Intervention effect Nitrogen practices significantly affected maize yield attributes and yield.
Intervention effect LCC nitrogen gave the highest cob diameter, 40.70 cm.
Intervention effect LCC nitrogen gave the highest grains per row, 29.7.
Intervention effect LCC nitrogen gave the highest ear weight, 89.0 g.
Intervention effect LCC nitrogen gave the highest grains per cob, 420.03.
Intervention effect LCC nitrogen gave the highest 100-grain weight, 20.70 g.
Intervention effect LCC nitrogen gave the highest grain yield, 4913.89 kg/ha.
Intervention effect Farmer practice gave the lowest grain yield, 3227.47 kg/ha.
Observation LCC plots had higher residual soil nitrogen, 0.15%.
Observation LCC plots had higher soil organic matter, 2.83%.
Observation LCC plots had higher available phosphorus, 11.97 kg/ha.
Observation LCC plots had higher available potassium, 142.44 kg/ha.
Observation LCC plots had reduced soil acidity, pH 5.35.
Intervention effect Tillage had no statistically significant effect on yield or soil parameters.
Recommendation The authors suggest LCC nitrogen management for long-term soil management and resource conservation.
