“…Brazil significantly contribute to increase grain production in the country. Increases in wheat grain yield have been observed in recent decades, resulting from the adoption of new cultivars adapted to different environmental conditions, associated with the technified management of the production system (Caierão, Scheeren, Só e Silva, Castro, & Cargnin, 2013). Among the various cultivation techniques adopted in order to improve wheat yield, the choice of adapted cultivars stands out, as genetic characteristics directly influence the growth, development and yield of grains (R. R. Silva et al, 2011).…”

Wheat is one of the most important cereals grown in the world, and in Brazil, increasing national production is still a challenge. Nitrogen (N) supply can favor grain yield and the physiological quality of wheat seeds. However, the definition of adequate N rate and fertilization timing must consider genotype, cultivation environment, and initial seed vigor level. The aim of this work was to evaluate the effect of initial seed vigor and the combinations of rates and timings of N application on grain yield and seed physiological quality of wheat cultivars under different edaphoclimatic conditions. The experiment was carried out in Londrina and Ponta Grossa, state of Paraná, in a randomized block design in a 2 × 2 × 7 factorial scheme, with four replicates. Treatments consisted of two seed vigor levels (vigorous and non-vigorous seeds), two wheat cultivars (BRS Gralha-Azul and BRS Sabiá) and seven combinations of fertilization timings and N rates (kg ha-1) (control-0N; 20N at sowing and 60N at tillering; 40N at sowing; 80N at sowing; 40N at sowing and 40N at tillering; 40N at tillering; 80N at tillering). Number of emerged seedlings, vegetation index, shoot dry matter, number of fertile spikes m-2 and grain yield were evaluated. Additionally, the physiological potential of seeds produced in Londrina was evaluated by the testes of first count, germination, seedling emergence in sand and emergence speed index. The climatic conditions during the experiment, in both cultivation environments, were similar to average historical records, with some periods of water deficit. The highest grain yield was obtained with the BRS Gralha-Azul in Londrina, and with BRS Sabiá in Ponta Grossa. The use of vigorous seeds favored the stand establishment and the response of plants to N fertilization. The treatments 40N + 40N, and 40N + 0N favored the majority of evaluated variables. Both cultivars showed potential for the production of high physiological potential seeds in Londrina environment. Inadequate N supply impairs wheat grain yield and seed production.

“…The mean gluten strength (W) was determined at 135 x10 -4 joules, with a tenacity and extensibility ratio of 0.7 and water absorption of 58%, classifying CD 1705 in the groups of basic wheat cultivars ( Table 2). The industrial quality of wheat cultivar CD 1705 is equal to or higher than that of others already indicated for biscuit manufacturing (Franco et al 2010, Caierão et al 2013, Marchioro et al 2013, Franco et al 2016 The mean grain yield of cultivar CD 1705 in the wheat-growing regions 1, 2 and 3, respectively, were 3%, 2% and 5% higher than those of the controls (Table 3). The overall mean grain yield was 4308 kg ha -1 , exceeding the controls by 3%.…”

“…A cultivar BRS 374 alcançou os maiores valores de produtividade quando comparado a Sinuelo, embora não tenha alcançado a média de produtividade esperada, de 4.733 kg ha -1 (CAIERÃO et al, 2013). Sugere-se que a baixa produtividade verificada para as cultivares testadas neste trabalho, esteja relacionada com as condições ambientais ocorridas durante o ciclo da cultura, sendo considerado um ano atípico com temperaturas elevadas (Figura 1).…”

O objetivo deste trabalho foi determinar a dose, época e número de aplicação ideais de ácido metil salicílico (ASM) para o controle da giberela durante a antese e sua influência sobre as características agronômicas da cultura do trigo. O delineamento experimental utilizado foi de blocos casualizados, em esquema fatorial triplo 2x3x4, sendo duas cultivares de trigo, três épocas de aplicação e quatro doses, com três repetições. Avaliou-se o tamanho da espiga, peso da espiga, número de grãos por espiga, número de espiguetas estéreis por espiga, incidência e severidade de giberela, peso de mil grãos e produtividade. As variáveis analisadas foram submetidas à análise de variância e quando significativas os fatores qualitativos foram submetidas à comparação de médias pelo teste Tukey a 5% de probabilidade, e para os fatores quantitativos, realizou-se a análise de regressão. Duas aplicações de ASM, realizadas no início + ½ da antese condicionam menor número de espiguetas estéreis na cultura do trigo. A dose de 37,5 g ha-1 de ASM proporciona baixos percentuais de incidência e severidade de giberela em grãos de trigo, sugerindo inserção do ASM no manejo integrado da doença. A dose de 12,5 g ha-1 de ASM condiciona incremento na produtividade de trigo.
