“…In addition to temperature and sowing date, sufficient water availability is the critical factor for adequate tillering in spring barley (Svobodová and Míša 2004). Higher formation of tillers and their lower mortality may be supported also by timely nitrogen nutrition (Baethgen et al 1995).…”

Timely and reliable prediction of grain yield and quality of spring barley represents a key prerequisite for effective crop management. Within this study we evaluated the relationships between yield components, grain quality, biomass production and the number of tillers in different growth stages. For this purpose, in three years (2011)(2012)(2013) multifactorial field trials focused on the combined effects of cultivar, sowing density and nitrogen nutrition were conducted. Based on ANOVA it was found that the formation of grain yield was affected by individual factors in the following order of importance: year, nitrogen, cultivar and sowing rate. The final grain yield significantly correlated both with the number of tillers and dry weight of above-ground biomass per unit area. The best estimation of yield provided both parameters at early growth stage (R = 0.83** and 0.81** for number of tillers and the above-ground biomass at BBCH 25). The grain protein content was inversely related to early growth parameters (R = -0.64** and -0.41** for number of tillers and above-ground biomass at BBCH 25). Based on the comparison of relationships between the years, it can be concluded that the early growth of barley and tiller differentiation is a key parameter for the formation of yield and grain quality.

“…Uptake of soil N is moderate during the first phases of crop growth, but continues up to harvest and is maximum during anthesis (McTaggart and Smith, 1995). According to Baethgen et al (1995), relatively small amounts of available nitrogen must be ensured for the establishment of the barley crop and the initial development of tillering. The additional N could be applied at the end of this period.…”

A field study was conducted from 1998 to 2000 in Ciudad Real (Spain) to analyze the productive response of thebarley (Hordeum vulgare L.) crop to different nitrogen-fertilizer strategies. The effect of N dose and its partitioningbetween sowing-time and top-dressing at tillering state on grain yield and yield components was evaluated, as well asthe contribution of each one of these parameters to the final yield by means of a correlation and regression study, andpath coefficient analysis. The specific climatic conditions of each growing season had a very marked effect on barleycrops, and grain yields and yield components significantly differed every year. No significant differences in yieldwere found between 100 and 150 kg N ha-1 doses, but yield was significantly reduced by applying 200 kg N ha-1. Theevolution of grain yield according to N fertilizer was properly fitted to a quadratic function, with the maximum valuecorresponding to about 120 kg N ha-1. It is not advisable to exceed this dose because this is of no benefit to the plantand implies a risk of environmental contamination. The highest yield was obtained by applying two thirds of the totalN fertilizer at seeding time, whereas a single application of N fertilizer as a top-dressing resulted in a significantreduction in barley grain yield. In these field conditions, grain yield mainly depended on the number of ears per squaremeter, being the 1000-kernel weight the most stable yield component.

“…Th is is because of the diffi culty associated with trying to balance maximum yields with relatively low levels of protein. Limiting N application at sowing with additional applications at the end of tillering based on the requirements of the crop has been suggested as a way of addressing this dilemma (Baethgen et al, 1995). However, this approach may be more feasible in regions with longer growing seasons and more consistent precipitation than the Canadian prairies.…”

The malting barley (Hordeum vulgare L.) industry is often challenged by the availability of sufficient volume and quality to meet demand. Our objective was to evaluate the effects of agronomic practices on grain uniformity, protein concentration, yield, and yield components. Field experiments were conducted from 2005 to 2008 at eight rain‐fed locations in western Canada. The effects of two seeding rates (200 and 400 seeds m−2) and five N (0, 30, 60, 90, and 120 kg ha−1) rates on two two‐row barley cultivars (‘AC Metcalfe’ and ‘CDC Copeland’) were determined. Each experiment was conducted for 3 yr at each location (24 environments). CDC Copeland displayed some advantages over AC Metcalfe including higher grain yield, lower protein and more uniform kernels. For both cultivars, kernel weight, and plumpness were lower at the higher seeding rate; protein was also lower, maturity was earlier and kernels were more uniform. With increasing N rate, barley yield, kernel weight, and tillers plant−1 increased, but days to seed maturity and protein concentration also increased, and kernel plumpness and seed uniformity decreased. The increase in protein was less pronounced with CDC Copeland suggesting that there may be less risk with this cultivar of unacceptable protein levels at relatively high N rates. At many environments barley plant stand decreased while lodging increased with increasing N rates. To improve the likelihood that barley will be acceptable for malting growers should select low‐protein varieties, seed at relatively high rates and limit N application.
