Abstract:
This trial aimed on determining soybean seeds quality in an organic production
under two management systems: no tillage and reduced tillage (scarification + grading) in western
region of Paraná State. Six treatments were designed to control some plagues plus one check
treatment) (1 Baculovirus anticarsia; 2 Baculovirus anticarsia + cinnamon extract; 3 cinnamon
extract; 4 Baculovirus thurigiensis; 5 Neen oil; 6 Compost A; 7 check treatment. Parameters as
water content, weight of one hundred seeds, seedling percentage, seeds vigor determined by fast
aging and seeds yield were evaluated. The data were analyzed by Scott Knott test – 5 % of
significance – which allowed to conclude that the high level of seeds’ deterioration, derived from
the low efficiency of treatments, contributed to the decreased seed quality. However, Compost A
treatment presented the best response regarding to yield.
