I picked a few more fava beans (Vicia fava) today. If you've never grown favas, I think you're missing out. They're not only easy to grow, they're also very delicious.
Fava beans, one of the world's oldest cultivated crops and native to the Mediterranean region, are also known as broad beans, horse beans, pigeon beans, and the like.
Fava beans are cool season beans. They are sown early in spring or late summer, as they do not grow well in warm weather.
I plant mine in late summer or early fall, they grow through the winter with hardly any effort on my part.
They lagged a little this winter due to lack of rains, but when the rains started coming around February, they had their growth spurt and soon they were flowering in my front yard - white, sweet fragrance greeted visitors as they walk towards my front door.
When I first started growing favas, I grew them only for cover crop in the winter. Fava beans, being in the Legume family, are capable of fixing nitrogen.
I tried eating the leaves one year. Another time, I tried the whole pods. Then more recently, the bean itself. I've acquired a taste for it and I like it. But It should be noted that some people of Mediterranean origin have a genetic trait (enzyme deficiency) that causes a severe allergic reaction to fava beans.
Lucky for me, I' m not allergic to fava beans and I look forward to planting more and eating more of this delicious and nutritious bean in the years to come.
Meanwhile, I better start planting some warm season lima beans, and transplant my 2 six-packs of beans from the Solano Community College plant sale. One can never have too many beans.
The nitrogen-fixing in the air is actually not done by the plant, but by the rhizobia bacteria in the nodules that form on the roots. In fact, it's a symbiotic relationship between the plant and the bacteria .
Rhizobia bacteria provide the legume plant with nitrogen in the form of ammonium and the legume plant provides the bacteria with carbohydrates as an energy source. The rate of N2-fixation is directly related to legume plant growth rate.
The nitrogen fixing is also affected by other factors like soil temperature, nutrient deficiency, soil moisture condition, which I will not get into.
And I did not find anything in published research that supports that idea of cutting off the stalks before the beans form to get more benefits from nitrogen fixing.
Hope that answers your question.
