Abstract: Experiments conducted to evaluate a compost fertilizer "Zarkhez" showed that effect of compost alone (2000 kg ha–1 and 4000 kg ha–1) on number of tillers, 1000-grain weight, yield and NPK uptake by rice and wheat was almost similar to control, whereas, significant improvements were observed when combination of compost and chemical fertilizers were applied. Maximum yield of paddy (4.25 t ha–1) and wheat (2.61 t ha–1) were obtained with 4000 kg ha–1 compost+chemical fertilizers (150-75-0 kg ha–1), which were 170.70 and 272.86 percent increased over control, respectively.
