils that may stay wet for long periods. One farmer reported a lab report of 26.2 percent crude protein and a relative food value of 151 on this third cutting of green chop.

Where vetches are included in the mix, Astrokerb will kill the vetches prematurely and because they have a very low C:N ratio, nitrogen would be released quickly at a time when the OSR isn’t growing. 0000003861 00000 n
Increasing soil organic matter and reducing soil disturbance means a more biologically active soil with a more stable structure. Agrovista advice is for growers to use the same seed rate as for the OSR crop and to mix the two different seeds together in the drill.
“We’ve trialled it in wet areas of fields and you could see it to the line – the OSR looked much better than where a companion wasn’t planted,” he says. %PDF-1.3

In France, companion cropping has been proven to deliver considerable benefits to growers, including reduced impact from pests and weeds. Astrokerb (aminopyralid+ propyzamide) will take out berseem clover but at the time of use, late Nov/Dec, the clover is likely to die anyway. 04063574, Companion cropping – Berseem clover improves soils. 0000010041 00000 n
For millennia, it has been the foundation for agriculture in the Nile Delta, featuring salt tolerance, high nitrogen fixation, and a synergistic relationship to alfalfa.

CPM is published ten times a year – monthly from February to December – and is sent out free of charge to qualifying individuals. “We’re also finding we have less pigeon damage because there’s such good ground cover, they can’t land in the crop.”.
“The roots improve soil drainage, getting water away from the rooting zone, but also works the other way and sucks water out of the soil too.”. On the continent, flea beetle incidence is said to be reduced but this isn’t something that Agrovista has been able to substantiate in their trials programme.

Because of its winter hardiness, Bigbee has about the same range of adaption as arrowleaf and crimson clovers.
On the other hand, vetches are better able to capture nitrogen – typically 40kg N /ha, compared to 10-15kg N /ha by the clover.
It has a shallow taproot. “It makes a really good job of establishing the OSR, leaving ground much more friable and easier to work the following autumn.”. Ś��ut_�כ�a=��
N1R�1+��Ɨ�Wy#D Berseem clover plants (Trifolium alexandrinum) belong in the legume family, which means their roots bear nodules which fix nitrogen in soil. “But like habitual smokers, most farmers are addicted to deep cultivation because it makes them feel better for a short period of time while ignoring the real damage they’re doing. 0000004940 00000 n
He’s trialled a number of establishment methods and settled with direct drilling using a Moore Unidrill, mixing berseem clover seed with the OSR seed.

Frosty, while preserving its Mediterranean genetics, has been bred for later maturity, cold tolerance, productivity, and nutritional value. Berseem clover is a winter annual legume with oblong leaflets and hollow stems. Trifolium alexandrinum (Egyptian clover, berseem clover) is an annual clover cultivated mostly in irrigated sub-tropical regions, and used as leguminous crop. He’s been using both cover crops and companion crops on the farm for a number of years but this is the first year that he’s planted his entire OSR acreage together with a companion.

Where nitrogen is applied in the autumn for OSR establishment, companion crops will mop up any that isn’t required by the crop and release it in the spring. Furthermore, the trials sites are situated across the country to ensure that local climatic conditions – as well as various soil types – are taken into account.
Particularly valuable is when it comes to stabilising stubbles after harvest to prevent run-off and mopping up residual phosphates from slurry and digestate applications. Frosty Berseem clover has very low hard seed counts, allowing the plant to focus on quick establishment and rapid growth.
Mycorrhizal fungi in the soil greatly improve the ability of plants to access soil resources but OSR roots won’t interact with them.
Berseem thrives in loams and clays with a pH of 6.5 - 8.5 and tolerates poorly drained soils. This in-depth programme is dedicated to finding practical solutions to crop production problems, whether in the broad-acre arable crops or in the pursuit of high-value fruit and vegetable produce.

For most situations, berseem clover alone provides an effective companion at a cost of around £10/ha. Quantity Discounts for Berseem Clover - Nitrocoated Seed (Lb) Buy 10 for $4.49 each. Berseem clover is a small seed, similar to OSR, and can be planted using any drill on existing row widths.

Carbon:nitrogen, or C:N ratio, is a measure that roughly reflects the amount of woody material to green, soft plant tissue. Flowers are round, white and approximately 2 cm in diameter.

But in the spring, savings on nitrogen have been the norm, without any reduction in yield. Leaflets are commonly 4–5 cm long and 2–3 cm wide. 0000003086 00000 n

Plant 1/4 inch deep. ** Berseem clover is a excellent cool season clover used for wildlife food plots, cattle forage and ground cover. Berseem is a warm-season crop sown in the spring in northern states where it grows as a summer annual. Tests have shown that Berseem is very palatable and bloat problems have never been reported.
Vetches are likely to require application of clopyralid (after March 1) to remove them.

Companion crops with a low C:N ratio decompose quickly, releasing nitrogen back in the soil for the OSR crop to utilise in the spring. Berseem is a warm-season crop sown in the spring in northern states where it grows as a summer annual. 0000067421 00000 n

crop production magazine UK’s best-read arable journal. Berseem clover is widely adaptable to all but sandy soils and is tolerant of soil salinity. “The OSR follows the berseem clover roots down and soils benefit from the increased root systems,” he says. “A good subsoiler” is how Robert Atkinson describes the berseem clover he uses in cover crop mixes and as a sole companion to oilseed rape on his 180ha farm, to the north of Doncaster.
Planting berseem clover seed impregnated with mycorrhizae is one way of quickly bringing phosphate into play, which would otherwise be locked up, getting more value out of the soil.

Continuing work on cover crops (including berseem clover and vetches) is focusing on soil health, with the aim of putting tangible figures on their benefits to the soil and to the grower. **Berseem Clover is currently a pre-order item but is expected to be available early October. Berseem clover alone is enough to aid establishment, rooting and release some N. But if nitrogen capture is the prime objective, then the addition of a vetch to the clover is useful. Alexandria is a «multi-cut type berseem clover.
Good for wildlife, cattle forage and as a soil builder. Agrovista has spent four years looking at whether the same benefits apply under UK conditions. This is a winning trait when combined with heavy nitrogen feeders like soybeans and corn .

Note to Certified Organic Growers: All our cover crop seed is untreated, non-GMO seed. “It’s very important not to overfill the drill because the berseem clover seed is about half the size of OSR seed and could potentially settle out towards the bottom of the drill.
CPM (Crop Production Magazine) is a controlled circulation magazine for UK arable farmers, farm managers, agronomists, machinery dealers and other arable supply industry professionals. Berseem clover prefers soils that are slightly alkaline (pH greater than 6.0) and grows well in all soil types except deep sands with low moisture retention. 0000003921 00000 n

This is conventional seed, but all seeds are coated with Nitro-Coat Organic, which is an OMRI listed coating. The biggest benefits from the roots of berseem clover are seen in soils where there’s been little cultivation. It is an important winter crop in Egypt, where it may have been cultivated since ancient times, and was introduced into northern India in the early nineteenth century. Part of the ongoing work by Agrovista is looking at the performance of berseem clover against a subsoiler and comparing fuel consumption under different tillage approaches. 0000022283 00000 n
