Nutrient Enriched Municipal Solid Waste Compost Increases Yield, Nutrient Content and Balance in Rice

Globally a huge amount of municipal solid waste (MSW) is being produced which very difficult to dispose. Composting MSW one the options recycling, but its use by farmers limited because low nutrient status. This study has considered some organic amendments increase status compost for potential as an fertilizer in rice cultivation. We prepared three types amended mixing 20% mustard oil cake (MOC) and 30% poultry manure (PM) or cow dung (CD) sugarcane press mud (SPM) with 50% compost. The inoculum Trichoderma viride was used accelerate composting process. different improved level A field experiment conducted evaluate performances composts alone combination chemical fertilizers on yield, content balance (var. BRRI dhan28). 2018 at Bangladesh Agricultural University (BAU) farm, Mymensingh having silt loam texture, pH water 6.7 2.79% matter; soil Aeric Haplaquept under order Inceptisols. There were 10 treatments consisting (urea, triple superphosphate, muriate potash, gypsum zinc sulphate) four (three unamended). Based results yield N, P, K S concentration grain, treatment containing +10 t ha−1 (MSW + MOC SPM ratio 5:2:3) performed best. apparent negative balances N (11–45 kg ha−1) (6–48 ha−1), positive P (8–71 (4–46 soils, across treatments. Results this have significant value management strategies cultivation sub-tropical countries.
