Abstract

The objective of the present work is to evaluate the effect of different doses of nitrogen combined with different doses of A. brasilense in the agronomic characteristics of wheat. The experiment was conducted in Curuguaty, Paraguay in 2017 and the variety used was Canindé 11. The experimental design is a completely randomized block with factorial ordering and four repetitions. The treatments are a combination of: three doses of N, 0, 40, 80 kg ha-1 and 4 doses of A. brasilense, 0, 700, 1000 and 1300 mg kg-1 of wheat seeds. The variables analyzed were plant height, number of spikes per plant, thousand grain weight, hectoliter weight and yield. With the exception of plant height, significant interaction between treatments was observed in all variables. Inoculation with 1300 mg kg-1 of A. brasilense associated with the application of 130 kg N ha-1 promotes the highest yields of wheat grains.

Key words: Triticum aestivum, dystrophic bacterium, winter cereal.
