Effect of integrated manuring on growth and yield of Centella asiatica (L.) Urb.

Abstract

Centella asiatica is an important ethnomedicinal plant. Effect of integrated manuring on growth of Centella asiatica was investigated using vegetative clones from Kirtipur, Kathmandu. The plantlets were grown in earthen pots containing soil, with integrated manuring [Urea(%):FYM(%), 75:25; 50:50; 25:75], individual manuring (100% Urea, 100% FYM) and control conditions (no manure). The experimental design was completely randomized and each treatment had forty plants. We examined number of leaves per ramet, petiole length, specific leaf area, number of primary branches, number of flowers per ramet and plant biomass. The number of leaves per ramet, leaf area and number of flowers per ramet were significantly higher in integrated manuring than other treatments. Biomass production in integrated manuring (50% Urea and 50% FYM) was seven times higher than in control; it was five times higher than in complete organic manuring (100% FYM) and 1.5 times higher than in inorganic manuring (100% Urea).
