Abstract: Sustainable crop management relies on the combined use of organic and inorganic sources of nutrients. The experiment was laid out in a split plot design with manures (control, farmyard manure, sesbania and cluster bean) as main split and mineral fertilizer rates (control, 40-30, 60-45, 80-60, 90-70 and 120-90 kg N-P2O5 ha-1) as sub-split. The manures significantly influenced shoot dry weight, N, P and K uptake and soil properties. Conversely, the rates of mineral fertilizers did not have any effect on soil properties, however, significantly enhanced the shoot dry weight and N, P and K uptake. The combined use of manures and mineral fertilizers had a significant effect on shoot P uptake. Farmyard manure was the best manure amendment with 13% reduction in bulk density and 51% increase in organic matter content over control. Incorporation of farmyard manure increased the shoot dry weight and N, P and K uptake, respectively by 8, 14, 11 and 8% over control. Among rates of mineral fertilizers, recommended rate of mineral fertilizer (120-90 kg N-P2O5 ha-1) was the best treatment with corresponding increase of 26, 81, 56 and 55% in shoot dry weight, N, P and K uptake over control. Integration of farmyard manure with recommended rate of mineral fertilizer enhanced shoot P uptake by 17% as compared to solo application of mineral fertilizers. Through this study, it was concluded that farmyard manure at 6 tons ha-1 coupled with mineral fertilizer rate of 120-90 kg N-P2O5 ha-1 was the best source for sustainable soil health and wheat production. .
