This work was carried out with peanut seeds, cv.?Tatu?, in a randomized block
design with three replications with aimed in the evaluate physical and physiological qualities of
peanut seed from plants cultivated with various phosphogypsum sources, combined with application
time and method no limed area. The treatments were of phosphogypsum rates (zero, 400, 800,
1200kg/ha), application times at sowing or flowering and application method (total area or in
furrows). Sowing fertilization consisted of phosphorus (80kg/ha of P2O5) and potassium (30kg/ha
of K2O). Seed quality was evaluated by weight of 100 seeds, germination, vigor (first germination
counting, accelerated aging, eletric conductivity and field seedling emergence) tests and evaluation
of macronutrient levels in seeds. Phosphogypsum, independently of rate, application time and
application method, was benefical for the seed quality. The phosphogypsum application at total
area was uppermost benefical for the seed quality at application in furrows. The phosphogypsum
sources in function application method influence the seed content of N, K and Mg. The fertilization
with P and K highed the seed contents of N and P.
