The researches were done in the field conditions using three winter wheat varieties and seven ways of seed protection. Varieties are different according to the tillering type, stalk height, leaves' position, length of growing season, genetic potential for yield and grain quality, and they are PKB-Kristina, Pobeda and Vizija. Variety trial was set up in test field of "Tamis" Institute (2003/04 - 2005/06) in Pancevo using split-plot method with four protection variants with fungicide, plus electronic protection of plasma electrons with positive and negative control. It was determined that the way of seed protection was the factor that has a significant impact on the grain yield. Vizija variety had lower grain yield (6.59 t/ha{cyrillic}) than Pobeda variety (7.02 t/ha) and PKB-Kristina variety (7.07 t/ ha). The difference is highly significant. Comparing the yield from the aspect of the applied way of protection, highly significant difference between the control (6.61 t/ha) and variants, being treated by diviconazole, difeconazole, carboxine + tiran and tebuconazole + triazoxine, was proven. Significant difference was not established between variants being treated by diviconazole and difeconazole, whereas significantly lower yield than they had, had the treatment with ed carboxine + tiran and tebuconazole + triazoxine. Significant difference was not establish between them. Treatment with electronic way of protection of plasma electrons showed significantly lower grain yield than the protection with fungicides and it is controlled. In the case of all tested variants, where seed protection was done, significant difference concerning grain yield in comparison to control, was established. Highly significant difference was established between the years when the research was done as well as variety x year interaction.

Percent of four seed fractions (2.0 mm, 2.2 mm, 2.5 mm and 2.8 mm) was examined in six locations in the period from 2002 to 2005 for fourteen wheat varieties made in Serbia. Proportion of location variance was higher in the case of genotypic variance and genotype x location interaction variance. Location variance amounting 53.5 % was the lowest in the case of 2.0 mm-seed-size and the highest one amounting 73.5 % in the case of 2.8 mm-seed-size. Contrary to this, genetic variance and genotype x location interaction variance were higher in the cases of smaller seed fractions (2.0 and 2.2 mm) comparing to 2.5 and 2.8 mm-seed-sizes. Larger seed fractions of 2.5 and 2.8 mm-seedsizes are the most significant in the seed production of wheat. Percent of 2.8 mm-seed-size in the examined locations was as follows: CA>SM>ZA>SO>PA>KI. "11" variety realized the highest seed content of 2.8 mm-seed-size in the ZA, PA, SM and CA environments. The highest proportion of 2.8 mm-seed-size fraction had "14" and "8" varieties in the SO and KI locations. Average percent of 2.5 mm-seed-size in the examined locations was as follows: KI>SO>ZA>CA>SM>PA. "13" variety had the highest percent of 2.5 mm-seed-size in ZA, SM, PA and CA locations, while "6" variety had the highest percent of 2.5 mm-seed-size in SO location and "11" variety in KI location. "13" variety had the highest percent of smaller 2.0 mm-seed-size in PA and ZA locations and 2.2 mm-seed-size in SO, ZA, SM and PA locations. © 2010 University of Bucharest.

The aim of research was to establish the influence of seed size on grain weight per spike of three wheat varieties. A trial was set up using split-plot method in four replications in Pančevo in the period 2004-2006. The seed was divided according to the size in four fractions: 1.8, 2.0, 2.2, 2.5 and 2.8 mm. A significant interaction was determined between the tested varieties and the years of testing, whilst a highly significant interaction was determined between the years of testing and the seed size, the varieties and the seed size, between the tested varieties, the years of testing and the tested seed size. The highest grain weight per spike was determined in PKB-Christina variety (2.29 g), and Pobeda variety (2.25 g), whilst Vizija variety had the lowest grain weight per spike (2.11 g). The difference was highly significant. The analysis of variance determined a highly significant difference between the years when the experiment was conducted, which is often seen in this region. Highly significant differences in the grain weight per spike were determined at different seed sizes. Larger seeds produced higher grain weight per spikes, highest weight being obtained with largest seeds (≥ 2.8 mm).

A trial was set up in field conditions during 2003/04-2005/06 with seven different treatments of seed protection and three winter wheat varieties. Vizija variety had lower mass of 1,000 grains in comparison with Pobeda and PKB-Christina varieties, the difference being highly significant. By changing seed protection mode, the mass of 1,000 grains changed. A highly significant difference was established between control (39.8 g) and the variants treated by diviconazole (41.5 g). However, the mass of 1,000 grains of variants treated by difeconazole, carboxine + tiran and tebuconazole + triazoxine was at the level of controls and significant differences among these treatments were not determined. Treatment of electronic seed protection by means of plasma electrons showed significantly lower mass of 1,000 grains than it is the case of fungicidal protection by diviconazole, being on the level of control. Highly significant differences were established between years when the research was performed. High interactions between variety x years, variety x treatment, year x treatment and variety x year x treatment, were established. Strong positive correlation was established between mass of 1000 grains and wheat yield.

In the period from 2002 to 2005, grain yield of fifteen wheat varieties grown in Serbia was studied in seven locations. At a triennial cross section, the proportion of genotypic variance was 51.56 %, and genotypic variance x environment 26.34 %. The genotype "cip" had the highest grain yield in ZA, SO, SM, and CA environments, while the genotype "dra" had the highest grain yield in PA and KI environments. Other corner genotypes, such as "zit", "tek", "viz" and "min" did not have high grain yields in any tested environment. The average grain yield distribution in the examined environments was as follows: SO>SM>CA >ZA >PA > KG > KI.

The objective of this work was to evaluate the effects of diverse rhizosphere bacteria on growth and nutrient uptake of spring oats and spring barley plants in the greenhouse conditions. All the rhizobacterial strains tested (Sinorhizobium meliloti L3Si, Bacillus megaterium SNji, Pseudomonas sp. L2Cr and LG, Enterobacter sp. E1 and Azotobacter chroococcum AV and 7310-22V) showed some of the plant growth-promoting characteristics such as, phosphate solubilization, indole-3-acetic acid (IAA) and siderophore production. Plant response to rhizobacterial inoculation depended on the applied strain and plant species examined. Inoculation with most of the rhizobacterial strains as well as their mixture, significantly increased shoot dry weight (SDW) and shoot N, P and K content of oat plants compared to the untreated control Ø (without bacteria inoculation and mineral fertilizers). The best in promoting oat growth were S. meliloti L3Si, A. chroococcum 7310-22V strains and mixture of all strains. Only two strains, Pseudomonas sp. L2Cr and A. chroococcum AV, significantly increased SDW and shoot N and K content of barley plants. Shoot dry weight of plants following inoculation increased from 11 to 36% in oats and up to 16% in barley plants compared to the controls. © 2014 University of Bucharest.
