UTILIZATION OF NITROGEN, PHOSPHORUS AND POTASSIUM FROM COMPLEX FERTILIZERS BY VERY EARLY-MATURING1POTATO CULTIVARS
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2015, Vol 14, Issue 2
Abstract
Potato has a relatively shallow root system and requires significant nutrient inputs to maintain tuber productivity and quality. Efficient application of the proper type and amount of fertilizer plays an important role in achieving profitable tuber yield with minimum nutrient loss to the environment. The aim of this study was to compare utilization of nutrients from NPKMgS-type fertilizer complex from the nitrophoska (HydroComplex, Nitrophoska Blue Special, Viking 13) and amophoska group (Polimag S), and single-nutrient fertilizers (ammonium nitrate, superphosphate, potassium sulphate) by very early-maturing potato cultivars (Aster, Fresco, Gloria) on loamy sand soil. Nutrient utilization from fertilizers was calculated as a percentage ratio of the difference between the amount of nutrient uptaken by potato tubers in treatment with particular fertilizers, and nutrient uptake by potato tubers in the control treatment without fertilizers, to the quantity of the nutrient applied in particular fertilizers. With the use of complex fertilizers with microelements from the nitrophoska group, i.e. Nitrophoska Blue Special and HydroComplex, nitrogen, phosphorus and potassium utilization by potato tubers was higher than that obtained using the single-nutrient fertilizers. The use of these fertilizers produced better results for plant growth under well-watered conditions. With the use of complex fertilizers from the nitrophoska group without microelements (Viking 13) and from the ammophoska group (Polimag S), the nutrient utilization was similar or lower than with the application of single-nutrient fertilizers. The highest nutrient uptake along with potato tuber yield was reported with the application of Nitrophoska Blue Special; the nitrogen uptake was higher by 10.05 kg·ha-1, phosphorus by 1.84 kg·ha-1, and potassium by 11.41 kg·ha-1 in comparison with single-nutrient fertilizers. When this fertilizer was applied, utilization of nitrogen (21%), phosphorus (9%) and potassium (23%) by very early-maturing potato cultivars was almost twice as high as with single-nutrient fertilizers. The uptake and utilization of nitrogen, phosphorus and potassium by potato tubers depended on the cultivar, and was determined by weather conditions during the potato growing season.
