Abstract: Disposal of waste is a universal problem. Available methods require manpower, lot of money and area to manage waste. Plant generating waste is a type of organic waste which can be use better for soil conditioning and as a tonic for maintain their healthy status. Vermicomposting is a suitable alternative for safe, hygienic and cost effective disposal of organic solid wastes. The present work has been done to reveal changes in physical factors during vermicomposting and also compare the result between different types of composting mixtures. The pH was measured during vermicomposting and found that at initial stage pH was 5.6 ± 0.1 in 100 % leaf litter (LL), 5.8 ±0.1 in 50% LL while 8.5 ± 0.1 in 100% cattle dung. At the end of process pH raised and set up to 8.1 ±0.1 in 100 % leaf litter 8.0 ±0.1 in 50% LL and 100% CD. Obtained result explore that temperate of 100 % leaf litter, 50 % leaf litter (LL) and 100 % cattle dung (CD) was slightly elevated (35.9, 36.5ºC and 38.5ºC ±1ºC respectively) at beginning phase and later came down to ambient level (21.5ºC ± 1ºC). The moisture content was recorded 48.25 % and 46.32 % in 100 % leaf litter, 50 % leaf litter (LL) respectively while 60.35 % recorded in 100 % cattle dung. During the initial time loss of water increased but latter stage was it was set at constant point. Reduction of biomass was also studied during process and found that in 100 % leaf litter biomass was reduce up to 22 cm; in 50 % leaf litter this reduction was found about 21cm while in 100 % cattle dung this reduction was found 8.6 cm.
