Faba Beans

Winter pulse that lifts nitrogen for the next crop

Vicia faba

In stockDownload tech sheet

Faba bean is a winter growing pulse, or food legume crop. It is a cool season crop in Australia, planted in mid to late autumn and harvested in late spring to early summer. Faba beans may be grown where rainfall is higher than normal and spring temperatures are milder, and they respond well to irrigation on heavy clay soils.

Key attributes

  • Winter growing pulse and food legume
  • Rotation crop with winter or summer cereals or cotton
  • Nitrogen fixation makes more soil N available to the next crop
  • Break crop that reduces crown rot and root lesion nematode
  • Responds well to irrigation on heavy clay soils
  • Green manure option where soils are degraded

About this variety

Faba beans can be grown as a component of a rotation based on winter or summer cereals or cotton, or as part of a green manure where soils have been degraded in organic and physical fertility. Crop rotations which include faba bean in sequence with winter cereals and summer cereals, or cotton, are more productive and profitable than those in which legume phases are excluded, because yields and quality of cereal grain and cotton fibre are usually higher after faba bean.

Nitrogen fixation in the root system of the faba bean makes more soil N available to the next crop, reducing the need for fertiliser N, and in some cases adding to soil organic N. Up to 40% of the N in a faba bean crop is underground. Levels of soil-borne diseases (like crown rot) and pests (like root lesion nematode) of wheat are reduced by growing faba bean as a break crop.

Faba bean plants in Australia grow to a height of 1.5 m at maturity. The plant is erect, and produces stems from its base, and the taproot bears a profusion of fibrous roots in the top 30 cm of soil. Seeds vary in size depending on variety, from large flattened beans (also known as broad beans) through medium sizes to smaller, rounded seeds like field peas; varieties with medium sized seed are the main types grown in Australia.

Planting & grazing notes

Faba beans are planted in mid to late autumn and harvested in late spring to early summer. The crop develops rapidly from July to September during flowering and podding, when daytime temperatures are 15–25°C; flowering stops as temperatures approach 30°C. Ensure faba bean is sown within the recommended window: early sowing within the window is important in the medium and low rainfall zones, but responses are inconsistent in the high rainfall zone. Sowing rate should be based on target plant density and will vary with seed size. Faba bean seed should be inoculated with Group F inoculant. Sowing equipment may need to be modified to accommodate the large seed; sow 5-8 cm deep, and dry sowing is an option. Paddocks may require rolling to make harvest manageable. Plants can tolerate mild frost during vegetative stages, but severe frosts can deform and lodge stems and can cause death of flowers and immature pods after flowering.

Disease & pest resistance

A good overall level of disease resistance, including being less susceptible to chocolate spot and rust, and resistant to Ascochyta blight.

FAQs

What pulse can I put in my rotation to cut crown rot and nematodes in the wheat after?

We recommend Faba Beans as a break crop. Growing faba beans reduces soil-borne crown rot and root lesion nematode in the following wheat. They also fix nitrogen, and up to 40% of the crop's nitrogen is held underground for the next crop. Cereal yields and grain quality are usually higher after faba beans.

How deep do you sow faba beans?

We recommend sowing Faba Beans 5–8cm deep, and dry sowing is an option. Inoculate the seed with Group F rhizobia before sowing. Sow in mid to late autumn, within the recommended window, because early sowing matters more in medium and low rainfall areas. You may need to roll the paddock to make harvest easier.

What seeding rate do I need for faba beans?

We base the seeding rate for Faba Beans on your target plant density and the seed size of the batch, so we don't publish a single fixed rate. Talk to us with your target density and we will work it out. The seed is large, so your seeder may need adjusting; sow 5–8cm deep with Group F inoculant.

Will a winter pulse cope with frost in our district?

Faba Beans tolerate mild frost during vegetative growth. Severe frost can deform and lodge stems, and after flowering it can kill flowers and immature pods. The crop flowers and pods from July to September when daytime temperatures are 15–25°C, and flowering stops near 30°C. Choose paddocks and sowing times that reduce frost risk at flowering.

What winter crop will fix nitrogen and improve my heavy clay soil?

We recommend Faba Beans. They respond well to irrigation on heavy clay soils and suit areas with higher rainfall and milder springs. Inoculated with Group F, they fix nitrogen, and up to 40% of the crop's nitrogen is underground, making more soil nitrogen available to the next crop and reducing your fertiliser nitrogen needs.

Is there a pulse with decent disease resistance for higher rainfall areas?

We recommend our Faba Beans, which have a good overall level of disease resistance: they are less susceptible to chocolate spot and rust, and resistant to Ascochyta blight. Faba beans suit areas with higher rainfall and milder spring temperatures, and respond well to irrigation on heavy clay soils. Plant in mid to late autumn and harvest in late spring to early summer.

Can I use a winter pulse as a green manure on run-down soil?

Yes, we recommend Faba Beans as a green manure where soils have been degraded in organic and physical fertility. The erect plant grows to about 1.5m, and when inoculated with Group F it fixes nitrogen, making more soil nitrogen available to the next crop. It also reduces crown rot and root lesion nematode in the cereals that follow.

When should I plant and harvest broad beans as a paddock crop?

We recommend planting Faba Beans in mid to late autumn and harvesting in late spring to early summer. The crop develops quickly from July to September as it flowers and pods, and flowering stops as temperatures approach 30°C. Medium-seeded types are the main ones grown in Australia; the large flattened types are the ones known as broad beans.

Faba beans vs field peas as a break crop, which suits better?

Faba Beans suit heavier clay soils and higher rainfall areas, and they reduce crown rot and root lesion nematodes for the next wheat crop. Our Coogee Field Peas suit 350mm+ rainfall on sandy to heavy soils, tolerate low pH and salinity, and are flexible for hay, forage or manure. Both fix nitrogen, and both lift the cereal crops that follow.

Do winter pulses like waterlogged or wet paddocks?

We don't list waterlogging tolerance for Faba Beans, so we suggest paddocks that drain reasonably well. They do respond well to irrigation on heavy clay soils and suit areas with higher rainfall and milder springs. Talk to us about your specific paddock; for very wet or salty ground, a perennial pasture such as Puccinellia may suit better.
