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). Source

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. Source

This work represents a research of non-sugar matter (the content of α- amino nitrogen, potassiumm andsodium) in the root, and their effect on the recoverable sucrose quantity of three genotypes (Esprit, Belinda and Chiara) of sugar beet from vegetation areas of different sizes. They were grown by standard agrotechnical measures for sugar beet in the densities of 80.000, 100.000 and 120.000 plants per hectare. In 2005, the highest sugar utilization coefficient (12.94%) was achieved in the variant where plant density was 120.000 per hectare (0.083 m2) and the genotype was Esprit (N-type), which was 5.48% more than that in the variant with the lowest utilization coefficient (12.23%), where density was 100.000 per hectare (0.1 m 2) and the genotype was Chiara (E-type). In 2006, the highest sugar utilization coefficient of 14.03% was achieved in the variant where plant density was 120.000 per hectare (0.083%) and the genotype Belinda (Z-type), which was 6.84% more than that in the variant with the lowest utilization coefficient (13.07%), with the density of 100.000 per hectare (0.1m 2) and genotype Esprit (Ntype). In 2007, the highest sugar utilization coefficient of 14.27% was recorded in the variant with the plant density of 80.000 per hectare (0.125 m 2) and the genotype Belinda (Z-type), which was higher by 8.26% as compared to the variant with the lowest utilization coefficient (13.09%), where density was 100.000 per hectare (0.1m 2) and the genotype was Chiara (E-type). © 2011 Academic Journals.
