Abstract
The study was conducted on the performance and relative suitability of different nitrogen fixing and non-nitrogen fixing tree species planted on loamy skeletal soils. The survival and growth observations recorded after 7 ½ yrs. of planting showed that Albizia procera as the most suitable species with highest relative score among nitrogen fixing species while Azadirachta indica was found to be the most suitable among non-nitrogen fixing group.
On the basis of relative suitability indices plants were grouped into four categories. Species scoring highest number (75-100) were categorized under most suitable while those with indices below 45 were not considered as suitable for planting in these type of degraded soils. Dalbergia sissoo, Dalbergia latifolia, Azadirachta indica, Emblica officinalis, Gmelina arborea and Cassia siamea were found to be most suitable while Acacia catechu and Acacia benthamii were unsuitable.
