Treatments to supply 1, 2, 3, or 4 t ha-1 of cowdung alone, 2 t ha-1 Cassia spectabilis alone and 2 t ha-1 C. spectabilis in combination with 1,2, 3, or 4 t ba-1 cowdung were applied to a Clayey Kaolinitic Typic Haplustox at Misamfu. A grass mound was used as a control. A randomized complete block design with 4 replications was used. Maize (MMV 400) was the test crop. Soil samples collected at the beginning and end of the study were analyzed for pH, organic C, total available P, exchangeable K, Ca, Mg and Na. Plant height, dry matter, grain yield and nutrient uptake were assessed. Results showed significant increases in plant height (65%, 59% and 13%) at 3 growth stages with 99% grain yield increase over the control due to increased N (126.6%), K, Mg uptake in treatments receiving Cassia + cowdung. In these treatments, soil C/N ratios decreased by 5.5% while N and P concentrations increased by 33.3 % and 10.4 % respectively, across all treatments. The study suggests the need for using animal and plant manures together to improve maize nutrition.Collection: CIMMYT Publications Collection
