Abstract
The main aim of present study was to evaluate the possibilities of composting different organic substrates i.e. crop residues, leaves of trees, vegetables and fruit wastes. Decomposed organic matter was used in rice-wheat crop production in normal soil (Organic C = 0.33%, Available P= 5.72 mu g g(-1), K= 5.7 cmol(c) L-1, pH(s)= 8.19, ECc = 2.35 dS m(-1) and SAR = 7.20). Compost (12 and 24 t ha(-1)) was applied without and with chemical fertilizer (Rice: 100-70-70 and wheat: 140-110-70 NPK ka ha(-1)) to investigate the probable effects of compost oil crop yields. The grain yield and yield components (plant height, number of fertile filters and 1000 grain weight) of rice and wheat increased significantly with the application of organic material in the form of compost at both the levels. The combination of compost with chemical fertilizer further enhanced the biomass and grain yield of both crops. This treatment proved economical over others. Oil the basis of experimental results, a recommendation for the farmers was formulated that they should compost the crop residues to apply in their soils for the increased sustainable crop production. In this way, the soil fertility call be improved with a net improvement in land productivity.
