Experiment was carried out under the glasshouse at the Faculty of Agriculture, Khon Kaen University. It was conducted to determine the effect of poultry manure application on growth of papaya plants in an acid Yasothon soil. Manure at the rates of 0, 50, 100 and 150 gm/pot were mixed the soil. The results indicated that dry matter of papaya plants were significantly increased by the application of poultry manure. The addition of poultry manure resulted in a marked increase in N and K uptake in plant tops. The N and K concentration in plant tops were very high in comparison with the Ca and Mg concentration. The Organic matter, Total N, Exchangeables K, Ca and Mg content in this soil were significantly increased with increasing the rates of poultry manure. The optimum rate of poultry manure application in this soil was 50 gm/pot.
