Farming systems and nutrient integration effect on soil nutrient dynamics and yield of maize

Experiments were conducted to examine soil nutrient dynamics under different farming systems and sources on maize yield. It was a split plot fitted into RCBD with three replicates. Main plots included two cropping (CS) (maize groundnut fallow): sub-plots; residue (GNR), (MZR), Cow dung (CD), pig manure (PGM); four composts; (PGM+MZR, PGM+GNR, CD+GNR CD+MZR) each at 5 t/ha; NPK 120 kg/ha, (Co) control. Nutrient content of the measured fallow (GF) continuous system (CMCS), yield harvest. Data collected subjected analysis variance means separated by Duncan Multiple Range Test 5% probability level. The CS impacted dynamics, increased 31.25% N, 8.25% P 35.45% K from GF reduction 33.33% N 19.35% but increase 3.98% in CMCS.
