EFFECT OF N LEVELS AND SOILS ON THE N, P AND K UPTAKE BY MAIZE

Abstract

Pot culture experiment conducted with fifteen soils (ten representing low N and five medium N soils) under graded doses of N to study the uptake of nutrients revealed that the N P K uptake showed a positive trend with N application at all stages of crop growth. Application of 202.5 Kg N/ha recorded the highest N uptake by shoot and grain. The N uptake was higher in medium N soils compared to low N soils.
