Summary

A field experiment was made at the Indian Agricultural Research Institute, New Delhi to compare the efficiency of Mussoorie rock phosphate with ordinary superphosphate for two forage legumes, cowpea (Vigna sinensis Savi) and cluster beans (Cyamopsis tetragononoloba L.) and residual effects were studied in wheat (Triticum aestivum L.). For both the forage legumes Mussoorie rock phosphate was only 22% as effective as ordinary superphosphate (on soil of pH 7·1) and it had no significant residual effects on wheat even when the application rates supplied three times as much P as was supplied by ordinary superphosphate.
