    A screen house and field trial was carried out on two varieties of jute mallow (Oniyaya and Amugbadu) at Araromi Ilorin Kwara State and National Centre for Agricultural Mechanization (NCAM) respectively during 2022 cropping season to compare the effect of coated urea inhibitor and poultry manure on soil chemical properties, growth and yield of jute mallow. Five treatments were used for both field and pot experiments. The treatments comprised of control, urea, NPK, urea inhibitor, poultry manure at 45 kg N/ha each replicated three times and fitted into a completely randomized design (CRD). Field experiment was a randomized complete block design with three replicates. All fertilizers used significantly enhanced the growth and dry matter yield of varieties of jute mallow under screen house investigation. In the field study jute mallow yield values of Oniyaya and Amugbadu were 3.8 and 3.6 t ha-1 respectively with poultry manure and these were significantly (p< 0.05) higher than that of urea inhibitor treatment (2.6 and 3.5 t ha-1) after the first cropping. Residual effect of jute mallow yield values obtained from poultry manure was also significantly (p< 0.05) higher than that of urea inhibitor values. Poultry manure at 45 kg N ha-1 had a significant and additive effect on soil nutrients after harvesting of the two varieties of jute mallow when compared with urea inhibitor in first and second cropping. Therefore, it can be deduced that application of poultry manure at 45 kg N ha-1increased soil productivity and led to higher jute mallow varieties yield than using urea inhibitor.
