Abstract:
A field experiment was conducted to know the influence of P fractions on P uptake, yield and nutrient content. The nutrient uptake in plant at harvest was recorded the N uptake in plant was varied from 32.92 to 87.52 kg ha-1 and the P uptake was 8.09 to 25.23 kg ha-1 and the K uptake in plant was ranged from 26.64 to 76.26 kg ha-1. The NPK content in plant was varied from 1.39 to 1.81%, 0.37 to 0.54% and 1.18 to 1.72% respectively. The pod yield of ground nut at harvest was ranged from 1099 to 2683 kg ha-1. The haulm yield of groundnut was ranged from 2019 to 4889 kg ha-1. Before sowing pod yield was positively correlated with the P fractions like Al-p (0.536**), Fe-P (0.470**), Occluded P (0.540**), Ca-P (0.515**), organic P (0.314*) and total P (0.380*). At harvest positive relationship between the pod yield with the P fractions except with the Ca-P (0.033). Before sowing while the P uptake did not correlate with the Al-P (0.130), Fe-P (0.184), Occluded P (0.112), Ca-P (0.117), negative relation with the organic P (-0.403**) was observed. At harvest P uptake was not correlated with any of the fraction but negative relationship with the organic P (-0.320*).
