Aplicação de cálcio e silício na produção e qualidade de sementes de soja

Abstract

The use of natural products on the protection plants is an important tool for the farmer. Therefore, this work aimed evaluate the efficiency of different treatments (control; calcium 40 and 50kgha-1 ; silicon 40 e 50kgha-1) to increase of production and improve the quality of soybean seeds. The components of the production evaluated were: production per plant, grain yield, number of pods per plant, number of seeds per pod and weight of 1000 grains. Also, were evaluated laboratory tests as: germination and vigor (first count of germination, cold test, accelerated aging, electrical conductivity and tetrazolium). According to the results, concluded that soybean plants treated whit calcium and silicon produce seeds of higher physiological quality; the treatments reduces the seed yield per unity of area.
