The effect of drought on the development and yielding of two different varieties of the fodder broad bean (Vicia faba minor).
A factorial experiment was performed in the fodder broad bean to analyse effects of soil drought on the development and yield components of two varieties of different morphotype: 'Nadwiślański' (traditional) and 'Tim' (determinate growth habit). Plants were grown in Mitscherlich's pots under three different soil moistures: 70%, 50% and 30% of field water capacity. The soil water shortage contributed to a considerable depression in the developmental characteristics and yield traits of both varieties. Under all conditions, the variety 'Nadwiślański yielded more seeds than did 'Tim'. The traditional variety was more resistant to drought than the new 'Tim'.
