The effect of cow dung, poultry droppings, organo-mineral and NPK 15:15:15 on the soil chemical properties and their effectiveness as sources of nutrients for “Celosia argentea” were investigated. The investigation was carried out in a field experiment laid out in a randomized complete block design (RCBD) with three replicates. Before planting and at crop maturity, surface soil samples were collected from the experimental site using soil auger. The soil samples were bulked, air-dried, passed through a 2mm sieve and analyzed. Measurements of agronomic characters were taken and data collected were subjected to analysis of variance (ANOVA) using the statistical analysis system (SAS). Increase in soil organic matter, nitrogen, potassium, calcium, sodium and magnesium was observed after harvest in soils treated with organo-mineral fertilizer, poultry manure and cow dung. The fertility status of the soil treated with NPK 15:15:15 was found to be low. Though all four fertilizer types were found to increase the size of agronomic characters, the effect of NPK 15:15:15 was more prominent. However, poultry manure or organo-mineral fertilizer could be used to grow “C. argentea” where NPK 15:15:15 is beyond reach.
