Abstract

Agroforestry is a dynamic and ecologically-based natural resource management system that integrates trees in the farm to diversify and sustain smallholder production for increased social, economic and environmental benefits. An important and beneficial feature of agroforestry system is the inflow of nutrients into the system, through leaf litterfall, stemflow and throughfall. This study determined the tree and crop growth performance, crop productivity, and water and nutrient flows in a Experimental set- Gmelina arborea - Zea mays hedgerow agroforestry system in Claveria, Misamis Oriental, Philippines two spacing treatments (1m x 3m and 1m x 9m) ups of G. arborea - Z. mays hedgerow systems with were established in the study Standard sampling protocols were employed for the set of area. parameters monitored and measured in the study Growth performance of trees along the hedgerows and maize crop in the alley areas was better in the wide spacing treatment (1m x 9m) than in the narrow spacing treatment (1m x 3m). Nutrient contents of maize biomass and Gmelina leaf litterfall were likewise higher when grown in wide spacing treatment. Higher amount of nitrogen (N) from leaf litterfall was observed in the same treatment. About 54% of the incoming rainfall landed in hedgerow systems as throughfall and only 1% as stemflow in both spacing treatments. Depths of stemflow and throughfall vere slightly higher in the narrow spacing treatment. Water passing through stems and barks of trees showed higher K contents than throughfall. Throughfall however, exhibited higher ammonium (NH,* and nitrate (NO;') contents. The results of this study showed that tree spacing greatly affected nutrient dynamics of hedgerow agroforestry systems. Inputs of nutrients into these hedgerow systems were via stemflow, throughfall, maize crop residues and leaf litterfall. The nutrient outflow of the two hedgerow spacing treatments was via crop harvest. In the wide spacing treatment, higher crop productivity per unit area contributed greater NPK losses compared with narrow spacing treatment.
