A field experiment was carried out to estimate biomass production, carbon stock and economic performance of Melia dubia under agri-silviculture system. The grain yields of pearl millet were significantly lower under M. dubia plantations (852–2920 kg ha–1) compared to sole crop without trees (3182 kg ha–1). Maximum biomass production of 6-yr-old M. dubia planting was recorded as 74.9 t ha–1 and minimum was 53.9 t ha–1. Contribution of M. dubia to total carbon stock and carbon dioxide sequestration was observed in the range 27.0–37.5 and 98.9–137.5 t ha–1 respectively. The net returns obtained from the tree were lowest ( 116,134–182,885 ha–1) when compared to the tree + crop ( 139,953–209,650 ha–1) system. The lowest net returns were observed in sole crop without trees ( 27,351 ha–1). Thus, M. dubia plantations contributed towards higher carbon dioxide sequestration and economic performance of agri-silviculture system was higher compared to sole crop.

Abstract


A field experiment was carried out to estimate biomass production, carbon stock and economic performance of Melia dubia under agri-silviculture system. The grain yields of pearl millet were significantly lower under M. dubia plantations (852–2920 kg ha–1) compared to sole crop without trees (3182 kg ha–1). Maximum biomass production of 6-yr-old M. dubia planting was recorded as 74.9 t ha–1 and minimum was 53.9 t ha–1. Contribution of M. dubia to total carbon stock and carbon dioxide sequestration was observed in the range 27.0–37.5 and 98.9–137.5 t ha–1 respectively. The net returns obtained from the tree were lowest ( 116,134–182,885 ha–1) when compared to the tree + crop ( 139,953–209,650 ha–1) system. The lowest net returns were observed in sole crop without trees ( 27,351 ha–1). Thus, M. dubia plantations contributed towards higher carbon dioxide sequestration and economic performance of agri-silviculture system was higher compared to sole crop.
