Intervention effect pendimethalin significantly reduced grassy weed population.
Intervention effect atrazine significantly reduced grassy weed population.
Intervention effect Pre-emergence atrazine gave the maximum 69% reduction in grass weed population at 20 DAS.
Observation Tembotrione alone controlled grasses and broad-leaved weeds.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced weed biomass of 2.9 g/m2.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced weed biomass of 7.5 g/m2.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced weed dry matter of 98.7%.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced weed dry matter of 97.9%.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced grain yields of 11.57 t/ha.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced net returns of ‘ 74210/ha.
Intervention effect Atrazine as pre-emergence followed by (fb) tembotrione + atrazine as post-emergence produced B: C ratio of 2.73.
Association Weed biomass at 60 DAS was negatively correlated with maize grain yield and accounted for 55% of yield variation.
