In field trials in 1986 and 1988 on sandy loam soil at Kalyani, West Bengal, groundnut JL 24 seeds were inoculated with Rhizobium and/or treated with 1 p.p.m. cobalt sulphate or the crop was given an application of 25 mg cobalt sulphate/msuperscript 2. Seed yield was increased by all treatments compared with the untreated control. Seed yields were lower with soil-applied cobalt sulphate (1.52 t/ha) than with the other treatments (1.72-1.77 t/ha).
