Abstract
Evaluation studies of fifteen multipurpose tree species (MPTs) for survival, growth and biomass production conducted under rainfed conditions at Agroforestry farm, Regional Research Station, GAU, Sardar Krushinagar indicated that at the end of 138 months, neem (Azadirachta indica) followed by rohida (Tecomella undulata), Siris (Albizia lebbeck), israel babool (Acacia tortilis) and khejri (Prosopis cineraria) recorded the highest survival under arid conditions of North Gujarat. Bakemneem (Melia azaderach) could not survive beyond ninth year. Israel babool followed by nilgiri (Eucalyptus tereticornis) and siris attained the maximum height, whereas rohida (Tecomella undulata) and deshi babool (Acacia nilotica) were slow in growth. Albida (Acacia albida) recorded the maximum collar diameter. Shisham (Dalbergia sissoo) had the highest above ground as well as underground biomass.
Based on survival, growth parameters (height and collar diameter), biomass production and utility as fodder, fuel, timber and cash earnings from tree products, neem and khejri were identified as promising MPTs for agroforestry systems in dryland agriculture.
