Winter Wheat Yield

<p>Nitrogen (N) is a crop nutrient that is commonly applied as fertilizer, however the dynamic nature of N and its propensity for loss from soil‐plant systems creates a unique and challenging environment for its efficient management. Nitrification inhibitors (NIs) are compounds that can reduce the bacterial oxidation of NH<sub>4</sub><sup>+</sup> to NO<sub>2</sub><sup>−</sup> by inhibiting the activity of ammonia-oxidizing bacteria and maintaining a higher proportion of applied nitrogen in the soil by preventing nitrate loss from leaching and gaseous N losses from nitrification and denitrification. The organic compound 2-chloro-6-(tri-chloromethyl) pyridine, commonly known as nitrapyrin (NP), is such a nitrification inhibitor that is used in agriculture. The objective of this study was to investigate the effect of NI (NP) on winter wheat yield compared to farmers practice without NI at a given N rate and same number of N split applications.</p><p>A randomized complete block design in five replications was used in this study. Treatments were: T<sub>1</sub> (control treatment - without urea), T<sub>2</sub> (farmers practice - 300 kg urea/ha), and T<sub>3</sub> (urea+NP - 300 kg urea/ha). Urea was applied in three split applications at tillering, stem elongation and booting stages in treatments T<sub>2</sub> (farmers practice) and T<sub>3</sub> (urea+NP). The average grain yield of winter wheat was 8.7 t ha<sup>-1</sup> for the farmers practice (T<sub>2</sub>) and 9.1 t ha<sup>-1</sup> for the urea+NP treatment (T<sub>3</sub>) at the same number of split fertilizer applications.</p><p>The crop yield data showed that urea applied with NP (T<sub>3</sub>) did increase only slightly grain yield, as compared to farmers practice (T<sub>2</sub>). The grain yield increase with NP was about 4%, however the statistical analysis showed that this increase due to the application of urea with NP was not significant. Further research is needed to investigate additional nitrification inhibitors and their effect on wheat production.</p>

The most difficult but most informative method of determining the structure of winter wheat yield with the use of large bunches of samples is presented. The role of the stem in the formation of allthe elements of winter wheat yield structure is determined. The advantage of our method is that it allows to get deeper information about the structure of the wheat crop, as it reveals the relationship between the individual elements of the crop structure and shows the amplitude of fluctuations in individual features of thewheat crop structure. Key words: winter wheat, yield structure, stem, weight and number of grains.

The trial with different side-dressing fertilizations for winter wheat has been conducted at Vetovo site, Croatia, in vegetation seasons 2007/08 and 2008/09. The five side-dressing fertilizations has been tested (Control - no sidedressing, KAN - 100 kg KAN ha-1 in tillering and jointing stages; M1 - 8 l of foliar NPK fertilizer 'Profert Mara' ha-1; M2 - 16 l ha-1 of foliar fertilizer, and; M3 - 24 ha-1 of foliar fertilizer) at four winter wheat cultivars (Anika, Fiesta, Gabi and Rapsodija), with previously applied 400 kg NPK 7:20:30 ha-1 for all treatments. Results showed that all foliar side-dressing treatments gave winter wheat grain yield higher than the control, and that M1 treatment showed equal in comparison with KAN side-dressing. Treatments M2 and M3 had, in comparison with the control, KAN and M1 treatments, higher yields which leads toward conclusion that foliar treatments can be recommended for side-dressing for given agroecological conditions.

Winter Wheat Yield

Livestock farmers in Newfoundland presently import most of their feed grain, and local self-sufficiency in grain production is a desirable long-term goal. The overall objective of this work was to refine our understanding of winter wheat (Triticum aestivum L.) production in Newfoundland, with the aim of improving present cropping recommendations. We conducted trials near St. John's in 1998 and 1999 to examine the effect of seeding rate and topdress ammonium nitrate (N) fertilization rate on Borden winter wheat yield and yield components. We also conducted four seeding date trials in the same region. Optimum-treatment grain yields in our six trials ranged from 2.76 to 5.39 t ha−1. In years of variable winter kill, increasing seeding rate up to 450 seeds m−2 increased spikes m−2 at harvest, resulting in increased grain yield. Seeding rate, however, was not as important as N fertilization in maximizing grain yield. Increasing topdress fertilization to 60 kg N ha–1 increased spikes m–2 at harvest in years of variable winter kill, resulting in greater grain yield. In years of high winter survival, the main source of higher grain yield levels (through higher N application rates) was not achieved through greater spikes m−2 at harvest, but rather through an increase in kernel weight. Optimum grain yields occurred at seeding rates of 400 ± 50 seeds m−2, and at topdress fertilizer applications up to a rate of at least 30 kg N ha−1. Given the results of our seeding date experiments, in conjunction with previously developed climatic models, we now consider the optimum seeding date for the eastern region of Newfoundland to be August 31.
