“…This is why plants in grain-only systems are more likely to escape damage from hot winds, drought, and rust, which normally are experienced during later growing stages of wheat and barley in this region. Other researchers have found similar results about delaying in phenological development of cereals as a consequence of forage removal (Royo et al, 1997;Tian et al, 2012;Virgona et al, 2006). The extent of delay in crop phenology was dependent on the time of forage removal; cutting or grazing before stem elongation (GS30) resulted in only small delays (0-5 d) in crop phenology (Tian et al, 2012;Virgona et al, 2006), whereas defoliation at later growth stages resulted in greater delays (Royo et al, 1997).…”

Nitrogen Fertilizer and Seeding Rate Influence on Grain and Forage Yield of Dual‐Purpose Barley

Clipping fall-sown cereals provides a good source of high-quality forage during late winter. Farmers usually use more inputs, including fertilizers and seed, in dual-purpose systems compared with grain-only systems. A 2-yr fi eld study was conducted in Karaj, Iran, to evaluate the eff ects of nitrogen (N) rates (0, 50, 100, 150 kg N ha -1 ) and seeding rates (400, 600, 800 seed m -2 ) on forage and grain yields of two barley (Hordeum vulgare L.) cultivars (Fasih and CB 744) in grain-only and dual-purpose systems. Fasih and CB 744 grain yields in the grain-only system were 2996 and 3250 kg ha -1 , respectively (averaged over experimental treatments). Forage removal in the dual-purpose system resulted in 25% grain yield penalty. Despite the lower grain yield, the economic return of the dual-purpose system was considerably greater due to the high price of forage during late winter in the region. Grain yield response to N was linear in the grain-only system, but the trend was not signifi cant in the dual-purpose system. In both production systems, grain yield response to seeding rate was quadratic, and the highest yields of both cultivars (2534 and 3192 kg ha -1 for Fasih and CB 744, respectively) were obtained from 600 seed m -2 . In both production systems, 600 seed m -2 and 100 kg N ha -1 were optimum for grain and forage production. Our results showed considerably higher revenue in the dual-purpose system compared with the grain-only system in this region. Moreover, no additional inputs of N and seed are required for dual-purpose barley than those usually used in a grain-only system.

“…C H E N et al shoot production and forage quality in both wall barley (El-Shatnawi et al, 1999, 2003 and barley (Birhan, 2013;Jenkyn and Anilkumar, 1990). The capacity for re-growth of barley after defoliation enables it to be used as both forage and grain (Royo et al, 1997). Most of the previous reports are concentrated on the impacts of defoliation pattern and defoliation frequency on the re-growth of barley (Jebbouj and Yousfi, 2009) and the effects of sowing dates and cutting stages on forage yield and quality and grain yield (GY) (Royo, 1999;Royo et al, 1997).…”

DEFOLIATION ENHANCES GREEN FORAGE PERFORMANCE BUT INHIBITS GRAIN YIELD IN BARLEY (HORDEUM VULGARE L.)

SUMMARYTo evaluate the effects of defoliation on green forage performance and grain yield (GY) variation in barley, five barley genotypes were imposed on three levels of defoliation treatments over two consecutive growing seasons in this study. The results indicated that green forage yields were significantly improved by repeated defoliation. The traits of green forage quality, including the ratio of dry weight to fresh weight, crude ash and calcium content were improved, while crude protein and crude fat were reduced, and crude fiber and phosphorus contents appeared not to be influenced by repeated defoliation. Plant height (PH), GY and other yield components, grain number per spike and thousand kernel weight, were significantly reduced by defoliation over the two growing seasons, while internode length below spike was less affected. Reduction in spike length and the number of spikes per plant were identified in only one year. Correlation analysis revealed that only PH exhibited a positive correlation with GY. Effects of genotype, interaction between genotype and defoliation, and environments on changes of forage yield and quality and GY were also discussed. Our current work provides a feasible approach to select elite barley cultivars with optimal defoliation treatments for both forage and grain uses in barley breeding programme.

“…El rendimiento de los cultivos doble propósito, tanto en producción de forraje como de grano, está limitado por las condiciones ambientales, fundamentalmente precipitación pluvial, temperatura y disponibilidad de nutrientes en el suelo. Trabajos realizados en cultivos doble propósito mencionan reducciones en la producción de grano para cosecha (Redmon et al, 1996;Royo et al, 1993Royo et al, , 1997Francia et al, 2006;Harrison et al, 2012), siendo de diferente magnitud según el cultivo, las condiciones climáticas, la fecha de siembra, el momento de pastoreo, entre otros. En nuestro país, los rendimientos de un ensayo realizado en el SO de Buenos Aires oscilaron entre 1.000 a 2.800 kg.ha -1 para avena doble propósito y entre 2800 a 6050 kg.ha -1 para grano (Wehrhahne, 2005 La preparación del suelo consistió en una labranza convencional mediante disco, rastra y rolo.…”

“…En ese trabajo, los autores encontraron que la disminución en el número de granos.m -2 en avena luego de dos cortes de biomasa, fue la razón principal de la caída en el rendimiento (13.000 granos.m -2 vs 8.571 granos.m -2 ). Royo et al (1997) expresaron que el NGP fue el componente del rendimiento más afectado en otros cultivos doble propósito como cebada y triticale, después de los cortes de biomasa. Sin embargo, Bonachela et al (1995) señalaron que las reducciones en el rendimiento de cebada y triticale doble propósito, se explicaron por disminuciones en ambos componentes del rendimiento (granos.m -2 y PMG).…”
