A field study was undertaken during summer season of 2000 and 2001 to investigate effect of phosphorus application on yield attributes, seed yield, nutrient uptake, fertility build-up and monetary returns from different varieties of rajmash (Phaseolus vulgaris L.). Four levels of P (0, 30, 60 and 90 kg P,O,/ha) and three varieties of rajmash (Triloki, Baspa and SRC 74) were used in the study. Application of phosphorus up to 60 kg P,O/ha showed significant and consistent increase in plant height, pods/plant, pod length, seeds/pod, 100-seed weight, seed and straw yields and nutrient uptake. Similarly, significant varietal differences were recorded for yield and yield attributes. Triloki outyielded SRC 74 and Baspa by 46 and 62% during 2000 and by 33 and 46% during 2001 and gave the highest net return to the tune of Rs. 20971 and Rs. 20947/ha during 2000 and 2001, respectively. Likewise, maximum net returns were recorded with 60 kg P,O,/ha amounting to Rs. 18,249 and Rs. 19,962/ha during 2000 and 2001, respectively. Further, application of P significantly improved the available P status of soil
