AB  - A two-year field trial was conducted to study the effects of biohumus, biofertiliser, and soil conditioner application on spelt grain yield in different regions (plain, hilly, and mountainous regions) in Serbia. An analysis of economic efficiency indicators of spelt production in organic farming systems was also performed. The field experiment had a randomised complete block design with three replicates in each of the three regions. One winter spelt cultivar was also studied. The largest differences in spelt yield compared to control were found in the plain region in the biohumus + biofertiliser treatment (28.0%) and the hilly region in the organic fertiliser + zeolite treatment (28.8%). The differences in grain yield between control and treatment conditions in the mountain region were insignificant. Analysis of the economic effects of organic spelt production found a significantly lower gross margin in treatments with expensive organic fertilisers (3955.05 and 1104.75 € ha–1) than the control (5094.31 and 1833.85 € ha–1), leading to the conclusion that their application was not economically justified despite the increases in grain yield. The highest production costs (3569.71 € ha–1) were observed in treatments in the hilly region, resulting in the lowest benefit-cost ratio (0.1), while the greatest benefit-cost ratio was recorded in treatments in the mountainous region (2.1). Following the economic analysis results, a significant negative correlation between the benefit-cost ratio and the total production costs (r= –0.91**) was determined and a positive correlation between the gross margin and grain yield (r=0.66*). These results lead to the conclusion that the management strategy of spelt production in organic farming systems should be harmonised with the soil and agro-ecological characteristics of the region and directed at decreasing the costs and share of external inputs. In this case, organic spelt production can be economically profitable.

Highlights
- Organic fertilisers and soil conditioners affect spelt grain yield.
- The analysis of the economic effects of organic spelt production concluded that fertiliser application was not economically justified despite the increases in grain yield.
- Treatments in the plain region displayed the best production results compared to mountain region treatments, but these did not have the best benefit-cost ratio.
- Knowledge of production costs is an important element in improving the economic efficiency of organic farming systems.

AB  - Bursaphelenchus mucronatus kolymensis (Korentchenko) Braasch et al. (1), also referred to as the European type of B. mucronatus, is morphologically very similar to the pine wood nematode (PWN) B. xylophilus (Steiner & Buhrer) Nickle, the causal agent of pine wilt disease. The main morphological difference between the two species is the shape of the female tail mucro (3); however, some populations of PWN vary in mucro shape, which can lead to misidentification. Since PWN was found and identified for the first time in Portugal in 1999 (4), concern about the spread of PWN to pines and other conifers all over Europe has increased. Therefore, the PWN survey in every European country is essential. In 2011, the Serbian Ministry of Agriculture, Forestry and Water Management implemented phytosanitary measures for detection of PWN in the territory of the Republic of Serbia. In September 2013, wood samples were collected from a 40-year-old wilted Pinus sylvestris located on Divcibare Mountain, western Serbia. Nematodes were extracted by a modified Baermann funnel method. Nematode specimens (10 females and 10 males) were characterized by an Aphelenchoid-type esophagus, female vulva flap, mucro on the end of female tail, and males with paired arcuate spicules. Morphological identification matched that of B. mucronatus kolymensis (1). The specific morphometric evidence for this European type subspecies of B. mucronatus was sub-cylindrical female tail with mucro 3 to 4 μm long, digitate, well offset from tail (5). Species identification was confirmed by PCR-RFLP of the rDNA ITS region using one female and one male nematode separately (2). The sizes of restricted DNA fragments as determined with agarose gel and capillary electrophoresis were in compliance with reported data in the literature (2,4) and support the identification of the nematode as B. mucronatus kolymensis. To our knowledge, this is the first report of any species belonging to Bursaphelenchus genus in Serbia. The presence of B. mucronatus kolymensis in Serbia indicates the possibility of establishment and spread of PWN. Therefore, the measures taken in case of PWN occurrence should be prepared and training foresters to identify pine wilt disease symptoms should be encouraged in Serbia.
