Description A Long-term field study was carried out to compare the impact of ten-year old
plantation of ten multipurpose tree species, viz.,Terminalia arjuna, Azadirachta
indica, Prosopis juliflora, Pongamia pinnata, Casuarina equisetifolia, Prosopis alba,
Acacia nilotica, Eucalyptus tereticornis, Pithecellobium dulce,andCassia siamea
ontree growth, biomass yield, and physico-chemical properties of sodic soils representing
major tract of salt-affected soils of the Indo-Gangetic Alluvial Plains of India.Maximum (100
%) survival was recorded withTerminalia arjuna, Prosopis juliflora,Pongamia pinnata,and Pithecellobium dulcewhereas minimum (50%)inProsopis alba. Maximum plant height (9.3m) was recorded with Eucalyptus tereticornis followed by Casuarina equisetifolia (8.2 m) whereas; minimum plant stature was attained byCassia siamea. Prosopis juliflorareported maximum diameter at stump height,crown diameter, lopped biomass, and litter fall at all the growth stages. Prosopis juliflora also produced highest aerial biomass (70.27Mg ha1 )followedby
Acacia nilotica (63.09Mg ha1) and Casuarina equisetifolia (53.11Mg ha1). Significant improve-
ment in soil pH and electrical conductivity; exchangeable sodium percentage; organic
carbon; and available N, P, and K was recorded under tree plantation than natural fallow. Significant reduction in soil bulk density (from 1.57 to 1.21 mg m3) and increase in porosity (40.7 to 54.3%) and infiltration rate 2.10 mm day1 to 26.30 mm day1 was recorded under tree plantations. It is concluded that tree species like Prosopisjuliflora, Acacia nilotica,and Casuarina equisetifoliahave a significant impact on soilproperties, which could help to rehabilitate the sodic wastelands in the region.
