Observation On unamended acid soil ATP-SR-Y yielded 61% more grain than Tuxpeno Sequia.
Observation Continuous unamended maize cultivation increased soil acidity and decreased pH, calcium and magnesium while increasing aluminium.
Intervention effect Annual phosphorus application did not significantly increase grain yield of the tolerant cultivar.
Intervention effect Phosphorus application increased grain yield of the acid susceptible cultivar by 42%.
Observation Diammonium phosphate alone tended to increase soil acidity, aluminium and hydrogen and decrease calcium, magnesium and pH.
Intervention effect Lime increased grain yield of the tolerant cultivar by 82%, except in the first year.
Intervention effect Lime increased grain yield of the susceptible cultivar by 208%, except in the first year.
Association Lime associated yield gain with lower exchangeable aluminium and hydrogen and higher pH, CEC, calcium and magnesium.
Intervention effect Manure application significantly increased grain yield in both acid tolerant and susceptible cultivars.
Intervention effect Poultry manure produced 38% more grain yield than Senna leaf manure.
Intervention effect In ATP-SR-Y plots poultry manure produced a greater soil pH increase than Senna leaves.
