Abstract

The greenhouse study was carried out at Escola de Agronomia e Engenharia de Alimentos – Universidade Federal de Goiás, Brazil, to evaluate increasing levels of soil liming on Heterodera glycines population developing on soybean roots. The full dose of liming was determined in order to increase the base saturation up to 50%. The treatments were: control (no liming), half dose (0.675 t.ha-1), full dose (1.35 t.ha-1), double dose (2.7 t.ha-1), and triple dose (4.05 t.ha-1). The experimental design was completely randomized with five treatments and six replications. Each pot was planted with the cultivar FT-Cristalina and inoculated with 4,000 eggs. The number of H. glycines females on soybean roots, and cysts/100 cm3 were evaluated. The number of females was reduced as liming doses increased up to 3.03 t.ha-1, showing quadratic response. The number of cysts reduced linearly as liming doses were reduced.
