| Description
| - Between 2010 and 2012 various ways and dates of mineral nitrogen fertilizer applications were studied in potatoes under conditions of potato production region of the Czech Republic. Variants including pre-plant broadcast application of full N rate (100 kg/ha) in urea and DAM 390 were compared to variants, where a half of N rate was pre-plant and a half was post-emergently applied (prior to intensive nutrient uptake by potato plants) using equipment for ridge application (liquid DAM 390). A variant containing post-emergent application of full N rate into ridges was also included. For application of liquid fertilizer into ridges a functional model of applicator designed for these purposes was used. Two potato varieties differing in growing period duration (very early Magda and medium-early Janet) were involved in the trial. The best yield results in both varieties were recorded for the variant of split mineral N rate applied prior to planting and after emergence. The variant of applying full N rate into ridges after crop emergence was not effective with regard in yield. Further, an impact of evaluated variants was studied on potato tuber mechanical resistance, which is an important parameter of potato quality during storage and post-harvest handling. Tuber samples were subjected to precisely defined load in loading simulator. Subsequently, the rate of tuber damage was measured based on colour changes in flesh. The highest effect on results was recorded for variety. Evaluating the impact of variants, tendentially increased susceptibility to mechanical damage was determined in potatoes derived from variant involving pre-plant urea application with full rate and variant involving full N rate in DAM 390 post-emergently applied into ridges.
