“…Maize maximum TE S was estimated to be about 37 kg ha −1 mm −1 for grain yield, and 54 kg ha −1 mm −1 for total aboveground biomass. The boundary TE S for grain yield estimated here is well above reported values for winter cereals (20-22 kg grain ha −1 mm −1 ; Passioura, 2006, Sadras andAngus, 2006), grain legumes (12-20 kg grain ha −1 mm −1 ; Loss et al, 1997;Zhang et al, 2000), and oilseed crops (8-13 kg grain ha −1 mm −1 ; Specht et al, 1986;Hocking et al, 1997;Grassini et al, 2009;Dardanelli et al, 1991), which, like our maize estimates, are based on grain yields at standard commercial moisture content for each crop. Except for cases when severe water stress occurs during the sensitive anthesis-silking window (which determines maize kernel number), maize TE S for grain yield is expected to be greater than that for other crops because maize carbon fixation occurs via the C 4 pathway and the energetic cost of its grain is smaller compared to protein-rich legume seed or oilseed crops (Sinclair et al, 1984;Loomis and Connor, 1992).…”

“…Sheppard et Bates (1988) ont obtenu également des concentrations en azote plus élevées dans le grain lorsque la fertilisation en azote était accrue. D'après Hocking et al (1997), l'effet de la fertilisation azotée sur le contenu en azote du grain est cependant variable selon les sites d'essai. D'autres travaux (Dybing 1964;Freer et Sansome 1991;Diepenbrock et Pörksen 1992;Hocking et al 1997) ont démontré que le contenu en huile dans le grain diminue lorsque la fertilisation azotée augmente.…”

“…Turner (1991) a cependant obtenu des rendements en grains plus élevés avec des fertilisations azotées de 100 ou 150 kg ha -1 comparativement à une fertilisation de 50 kg N ha -1 . Toutefois, des applications d'azote élevées peuvent aussi provoquer la verse de la plante et ainsi réduire les rendements en grains (Freer et Sansome 1991;Hocking et al 1997;Grant et al 1999). …”

[2000][2001][2002]. During 2 yr, grain yields increased with higher seeding rates. However, in 2001, there was a yield reduction with the increment of the seeding rates. In 2000 and 2002, nitrogen fertilization had no effect on grain yields. In 2001, grain yields decreased as nitrogen fertilization increased. During this test, yield reduction caused by high seeding rates or nitrogen application seemed to be associated with lodging. Seeding rate and nitrogen fertilization had little effect on mineral composition of the grain. These results indicate that a seeding rate of 40 kg ha -1 and low nitrogen fertilization rates could be adequate for oilseed flax production in a cool climate.

“…Mineral N-fertilisation is a crucial factor in oilseed rape production (Dreccer et al, 2000), and together with sulphur is among the most important elements in canola production (Mirzashahi et al, 2010). Compared with cereals, canola nitrogen requirements are higher and it is considered as a high nitrogen demanding crop (Hocking et al, 1997;Rathke et al, 2005), especially when it is grown in irrigated fields (Ahmadi & Javidfar, 1998 quotes from Mirzashahi et al, 2010). For the production of 0.1 t of seeds, the whole crop accumulates approximately 6 kg of N. Therefore, the use of N source in a proper way is required so as to optimise the economic seed yield (Mason & Brennan, 1998), and also to minimise the potential risk of environmental pollution (Aufhammer et al, 1994, quotes by Karaaslan, 2008).…”

SummaryOilseed rape is one of the most important sources of vegetable oil in the world. The nutrient demand of oilseed rape is considerably higher than that of cereals. Compared to cereals, winter oilseed rape requires more available nitrogen and this element is an important component with a strong effect on seed yield and quality, but it also affects the reduction of oil content. Winter oliseed rape hybrids with high yield potential might have high nitrogen requirements. On the other hand, the vigor of those plants might also be expressed as improved nitrogen uptake by a vigorous rooting system. In many cases, N fertilisation requirement does not take into account varietal types for Brassica napus L. Furthermore, it is based on fertiliser norm, with corrections according to environmental conditions. The objective of this study was to evaluate preliminary results of the influence of nitrogen top dressing on the yield and yield components of 8 winter oil rape hybrids and 2 winter oil rape cultivars. A field trial was carried out in village Gluvo (near Skopje) in 2010/2011. The experimental design was a split-plot with 3 replications and 3 nitrogen regimes as main factors. Fertiliser treatments were: N, N+120 kg N/ha, N + 120 + 70 kg N/ha. N treatment as a base fertiliser corresponded to 70 kg of N/ha. Two ammonium nitrate dressings were broadcast, first on 25 February and then on 15 March. It can be concluded from the results we obtained that twice applied top dressing had statistically significant differences (P = 0.05) on the yield of the hybrids/varieties, number of seed/pods and length of a pod (compared to one application and without top dressing), but did not significantly influence the height of a plant and number of primary branches/plant. On a hybrid/variety level, Hybrirock (KWS), Rohan (NPZ-Lembke) and Albatros (Limagrin) may be considered as the most promising for the Skopje region.
