A field experiment was conducted at RAU, Pusa to rationalize use of phosphours in a rice wheat cropping system grown in caleareous silty soil of Bihar plains. Distinct positive response to P was observed by skipping its application in either crops without scarifying yield and economic returns. However, it was more appropriate to skip in wet season for rice alone or by reducing P application dose by 50% for both crops.
