Saffron is an annual plant usually grown as a perennial crop, with well-known problems, which arerelated to the reduction of soil fertility (mainly caused by weeds, biotic pathologies and micronutrientsscarcity) that in the long run determine a dramatic yield reduction and overexploitation of the soil. In thisview, crop rotations are considered the traditional antidote to the soil sickness. However, the evidenceof the effects of previous crop on saffron stigma yield and corm production is slender and fragmentary. Atwo-year study was carried out to evaluate the effect of three different previous crops (faba bean, saffronand fallow) on saffron stigmas yield and replacement corms production. Two different corm densities (30and 45 corms m−2) were also studied. Faba bean as previous crop determined the highest performancein terms of flower number (up to 400 flowers m−2), stigma yield (up to 2 g m−2) and replacement corms(up to 4.7 kg m−2). This paper, to our knowledge, is the first experimental based research on the effectsof previous crop on stigma and corm yield of saffron.
