Abstract

The Lakha teak plantation site has situated in sub tropical deciduous forest area of Chhattisgarh. Teak is a major tree species with 32 other forest tree species in the plantation site. The study of ground leaf litter production in respect to rainfall variation from 2005-2011 shows that the average (±se; n=20) annual leaf litter production varied between 881 and 1370 g dry mass m-2 year-1. The 70-90% litter was produced in the dry seasons and 55-70% in wet seasons. On annual basis mean (±se; n=20) the highest total litter fall production varied 7.67±0.31Mg/ha/year in 2009 and lowest 6.00±0.33 Mg/ha/year in 2011. The plantation floor litter mass found highest 6.54±0.31 Mg/ha in year 2006 and 5.03±0.25 Mg/ha in year 2010. The decomposition of litters found highest in annual rates 13.87±1.06 Mg/ha/year in 2005 and 11.08±0.84 Mg/ha/year in 2010.
