Sortne specifičnosti karfiola na prinos i sadržaj nitrata
Varietal specificities in yield and nitrate content in cauliflower
Univerzitet u Kragujevcu, Agronomski fakultet, Čačak, Srbija
Sažetak
Azotna đubriva, pored toga što su značajni činioci u ostvarivanju visokih prinosa, mogu predstavljati izvor intenzivnog zagađenja zemljišta, pri čemu se povećane količine azota, posebno nitratnog oblika, usvajaju od strane biljaka. U cilju ispitivanja uticaja đubrenja azotom na prinos karfiola i akumulaciju nitrata u ruži karfiola, postavljeni su ogledi sa dva genotipa karfiola (sorta Snežna grudva i hibrid Nautilus F1), primenom rastućih doza azota- 80,120 i 160kgN/ha, u vidu prihranjivanja sa KAN-om. Dobijeni rezultati pokazali su tendenciju porasta svih ispitivanih parametara (masa ruže, prečnik ruže i ukupan prinos) sa povećanjem doze azota, sa prosečnim sadržajem nitrata u ruži karfiola kod sorte 1124 mg/kg i 733 mg/kg kod hibrida.
Abstract
Apart from being important factors in producing high yields, nitrogenous fertilizers can act as sources of intensive soil pollution, with increased amounts of nitrogen, particularly of its nitrate form, being up taken by the plant. To examine the effect of nitrogen fertilization on cauliflower yield and nitrate accumulation in the cauliflower curd, the trials were set up involving two cauliflower genotypes (variety Snowball and Nautilus F1 hybrid), applying increasing nitrogen rates - 80,120 and 160kgN/ha broadcast as CAN (calcium ammonium nitrate). The results obtained showed that there was a rising tendency in all the parameters examined (curd weight, curd diameter and total curd yield), concurrent with nitrogen rate increases, the average nitrate content in the cauliflower curd being 1124 mg/kg in the variety and 733 mg/kg in the hybrid.
