An experiment was conducted at college of agriculture, Nagpur during 2006-07 on comparative study the different methods of composting by using wheat straw. The experiment was laid out by randomized block design in seven treatments and replicated thrice. The different methods of composting were significant effect on granule size, humic substances, recovery and economics of wheat straw compost at maturity. The significantly highest humic and fulvic acid were recorded in Nagpur method (3.28 and 23.21%) followed by MA method (3.02 and 23.19%) and lowest in local method (1.66 and 20.34%), at maturity of compost. The recovery of compost was maximum in aerobic composting methods i.e. Nadep (54.33%), MA (48.52%), Nagpur (48.24%) and Heap (46.72%) than anaerobic composting methods i.e. Trench (42.95%), Pit (41.46%) and Local (27.99%). On the basis of initial construction cost the economics worked out, the maximum gross and net monetary return were recorded in Nagpur and MA composting methods Nadep, Trench, Pit, Heap and Local methods of composting. Similarly, maximum benefit: cost ratio was recorded by Nagpur and Ma (1.60) compost methods over other methods of composting.
