Abstract

The deleterious effects of sorghum on crops that follow have been extensively reported upon by American workers-Bennet (1897), Ten Eyck and Shoe Smith (1906), Snyder and Osborn (1915), Willeman et. al. (1919), Vinall and Ghetty (1921), Breazeale (1924) and Conrad (1927, 1928, 1932 and 1937). Fletcher (1912) observed the adverse effects of sorghum on a succeeding crop of Sesamum indicum in experiments con- ducted by him in Surat, Bombay. Ramanatha Ayyar and Sundaram (1941) have recorded that similar to their observations on the black soils of Tinnevelly, the harmful effects of sorghum have been noted under conditions obtaining in the Coimbatore, Salem and South Arcot districts of the Madras Presidency. Breazeale (1. c.) however states that in Chine, sorghum is grown year after year upon the best land and that no injurious effects have been visible.
