City Waste Compost and Sustainability of Rice-Wheat Cropping System
Keywords:Organic manure, plant nutrients, sustainability
AbstractAn experiment was conducted on Rhodic Ustochrept soil in Central Hill of Nepal growing
wheat-mungbean-rice in rotation. Grain yields as affected by 28 t ha-1 a of town compost were
compared with the same amount of farmyard manure and N:P:K (120:60:40). NPK produced
significantly higher wheat grain (3897 t ha-1). Other yield results were at par with one another.
NPK produced lowest mungbean yield. After growing second crop fertility seems to be
exhausted thus rice yield indicated no notable residual fertilising effect. FYM and town compost
left noteworthy amounts of P, Ca, Mg and K even after rice harvest.
Key words: Organic manure; plant nutrients; sustainability
