dc.description.abstract | A simple performance-based index was used to test performance among maize cropping systems referring to the food and raw material production, nutrient cycling and greenhouse gases regulation. Those indices are tools for aggregating and simplifying agroecosystem impact on the environment. The data were acquired from a long-term experiment at the Rimski Šančevi experimental station of the Institute of Field and Vegetable Crops, Novi Sad, Serbia. Observed indicators were compared by using datasets from 2001 to 2010, across five maize cropping systems. Maize continuous cropping resulted with decrease in the utilization of the agroecological potential compared with the fertilized crop rotation. Long term maize-based cropping resulted with differences in soil organic carbon content, soil pH and temporal soil NO3. However, recommended fertilizers application and crop rotation contributed to the overall agroecosystems ability to decrease the anthropogenic pressure. Accordingly, it was found that yield decrease resulted mostly from inability of the cropping systems to utilize agricultural management (tillage, fertilization, etc.) in variable environmental conditions. For the investigated trial the performance based index showed that a 2-year maize cropping had the highest capacity for sustainable maize growing. | en |
dc.description.abstract | U radu je prikazana analiza indeksa performansi agroekosistema koja može da posluži kao osnova za unapređenje gajenja kukuruza. Indeksi performansi sistema gajenja kukuruza su korišćeni u cilju razdvajanja njihove efikasnosti u ostvarivanju visine prinosa, količine biljnih ostataka, kruženja hraniva i regulaciji gasova staklene bašte. Korišćeni indikatori su indirektni pokazatelji koji služe za sumiranje i pojednostavljenje tumačenja kompleksnog uticaja agroekosistema na životnu sredinu. Za obračun su korišćeni podaci sa višegodišnjeg ogleda 'Plodoredi' Instituta za ratarstvo i povrtarstvo iz Novog Sada, a praćeno je pet različitih sistema gajenja kukuruza. Istraživani sistemi ratarenja, posmatrano u dužem vremenskom periodu, značajno su uticali na svojstva zemljišta, što je dovelo do razlika u sadržaju organske materije, pH vrednosti i zemljišnog NO3. Međutim, pravilno postavljena tehnologija gajenja kod đubrenih polikultura kukuruza je uspešno kompenzovala antropogeni uticaj. U skladu sa tim, istraživanja su pokazala da opadanje prinosa dolazi kao rezultat smanjene efikasnosti pojedinih sistema gajenja kukuruza da iskoriste efekte primenjene agrotehnike (đubrenje, obradu) pri varijabilnim klimatskim uslovima. Utvrđeno je da dvopolje kukuruza ima najveći indeks efikasnosti i sposobnost da raspolaže resursima agroekosistema, dok neđubrene parcele dugoročno nemaju mogućnost očuvanja agroekosistema. | sr |
