Intervention effect Ripper tillage gave the highest maize yield of 10.37 t ha-1
Intervention effect Moldboard plowing gave a lower maize yield of 10.22 t ha-1 than ripper tillage
Intervention effect Strip tillage gave a lower maize yield of 9.60 t ha-1 than ripper tillage
Intervention effect Ripper tillage and moldboard plowing gave no significant yield difference
Intervention effect Ripper tillage and moldboard plowing gave significantly higher yield than strip tillage
Association Maize yield variation was higher in non-fertilised tillage plots than in fertilised plots
Association Tillage and fertilisation interacted positively for maize yield
Intervention effect Fertilizer application increased maize yield
Association Fertilizer application accounted for 43% of maize yield variance
Intervention effect N160 kg ha-1 gave the highest maize yield of 11.88 t ha-1
Intervention effect N80 kg ha-1 gave a maize yield of 10.83 t ha-1, below N160 kg ha-1
Intervention effect Non-fertilised plots gave the lowest maize yield of 7.48 t ha-1
Association Loupiac (FAO 380) gave a higher yield of 11.09 t ha-1 than Armagnac (FAO 490)
Association The yield difference between the two hybrids was almost constant in both years
Association Yield varied strongly between 2015 and 2016 with a highly significant year effect
