Abstract: During the study of orsenic (,4s) /plan/ parts. a pot experiment in As condition 11·ith different doses of arsenate rAs\') viz .. 20. 30, 50 ppm and control Hilhfour popular rice varieties viz. friguna, IR 36. PNR 519 and JET -17\"i6 was conducied It iras observed that availability of phosphorus (PJ conce11tration in soil iras increased after irrigation ll\'ith As\'.
