Uticaj mineralne ishrane na prinos pšenice

Abstract

Cilj ovog istraživanja bio je da se ispita uticaj mineralne ishrane na prinos ozime pšenice sorte (Lazarica, Takovčanka, KG 56S, KG 100 i Ana Morava). Za ova istraživanja su izvedena dva ogleda (N1-80 kg/ha i N2-120 kg/ha). Studija je pokazala da je najveći prinos kod ispitivanih sorti pšenice postigla sorta Takovčanka (5,362 t/ha) sa kombinaciom đubrenja 120 kg/ha N,60 kg/ha P2O5 i 60 kg/ha K2O. Masa 1000 zrna kod ispitivanih sorti pšenice značajno je varirala zavisno od genotipa, a najveća prosečna masa hiljadu zrna (45,48 g) ustanovljena je kod sorte pšenice Takovčanka sa kombinacijom đubrenja N80P60K60.

Investigations were carried out during the 2007/2008 year at the Center for Small Grains in Kragujevac. The objective of this study was to investigate the influence of mineral nutrition on the yield of winter wheat varieties (Lazarica, Takovčanka, KG 56S, KG 100 and Ana Morava). Two experiments were conducted (N1-80 kg/ha and N2-120 kg/ha) in these investigation. The study showed that cultivar Takovčanka achieved their highest grain yield (5. 362 t/ha) with a fertilizer combination of N120P60K60. Thousand grain weights significantly varied across cultivars, and cultivar Takovčanka achieved the highest average value (45. 48 g) with a fertilizer combination of N80P60K60.
