Notes:
Summary E-, L-values growing mungbean and A-values growing maize, mungbean, urdbean and cowpea were assessed in P and farmyard manure enriched soil of permanent manurial trial at Pantnagar, Nainital of India. E- and L-values were found to increase in farmyard manure and P enriched soil while L-values remained constant at different dates of harvesting. A-values varied with fertility status of soil and the kip of crop. Maize gave higher A-values than pulses. In all crops, higher A-values were found with enrichment of farmyard manure and phosphorus. E-, L- and A-values gave significant correlations with yield and P uptake in pot experiments. E-, L- and A-values were good in assessing the availability of soil phosphorus. However, E-value is a rapid technique as it measured in laboratory without involvement of plant.
