Summary

Nine strains of Rhizobium sp. were studied in vivo for their nodulation capacity, leghaemoglobin content, grain yield, crude protein and 16 amino acids content, in the chick pea variety C 235 grown on a calcareous saline alkali soil. There was no significant correlation between grain yield and number of nodules (r = 0·37) or dry weight of nodules (r = 0·29), but grain yield was significantly correlated with leghaemoglobin content of nodules (r = 0·95). Of the 16 amino acids analysed in seed samples, aspartic, glutamic, proline and histidine were greatest with strain H 45; glycine, leucine and arginine with strain F 6; norleucine, tyrosine and phenylalanine with strain KG 38; and alanine and valine were greatest with strain KG 41. Strain KG 38 led to significantly higher grain yield than the other strains.
