Abstract

The study on the uptake of five major nutrients by Hookah tobacco (N-rustica) and their distribution in leaf, stem and suckers showed that tobacco suckers shared nearly 30 per cent of P₂O, and were also rich in other nutrients. The pattern of dry matter production and uptake rate of different nutrients indicated the major influence of mean temparature rather than age of the crop. Nitrogen fertilization increased the uptake of all the nutrients studied by virtue of higher dry matter production while chemical suppression of suckers resulted in higher uptake of nitrogen, potassium, calcium and magnesium. Similarly wet soil moisture regime recorded higher nitrogen, potassium and calcium uptake, while magnesium uptake was better under dry regime with no change in phosphorus uptake due to soil moisture variations.
