Abstract

The experiment was conducted in the existing plantations of A. mollissima having three density classes (D1, D2 and D3) at Dr. Y. S. Parmar University of Horticulture and Forestry Solan (India). Adjacent grassland was considered as control. Three exotic grasses viz., Setaria sphacelata var. Narok (S1), Setaria sphacelata var. Kajungula (S2) and Panicum maximum (S3) were planted under each density class and the grassland in the month of July. Survival and growth parameters (density and basal area) of these grasses were recorded after first growing season. Survival (%), density and basal area of exotic grasses decreased significantly under trees. Survival (%) varied from 73.33 to 82.22 in grassland and 50.00 to 7.8% under plantations. Density (tillers/m2) of exotic grasses varied from 28.42 to 39.47 in grassland and 11.92 to 27.22 under plantations. Basal area (cm2/m2) of the grasses ranged from 9.56 to 43.05 in grassland and 0.58 to 15.19 under plantations. D3 density of trees showed more adverse effects on grasses followed by D2 and D1. Among the three grasses Panicum maximum showed more tolerance to the effect of trees. However, the other two grasses showed moderate success under trees.
