Abstract

Field experiments comprising four levels of N(0, 80, 160 and 240 kg/ha), alone and in combination with a nitrification inhibitor CMP, revealed that the uptake of B, Zn, Mn and Fe by potato plant increased with the advancement of crop growth. The N application had a positive effect on the micronutrient uptake during the growth period. In the presence of CMP, the B and Zn uptake were increased, on the other hand, the Mn and Fe uptake were decreased. A crop of 100 q fresh tubers inclusive of its haulms on an average removed 37 g B, 88 g Zn, 134 g Mn and 749 g Fe/ha.
