Uticaj sezone i genotipa na prinos i kvalitet zrna kod ozimih sorti pšenice

The small-scale trials over two years (2011/12th and 2012/13th), examined the six varieties of winter wheat (Vizija, Takovčanka, Planeta, Kruna and Perfekta). Studied grain yield (t ha-1), weight of 1000 grains (g) and test weight (kg hl-1). Estimates were statistically significant differences for grain yield between varieties and years. Cultivars Vizija, Takovčanka and the Planeta have conducted surveys have shown a high degree of adaptability conditions of production of wheat and had a satisfactory yield in the examined vegetation seasons.U mikroogledima tokom dve godine (2011/12.-2012/13.), ispitivano je šest sorti ozime pšenice (Vizija, Takovčanka, Planeta, Kruna i Perfekta). Istraživan je prinos zrna (t ha-1), masa 1000 zrna (gr) i hektolitarska masa (kg hl-1). Procenjene su statistički signifikantne razlike za prinos zrna između sorti i godina. Sorte Vizija, Takovčanka i Planeta su u sprovedenim ispitivanjima pokazale visok stepen adaptabilnosti uslovima proizvodnje pšenice i imale su zadovoljavajući prinos u ispitivanim godinama

Uticaj mineralne ishrane na prinos ozime pšenice (Triticum aestivum L.)

Investigations were carried out during the 2006/2007 year on stationary field trial, 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 i Ana Morava). For these investigations were conducted two experiments (N1-80 kg ha-1 and N2-120 kg ha-1). Analysis of variance indicates very significant effects of cultivar on the grain yield, 1000-grain weight and test weight. Analysis of variance for the impact of nitrogen rates (N1 and N2) on investigated traits was found that doses of nitrogen in combination with NPK fertilizers significantly affected only on grain yield.Istraživanja su izvedena tokom 2006/2007. godine na stacionarnom poljskom ogledu, Centra za strna žita u Kragujevcu. Cilj ovog istraživanja je bio 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-1 i N2-120 kg ha-1). Analizaom varijanse je utvrđen vrlo visoko značajan uticaj sorte na prinos, masu 1000 zrna i hektolitarsku masu. Analizom varijanse za uticaj doze azota (N1 i N2) na ispitivane osobine utvrđeno je da su doze azota u kombinaciji sa NPK đubrivima značajno uticale samo na prinos zrna
