The effect of two plant densities (20 and 40 plants/m2) on some key growth parameters and development of a Vicia faba var minor "Tapada da Ajuda" at various stages of crop growth. At final harvest, the dry-matter yield of the above-ground parts was 16.1 and 26.8 t/ha at 20 and 40 plants/m2 densities, respectively. The higher plant density had the highest crop growth rate (CGR), net assimilation rate (NAR), and photosynthetic active radiation efficiency (PAR). Towards the end of the season, the rates of senescence and pod abscission were much higher at the higher plant density
