  abstract = {{F}orest seed bank assessments are scarce in {M}adagascar and thus little is known about the relationships between the seed banks and vegetation dynamics on which secondary succession processes rely. {T}he objective of this paper is to analyse the effects of slash-and-burn agriculture on soil seed banks and their dynamics along secondary forest successions. {T}he aim of this work is to determine the effects of agricultural practices (cropping duration, tillage regime and fallow age) on seed bank density ({SBD}) and diversity ({SBSR}) during secondary succession periods (<25 years). {C}ropping duration was divided into three classes: (i) short (1–2 years), (ii) medium (3–5 years) and (iii) long (6–11 years). {T}illage regime during crop successions was divided into three categories: (1) no tillage (only direct sowing is observed), (2) light tillage (after direct sowing, local shallow tillage is observed) and (3) heavy tillage (after direct sowing followed by light tillage practice, complete tillage practice is observed). {F}ifteen fallows subdivided into three regrowth age classes (2–6, 10–12 and 14–22 years) were surveyed. {F}allow age is the main driver of {SBD} and {SBSR}: they increase with fallow age, regardless of cropping duration and tillage regime. {SBD} and {SBSR} recovery always occurs but is slower under long cropping duration (3–11 years) and heavy tillage regime because cropping duration helps to maintain a high level of wind-dispersed seeds during secondary succession and tillage regime contributes to reducing the proportion of viable seeds.},
