A field experiment was carried out in Indian Institute of Soil Science, Bhopal to study the effect of different dose of phosphorus on the phosphorus acquisition pattern in different varieties of soybean (Glycine max L.) under rainfed conditions in black soil. The experiment was laid out in factorial RBD with 3 replications. There were four phosphorus levels viz. 0, 30, 60 and 90 kg ha-1 phosphorus and four varieties of soybean viz., JS 9560, JS 9305, JS 335 and JS 9752. The results revealed that the variety JS 9752 is better in phosphorus acquisition and yield. Grain yield showed a linear increase only up to 60 kg ha-1 phosphorus in all the varieties. Among the varieties, JS 9752 has given the highest grain yield on supply of 60 kg ha-1 phosphorus. Phosphorus uptake and use efficiency were also were highest for the variety JS 9752 followed by JS 9560 in all the treatments. Hence it is concluded that JS 9752 is the most efficient variety among the four in terms of yield and phosphorus uptake followed by JS 9560.
