The first one (TI) is traditional way of production, where number of irrigation and water use for irrigation are based on free farmer choice. The second variant (FI) represents full irrigation, where maize was irrigated up to full field water capacity in depth of 1m. The third variant (DI50) is irrigation up to 50% from FI. They confirmed that for TI variant, average 10 868 m 3 /ha water is used by farmers, what means about 14 % more water use, compared with variant FI and 128 % more water use, compared with DI 50. Because of the fact that water saving is significant and water use is controlled, a high yield and better value of production was realized. According that, the farmers who will practice variants with controlled irrigation water usage, would have higher profit (average 13.5 indexes) of invested capital.

Debates over the genetically modified (GM) crops are taking place continuously and all of the countries do not have equal approach to these crops. The most of the world countries do not cultivate GM crops, and some of them have bans on cultivation. However, since 1996 the areas under GM crops and the number of countries with cultivation are increasing. The purpose of this work is to analyze the GM crops cultivation in the period 1996-2013. The review of cultivation is presented by countries, crops and modified traits. The result of the analysis demonstrate that the total area in 2013 have increased 100-fold, compared to 1996. The number of countries growing GM crops was increasing until 2011, reducing for one county afterwards. Within the European Union, beside the strongest attitude against cultivation of GM crops, five countries continue to plant such crops. Soybean, corn, cotton and c...

In this research, have been evaluated the yield and quality of five maize hybrids PKB323, NSSC333, ZPSC704, NS721, NS770, growing in Shtip area.Received results for grain yield, corresponds to other investigations, where hybrids with longer vegetative period (bigger FAO group of maturity), have higher yield. Smallest average grain yield shows the hybrid NSSC 333 (4.05 t/ha), while the largest shows NS 721 (14.05 t/ha). In 2009, average yield of all hybrids was 9.3 t/ha, while in 2010, the total average yield was 9.2 t/ha. Regarding quality properties of the grain, in 2009, PKB 323 shows biggest percentage of total sugars (72.1%), compared with other hybrids. In 2010, it was ZPSC 704 (72.5%). In both years, the biggest protein content was determined in NS 721 (8.9%). The biggest oil content was received in NSSC 333 (3.4%) and PKB 32...

The yield is the basis for determination of the proper hybrid in relation to the length of the vegetation, and strongly depends on the elements that determine it. In this research, have been evaluated the elements of the yield and the factors that affects them at the maize hybrids PKB323, NSSC333, ZPSC704, NS721, NS770. All hybrids shown one cob per plant, but the length of the cob varied and depends on the year, location and genotype. The shortest average length of the cob was determined at the hybrid NSSC333 (18.75 сm), while the largest at NS721 (23.75 cm). The hybrids from FAO300 maturity group have shown lower average value for cob diameter compared with hybrids from the FAO700 group. In this study, the hybrids with the smallest average length of kernel, were NSSC333 and NS721 (0.87 cm), and the hybrid with the highest average length was ZPSC704 (1....

The large agricultural area covered by maize, coming as result of introduction of new hybrids with different vegetation period, therefore, the possibilities for its production are growing. But, because of the production of new hybrids, it is necessary for their investigation in new agricultural conditions. In this research was investigated adaptability of the maize hybrids PKB323, NSSC333, ZPSC704, NS721, NS770, in conditions of Shtip region. Through the research of morphological properties, has been confirmed the reaction of each hybrid in certain agro ecological conditions. The examined genotypes showed different height, which increases regarding vegetation period. Average height for earlier hybrids was 1.98m in 2009, and 1.92m in 2010. Later maturity hybrids have higher stem height, with 2.40m in 2009, and 2.43m in 2010. The cob height followed the stem height, but number of the cobs per plant was equall...

Polymorphysm and allelic variations in the Glu-A1 loci was determined through characterization of Ax-null, Ax1 and Ax2* alleles, and in Glu-D1 loci through characterization of Dx2+Dy12 and Dx5+Dy10 alleles. Ax null, that has negative influence on bread-making quality, was detected in 77.66% of the genotypes. The allelic pair Dx5+Dy10 was present in 68.09% of the genotypes. Only 8.51% of the analysed genotypes had the allele Ax1. According to the identified alleles in the Glu A1 and Glu D1 loci, the genotypes were grouped in two main clusters, 64 in the first and 30 genotypes in the second cluster. Both clusters consisted of three subclusters, comprising different number of genotypes. The most of the genotypes belonged to the subgroups 1a (presence of Dx5+Dy10) and 2a (presence of Dx2+Dy12). Genotypes in the 2a subgroup had Ах-null in Glu-A1 locus and Dx2+Dy12 in Glu-D1 locus, negatively influencing the wheat bread-making quality. These genotypes are not recommended to be used in a breeding program for improving wheat bread-making quality. Genotypes from the subgroups 1b and 1c possessed the alleles Аx2* and Ax1 in Glu-A1 locus and Dx5+Dy10 in Glu-D1 locus, indicating good breadmaking quality. The superior breeding lines with improved quality, good agronomic characteristics and high yield have to be evaluated for their adaptability and stability. The lines with a complex of positive characteristics may be submitted for registration of new varieties. Further investigations of the material are needed for the other loci influencing the wheat bread-making quality.

The experimental field consisted of three treatments with irrigation (soil matrix potential of 20, 30 and 40 kPa), as well as unirrigated, control. Irrigation schedule was determined by tensiometers on the basis of the observed soil matrix potential values. The highest potato tuber yield (48.30 t ha-1) was observed at the variant where soil matrix potential of 30 kPa was kept. Potato tuber yield was the highest when water consumption for evapotranspiration amounted from 491.3 to 498.6 mm, while at higher or lower values of water consumption for ET tuber yield dropped. Water use efficiency of potato during the studied period ranged from 81.23 to 98.21 kg ha-1 mm-1. The data concerning tuber yield, evapotranspiration and WUE of potato point to the fact that, in order to reach high potato tuber yield and quality, one ought to keep soil matrix potential at levels around 30 kPa for the conditions of south Serbia.

A total of 2217 maize (Zea mays L.) landraces, collected in the former Yugoslavia, are stored at Maize Research Institute (MRIZP) gene bank. During 2014, new collecting missions were organized in the eastern and western parts of Macedonia. According to collecting site and kernel type, 14 samples from the Faculty of Agricultural Sciences and Food, R. Macedonia were chosen for the comparison and identification of possible duplicates, through coupling with the 16 MRIZP gene bank accessions from the same area and kernel characteristics. Phenotypic characterization was done for 21 traits according to International Board for Plant Genetic Resources descriptors for maize. The Principal Component Analysis (PCA) identifies five PCs with Eigenvalue > 1, explaining 80% of the total phenotypic variation. The most discriminative traits with the strongest positive associations were tasseling and silking dates, plant height, leaf length and ear length. Compared to the exsitu populations, the number of alleles and the number of specific alleles, showed a significant decrease in the in situ populations. Twelve unique alleles were detected in samples from MRIZP gene bank, and only four were found in new Macedonian samples. Cluster analysis of morphological and molecular markers distinguished groups of maize accessions with distinctive morphological traits and genetic profiles that will be useful for conservation, and management of gene bank collection, as well as for possible utilization in breeding.

In Republic of Macedonia, barley is sown on a quarter of the entire cereal production area. On the National variety list, there is only one registered variety of spring barley-Makedo. Barley grain yield can vary from year to year. It is highly dependent on of the climate conditions, as well as the agronomic measures applied during the vegetation period. One of the most important measures is the fertilization of the crops. Starting from the fact that the use of chelate fertilizer solutions, using the spray-on foliar method is in the early development phase, an experiment was conducted using spring barley Makedo variety, and three types of chelate fertilizer solutions (Agrosal N12P5K7+МЕ, Agrosal NH4NO3 50% and Agrosal N31P0K0+ME), applied in 6 different concentrations (0.5, 1, 3, 5, 10 and 15 percent). The average grain yield was 1 347 kgha-1, the best results of this trait were registered at the crops treated with Agrosal N12P5K7+МЕ in a 1 percent solution, while the lowest yield was measured on the crops treated with Agrosal N31P0K0+ME in the concentration of 0.5 percent. The quality highly varied depending of the different applied treatments. Highest protein content was registered on the crops treated with Agrosal N31P0K0+ME in a 10 percent solution, whilst the lowest on the crops treated with Agrosal N12P5K7+МЕ, in a 0.5 percent solution.

Starting from the fact that the use of chelate fertilizer solutions, using the spray-on foliar method is in the early development phase, an experiment was conducted using spring barley Makedo variety, and three types of chelate fertilizer solutions (Agrosal N12P5K7+МЕ, Agrosal NH4NO3 50% and Agrosal N31P0K0+ME), applied in 6 different concentrations (0.5, 1, 3, 5, 10 and 15 percent). The average grain yield was 1 347 kgha-1, the best results of this trait were registered at the crops treated with Agrosal N12P5K7+МЕ in a 1 percent solution, while the lowest yield was measured on the crops treated with Agrosal N31P0K0+ME in the concentration of 0.5 percent. The quality highly varied depending of the different applied treatments. Highest protein content was registered on the crops treated with Agrosal N31P0K0+ME in a 10 percent solution, whilst the lowest on the crops treated with Agrosal N12P5K7+МЕ, in a 0.5 percent solution.

Analysised 4 varietetes soybean in four differentseedling dues, during a period of three years. In average (1998-2000), by allsorts, the plaving were is from 8,3 cm. where the first to 10,2 cm. where thefourth seedling due. With increase on the thicknees the crop in the later seedlingdues, it is increasing and the height on placing on the first pod. The sort withlonger vegetation (balkan), where is heightest, and (015) with shortestvegetation with lowest placing first pod. While the most available productiveyear (1999), the first pod where is heightest placing, and lowest in theunavailable (dry), 2000 year
