1988
Azad A.S. | Gill A.S.
The response to different applications of phosphorus fertilizer (0, 10, 20, 30 and 40 kg P2O5/ha) was measured at three sites in the Gurdaspur district of Punjab during the 1982/83 season. All phosphate treatments yielded significantly more than the control. The response to phosphate fertilizer was linear. The maximum mean yield of 758 kg/ha was recorded with the 40 kg P2O5/ha treatment producing 12 kg grain yield/kg NPK fertilizer with a return of RS 12/rupee invested in fertilizer. The response to the application of phosphorus fertilizer was greatest in soils with a low available phosphorus status.
