Abstract
Field bean ( Vicia faba minor Beck), probably originated in the pre-historic period in the Middle East is, today,cultivated all over the world and counts among the most widely adapted grain legumes. In the Mediterraneanregion, field bean is considered a viable alternative to soybean to increase the sustainability of farming systems,because of its rusticity, and low fertilizer and pesticides requirement. Due to the indeterminate growth habit, intra-plant competition between reproductive and vegetative structures and among the developing pods may be great.Warmer winter temperatures, such those expected in the consequence of climate change, favour intra-plantcompetition, as they promote vegetative growth and flowering parallel to seed filling. A 3-year field experiment was carried out in temperate Mediterranean conditions on loam soil with moderatelyalkaline reaction. Imposed treatments were NP fertilizer supply (0, and 120 kg N ha and 100 kg P ha ) and seeddensity (100 and 60 seed m , respectively indicated as Fb100 and Fb60). Heavy rainfall in autumn-winter delayedsowing date, which was performed on October 26 2017, December 11 2018, and February 12 2020. Plants wereharvested twice each year, at the stage of full flowering with basal pods developing (65-73, BBCH) and when plantswere dead and dry (97, BBCH)I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
