Agronomic performance of naked oat (Avena nuda L.) and faba bean intercropping

The most common cereals for faba bean (Vicia faba L.) used in intercrops is conventional oat (Avena sativa L.) An alternative to oat may be naked oat (Avena nuda L.), whose oil content and quality is double. Here, intercropping of naked oat with two different faba bean cultivars (determinate-high ta...

An alternative to oat may be naked oat (Avena nuda L.), whose oil content and quality is double. Here, intercropping of naked oat with two different faba bean cultivars (determinate-high tannin and indeterminate-low tannin) was compared with sole crops of each species in 2006-2008. The treatments were: sole naked oat at 500 kernels m², indeterminate sole faba bean at 50 seeds m², determinate sole faba bean at 70 seeds m², and an additive series of 25%, 50%, and 75% of faba bean seeding rate mixed with the naked oat seeding rate.

Raising the faba bean seeding rate in a mixture from 25% to 75% reduced oat grain yield from 630 (determinate cultivar) to 760 kg ha-1 (indeterminate cultivar) but increased faba bean grain yield from 760 kg ha-1. Higher yield and leaf area index (LAI) and photosynthetically active radiation (PAR) values show that the indeterminate cultivar of faba bean is more suitable in mixture with naked oat.
