Grain yield of dual-purpose wheat cultivars as affected by nitrogen and cuttings Bragantia
Hastenpflug,Marcel; Martin,Thomas Newton; Braida,João Alfredo; Barbosa,Deivid Kelli; Zielinski,Renice Paula; Refatti,Rosana.
The aim of this work was to evaluate the effect of nitrogen fertilization and aerial part cuts on yield components, grain yield and quality of the grains for dual-purpose wheat cultivars. The experiment was carried out between May and November 2007 and the experimental design was randomized complete blocks with three replications. The main causes of variation were dual-purpose wheat cultivars (BRS Figueira, BRS Umbu, BRS Guatambu and BRS Tarumã), nitrogen doses (0, 45, 90, 135 and 180 kg ha-1) and cut systems. Each plot was subdivided by cut management (without cut, one cut and two cuts). Spike mass, number of spikelets per spike, number of grains per spikelet, grain yield and hectoliter weight were evaluated. Nitrogen fertilization did not affect the...
