During the period 2010-2011 about 2.113 million ha of buckwheat was sown annually worldwide. Average yield of buckwheat during the monitored period was 913 kg ha-1. Areas and average yield have a rising tendency. The most significant producers of buckwheat in the world are: China, Russia and Ukraine. In Serbia buckwheat is produced on small areas. The paper presents results of testing of four buckwheat varieties, produced on plots of the Institute for crops and vegetables as follows: Novosadska, Godijevo, Bamby and Češka. Analysis of average yield has shown that Novosadska variety produced statistically significant higher yield (2626 kg ha-1) compared to the other varieties tested (p <0.05). From the results shown we can see that buckwheat yield in Serbia is significantly higher compared with the world average yield, which tells us that this plant can be successfully produced in our agro-ecological conditions of growing.

SUMMARYSpelt [Triticum spelta (L.)] is a wheat species that is becoming increasingly popular in the production of safe food, and also due to rising possibilities for ecological farming of this alternative crop. Two-year research on possibilities of growing spelt was carried out during 2011 and 2012, on the experimental field of the Institute of Agriculture in Banja Luka (Republic of Srpska). The subject-matter of the research was two spelt cultivars: Hungarian cultivar Ekö-10 and Serbian Novi Sad cultivar Nirvana. The trials were set up in the form of a randomised block design with three repetitions. The trials investigated the following morphological and productive traits: plant height, spike length and 1000-grain weight. The results show that the cultivars have a large genetic potential. Statistically, Nirvana had significantly higher plants (150.66 cm), longer spikes (8.37 cm) and higher1000-grain weight (46.39 g) than cultivar Ekö-10 that had lower values in the both years of research. Identifying correlations enabled better understanding of interrelations among the traits and their balancing, in order to increase yield per unit area. The conditions of the trial site were proved favourable for growing spelt.

Khorasan wheat occupies a special place in the group of new-old cereals (Triticum turgidum, ssp. Turanicum McKey). It is an ancient species, native to eastern Persia, that is very close to durum wheat by morphological characteristics. Investigations were carried out in agro ecological conditions of the eastern Srem, with two wheat populations with dark and bright awns as objects of study. The following morphological and productive characteristics were investigated: plant height (PH), spike length (SH), number of spikelets per spike (NSS), absolute weight (AW) and grain weight per spike (GW), seed germination (G) and grains yield (YG). Field micro-experiments were set on the carbonate chernozem soil type on loess plateau in 2011 and 2012. Hand wheat sowing was conducted in early March with drill row spacing of 12 cm. The experiment was established as complete randomized block system with four replications. Tending crops measures were not applied during the growing season. Plants were grown without usage of NPK mineral nutrients. Chemical crop protection measures were not applied, although powdery mildew (Erysiphe graminis) was appeared before plants spike formation in a small extent. The results showed that both populations have a genetic yield potential. In general, both populations manifested a satisfactory tolerance on lodging and there was no seed dispersal. Plants from bright awns population were higher, had longer spikes and larger number of spikelet?s per spike. However, plants from dark awns population had higher absolute weight and grains weight per spike, as well as grain yield per plant. Strong correlation connections were identified among the investigated characteristics. The determination of correlations, as well as direct and indirect affects, enabled easier understanding of the mutual relationships and their balancing in order to improve the yield per unit area.

Wheat is, in quantity, the third largest crop produced in the world and therefore contributes greatly to the world economy both globally and in Serbia and Bosnia and Herzegovina-B & H. With wheat, worldwide it is sowing about 2.20 million ha annually and in Republic of Serbia wheat cultivated in 588.820 ha. The present trial was carried out to study the growth rates of yield, production and market of wheat in B & H. During the period 2010-2016, wheat was sown of Bosnia and Herzegovina on 63606.30 ha. There is trend in increasing of areas under wheat with a rate of 0.99% per year and, it varies. Average yield of wheat during the monitored period was 3.58 t ha-1. Average export of wheat in the tested period was 41750 t and had a tendency to increase with a rate of 25.67% and variation (CV = 104.41%) while average import of wheat was 398750 t and had a tendency to increase with a rate of 0.82% and variation (CV = 10.37%). The highest import was achieved in 2016 (398750 t) and the lowest in 2013. External trade of agro-industrial products and trade liberalization implies the necessity of raising the technological level of production, productivity, efficiency and application of marketing management.

The aim of the work is the analysis of current business situation in which the apple producers in Bosnia and Herzegovina are positioned with development and use of holistic marketing concept as a model for improving the competitiveness of apple producers in Bosnia and Herzegovina. The methodology, which is applied in this work, is a combined qualitative and quantitative research technique. The in-depth interview is used for qualitative research, and for quantitative research the analysis of the import, export, production, trade and the cash flow data, available from statistical agencies, were used. The results showed that the new, developing, apple production strategy is necessary in order to correspond to the business challenges of the 21 st century. In the new model of developing, it is suggested that the holistic approach to marketing has the central role. Holistic marketing, with its elements, has a potential to improve competitiveness on the domestic market and to create conditions for stable development of the apple production in Bosnia and Herzegovina.
