Parametri rodnosti i kvalitet zrna jarog ovsa

Abstract

Istraživanje je izvedeno na Oglednom polju Centra za strna žita u Kragujevcu. U radu su prikazani rezultati istraživanja kragujevačkih jarih sorti ovsa (Slavuj i Lovćen). U dvogodišnjem poljskom ogledu istraživan je prinos zrna, masa 1000 zrna i hektolitarska masa u zrnu dve sorte ovsa. Prosečan prinos zrna kod ispitivanih sorti ovsa kretao se u intervalu od 2,190 t ha-1 do 3,150 t ha-1. Prinos zrna značajno se razlikovao između godina i u proseku za sve genotipove bio je viši u 2013. godini u odnosu na 2012. godinu. Prosečne vrednosti mase 1000 zrna kod ispitivanih sorti ovsa kretale su se u opsegu od 27,60 do 35,33 g. Na osnovu analize varijanse, kod istraživanih sorti ovsa ustanovljene su vrlo značajne razlike za masu 1000 zrna i značajne razlike prinosa zrna u odnosu na faktore spoljašnje sredine, odnosno godine istraživanja.

The investigation was carried out on the experimental field of Small Grains Research Center, Kragujevac. This paper presents the results of Kragujevac cultivars of spring varieties oats (Slavuj and Lovćen). Grain yield, 1000 kernel weight and test weight in grain two cultivars of oats was determined in a two-year field experiment. Average grain yield of oat cultivars ranged from 2.190 t ha-1 to 3.150 t ha-1. Grain yield differed significantly between years and the average of all cultivars was higher in 2013. compared to 2012. Average values of 1000 grain weight of oat cultivars varied in the range from 27.60 to 35.30 g. Very significant differences in 1000 grain weight at investigated oats cultivars were found relative to the cultivar and significant differences at yield relative to environmental factors, respectively the year of investigation.
