Abstract: The quantitative dynamics of soil microorganisms in the rhizosphere of tobacco and tomato plants infected by broomrape /Phelipanche ramosa L./ were investigated. Parallel pot experiments with the two hosts of the parasite - Oriental type of tobacco and tomato were presented. The variants were: by introducing contamination into the soil - seeds by broomrape and control pots - without the seeds by broomrape. Experiments were carried out under controlled conditions. Soil samples for microbiological analyzes were taken from the rhizosphere, in dynamics. The microbiological analyses were executed according to Koh’s, in three replications (MPN/g a.d.s), with confidence level 0.05. The surveyed set of soil microorganisms has been comprised two indicators groups characterizing the overall biological state of the microbial communities: Autochthonous (on soil extract agar) and Oligotrophic (on diluted soil extract agar). Diversity indexes Shannon (H) and Simpson (D) and the distribution evenness (EH) in the microbial communities were determined. A statistical analysis has been made. The obtained results showed that the quantities of the two groups of microorganisms begun to change visibly around and after 20th day, compared to the amount at the rhizosphere of uninfected by broomrape plants. There was an increase at the population density of autochthonous microorganisms between 20 and 60 days and reduced significantly after this period. The trend was reversed at oligotrophic microorganisms, but the quantities were higher throughout the study period. These dynamics coincide with the phases of broomrape development - germination, formation of a haustorium (about 10-20th day) and attachment to the root of the host (up to about 40-60 days) and the above-ground phases (80-100 days). The analysis showed that microbial communities formed in rhizospheres in the presence of a broomrape had been an oligotrophic character. The relative share of oligotrophic microorganisms in these microbial communities was over 50% at both host rhizospheres.

Abstract: The number of days to flowering and growth stages, plant and stem height, panicle length, number of panicles/ m2 , 1000 grains weight of paddy and biomass yield at harvest (straw + paddy rice) were examined in the newly introduced Turkish rice varieties Efe, Hamzadere, Çakmak and Tunca. The new varieties were grown under typical rice producing conditions in the Kocani rice producing region of North Macedonia during 2013 and 2014, in field trials set up in randomized complete block design, compared to standard variety San Andrea. The results were analyzed by ANOVA and LSD test. The studied varieties in both seasons showed shorter average period from seeding to flowering (89 to 93 days across varieties) compared to San Andrea (99.5 days), as well as faster development thru the rice growth phases. The Turkish varieties had a significantly shorter plant (90.75 cm to 94.54 cm) and stem (77.00 cm to 86.53 cm) compared to San Andrea (114.50 cm and 99.63 cm). The number of panicles per m2 varied between the two years, with average values from 526.17 in Efe to 647.17 in Tunca. The 1000 grains weight of paddy ranged from 29.03 g in Çakmak to 33.47 in Hamzadere. San Andrea had significantly higher 1000 grains weight, with average value of 37.88 g. The biomass (straw+ paddy) in all varieties was higher in the first year compared to the second. The average values ranged from 28608.34 kg/ha in Efe to 33850.00 kg/ha in Çakmak. The studied Turkish rice cultivars generally showed better results for the examined characteristics than the standard San Andrea (shorter vegetative stage, faster development and maturation, lower plant height, more stable biological yield) and as such are potentially suitable for cultivation in the rice producing conditions of North Macedonia.

Abstract: At the Experimental Base of the Institute of Viticulture and Enology, Pleven, Bulgaria it was carried out a three-year planting (2014, 2015 and 2016) of a vineyard for chemicals testing for weed control. Each variant included 20 Cabernet Sauvignon vines grafted to Berlandieri X Riparia Selection Oppenheim 4 (SO 4) rootstock as it was repeated every year of the study. A single spray with Wing P (pendimethalin 250 g/l + dimethenamid P 212.5 g/l) at doses of 0.4 and 0.6 l/da was performed immediately after planting the vines and once with Stratos Ultra (100 g/l cycloxydim) at a dose of 0.2 l/da during the active vegetation stage of the wheat weeds. It was not found a negative impact on the bud germination and the shoot growth and maturation. Applied at a dose of 0.6 l/da, Wing P showed the best control over one-year weed vegetation in the vineyard as the treated vines had more intensive development and mature growth of greater length and mass.
