Frequency and period of pruning affect fodder production of Gliricidia sepium (Jacq.) Walp. and Pterocarpus erinaceus Poir. in the Sahel

Fodder collection from natural stands generates income in peri-urban areas in the Sahel. Fodder banks show financial and ecological benefits, as increased demand requires sustainable tree management. Fodder production from two commonly used species, Gliricidia sepium (Jacq.) Walp. and Pterocarpus erinaceus Poir. was evaluated for combinations of variety, year, period, height, and frequency of pruning. In the first experiment (1997–2000) fodder production increased with tree age, but in the second period (2012–2015) fodder production was declining in all treatments. Overall, the data suggest that for marketable fodder production a 3-month pruning interval is maintained for G. sepium and a 4-month interval for P. erinaceus .
