This research was conducted in Huaynas village, Huaso district, Julcán province, in La Libertad department, in the ecological zone “Praire Very Humid Montane” at an elevation of 3887 meters above sea level during the months of January to September of 2015. Two monogerm sugar beet cultivars were used: SVPE 14-02 and SVPE 14-03. The objectives of this study were: a) determine the suitability of cultivars SVPE 14-02 and SVPE 14-03 to puna’s weather conditions; b) determine the effect of nitrogen fertilization in the production of sugar beet cultivars; c) determine which of the studied cultivars produce higher yields. To achieve these objectives, two experiments were installed (one per cultivar) with a seeding density of 150 000 plants per hectare, with three nitrogen doses: 0 kgN.ha-1 , 100 kgN.ha-1 and 200 kgN.ha-1 . It was found that cultivars SVPE 14-02 and SVPE 14-03 do adapt well to the ecological zone “Praire Very Humid Montane”; resisting frost well but not prolonged periods of drought in the initial stage of the vegetative cycle. Under puna’s weather conditions, and extreme drought, cultivar SVPE 14- 02 produced higher yields (on average 0.62 t.ha-1 , with a maximum of 1.6 t.ha-1 ) than those obtained by cultivar SVPE 14-03 (on average 0.2 t.ha-1 ), in the treatment N2 with 100 kgN.ha-1 . Water stress in both studied cultivars was limiting for the normal development of sugar beet plants and, consequently, for obtaining higher crop yields per hectare.
