The field pea is very important when it comes to the nutrition of domestic animals, due to a high content of proteins in its grains and aboveground biomass. The aim of this study was to examine genetic variability in quantitative traits of newly created field pea hybrids. The researchers studied two cultivars, one line and their F<sub>3</sub> and F<sub>4</sub> hybrids. The following quantitative traits were analysed: number of pods per plant, number of grains per pod, 1000 seed weight and grain yield. The largest number of pods per plant was recorded for the Baccara × L-CC line hybrid, with a statistically significantly larger (P < 0.01) number of pods per plant than all the other investigated genotypes, lines and hybrids. L-CC line × Baccara, and Saša × L-CC line had a significantly larger (P < 0.05) number of grains per pod. The smallest number of grains per pod was recorded for the Saša and Baccara × Saša hybrid. The genotype vs. year interaction had a significant (P < 0.05) influence on 1000 seed weight. Significantly higher (P < 0.05) 1000 seed weight was recorded for the Baccara genotype, when compared with all other investigated genotypes, lines and hybrids. The lowest 1000 seed weight was recorded for the L-CC line. The genotype × year interaction had a significant influence on the seed yield of field pea. During this research, high seed yields were achieved by the Baccara genotype and Baccara × L-CC line and Baccara × Saša hybrids.
The object of this study was a two-year trial (2009 and 2010) regarding variability of morphological characteristics of species belonging to Sorghum genus, more specifically interspecies hybrid between sorghum and Sudan grass Siloking as affected by different applications of nitrogen. The following morphological characteristics were analysed: plant height, number of leaves, leaf ratio, stem ratio, and number of shoots. Samples were taken from the first cut when the effect of the applied nitrogen doses was the strongest. The results showed that increasing nitrogen quantities significantly affected the tested morphological characteristics, especially the intensity of tillering (increased number of secondary stems), number of the formed leaves, and ratio of leaf weight in the total above-ground biomass. The effect of applied nitrogen depended on the weather conditions, i.e. distribution of precipitation, so that plants reached maximum height when 105 kg N ha-1 was applied in the dry year and 180 kg N ha-1 in the wet year.

Sažetak: Cilj je da se uz istorijsku analizu i prikaz modela društveno odgovornog poslovanja (DOP-a) koji prevladava u EU, empirijskim istraživanjem na ograničenom uzorku preduzeća u BiH iz oblasti turizma i uslužnih djelatnosti ustanovi koliko upravljačke strukture preduzeća, u srazmjerno mladoj i slabo razvijenoj privredi, poznaju pojam, svrhu i politiku društvene odgovornosti preduzeća. Da li prema navednoj postavci postoji uključenost zaposlenih u formulisanju i primjeni modela DOP-a. Svjesni činjenice da je koncept korporativnog upravljanja sve prisutniji u modernoj ekonomiji treba postaviti pitanje: koja je razumna cijena tehnološke ekspanzije i do koje granice je moguć ukupan rast? Do kojih granica se može kretati tolerancija uslova rada? Predmet istraživanja je društvena odgovornost preduzeća u BiH iz oblasti turizma i uslužnog sektora. Istraživanje je usmjereno na shvatanje važnosti provođenja koncepta DOP-a i promocije dobre prakse te na stepen poštivanja mandatorne, odnosno fakultativne odgovornosti preduzeća i njihovu spremnost da zanemare iste ukoliko određene okolnosti takav potez nametnu kao kratkoročno rješenje. Područje istraživanja je poznavanje i primjena modela društveno odgovornog poslovanja određenog broja BiH preduzeća iz oblasti turizma i uslužnih djelatnosti, ali i menadžmenta koji tim preduzećima upravlja.Ključe riječi: Društveno odgovorno poslovanje, mandatorna odgovornost, fakultativna odgovornost, društvena zajednica UVODSigurno je da savremeno društvo donosi veliki progres, da moć nauke, kulture, umjetnosti, tehnike, tehnologije, određenih interesnih grupa, doprinosi uspješnom razvoju društva te da za posljedicu imamo unapređenje kvaliteta života savremenog čovjeka. Ipak, primjetno je da upravljačke strukture, monopolske pozicije pojedinih elita određuju sudbinu i kvalitet življenja mnogima. Može se reći da takvim djelovanjem 1 Autor je doktorirao na polju odživog razvoja. 2 Doktorant u Beogradu iz oblasti turizma i zaštite okoline
Technological quality of wheat is defined by physical and chemical indicators of quality and its baking properties. To make wheat a commodity, there are certain requirements to be met, defined by minimum values of trade quality indicators. As hexaploid wheat, spelt (Triticum spelta L.) belongs to a group of alternative cereal grains high in gluten, and its flour is therefore used for making most pastries. Due to its high nutritional value, spelt flour is used to enhance the quality or flavour of wheat bread and other bakery products. Two-year research was conducted during 2011 and 2012 to investigate protein content in crops grown on the Eutric Cambisol soil type. The research was conducted on two spelt cultivars: Hungarian Ek? 10 and Serbian NS Nirvana. The results showed that NS Nirvana averaged a statistically significantly higher proteins content (16.76%) than Hungarian cultivar Ek? 10 (15.65%). Climatic factors, temperatures, the intensity of light and duration of seed filling had an impact on the investigated parameter. [Projekat Ministarstva nauke Republike Srbije, br. TR 31078 i br.
