Abstract:

Status of agroforestry systems and assessment of tree diversity in the existing agroforestry systems of North-eastern part of Karnataka under irrigated ecosystem was carried out during 2015-16. There were six prominent agroforestry systems practiced by the farmers and the majority farmers practiced bund planting (43.06%) followed by boundary planting (19.44%), silvihorti systems (12.50%), scattered planting (4.17 %) and silvipasture system (2.78 %) while block plantation system was found to be associated with one or other systems on the farm land. 52 tree species were recorded with a mean species density of 9.04 ha-1 and mean number of trees were 104.24 ha-1. Further, significantly higher number of trees per hectare occurred in silvihorti system (123) followed by boundary planting (105.43) and bund planting (93.10) whereas least number of trees per hectare were recorded in silvipasture system (48.00) followed by scattered planting (69.33). Interestingly, significantly higher Shannon diversity index was observed in scattered planting (1.79) followed by silvipasture system (1.72) whereas lower value was recorded in bund planting (1.04). Among different categories of holding size, higher number of trees per hectare was recorded with large farmer (122.48) followed by medium farmer (100.45); lowest being with small farmer (91.82). Among the districts, significantly higher mean number of species per hectare was observed in Kalaburagi district (11.25) followed by Bidar (9.08) and lower mean number of species per hectare was recorded in Koppal (7.75) followed by Ballari (8.58). Tectona grandis, Azadirachta indica, and Cocus nucifera were the preferred perennials.
