Abstract:
A field experiment was designed to assess the effect of K on available nutrient status of
the soil and uptake of nutrients by plants at different irrigation levels. The available nutrient
contents of N, K and exchangeable Ca were found to be increased by the application of K while
available P and exchangeable Mg content remained unaffected. Available P was more when
IW/CPE ratio was 0.50. The uptake of N was significantly influenced by the application of K only
at the full vegetative phase. Pand K uptakes were significant both at the full vegetative phase and
harvesting stage. The uptake of Ca and Mg decreased as the level of K increased except at the full
vegetative phase.
