Resumo

There is influence of size of the wheat seeds in the traits of importance agronomic. Thus, this study aimed to determine the effect of the size of wheat seeds in the yield components and grains productivity. The study was carried out in the 2016 harvest. Apllied is the experimental design was a randomized block, organized in factorial design, with three wheat cultivars x six seed lots x five sizes of sieves, the treatments were arranged in three replicates. Were measured characters as grain yield (kg ha-1), mass of thousand seeds (g), hectoliter mass (kg hct-1) and economic analysis obtained through profitability per hectare (R$ ha-1). The size of wheat seeds influences the number of spikelets of the principal plant, number of primary and secondary seed, number of seeds of the principal plant, primary and secondary tillers, productivity, mass of thousand seeds and hectoliter weight. The standardization of wheat seeds provides benefits to the productive yield of wheat plants. The seeds retained in the sieve V (<2.00 mm) resulted in less productive plants; and
plants derived from sieve III (2.5 to 2.99 mm) formed plants with higher productivity being 2.3% higher than
the original sample. Also, it was 2% higher than the sieve II (> 3,0 mm), 2.7% compared to sieve IV (2.0 to
2.49 mm) and 6% from sieve V (<2.0 mm).
