Effect of NPK on phosphorus uptake by sunflower at different stages of growth

Abstract

The application of higher levels of N (80kg), P205 f120 kg) and 40 kg K20/ha increased the P uptake of sunflower plants at vegetative and flowering stages. The P uptake in plants at harvest stage was increased by the addition of 40 kg each of N and K2Q and 60 kg P205/ha.
