Effect of potato tubers origin and weight on the yield of potato variety Desiree in western Serbia

Abstract

The aim of this study was to determine the effect of the size and weight of tubers originating from different altitudes on the yield of most commonly grown potato cultivar Desiree in western Serbia (Macva). Potato seed producing crop, from which the planting material came from, was grown during 2006 and 2007 at two sites with different altitudes: a plain region at 72 m a.s.l. and a mountainous region at 1100 m a.s.l. The investigation was carried out by planting the following mass of planted material: 50 ± 5g, 70 ± 5g, 90 ± 5g and 110 ± 5g in 2007 and 2008 year to produce planting material. Planted tubers originating from 72 m a.s.l. produced a total yield (a two year average) of 26.25 t ha-1. The difference was significantly higher than the variant with planted tubers originating from 1100 m a.s.l. by 2.02 t ha-1 (7.7%). The two year mean highest total yield of 27.87 t ha-1 was achieved by planting the largest mass (110 g) and the lowest 21.07 t ha-1 by planting the smallest mass (50 g) of the tuber. Higher yields of potato tubers in moist conditions in western Serbia (Macva) were achieved by planting larger mass of tubers originating from lower altitude.
