o:12784 Ispitivanje uticaja konvencionalnog, integralnog i organskog sistema gajenja na produktivnost, kvalitet i biološku vrednost krompira doktorska disertacija The influence of conventional, integrated and organic farming systems on productivity, quality and biological value of potato : doctoral dissertation sr U trogodišnjem periodu (2013-2015. godina) na području severne Bosne (region Lijevče polja na lokalitetu u ataru sela Laminci, KO Gradiška) na zemljištu tipa aluvijum ispitivan je uticaj konvencionalnog, integralnog i organskog sistema gajenja i odabranog sortimenta na produktivnost, kvalitet i biološku vrednost krompira. U cilju rešavanja postavljenog zadatka ogled je izveden kao dvofaktorijalni u split-plot sistemu u četiri ponavljanja, sadnjom semenskih krtola sledećih sorti krompira: Marabel, Jelly, Red Fantasy i Laura. Najveći broj primarnih nadzemnih izdanaka po biljci u trogodišnjem proseku posmatrano po ispitivanim sistemima gajenja ustanovljen je kod konvencionalnog sistema gajenja 4,20, zatim nešto manji kod integralnog 4,04, dok je najmanji broj PNI po biljci konstatovana u organskom sistemu gajenja 3,73. Prema očekivanju, najveći broj krtola po biljci utvrđen je konvencionalnom sistemu gajenja - 16,53, zatim u integralnom sistemu gajenja - 15,79, dok je najmanji broj krtola po biljci ustanovljen u organskom sistemu gajenja - 12,64. Broj krtola po biljci u trogodišnjem proseku varirao je u uskom intervalu po ispitivanim sistemina gajenja. Između ispitivanih sistema gajenja utvrđene su vrlo značajne razlike u prinosu sitnih krtola. Posmatrano po sistemima gajenja najveći prinos sitnih krtola u trogodišnjem proseku ustanovljen je u konvencionalnom sistemu - 4,79 t ha־¹, zatim u integralnom - 4,57 t ha־¹, dok je najmanji konstatovan u organskom sistemu gajenja - 3,71 t ha־¹. Kao što je i očekivano u sve tri godine ispitivanja najmanji prinos tržišnih krtola konstatovan je u organskom sistemu gajenja, dok je najveći prinos tržišnih krtola ostvaren u konvencionalnom sistemu gajenja. Posmatrano po sistemima gajenja najveći prinos tržišnih krtola u trogodišnjem proseku ustanovljen je u konvencionalnom sistemu - 54,04 t ha־¹, zatim u integralnom - 51,45 t ha־¹, dok je najmanji prinos tržišnih krtola konstatovan u organskom sistemu gajenja - 36,46 t ha־¹... In the three-year period (2013-2015 years) at the area of northern Bosnia (region of Lijevče polje, location near village of Laminci, Gradiska KO) the influence of conventional, integrated and organic growing systems on productivity, quality and, biological value of potatoes was investigated for the choosen assortment on the alluvium soil type. In order to solve given goals, the experiment was conducted as two factorial in a split-plot design with four replications, by the planting of the seed tubers for following varieties: Marabel, Jelly, Red Fantasy and Laura. The largest number of above ground stems per plant in three-year average by the studied systems observed, was growing up whitin conventional farming systems 4.20, then slightly less in the integral-one 4.04, while the lowest number of stems per plant was measured in an organic cropping system 3.73. As it was expected, the largest number of tubers per plant was determined by conventional farming system - 16.53, followed by the integrated cropping system - 15.79, while the lowest number of tubers per plant was established in the organic farming system - 12.64. Number of tubers per plant in three-year average fluctuated in a narrow interval among tested growing system of cultivation. Highly significant differences in the yield of small tubers were found between tested farming systems. Looking among tested farming systems, the highest yield of small tubers in the three-year average was established in the conventional system - 4.79 t ha־¹, then integrated - 4.57 t ha־¹, while the lowest yield was obtained in organic cropping system - 3.71 t ha־¹. As it was expected, in all three years of investigation, the lowest yield of marketable tubers was found in the organic farming system, while the highest yield of marketable tubers was achieved in conventional system.The highest yield of marketable tubers concerning three-year average data were established in the conventional system - 54.04 t ha־¹, then in the integral-one - 51.45 t ha־¹, while the lowest yield of marketable tubers was measured in organic cropping system - 36 46 t ha־¹...
