“…The winter wheat production in the southern Great Plains including Texas, Oklahoma, and southern Kansas has been managed for one of the three purposes (Carver et al 2001;Redmond et al 1995;True et al 2001): (1) for grain only, (2) for forage only, or (3) for both forage and grain (dual-purpose). In the case of rye, it is mainly cultivated for forage in the southern Great Plains (Ball et al 2001;Bowman et al 2008).…”

“…Winter wheat breeding programs in the southern Great Plains also have traditionally developed varieties with high grainyield and quality suitable for planting in midOctober (Arzadún et al 2006;Carver et al 1991Carver et al , 2001Winter and Thompson 1990). Atkins et al (1969) emphasized that forage characteristics should be considered during wheat cultivar development because forage and grain yield were different traits and did not have a positive association.…”

Wheat (Triticum aestivum L.) has been widely grown as a winter forage crop in the southern Great Plains. However, development of wheat cultivars for winter forage production has not been a major goal of wheat breeding programs in the USA. Also, little information on forage yield and nutritive value of currently grown wheat varieties is available. The objective of this study was to test 15 wheat varieties to compare their forage yield and nutritive value and to identity superior varieties for winter forage production. The field trials were conducted during three growing seasons in southern Oklahoma. There were significant effects of variety, clipping-date, and environment for mean forage yield. The mean forage yield of the varieties ranged from 2,200 kg ha -1 for NF95134A to 1,655 kg ha -1 for Forage Max. The crude protein content varied from 24.2 to 20.8 %. When mean forage yield and crude protein yield were considered, NF95134A was the best variety for the tested regions. However, when low detergent fiber content and high energy value were considered, Forage Max was the best variety in the tested environments. When forage production, especially during the coldest months December through February was considered, NF96107A and NF96131 produced the best forage yield. This study showed that significant differences in forage yield and nutritive value existed among the winter wheat varieties and the results of the study could provide useful guidelines for livestock producers and for forage wheat breeding programs.

“…According to Carver et al (2001), in some years, more than 50% of the winter wheat acreage in the southern Great Plains of the United States is used for the dual-purpose of grazing stocker cattle and harvesting grain. However, in Brazil, less than 1% of the wheat production area is planted with dual-purpose cultivars (Companhia Nacional de Abastecimento, 2010).…”

-The objective of this work was to evaluate the influence of different grazing periods on beef animal production and on wheat forage and grain yield. The experiment was carried out in Pato Branco, PR, Brazil. Six grazing periods were evaluated (0, 21, 42, 63, 84, and 105 days) on dual-purpose wheat cultivar BRS Tarumã. Purunã steers, with average live weight of 162 kg and ten months of age, were kept under continuous grazing using a variable stocking rate, in order to maintain the established sward height of 25 cm. Greater increases in total animal gain (TAG) occurred with longer grazing periods. However, there was little increase after 63 days (490 kg ha -1 ), and TAG decreased from 552 to 448 kg ha -1 between 84 and 105 days. Grain yield decreased from 2,830 to 610 kg ha -1 when the grazing period increased from 0 to 105 days, but there was little change after 63 days (750 kg ha -1 ). Cultivar BRS Tarumã shows excellent animal production potential, and the decision on how long wheat pastures should be grazed must be based on relative prices of grain and livestock.Index terms: Triticum aestivum, 'BRS Tarumã', forage mass, nutritive value, Purunã steers, weight gain. Produção animal e de grãos de trigo duplo propósito em diferentes períodos de pastejoResumo -O objetivo deste trabalho foi avaliar a influência de diferentes períodos de pastejo na produção de carne bovina, de forragem e de grãos de trigo. O experimento foi conduzido em Pato Branco, PR. Foram avaliados seis períodos de pastejo (0, 21, 42, 63, 84 e 105 dias) com a cultivar de trigo de duplo propósito BRS Tarumã. Novilhos Purunã, com peso vivo médio de 162 kg e idade de dez meses, foram mantidos em pastejo contínuo, com taxa de lotação variável, para manter a altura de pastejo estabelecida de 25 cm. Maior ganho animal por área (GA) foi encontrado em períodos mais longos de pastejo. No entanto, houve pouca diferença após 63 dias (490 kg ha -1 ), e o GA diminuiu de 552 para 448 kg ha -1 , entre 84 e 105 dias. A produtividade de grãos diminuiu de 2.830 para 610 kg ha -1 com o aumento do período de pastejo de 0 para 105 dias, mas mudou pouco após 63 dias (750 kg ha -1 ). A cultivar BRS Tarumã apresenta excelente potencial para a produção animal, e a decisão quanto ao período de utilização do trigo para pastejo deve ser baseada nos preços relativos de grãos e dos animais.Termos para indexação: Triticum aestivum, 'BRS Tarumã', massa de forragem, valor nutritivo, novilhos Purunã, ganho de peso.

“…A net reduction of 23 and 48% in grain yield due to forage removal has been previously reported by Khalil et al (2002Khalil et al ( , 2008. However, these losses in grain yield can be minimized by applying better management practices, such as optimum date of planting, appropriate stage of clipping and applying N fertilizer after forage clipping (Carver et al, 2001).…”

ABSTRACT. Farmers in northern parts of Pakistan face severe shortage of green forage for their livestock during the harsh winter season. Winter wheat has the potential to be used as a dual-purpose crop for forage plus grain production in these areas. Ten elite winter wheat lines from Oklahoma State University were evaluated at Hazara Research Station Abbottabad under unclipped and clipped treatment level during 2005-06. The material was planted in a randomized complete block design with three replications, with a row length of four meters and a row to row space of 25 cm. Data were recorded on green forage yield, plant height, spike length, spikelets/spike, days to maturity, spike weight, biological weight, and grain yield. Analysis of variance indicated significant differences among genotypes for all traits except spike length. Similarly all traits except spikelets/spike exhibited significant differences between unclipped and clipped treatment levels. Genotype x clipping interaction was non-significant for all traits except grain yield. Overall, winter wheat lines OK98G508W and OK00611W performed better for important traits such as early maturity, biological yield and grain yield, although over-environment testing is needed before recommendations can be made to the farmers.
