Quality and production of soybean seeds in no tillage and reduced tillage soil systems - DOI: 10.4025/actasciagron.v28i1.1676

Abstract

This trial aimed at determining soybean seeds quality in an organic production under two soil management systems: no tillage and reduced tillage (scarification + grading) in western region of the State of Paraná. Six treatments were designed to control some weeds plus one check treatment) (1.Baculovirus anticarsia; 2.Baculovirus anticarsia + cinnamon extract; 3.Cinnamon extract; 4.Baculovirus thurigiensis; 5.Neen oil; 6.Composite A; 7.Check treatment. Parameters as water content, weight of one hundred seeds, seedling percentage, seeds vigor determined by fast aging, triphenyl tetrazolium chloride and seedling yield were evaluated. The data were analyzed by the Scott Knott test – 5% of significance – which allowed to conclude that the high level of seedling deterioration, derived from the low efficiency of treatments, contributed to the decreased seed quality. However, the soil tillage system did not influence the seedling profit and the Composite A treatment responded better in relation to yield.
