Abstract

The aimed to evaluate the effect of different nitrogen doses in association with sulfur fertilization on yield components and seeds physic-quality attributes. The experimental design was randomized blocks, arranged in a 3 × 5 × 2 factorial design (cultivar × nitrogen doses × sulfur management), with four replications. The analysis of variance revealed that wheat cultivars × sulfur management interaction was significant for height insert of main spike. Interaction was verified between cultivars × nitrogen doses for number of tillers per plant and number of spikes per m2. The nitrogen doses × sulfur management interaction was significant for number of tillers per plant. Interaction between cultivars × nitrogen doses were observed for number of spicules per spikes and number of seeds per spike. Nitrogen fertilization has different effects on wheat cultivars. The cultivar ‘TBIO Sinuelo’ presents greater seeds yield with improvement of nitrogen fertilization doses. High nitrogen doses provide increasing of wheat seeds yield. Nitrogen doses influence differently on yield components of wheat. Number of tillers per plant is correlated with seeds yield. Physical attributes of wheat seeds are not influenced by nitrogen doses increasing. Sulfur fertilization promotes tillering and increment of number of spicules per spike. The cultivar ‘TBIO Sinuelo’ presents higher weight per 1000 seeds, followed by ‘Jadeíte 11’, and ‘TBIO Sintonia’.
