Effect of multi-nutrient complex fertilizers on growth and tuber yield of very early potato (Solanum tuberosum L.) cultivars

Abstract

A b s t r a c tThe aim of the study was to compare the effect of multi--nutrient complex fertilizers (HydroComplex, Nitrophoska Blue Special and Viking 13 from the nitrophoska group, and Polimag S from the amophoska group) and single-nutrient fertilizers on the growth and tuber yield of very early potato cultivars ('Aster', 'Fresco', 'Gloria'). The field experiment was carried out on podzolic soil in mid-eastern Poland during [2005][2006][2007]. The study showed a greater beneficial effect of HydroComplex and Nitrophoska Blue Special on the growth of very early potato cultivars than that of Viking 13 and Polimag S. The application of HydroComplex and Nitrophoska Blue Special resulted in greater above-ground plant biomass and assimilation leaf area compared with single-nutrient fertilizers; the leaf area index (LAI) was higher by 0.28 and 0.32, respectively. The differences were smaller and not statistically confirmed with the use of Polimag S and Viking 13. When the multi-nutrient complex fertilizers were applied, leaf weight ratio (LWR), leaf area ratio (LAR) and specific leaf area (SLA) were similar to the single-nutrient fertilizers. Of the multi-nutrient complex fertilizers, only Nitrophoska Blue Special resulted in higher tuber yield, on average by 2.40 t × ha -1 , compared with the single-nutrient fertilizers. The studied cultivars showed a similar response to applied fertilizers. LAI for 'Gloria' was higher than for 'Aster' and 'Fresco', with smaller LAR found in 'Gloria'. LWR for 'Fresco' was smaller than for 'Aster' and 'Gloria', with higher SLA found in 'Fresco'. The tuber yield of 'Aster" (24.04 t × ha -1 ) was higher on average by 3 t × ha -1 than for 'Fresco' and 'Gloria'.

Effect of fertilizers with different chemical composition on crop yield, nitrogen uptake and leaching in a sandy loam Luvisol

“…In this treatment, compared to complex fertilizers, the tuber yield was by 5.4-7.8% lower (P < 0.05), fewer large tubers (more than 6 cm) were formed, potatoes contained less starchy and accumulated more nitrates (P < 0.05) ( Table 2). Studies by Wadas and Dziugel (2013) on the effect of various complex and simple fertilizers on potato yield have also revealed that complex fertilizers, as compared with simple fertilizers, better enhance the development of the aboveground part and tubers, but of the tested complex fertilizers, only Nitrophoska Blue Special resulted in higher tuber yield, on average by 2.40 t ha -1 , compared with simple fertilizers.…”

Effect of different mineral fertilization technologies on the size of starch granules in potato

“…In turn, Wadas et al , who investigated complex fertilizers containing manganese and boron among others (HyroComplex, Nitrophoska Blue Special, Viking 13, Polimag S), claimed that fertilizers had no influence on the accumulation of starch by very early cultivars. A cycle of trials testing the effect of mineral fertilizers applied in a dose of 360 kg/ha NPK with added micronutrients was also completed by Rainys and Rudokas , who demonstrated the absence of any effect of fertilization on starch accumulation.…”

“…The weather conditions, atmospheric precipitation in particular, modify the quality of potato yields, especially the accumulation of starch .…”
