AB  - Considering the area and global production of the soybean, a relatively small number of papers address different aspects of its cultivation patterns and place in crop sequences. This leads to a lack of knowledge on the role and significance of soybean in different European cropping systems (CS). There is a consensus that soybean is favourable preceding crop and alongside soybean yield increases in crop rotations, however, the length and cropping patterns significantly affected the “rotation advantage” of soybean cropping systems. On the contrary, soybean monoculture has been widely used in practice despite potential adverse effects and higher risk of production. Therefore, the aim of this study was to assess yield differences of selected soybean cropping patterns in relation to the temperate climatic condition for 2008-2016 period. Analysed CS foreseen growing soybeans with maize (M), winter wheat (W) sugar beet (B) and soybean (S) as follows: (i) unfertilized 3-year rotation (MSW), (ii)3-year rotation (MSWf), (iii) 3-year rotation + cover crops (MSWccf), (iv) 4-year rotation (MSWBf), (v)monoculture SSSf and (vi) 3-year rotation with manure (MSWam). The trial was part of the long-term experiment“Plodoredi“ on the experimental station Rimski Šančevi of the Institute of Filed and Vegetable crops Novi Sadestablished on Haplic Chernozem. Regular tillage operations were used including mouldboard ploughing inautumn, compactor for levelling furrows in spring, multi-tiller for seedbed preparation and sowing in April. Inter-row cultivation and plant protection were done in May. Fertilization was not applied for soybean directly but forother crops in rotation with respect to soil chemical properties and anticipated yield. During 10 years period leadingsoybean varieties was grown with addition of biological fertilizer Nitragin. In average, a significantly higher yieldwas obtained at the 3-year fertilized rotation (3.25 t/ha) and the lowest at the monoculture (1.7 t/ha). Among theinvestigated years, a higher yield was obtained in 2013. and the lowest at 2017. A highly significant correlationwith soybean yield was found for rainfall (r=0.78** p<0.01) and a significant correlation for the temperature(r=0.74*, p<0.05) during the vegetation period (April-September). Climatic data evaluation reviled that asignificant effect on soybean yield for the temperature was found for August. For monthly sum rainfall, asignificant effect on yield was found for the June compared to other months. Our study demonstrates that soybeanin 3-year rotation benefited from crop sequence compared to monocropping. In addition, animal manure used formaize has not significantly affected soybean yield as well as growing soybean in a 4-year rotation. Maindisadvantages in monocropping are weed control and less efficient plant protection. Long-term unfertilizedsoybean demonstrated the adaptability of grown verities to low input systems and showed potential of sustainingyield in favourable years but the crop yield largely depends on the performance of winter wheat and maize.

AB  - The aim of the paper is to enlighten the role that organic agriculture can have in the achievement of Sustainable Development Goals (SDG). Currently, sustainable agriculture systems are not adequately recognized in SDG and supported by the decision-makers. Given that agriculture plays one of the key roles in sustainable development accomplishment, the expansion of an organic agriculture can be a basis to implementing SDG. Organic agriculture has multiple benefits as most valuable option in redesigning food systems to achieve ecological, economic, and social sustainability. Moreover it could encompass and establish food system from field to fork necessary to com-plete the SDG without oversize resource depletion and negative impact on the environment. The study showed that by placing organic agriculture high in the agenda of SDG it is possible to create conditions for sustainable development while identify and manage trade-offs in agriculture and maximize co-benefits.

AB  - Buckwheat and soybean are regarded as important crops in organic production and their production
could contribute to achieving farm sustainability. However, this significance derives
from a preceding effect, but less research is done on these crops as major crops. The aim of
this study is to examine soil properties under different mulches and bio-fertilizers in soybean
NS Kaća and buckwheat Novosadska. The experiment was set up in semiarid conditions in the
Center for organic production in Selenča with 3 types of mulches: wood chips, straw, living
mulch as well as commercial fertilizers and soil enhancers: organic NPK fertilizer, Ascophyllum
nodosum extract and microbiological stimulator. Mulches were helpful in maintaining
the physical properties of soil, but they could not preserve the chemical properties of soil.
Buckwheat manifested better chemical and physical soil properties compared to soybean. Our
results showed differences regarding mulch application in terms of impact on soil, which could
serve as a basis for improving the management of buckwheat and soybean under organic production
systems in semiarid conditions.

AB  - Spelt wheat (Triticum spelta L.) is regarded as a crop with high nutritional properties. Cultivar Nirvana was analyzed on nine locations in semiarid conditions of northern Serbia in order to assess the effects of different agroecological conditions on the organic spelt wheat production, grain yield and yield components, as well as the quality of the spelt wheat. The highest dehulled grain yield was obtained in Nadalj organic farm (3.98 t ha-1) on a carbonated chernozem, and the highest protein content in whole grain flour was found in organic spelt wheat from Pančevo (13.94%). Correlation analysis showed significant positive correlations among grain yield, spike length, spike weight, number of grains per spike, 1000-grain weight and harvest index and among plant height, spike length, weight spike, and grain weight per spike. Our study indicated that growing spelt wheat in northern Serbia could result in higher grain yield, but protein content depended on crop management on each location.
AB  - Zbog svojih nutritivnih osobina, krupnik (Triticum spelta L.) je sve više u interesovanju organskih proizvođača i potrošača. U cilju unapređenja organske proizvodnje i uvođenja alternativnih kultura, sprovedeno je istraživanje na ovoj vrsti pšenice kako bi se sagledao uticaj različitih agroekoloških uslova na prinos i komponente prinosa, kao i kvalitet krupnika. Predmet istraživanja bila je sorta krupnika Nirvana, a istraživanje je obavljeno na 9 različitih lokaliteta u Vojvodini i u okolini Beograda na kojima je krupnik gajen u sistemu organske proizvodnje. Najveći prinos oljuštenog zrna krupnika utvrđen je na organskoj parceli u Nadalju sa 3,98 t/ha na karbonatnom černozemu, a najveći sadržaj proteina (13,94%) u integralnom brašnu sa organske parcele iz Pančeva. Korelaciona analiza je pokazala da na ispitivanim lokalitetima postoji statistički značajna korelacija između prinosa krupnika i dužine klasa, mase klasa, broja zrna, mase 1000 zrna i žetvenog indeksa, a takođe postoji uzajamni uticaj između visine biljaka, dužine klasa, mase klasa i mase zrna po klasu. Iako je krupnik relativno skromnih zahteva prema plodnosti zemljišta i podnosi nepotpunu agrotehniku, utvrđeno je da odlično reaguje na đubrenje stajnjakom sa produženim dejstvom i na intenzivniju agrotehniku pri kojoj se mogu postići prinosi i do 4 t ha-1 oljuštenog zrna. Najveći uticaj na prinos su imali vreme setve, raspored i količina padavina, kao i obezbeđenost biljaka potrebnim hranivima. Takođe, utvrđeno je da pravilna agrotehnika može da ublaži negativni uticaj nepovoljnih uslova spoljašnje sredine, što je uticalo da se na različitim lokalitetima ostvare visoki prinosi.
