Productivity traits of rye (secale cereale), khorasan wheat (triticum turgidum, ssp taranicum mckey) and quinoa (chenopodium quinoa willd) grown on degraded soil

Abstract

The productivity traits of rye, khorasan wheat and quinoa on degraded soil were investigated in a three-year research (2010-2012). The research was carried out in two localities: Stanari (ST) (Bosnia-Herzegovina) and at "TENT 2" in Obrenovac (OB) (Serbia). A significant interdependence between grain yield and aboveground biomass yield was observed in the investigated genotypes and localities. The resulting average grain yields in these localities ranged between 1,166-1,702 kg ha-1 (rye), 1,826-1,943 kg ha-1 (khorasan wheat) and 520-966 kg ha-1 (quinoa). Fluctuations in grain yields were due to different soil conditions different nutrient contents and the distribution of precipitation at initial stages of crop development. This research confirmed that rye is a crop with minimum soil requirements and it can be successfully grown in poor soil. The second best biomass yield was obtained by khorasan wheat, while the lowest biomass yield was obtained by quinoa.
