Primena sensor web koncepta u poljoprivredi
Get PDFMonitoring of environmental parameters is one of the important prerequisite for the
improvement of agricultural production. Today it is possible to use a sensor network for
the detection and identification of a large number of parameters and phenomena, from
simple to complex one. The integration of data from different sensor platforms is enabled
using the Sensor Web concept which provides a way to access and setting tasks for
sensors over the Internet. The aim was to introduce the structure of the Sensor Web and to
point the possibility of their use in agriculture by providing users with accurate
information that have a significant contribution in the process of making right decisions.Kontinuirano praćenje parametara životne sredine predstavlja jedan od
značajnih preduslova za unapređenje poljoprivredne proizvodnje. Danas je moguće
koristiti senzorske mreže za detekciju i identifikaciju velikog broja parametara i pojava.
Integracija podataka sa različitih senzorskih platformi omogućena je primenom Sensor
Web koncepta koji daje mogućnost pristupu i upravljanju senzorima preko Interneta. Cilj
rada bio je upoznavanje sa strukturom Sensor Web-a i ukazivanje na mogućnosti njihove
primene u oblasti poljoprivrede pružajući korisnicima precizne podatke na osnovu kojih
će oni pravovremeno donositi adekvatne odluke
Uticaj setvene norme na prinos i kvalitet sena lucerke
Get PDFThe objective of this research was to determine dry matter yield (t ha-1) and leaf
portion (g kg-1) as affected by different seeding rates. Four alfalfa varieties, two cutting
regimes (I – early, cuts at the 10% bloom stage; II – medium, cuts at the 50% bloom
stage), and two seeding rates were compared. Higher seeding rate did not produce
higher dry matter yield. Cutting in different phenological stages of alfalfa plants had no
significant effect on the yield. Leaf portion significantly correlated with the cutting
regime, while seeding rate did not show statistical correlation.Tokom 2010-2011. godine ispitivan je uticaj različitih količina semena za
setvu na prinos sena (t ha-1) i udeo lista (g kg-1) u prinosu lucerke. U ogled su uključeni
sledeći faktori: dve setvene norme (8 i 16 kg ha-1); dva sistema kosidbe (I-rani, košenje
u fazi 10% cvetalih biljaka; i II-srednje rani, košenje u fazi 50% cvetanja); 4 sorte
lucerke (Banat VS, Nijagara, NS Alfa i NS Mediana ZMS V). Prinos suve materije se
nije značajno povećao povećanjem setvene norme. Setvom 16 kg ha-1 dobijen je isti
prinos kao i setvom 8 kg ha-1. Kosidba u različitim fazama razvića biljaka lucerke nije
značajno uticala na formiranje prinosa. Udeo lista u prinosu značajno je zavisio od
sistema kosidbe, dok veća količina semena za setvu nije uticala na povećanje kvaliteta
sena lucerke
Mesto i značaj organske proizvodnje u razvoju poljoprivrede Republike Srbije
Get PDFAgriculture in the Republic of Serbia is a strategic economic sector with a high
contribution to GDP and total employment of the population. It is characterized by the
extensiveness, variety, a large number of farms primarily family, fragmentation of
holdings, low average economic size of the farm. On the other hand these are the
advantages and prerequisites for the development of a successful organic farming in this
region. Although organic production in the world has a positive trend, it is stagnant in
Serbia and there is little participation in the overall development of Serbian agriculture.
The increase in the area of crop production should contribute to increasing organic
livestock production, which is expected to value added products. Development of other
organic agricultural system should provide sufficient health safety and high value
products for domestic needs and export to the world market. In this sense, each of the
relevant factors has to make its maximum contribution in achieving objectives.Poljoprivreda u Republici Srbiji predstavlja stratešku privrednu granu sa
visokim doprinosom BDP-u i ukupnoj zaposlenosti stanovništva. Karakteriše je
ekstenzivnost, raznovrsnost, veliki broj poljoprivrednih gazdinstava prvenstveno
porodičnih, usitnjenost poseda, niska prosečna ekonomska veličina gazdinstva. S druge
strane, ovo su prednosti i preduslov za uspešni razoj ekološke poljoprivrede na ovim
prostorima. Iako organska proizvodnja u svetu ima pozitivan trend u Srbiji ona stagnira i
ima malo učešće u ukupnom razvoju srpske poljoprivrede. Povećanje u domenu ratarske
proizvodnje trebalo bi da doprinese porastu organskog stočarstva, od koga se očekuje
dodata vrednost ovih proizvoda. Razvoj ostalih organskih poljoprivrednih sistema bi
trebao da obezbedi dovoljno zdravstveno bezbednih i visokovrednih proizvoda za
domaće potrebe i izvoz na svetsko tržište. U tom smislu svaki od relevantnih činilaca
treba da da svoj maksimalni doprinos u realizaciji postavljenih ciljeva
Određivanje sadržaja heljde u hlebu analizom metil estara dominantnih masnih kiselina
Get PDFFive samples of bread were prepared by mixing wheat and buckwheat flour. The
content of buckwheat flour is raised from 0, 20, 40, 50 to 60%. Fatty acids were
extracted from bread crusts and crumbs using n-hexane, and derivatised with TMSH
(trimethylsulfonium hydroxide in methanol). Fatty acid methyl esters were then
subjected to GC-MS analysis. The surface areas of the most abundant fatty acid methyl
esters were integrated, and further subjected to the multivariate data analysis. The
results show a clear relationship between the content of dominant fatty acid methyl
esters and content of buckwheat flour in bread.Pet uzoraka hleba je pripremljeno mešanjem pšeničnog i heljdinog brašana.
Udeo heljdinog brašna je povećavan od 0, 20, 40, 50 do 60%. Ekstrakcijom sa heksanom

Managing Change through Management Development Process
Get PDFManagement development is not an easily defined single concept, it is
concerned with developing the experience, attitudes and skills necessary to become or
remained an effective manager. Every organization in meat industry has physical,
financial and human resource needs, but fundamental need of any organization is the need
for an effective management team. After the management development needs of the
organization have been determined, objectives for the overall management development
program and for individual program must be established to meet those needs. After the
company’s needs have been assessed and its objectives stated, management development
programs can be implemented. The initial phase of an organizational development effort is
a recognition by management that organizational performance can and should be
improved. Following this initial recognition, most organizational development efforts
include the following phases – diagnosis, strategy planning, education, and evaluation
Distribucija i sezonska dinamika Ephemeroptera i Plecoptera u rijeci Oskovi
Get PDFInvertebrates are the basisof biodiversity of Bosnia and Hercegovina's fauna, but
just invertebrates are the least researched. During the research of EPHEMEROPTERA
and PLECOPTERA in the river Oskova there were sampled 23 species of
EPHEMEROPTERA with a total of 398 individuals and 17 species of PLECOPTERA
with 352 individuals. Based on the research conducted in the river Oskova we obtained
data about the composition of macroinvertebrate communities, determined taxa and
distributions and obtained data on water quality. The results indicate favorable
conditions for life of macroinvertebrates, relatively high diversity, and can be used for
finding effective control and biomonitoring of the analyzed ecosystem.Beskičmenjaci čine okosnicu biodiverziteta bosansko-hercegovačke faune, ali
su upravo beskičmenjaci i najslabije istraženi organizmi. Prilikom istraživanja
EPHEMEROPTERA i PLECOPTERA u rijeci Oskova uzorkovane su 23 vrste
EPHEMEROPTERA sa ukupno 398 jedinki i 17 vrsta PLECOPTERA sa 352 jedinke. Na
osnovu sprovedenih istraživanja dobijeni su podaci o sastavu zajednica makroinvertebrata,
izvršena je determinacija taksona i njihova distribucija, što je omogućilo davanje ocjene o
kvalitetu vode. Rezultati istraživanja ukazuju na povoljne uvjete za život
makroinvertebrata i njihov relativno visok diverzitet, tako da se ovi organizmi mogu
upotrijebiti za pronalazak efikasne kontrole i biomonitoringa rijeke Oskove
Kukuruzni plamenac, Ostrinia Nubilalis hbn. (Lepidoptera, Crambidae) kao štetočina
Get PDFEuropean Corn Borer is a corn pest worldwide, present with different number of
generation and races. The economic level of looses vary from 0-100 %. Apperance,
harmffulness and voltinism are consequences of vegatation, agrometerological
conditions, cultivars and technology. In Europe and north America are detected Z, E and
H strain of pest. As a rule all strains are present in corn field. Exception is France,
where is Z strain present in corn, and E strain in hop and mugwort. The presence of
different pheromone isomer is the base of strain differentiation.Kukuruzov plamenac je štetočina kukuruza prisutna sa različitim brojem
generacija i tipova. Nivo ekonomskih gubitaka u godišnjoj proizvodnji varira od 0-100 %.
Pojava, štetnost i voltinizam posledica su uticaja vegetacije, agrometeoroloških uslova,
sortimenta i tehnologije gajenja. Na evropskom i severoameričkom prostoru utvrđeno je
prisustvo Z, E i H tipa štetočine. Uglavnom su ovi tipovi prisutni u usevu kukuruza.
Izuzetak je Francuska gde je Z tip identifikovan u kukuruzu, a E tip na hmelju i crnom
pelinu. Razdvojenost na tipove uslovljena je prisustvom feromona i njihovom
funkcionalnom praktičnom upotrebom u privlačenju mužjaka
