Observation Sunflower biometric and performance indicators changed with density and biofertilizer.
Observation Height was greatest at 60 thousand/ha for the six sunflower hybrids.
Observation Leaf area per plant decreased as density rose from 40 to 80 thousand/ha.
Observation Leaf area per hectare was greatest at 60 thousand/ha.
Observation Thickening stands reduced 1000 seed mass across sunflower hybrids.
Observation The largest 1000 seed mass occurred with seed dressing at 40 thousand/ha.
Observation Seed treatment raised 1000 seed mass by 0.1-0.4 g.
Observation Yield was highest at 60 thousand/ha with seed pretreatment; Site reached 2.09 t/ha.
Observation Site was the most productive sunflower hybrid.
Observation Biofertilizer raised yield, with the largest increase at 60 thousand/ha.
Observation Biological fertilizer had no significant effect on seed fat content.
Observation Oil yield peaked at 60 thousand/ha with seed treatment.
