“…The optimization of scientific farming measures as well as water supply, fertilizer and pesticide application are very important in achieving a significant increase in values for grain yield and grain yield components (Jolánkai et al, 2006). Also, it is important to estimate the level of genotype adaptation to limiting environmental factors, and assess the ability of genotype to make use of favorable environmental factors (Kovačević, 2007).…”

three experimental years under different environmental factors. The experiment was set up as a randomized block design in three replications. Differences in the average values of grain weight spike-1 among tested cultivars were determined in all three years. On average, for all genotypes, grain weight spike-1 was highest (2.32g) in the first experimental year (2005/06), and lowest (1.95g) in the second year (2006/07). For all investigated wheat cultivars, in the third experimental year, the average value of grain weight spike-1 was 2.24g, while the total average value for all cultivars and three experimental years was 2.17g. 'Ana Morava' had the highest average values for grain weight spike-1 in all three experimental years, while the lowest grain weight spike-1 was obtained in 'Balkan' (1.81g) in the second year 'Lasta' (1.40g) and in the third experimental year 'Partizanka' (1.91g). On average, 'Ana Morava' had the

“…Wheat grain yield and yield components varied in dependence of crop nutrition, pest protection (Jolánkai et al, 2006) weediness and meteorological conditions (Márton, 2008). For achievement of high grain yield and quality it is necessary to optimize scientific farming measure like soil tillage (Sepp et al, 2009), optimal time and density of sowing (Petrović et al, 2008), level of water (Pawlonka & Skrzyczyńska, 2004), fertilizer pesticide application (Füleky, 2008).…”

“…Grain yield and yield components and protein content increased with increasing NP fertilizer rates (Zečević et al, 2012). The increasing of nitrogen rate resulted in increasing of biomass formation both of cereal plants and weeds (Jolánkai et al, 2006;Knežević et al, 2007).…”

In this study we tested yield and weediness in wheat cultivars Lazarica and Julija Mono grown under different regime of mineral nutrition. This investigation was conducted at the long term experiment on control variant (without fertilizers), second variant with nitrogen application (two sub variants with different rate of N) 2N 1 (80 kg N ha -1 ) and 2N 2 (120 kg N ha -1 ), third variant with NP fertilizer with two different rate of N application: 3N 1 (80 kg N ha -1 + 100kg P ha -1 ) and 3N 2 (120 kg N ha -1 + 100kg P ha -1 ) and fourth variant 4N 1 (80 kg N ha -1 + 60kg P ha -1 ) and 4N 2 (120 kg N ha -1 + 60kg P ha -1 ). Weediness varies in dependence of rate and variant of fertilization. The weed species Consolida regalis Gray, Convolvulus arvensis L., Polygonum aviculare L., Cirsium arvense L., Agropyrum repens L., Polygonum convolvulus L. was dominant on fertilized plots. The analyzed variability of grain yield depends of applied fertilizer variants. The lowest grain yield was found on control variant in both wheat cultivar Lazatica (1880kg ha -1 ), Julija Mono (1740kg ha -1 ) while the highest grain yield on variant 3N 2 (120 kg N ha -1 + 100kg P ha -1 ) Lazarica (3724kg ha -1 Julija Mono (4990kg ha -1 ) and low weediness.

“…One of the most cardinal elements of wheat production is the seeds, as not only their quantity but the quality is very important, therefore seeds must be produced at the highest level as possible (Jolánkai et al, 2006). The main goal of seed production is to gain high quality seeds demanded by the market economically.…”

Effects of fertilization on some quantitative and qualitative characteristics of winter wheat in Great Cumania

Due to the drastically increasing food prices during the last few years in Europe and also in Hungary, good and medium quality winter wheat varieties produced at low costs with high yield potential came to the front. Although food overproduction is characteristic to one part, while shortage of food to the other part of the world, the newest tendencies show an increasing role of the production and consumption of high quality food that can be produced only from high quality raw materials. When a new variety is certified, the qualitative parameters are more and more important beyond the quantitative ones. Several programmes were started to breed and produce winter wheat varieties with excellent qualitative parameters including the determination of the adequate, variety-and habitat specific agrotechniques and plant nutrition. In Karcag Research Institute plant breeding and long-term fertilization experiments have been carried out separately from one another for several decades. In the vegetation period of 2012/2013 a new series of experiments was started that includes the determination of the fertilizer doses optimal for our high quality winter wheat varieties with high yield potential. The determination of the adequate and optimal fertilizer doses are essential not only from economic point of view and lower environmental loads, but also for the most effective utilization of the genetic potential of our winter wheat varieties without the degradation of the qualitative parameters. After the assessment of the data we established that extreme high doses of fertilizers are needed for the spectacular improvement of the parameters we examined. As the financial possibilities of farmers are limited, the fertilizer cost is a determining factor: they have to consider if the yield or the quality of a given variety can be increased at an affordable fertilizer input. Our goal is to determine the often empiric hence not so accurate fertilizer doses more precisely providing the producers a proper production technology and plant nutrition recipe adequate to the varieties bred by us. Due to the complexity of this topic high number of further examinations is required.
