Abstract


Field experiments were conducted at Agricultural Research Station, Aliyarnagar. Tamil Nadu, India during summer 1994 and 1995 on groundnut. Results revealed that irrigation scheduled at 0.75 IW/CPE ratio registered higher uptake of macro nutrients and higher soil available N. P and K compared to 0.60 1W/CPE. Uptake of nutrients by groundnut and post harvest soil available nutrients were higher at higher level of fertilisation and organic amendments application. Though irrigation and fertiliser levels did not influence organic carbon content. application of organic amendments significantly increased the organic carbon content of the soil.
